IPCC 2019 Report: Climate Change and Land
A few days ago ago the IPCC published the report Climate Change and Land. This report is a must read by all New Zealand Members of Parliament to enable them to cast informed votes on behalf of New Zealand citizens. The IPCC report reinforces the conclusions and recommendations of the World Resources Report (see my 8 August 2019 blog). I once again request all Members of parliament to cast conscience votes on issues of climate change mitigation instead of voting along party lines.
A summary of the report for policymakers and chapters of the full report can be downloaded from here
The CarbonBrief website has an excellent review of the report - link here
Jeremy Leggett has put together a slide show of the summary which can be downloaded from here by selecting the file: 190808 IPCC report - Impacts.pptx

Immediate reduction in methane gas emissions from cows to avert runaway emission of methane from thawing tundra
Yesterday I received a forwarded email from Greenpeace which states the following:
“Hi friends and family,
Right now, an area the size of Switzerland is on fire in the Arctic, July was Earth's hottest month ever recorded and Greenland just lost 12 billion tons of ice, in a single day. This is a climate crisis, and we have to act.
Around New Zealand and the world, people are sounding the emergency alarm and uniting to take action - but the NZ Government is failing to deal with our worst climate polluter - agriculture.
The Government has just put out a weak and dangerous proposal to “deal” with agriculture’s emissions. It suggests minor and incremental changes that lets the dairy industry off the hook again, and leaves the rest of is subsidising their climate pollution.
What we desperately need to fight the climate crisis is fewer cows and a rapid transition away from intensive dairying towards plant-based regenerative farming.
The Government has asked for public feedback on their proposal, so it’s vital that you have a say now, in no uncertain terms.
Greenpeace has set up a quick and easy page that you can use to make a quick submission:
I've done one, please take a couple of minutes now to join me, numbers are vital.”
I have added my personal comments to the above Greenpeace petition as follows:
“In 1972 John Maddox, then Editor of the international journal Nature, dismissed environmentalists’ concerns about climate change and global pollution as being overly alarmist in his book The Doomsday Syndrome. Maddox conceded that developing technology can lead to unintended consequences, but asserted that technology, human ingenuity, and social structures were able to rectify potential problems before they escalated. History has demonstrated that Maddox was wrong. Early warnings about climate change in the 1970s went unheeded and in hindsight we can now clearly see that 40 years ago the precautionary principle should have been adopted. Governments should have protected the public from harm when scientific investigation had established a plausible risk.
We now face another plausible risk which has been verified by recent research by IPCC. There is currently a risk of major methane gas releases from thawing tundra which could lead to an irreversible change in the global climate despite the best efforts of all countries to reduce greenhouse gas emissions. The mechanism of a potential runaway is well established. The exact timing of such a runaway is currently in doubt.
New Zealand has already made a commitment to reduce greenhouse gas emissions. The question is what are the most effective and quickest methods of doing so. Carbon capture by planting trees takes time. Trees do not fully mature overnight. It will take time to replace fossil fuel based infrastructure with that of renewable energy, and the transport sector will take time to transition from fossil fuels to renewable energy. The agricultural sector provides an opportunity to reduce greenhouse gas emissions overnight. An immediate 10% culling of our herds of cows would result in an immediate 5% reduction in our greenhouse gas emissions. Many countries subsidise their agricultural sectors and many countries have paid farmers not to grow crops so as to maintain price levels. New Zealand can do the same to enable farmers to transition to alternative food production. The 2019 World Resources Report - Creating a Sustainable Food Future: A Menu of Solutions to Feed Nearly 10 Billion People by 2050 – “… focuses on technical opportunities and policies for cost-effective scenarios to meet food, land-use, and greenhouse gas emissions goals in 2050.” A reduction in the herds of cows is one of a number of methods endorsed by the report. All other methods take time for transition.
My message to all Members of Parliament is that the risk of a runaway of methane gas emissions due to the thawing of tundra is plausible and the longer we delay in reducing greenhouse gas emissions, the greater is the risk. All Members of Parliament have a duty of care to protect the public from harm. One way to carry out this duty is to cast a conscience vote to implement an immediate reduction in greenhouse gas emissions by requiring the agricultural sector to fully participate immediately in the mitigation process.”

Modified copy of email to SCAN: New Zealand Member of Parliament Conscience Vote on the Zero Carbon Amendment Bill
The Ministry of the Environment (MFE) document of advice to the Minister for Climate Change forms a background to the Zero Carbon Amendment Bill. In my opinion, all Members of Parliament should read this document before voting on the Zero Carbon Amendment Bill. The 186-page document (download here) includes a brief summary of New Zealand citizens' 2018 submissions to the MFE on pages 31 to 32.
I wonder how many Members of Parliament have actually bothered to read all pages of the above document so as to understand and take onboard the bases of MFE's advice. Although Member of Parliament voting on the Zero Carbon Amendment Bill should be a conscience vote to safeguard our future, I suspect that negotiations between all political parties prior to voting and final voting has been and will be based on party lines rather than fully informed decision-making. It is the political process that we are up against.
As I have stated in my previous posting on 19 June 2019, regardless of action at government level, a large degree of public focus on action should be on action at a local family and individual level. It is population growth and excessive consumption of energy and materials that has caused climate change, and we can all immediately participate in mitigating the impact of climate change by reducing our consumption levels. Any savings we make by doing so should be invested in renewable energy and infrastructure, otherwise expenditure of savings on additional goods and service other than renewable energy will contribute towards additional greenhouse gas emissions thus exacerbating climate change. Initial investment in renewable energy and infrastructure will also result in greenhouse gas emissions, but these emissions will in due course be offset by subsequent reductions in emissions by replacing the burning of fossil fuels with renewable energy.

Modified copy of email to SCAN: Climate Change Action Needed at Personal Level
Climate change is a symptom caused by population growth and growth in the per-capita consumption of materials and energy. All consumption using fossil fuels results in greenhouse gas emissions and there are physical and thermodynamic limits to the extent that the economy and wellbeing can be decoupled from energy. If all nations were to adopt a Zero Population Growth (ZPG) policy and births immediately were to equal deaths, then the world population would continue to grow due to population momentum until it stabilised decades later this century. In order to reduce greenhouse gas emissions, we therefore need to reduce our per capita consumption of materials and energy. There have been delays in climate change action by most countries and the global rate of greenhouse gas emissions has subsequently yet to decline. The news media tends to focus on activists demanding action at the government level while glossing over the need for families and individuals to undertake action at a personal level. It is the inaction of not only governments and local authorities, but also families and individuals that has contributed to climate change. Changes in the consumption behaviour by families and individuals are needed to help mitigate the impact of climate change. Even though our current economic and government systems restrict what can be easily changed - examples include provision of public transport, water, electricity, and transport and communication networks - there are nonetheless many changes in actions that families and individuals can undertake.
Families and individuals need to realise that action starts at home. Action means being more frugal and accepting of the principles of sufficiency. The most effective ways of reducing greenhouses gases at the family and individual level have been well known for decades, and these actions can be listed in the order of Maslow's hierarchy of needs, starting with physiological needs.
Food & water
Methane gas belched out to the atmosphere by ruminants is initially more potent than CO2 and contributes about 50% of global greenhouse gas equivalents. The most effective and immediate way for families and individuals to reduce greenhouse gas emissions is to eat less meat or no meat at all. There are alternative plants substitutes which can provide necessary proteins and the minerals of milk. Many crops fed to animals are crops that can be eaten directly by humans. Land used for grazing can be planted back into forests which can absorb and store more CO2 than grass.
Where possible, we should grow our own vegetables or alternatively buy local food grown using permaculture methods instead of energy intensive fertilisers. Food and the use of water are interlinked. All crops are dependent on water and some crops use more water than others. Crops which use less water should be given priority where water is scarce and irrigation makes use of aquifers. We should also avoid processed food and cook our own food using local staples. In doing we will reduce the need for packaging.
About 30% of food is wasted in the global supply chain from the farm to the waste bucket at home. We should buy only what we need so as to avoid wasting food. The only food products that we don’t eat should be potato peelings etc. which should be returned to a compost heap for growing more food.
Warmth and shelter
Clothing is the most efficient way to keep warm. We should not heat a room or a house and then take off our jerseys and put our thermals into a drawer. 180 C is a sufficient temperature for humans and over 200 C is excessive. It is far too easy to accommodate a higher temperature than necessary by removing clothing.
Before heating a home on a limited budget, we should make sure our home is well insulated. Insulation of housing became mandatory in 1979 and these standards have been raised in subsequent years. Most homes constructed in New Zealand before 1979 have no insulation in the walls, but the ceilings can be easily insulated where there is a roof space and likewise under-the-floor insulation can be installed where there is a crawl space.
We should question whether it is necessary to heat our entire house. Heating only the rooms we occupy is the way to go if we are on a limited budget. By all means we should buy a heat pump if we can afford one - heat pumps use 25% of the energy of a bar heater to heat a room to the same level. Ideally, houses should make use of the sun instead of needing additional heating. We should not assume our electricity bills will come down as a result of using a heat pump. Families which have shifted over to using a heat pump frequently finish up with the same previous electricity bills due to what is called the rebound effect because they adopt a higher thermal comfort level in the entire house and a higher and sometime excessive temperature on the same electricity budget.
We should use public transport more often as this is the most energy efficient form of transport. Compared to using a car, public transport involves the inconvenience of the extra time involved in travelling to the nearest pickup point, waiting for the public transport to arrive, and then the extra travelling time on board due to many stops to pick up other passengers. A more regular service will help overcome the inconvenience of waiting and a greater range of routes will reduce the distance of travelling to a local pickup point.
If we use a car, then we should reduce the number of trips in any one day by doing a single round trip, rather than multiple trips. Cars are a means of transport. The days of a car being a status symbol are over. Large and heavy SUVs are wasteful of materials and energy and are extravagant purchases. A 1500 cc automatic car is more than adequate to transport four people over the hills of Dunedin.
Electric cars imported into New Zealand are still prohibitively expensive for most families – they cost much more than a decent second hand petrol or diesel car and they have the extra burden of replacing an expensive battery. Electric cars currently sold in New Zealand weigh the same and use the same materials as petrol driven cars. The mindset of what constitutes an electric car needs to change. The ratio of the weight of an electric car to that of the passengers needs to be minimised as far as possible. A step in this direction is the two-seater Renault Twizy which is available overseas, but currently not in New Zealand.
Electric bikes have great potential, but are currently grossly overpriced in New Zealand at about $3,000. A conversion of a standard bike to an electric bike can be as low as $1,000. I would like to see the maximum power of electric bikes raised from 300 watts to 1,000 watts to handle the hills of Dunedin.
Electric scooters have potential at the price of $700, but sharing pavements is a problem. I have seen some scooters travelling faster than pedal bikes, so electric scooter could share cycle lanes.
Electric motorbikes on the road in New Zealand are now being sold at about $7,000. This price is still excessive, given that one can buy a decent petrol scooter for half the price.
It is the weather and safety factor, and also the hill factor in Dunedin, that put many people off from riding a bike whether pedal or electric. The weather and safety factor also put many people off from riding a motorbike whether petrol or electric. A solution against getting wet and cold on an electric bike or a motorbike is to use an alternative electric vehicle with a canopy such as the two-seater lightweight PEBL. A vehicle like the PEBL with 4 KW power to the wheels would handle the hills of Dunedin without the need to pedal.
The safety factor still remains a problem so long as bikes or low speed mopeds share the road with cars. One solution is to provide an absolute separation of cycle lanes from the roads used by cars. This approach has been adopted by a number of cities around the world. It is the combination of weight and the speed of the two modes of transport which are in conflict. Another solution is to reduce the speed of all modes of transport to, say, 25 or 30 kph around the city where physically separated cycle lanes are not provided.
Seth Wynes and Kimberly Nicholas have estimated the most effective ways to substantially reduce annual personal greenhouse gas emissions in their 2017 publication The climate mitigation gap: education and government recommendations miss the most effective individual actions. They are as follows:
1. Having one fewer child (an average for developed countries of 58.6 tonnes CO2-equivalent (tCO2e) emission reductions per year),
2. Living car-free (2.4 tCO2e saved per year),
3. Avoiding airplane travel (1.6 tCO2e saved per roundtrip transatlantic flight)
4. Eating a plant-based diet (0.8 tCO2e saved per year).
The list of additional actions that families and individuals can do to help reduce greenhouse gases goes on and on. The book 'How Bad Are Bananas?: The Carbon Footprint of Everything' by Mike Berners-Lee, 2011 and the website The Green Ration Book: The Costs of Everyday Living are excellent guides.
In summary, reducing greenhouse gases at a personal level means using less materials and energy by being more frugal. However, being more frugal would be self-defeating if subsequent surplus income is then used to purchase more consumption goods and services which generate greenhouse gas emissions. Surplus income enabled by adopting frugality should be invested in a transition from fossil fuels to renewable energy and infrastructure. This investment will also initially result in greenhouse gas emissions while renewables replace fossil fuels because renewables are unable to bootstrap the transition. This dynamic is a double whammy at the very same time we need to reduce greenhouse gas emissions. The key to absolute reductions is curbing unnecessary consumption.

Modified copy of email to SCAN: Recommended Documentary - "Pumped Dry - The Global Crisis of Vanishing Groundwater"
I recommend viewing the 64 minute documentary Pumped Dry: The Global Crisis of Vanishing Groundwater on YouTube.
In the last few months I have focused on collecting and processing information on the supply chains and potential bottlenecks of the technology, materials, and energy required to provide long-term sustainable and alternative energy supply systems to replace fossil fuels. This focus might seem to be esoteric to some, but in my opinion it is important to establish what is possible for future generations, rather than what our current generation wishes for based on our own recent history and personal experience.
There are supply chains that are more immediate which are related to Maslow's hierarchy of needs starting with our physiological needs of food, water, warmth, and shelter. Maslow's listing of physiological needs are actually in the wrong order of priority. Water comes before food. We can survive for weeks without food, but only a few days without water, and the supply chains of food are totally dependent on water. This is why I recommend viewing the above documentary.
It is while I was watching the above documentary that I realised that taking on board information by way of written words alone does not convey the full impact of the message. An emotional side of the message is equally important. The above documenary has both import and impact and the issue of waster rights of aquifers applies to all countries, including my own country of New Zealand.

Modified copy of email to SCAN: Recommended Book on Climate Change
I recommend the book Priority One: Together We Can Beat Global Warming by Allan Yeomans, 2007 (soft cover edition). My 2005 hard cover edition is A4 size, 492 pages.
Amazon.com describes the book as follows:
"We can do better than just slow down global warming. We can fix it. This book shows how. Increasing the organic matter in the world's soils is the only practical and cost-effective way to stop the worldwide catastrophe of global warming. By switching to sustainable energy sources that don't add carbon to the atmosphere, we can keep global warming stopped. Yet these proven solutions are poorly understood, scattered among specialties, and surrounded by confusion and conflict. Priority One shows how to combine these proven solutions so we can stabilize the world's climate, bolster lagging economies, and enhance human health. But we need to act now, before this one-time opportunity is gone."
I have found Allan Yeomans’s book to be well written and far-encompassing. What sets his book apart from other books on climate change is Chapter 9: Strategies, Guidelines, Tactics and Ploys for Marketing and Promoting Fossil Fuels and Petro-Chemical Products pages 175-327. The First Strategy titled Oil Companies and Countries Lobby to Influence World Decisions, Intergovernmental Panels and International Treaties from pages 182 to 196 makes for absorbing reading on the history of the Kyoto Protocol up until 2005. The remainder of Chapter 9 describes a number of devious and deceptive strategies adopted by the oil industry which would be under the radar of most people.
I own a 654-page book called Building Pathology: Deterioration, Diagnostics, and Intervention by Samuel Harris, 2001. This book lacks any references, but the book well compensates by being very useful. Allan Yeomans's book contains very few references to sources of information, but his book does provide detailed and carefully crafted arguments for each claim and advocacy which enables double checking as to the reliability and accuracy of the bases of his arguments.
Although I do not agree with everything that Allan Yeomans claims or advocates in his book (he is a strong advocate of nuclear energy – I still have reservations based on risk versus benefits and feasibility versus viability), whatever he writes is thorough and thought provoking.

Recomended Documentary: Ecosystem Alert
I recommend viewing the 25 minute documentary Ecosystem Alert: Protecting Lands in Peril which can be viewed on YouTube - Link here
The Aljazeera website has more information about the documentary - Link here
What was particularly striking about the documentary for me was the example of the generally unknown supply chain linkage between the large scale felling of forests and the garment industry:
The fashion industry is worth $1.7 trillion. Every year, textile manufacturers make billions of garments which might only be worn once or twice before ending up in landfill.
This so-called fast fashion is incredibly resource-intensive and one of the key drivers of biodiversity loss and deforestation.
Viscose and rayon are highly prized fabrics and demand for them is on the rise. But these materials have a dark secret. Millions of primary forest trees, thousands of years old and irreplaceable, are being used to create the pulp, which makes everything from T-shirts to jeans.
The number of trees and forests destroyed not only devastates the surrounding land but also releases tonnes of carbon back into the atmosphere."

Recommended Slideshow by Jeremy Leggett
I recommend viewing the following slideshow by Jeremy Leggett (62 slides, 21 MB download, with sources):
190604 The shortfall in progress on the provision of affordable and clean energy for all by 20130 (SDG7) and its eminent fixability. Download link here
The slideshow demonstrates that it is not only misinformation, apathy by the general public, and inaction by governments that is holding back a transition from fossil fuels to renewables.

Deletion of In Search of Steady State Revisited HelpNDoc web publication and new Key Publications HelpNDoc section
On 2 June 2019 I deleted my work-in-progress In Search of Steady State Revisited HelpNDoc web publication from this website. From now onwards this website will include only final versions of any publications.
My previous Key Publications section on this website has now been replaced with a HelpNDoc web publication which provides a search and index engine and easy flexibility of adding topics and linkages from topics to other topics.

Modified copy of email to SCAN : Reply to question and comments on my email on The Long-term Viability of Renewable Energy Systems
Thank you for your question and comments. Much appreciated. Most of the time I play my own role of devil's advocate.
First and foremost, when I refer to long-term sustainability I mean a time frame when renewable energy sources need to replace themselves repeatedly for centuries into the future. The focus of my web publication In Search of Steady State Revisited is on the direction of change required to achieve steady state. Growth cannot continue and steady state is the only way forward for our species to survive in millennia to come. Magnitudes of change are and will continue to be uncertain. A transition will happen over the next 100 years, whatever form that might be, and I assume in my web publication that the transition will eventually result in steady state. All this is covered in more detail in the completed sections of my web publication.
We have an immediate problem which is the mitigation of human-induced climate change. I am all in favour of stop gap measures which result in lower greenhouse gas emissions, even though they might not prove to be sustainable in the long-term.
All current manufacturing of renewable energy sources (wind and PV etc.) rely on the use of fossil fuels. Dynamic flow studies of the magnitude of fossil fuels required to enable a full transition from fossil fuels to renewable energy indicate that if business as usual should continue - i.e. continued growth in GDP, i.e. an increase in economic activity, i.e. an increase in the use of energy because there are limits to decoupling energy from GDP - then the per-capita use of fossil fuels will increase yet again for a number of decades before renewable energy is able to take over. There would also be additional increases per-capita in the use of fossil fuels should the rich countries assist the poor countries to achieve the same standard of living and technology. The following are two examples of dynamic studies of energy flows:
"The transition towards renewable energy, physical limits & temporal conditions" by de Castro et al. 2013
"The sower's way: quantifying the narrowing net-energy pathways to a global energy transition" by Sgouridis et.al 2016
Business as usual cannot continue if we are to be successful in mitigating the impact of human induced climate change and reach zero carbon targets by 2050 or earlier. There needs to be an immediate major diversion of investment away from fossil fuels to that of renewable energy. The scale of investment in renewable energy required also means that reductions in the total use of fossil fuels during the transition will not happen unless there are also major reductions in the scale of unnecessary consumption and elimination of all fossil fuel-based investments.
There is a business as usual mentality by many people when it comes to visions of transition. One example is the replacement of fossil fuel cars with electric cars. A total rethink is warranted when it comes to transportation of people and goods. Current electric cars are more of the same in terms of size and weight and there are strong signals that rare earth metals used in battery technology are scarce. Reliance on electric cars for private transport could well prove to be an expensive stop-gap measure. In my opinion, focus and investment should be on public transport rather than private transport and especially on electrifying our national railway network.
The more peer reviewed publications that I read, the more I am coming to the conclusion that we need to reduce our excessive consumption of materials. An increase in recycling will do much to help, but there are limits. 100% recycling of materials is physically and thermodynamically impossible except in ecological systems where dispersal of minerals is an advantage. Human technology require a concentration of minerals and this requires energy. If recycling were 99% efficient and there were no progressive increases in energy costs to do so (there would be in practice), then it would take 100 cycles for originally mined minerals to reduce to 37% of its former magnitude with 63% dissipated and too energy costly to recycle compared to mining. In the meantime continued mining would be necessary to maintain a constant flow of materials and continued mining would become progressively more and energy expensive. Eventually the energy costs of mining would be the same as that of recycling. By that time, if not before, the energy costs of both mining and recycling would be cost prohibitive given that energy would be more urgently needed elsewhere in the economy. I referred to Frank Trentmann's book "The Empire of Things" in a recent email to SCAN members. His book on the history of consumption and his chapter on recycling makes for absorbing reading. We are nowhere near a 99% level of recycling. Even 50% recycling for many products would be an achievement. The days of Thorstein Veblen's "Conspicuous Consumption" are over. My chapter on Excessive Material Consumption is the next chapter that I am writing after identifying key publications on key issues of sustainability.
Preamble over. I will now address your question and comments on my 31 May email to SCAN. On 31 May I posted a modified version of that email on my personal blog below.
1. Which publications?
There are numerous websites and publications on the Internet and books that indicate a rosy transition from fossil fuels to renewable energy. It is these publications that the general public tend to read and believe. To identify these publications, all one needs to do is a Google search.
In a serious study of issues of sustainability, the sources of much more reliable information are contained in peer reviewed international journal publications, and the leading authors are much more difficult to track down when interlinked issues of sustainability cover a diverse range of research outside of one's own area of expertise.
There is currently a growing groundswell in the research community for more sophisticated and in-depth studies of the viability of renewable energy technology.The following publications are an example of the current debate:
"Burden of proof: A comprehensive review of the feasibility of 100% renewable electricity systems" by Heard et al., 2017.
"Response to Burden of proof: A comprehensive review of the feasibility of 100% renewable electricity systems" by Brown et. al. 2018
Previous EROI studies have been found to be deficient in terms of the boundaries of the studies and there is now greater awareness of the need for energy and mass flow studies to establish the scarcity of materials. Davidsson's PhD publication which I referred to with a link in my 31 May personal blog below provides an excellent summary of the problems. I have downloaded the five publications that Davidsson's PhD thesis is based on and I have waded my way through three of them so far. One of these publications spells out in far greater detail the extent of deficiencies in previous EROI studies of wind energy. Only a minority of publications include supply chain consequences in their publications and these are not in-depth studies of potential bottlenecks.
2. Yes, supply chains can be complex. There will undoubtedly be challenges in maintaining technology in a carbon constrained future. That doesn't necessarily mean it's impossible.
My focus is on establishing what these challenges are in advance so that we can prepare for them.
The extent we are currently reliant on a fossil fuel economy is well established, but there are gaps in our knowledge as to the extent we are dependent on computer technology and potential bottlenecks in the supply of minerals required for continued manufacturing of computers and IT networks. Fred Cottrell in his 1955 book "Energy and Society: The Relation Between Energy, Social Change, and Economic Development" refers to an energy field in society which limits the structure and form of human settlements. Recent studies of the same ilk are looking at this issue in terms of the minimum EROI of energy sources required to sustain a particular level of technology. The following is one of those studies:
"Energy, EROI, & the quality of life", by Hall et al, 2014
Computer technology is highly sophisticated and would require a higher EROI compared to that to sustain a society that uses mechanical calculators.
3. Well, no. We don't have time to sit on our hands while academics argue about whether wind turbines will be maintainable or replaceable long term. If we put in wind turbines that last 20 years, it doesn't really matter if we can replace them or not in 20 years. If we can, great. If we can't, at least we've bought ourselves 20 years to power down with lower emissions.
I agree and I have addressed this comment in my preamble.
4. It was always pretty obvious that biofuel was going to compete with food production and wild places. Wind on the other hand (and unlike solar) can co-exist with agriculture. While there are limits and there may be supply chain challenges in future, it is currently one of the few viable sources of low carbon energy.
It wasn't always obvious that biofuel was going to compete with food production. In the 1970s and early 1980s biofuel was regarded as the answer to fossil fuels. Just as well we didn't invest heavily in this technology back then. This decision wasn't due to prudence or forethought. Declining prices in fossil fuels in the 1980s resulted in lack of government interest and resolve to fully transition from fossil fuels to renewable energy of any form.
5. Fundamentally I think we should focus both on reducing energy demand and renewables, particularly wind. I can't see anything fundamental that will be problematic with windpower medium term except the limits of available energy, which we are a long way away from in NZ.
I agree we should focus on reducing energy demand, but we might differ on the emphasis on how we do this. The way I see it is that climate change is a symptom caused by population growth and excessive material consumption. There is little we can do about population growth over the next number of decades due to population momentum (see my chapter on Population Dynamics in my web publication), but a lot we can do about reducing material consumption which currently results in combustion of fossil fuels and greenhouse gas emissions to the atmosphere.
First and foremost, we need to change the current mindset that a growth economy is a superior economy. Government certainly needs to take action to help mitigate the impact of climate change, but it is also action at the community and individual level that is needed. Business as usual cannot and should not continue, but this also applies at the individual level. The big question is will we as individuals take steps to voluntarily reduce our own consumption or will it be necessary for government to intercede and enforce rationing. If greenhouse gas emissions should not decline by the end of 2030 (or earlier) and the impact of climate change consequently accelerates, government should step in and enforce rationing. But it is us who vote in governments, and there will be opposing camps in society as to what steps we should take to mitigate the impact of climate change. This comes back to education and changing the mindset that a growth economy is a superior economy. Our government's recent delivery of its Wellness Budget is a step in the right direction to educate the public that Wellness should be the goal. The next step should be to help educate the public understand that wellness does not necessarily require increases in GDP.
Wind power in New Zealand seems to be a goer, and so too with geothermal. We are blessed living in New Zealand which already generates a high proportion of its electricity using renewable energy sources. I would like to see a subsequent electrification of our national railway network, electric public transport in every town and city, increases in the number of cycleways, and an increase in the power of electric bikes from a limit of 300 watts to 1 Kilowatt to handle the hills of Dunedin. I would also like to see an immediate ban on imports of frivolous SUVs and a progressive tax on imported cars based on their fuel consumption

Modified copy of email to SCAN: The Long-term Viability of Renewable Energy Systems
Over the past week I have processed a number of publications which address the long-term viability of renewable energy systems. Mitigation of human induced climate change requires a reduction to zero emissions of greenhouse gases caused by the combustion of fossil fuels. In the absence of using fossil fuels as an energy source, we will still need to use energy to maintain an acceptable standard of living. Although renewable energy and nuclear energy are feasible alternative energy sources, they are not necessarily viable in the long-term. Production of any technology relies on a web of supply chains which are complex and difficult to unravel. Failure in any one link in any of the supply chains can result in the difference between short-term feasibility of a technology and long-term sustainable viability. It is critical that the long-term sustainable viability of any renewable energy source be clearly established without doubt before investing materials and energy in large scale transitions from fossil fuels to renewable energy. The history of biofuels stand testimony to previous foolhardy expectations based on premature and inadequate energy analyses.
In 2016 Simon Davidsson completed a PhD thesis titled “Natural Resources: Growth Rates and Resource Flows for Low-carbon Systems” which can be downloaded from the Uppsala University website - link here Davidsson’s 50-page PhD thesis is a summary of five of his co-authored and peer reviewed publications published in international refereed journals. These journal publications cover the following topics
·Resource constraints for wind energy.
·Material requirements and availability for deployment of photovoltaics.
·A review of life cycle assessments on wind energy systems.
·Lithium availability and future production outlooks for battery storage.
·Phosphate rock production and depletion related to global food production.
Davidsson’s conclusions in his PhD thesis concur with a number of peer reviewed publications that explicitly address the long-term viability of renewable energy. There are problems and uncertainties of long-term viability which simply cannot and should not be swept under the rug and ignored. Over the next few weeks I will document a number of key publications which address these problems and uncertainties in my web publication In Search of Steady State Revisited.
Regardless of problems and uncertainties, the need to mitigate the impact of human induced climate change still remains. Relying on carbon pricing alone as a way to reduce greenhouse gas emissions will not necessarily bring about expected reductions. I am now leaning towards a per-capita rationing of the purchase of petrol and diesel in New Zealand. This per-capita rationing would decline annually to zero over a number of years. Each year the unused rationing rights could be sold on the market with a percentage of the sale price going to the seller as a reward and a percentage going into a national fund reserved for investment in transitional infrastructure. For me, one highlight of our recent national budget is the allocation of $1 billion towards upgrading KiwiRail. Our railway infrastructure certainly needs to be upgraded and extended, and replacement of wagons would be a sound investment for the future. I am not so keen on replacing our current diesel locomotives with more of the same. A fully electrical railway network is ultimately the sustainable way forward.

Modified copy of email to SCAN: "Trust WHO: The Business of Global Health" documentary
Aljazeera recently screened the documentary "Trust WHO: The Business of Global Health" on its TV channel which I had recorded and viewed last night. I recommend viewing this documentary.
The documentary investigates the lack of independence of the World Health Organisation (WHO) due to influence by corporations and the drug industry etc. which now largely fund WHO. The closing 5 minutes of the documentary includes a damning confirmation of lack of independence by a senior WHO official at question time during a WHO conference.
An especially important part of the documentary for me was its reference to the impact of radiation following the Chernobyl and Fukishima nuclear power station disasters. A number of years ago I saw claims on the Internet that there were only 50 deaths dues to Chernobyl which, at the time, didn't sound right to me. WHO had/has perpetuated this misinformation on its website. This documentary sets the record straight.
Usually Aljazeera screened documentaries can be viewed from its website, but not in this case. The documentary can be viewed on a paid basis (rental or buy) from a number of organisations. I have opted for a buy option of US $10 (2.5 GB MP4) from Vimeo to add to my collections of videos on issues of sustainability.

Steve Keen and the Role of Energy in Production
Professor Steve Keen is a renegade economist who is highly critical of neoclassical economics as being inconsistent, unscientific, and empirically unsupported. Steve Keen would be regarded as an anathema to most current economic departments. His book “Debunking Economics: The Naked Emperor Dethroned?”, revised and expanded 2nd edition 2011 is well worthwhile reading.
Steve Keen's major contribution to economics so far has been on mathematical modelling and simulation of financial instability based on Hyman Minsky's financial instability hypothesis. He designed the simulation software called "Minsky" to help him do so.
Steve Keen has addressed the role of energy in production for a number of years and I highly recommend viewing the following YouTube videos of two of his lectures:
'Value theory, thermodynamics and dialectics' - YouTube link here
‘The Role of Energy in Production (with discussion)’ -YouTube link here
For a list of Steve Keen’s videos – Link here
For a list of Steve Keen’s lectures – Link here
One of Steve Keen’s recent international refereed journal publications is “A Note on the Role of Energy in Production”, 2019 co-authored with Robert Ayres and Russell Standish.

Modified copy of email to SCAN: Prevarication and back-pedalling by United Nations Secretary General in interview on Climate Change
I recommend viewing Monday night's Q&A with Jack Tame interviewing the United Nations Secretary General (UNSG), Antonio Guterres, on climate change and, in particular, New Zealand's forthcoming Zero Carbon Amendment Bill. If you missed it, then you can see it on TV On Demand 30 minutes in: link here
At the start of the interview the UNSG came on strong about the lack of action and commitment by world governments, but prevaricated and back-pedalled when Jack Tame asked some hard questions on his response to New Zealand's commitment. For me, the UNSG came across as being of the same cloth that he was critical of. He wants to be seen doing his job as UNSG, but when it comes to the crunch, he lacks the grit to truly get the message across. Diplomacy be damned. His role as UNSG is to provide clear directions as to what governments should do to mitigate the impact of climate change. It is a shame that our former New Zealand Prime Minister, Helen Clark, missed out on being elected UNSG. Congratulations to Jack Tame for asking the hard questions and shame on Antonio Guterres for not giving straight answers, especially given his opening statements.

Modified copy of email to SCAN: Netherland Government Report - Growing within Limits
In the first interview below, Dennis Meadows refers to a report by a Dutch Environmental Agency. I have tracked down this report - Growing within Limits published by the Netherlands Environmental Assessment Agency, 2009. Download link here
The report was presented at the conference celebrating the 40th anniversary of the Club of Rome,
in October 2009, in Amsterdam.
The front summary of the report states:
“The risks of the ‘Business-as-usual’ are now well understood and could severely threaten the sustainability of human society.
…What is the problem? Human society will face severe problems when global bio-physical trends in climate change and biodiversity loss continue. Since the publication of “The Limits to Growth’ for the Club of Rome in 1972, it has become increasingly clear that the current trends in the consumption of fossil fuel and other resources, use of land, and pressure on the Earth’s capacity to deal with pollution lead to serious environmental risks. In numerous global environmental assessments published since 1972, more detailed analyses have been made in terms of analysis of specific environmental problems and their magnitude. These studies also show that should historic trends continue in the coming decades, then the world will run into an increasing range of environmental and social tensions. Two top priorities can be derived:
1. ensuring a sustainable energy supply while avoiding climate change
2. preventing terrestrial biodiversity losses while ensuring food security - also in light of possible threats to human development, including poverty."
The above government report acknowledges and accepts there are limits to growth. Far too many government reports on the mitigation of climate change are based on an underlying premise that business as usual can and should continue as much as possible. The subsequent goal of such reports is to continue maximising growth in GDP. The goal should be to maximise wellbeing within ecological constraints rather than maximise GDP which is a widely acknowledged inadequate indicator of wellbeing. Vivid Economics publications commissioned by governments are prime examples of publications which essentialy promote economic growth in GDP. These reports either ignore or are unaware that climate change is a symptom and result of excessive growth in population and material consumption which, together, now exceeds the carrying capacity of our planet Earth.
Successful mitigation of climate change depends on first acknowledging and accepting that growth in population and material consumption needs to be curbed and then adopting appropriate policies. If a person has dislocated his shoulder, then treating the symptom of pain with pain killers will not alone discontinue the pain. The cause and source of the pain needs to be addressed in order to fully cure the patient.

Recommended Book by Vaclav Smil
I highly recommend Vaclav Smil's 2017 book Energy & Civilization: A History (609 pages). Amazon.com link here
Growth simply cannot continue. The only other alternatives are a decline to extinction or a form of steady state. In my web publication In Search of Steady State Revisited that I am currently writing, I assume that humankind will survive the oncoming transition from a growth society to that of steady state. What is uncertain is the form of transition. It is highly unlikely that a transition from growth to steady state will be smooth without disruption. This is because the world population will continue to increase for a number of decades yet due to population momentum, albeit at a declining rate of growth, while at the same time we will be confronting the impact of the peaking of conventional oil and continued impacts of climate change. Zero carbon cannot and will not be achieved overnight.
One of the sections in my web publication compares the attributes of a growth society to that of a steady state society (link here). I suggest that the primary directions of change from growth to steady state are already well known. The attribute table is largely based on the same table in my 1978 sub-thesis In Search of Steady State which summarised research back in the 1970s. What is uncertain is the magnitude of change.
The magnitude of change and the type of steady state that future generations will be able to enjoy depends on the supply chains that are necessary to support a steady state society. Forget monetary estimates. They are useless within the context of establishing what is possible. It is ultimately stocks of energy and matter, flows of energy and matter, and the laws of thermodynamics and nature which will determine what is not only feasible, but also viable. True sustainability is the long-run continuation of supply chains, and the rate of flow of supply chains can be constrained by bottlenecks in just only one link of one chain.
Fully tracking the full extent of supply chains and identifying bottlenecks in order to establish what is possible is extremely complex and difficult. These estimates are constantly undergoing revision as the boundaries of systems are expanded with each more sophisticated study. Nonetheless, back-of-the-envelope estimates can be illuminating, for example, David Mackay provides sobering estimates in his book Sustainable Energy Without the Hot Air (Amazon.com link here).
This brings me back to Vaclav Smil's book Energy & Civilization: A History. His chapter on food production and fertilisers describes the percentage of nitrogen in organic and human waste-based fertilisers required to replenish necessary nutrients in the soil compared to that provided by artificial fertilisers. The enormous difference has substantial implications for long-term food production in a steady state economy. Research by Charles Hall etc. etc. on the EROI of fossil fuels and renewables are also sobering over and above the back-of-the-envelope estimates by David Mackay.
And what do I mean by sobering? The more research that comes out from peer reviewed international refereed journals, the more there are indications that any transition from growth to steady state will be disruptive in that business as usual cannot and will not continue. Transition will involve changes and sacrifices regardless of whether they be willing or not. Peer reviewed research indicates that the longer we delay in taking action to transition from fossil fuels to renewables and the longer we attempt to continue growth and business as usual, the greater will be future disruptions.
Whatever transpires over the next number of decades, localisation and ensuring food production and water supply security is the way to go.

Modified copy of email to SCAN: The Emissions Trap
I have downloaded a recent key publication The Energy Emissions Trap by Martin Sers & Peter Victor, 2018. The abstract states:
"The requirement to reduce emissions to avoid potentially dangerous climate change implies a dilemma for societies heavily dependent on fossil fuels. Reducing emissions will necessitate the transition from relatively high EROI dispatchable fossil fuels to a combination of relatively low EROI intermittent renewables and geographically limited non-intermittent renewables. As renewable capacity requires energy to construct there is an initial fossil fuel cost to creating new renewable capacity. An insufficiently rapid transition to renewables will imply a scenario in which it is impossible to avoid either transgressing emissions ceilings or facing energy shortages; we term this the energy-emissions trap."
The publication concludes:
"Examining the net energy trajectories for scenarios three and four in Fig. 8, we see a key result of the EETRAP model: the long run consequence of transitioning to renewables with life-cycle energy returns at sufficient pace to avoid transgressing cumulative emissions limits is a decline in the net energy available to society. The magnitude of this decline may be large should the EROI of intermittent renewables decline with increasing share of energy production. ...
...it is necessary to note that many of the model assumptions are still rather optimistic.
... EETRAP models a world without construction permits, delays, planning, and political setbacks. Realistically, there is a substantial amount of planning and time necessary to construct and install new renewable capacity which is not reflected in the present modelling work.
Therefore, we note that even under relatively ideal conditions facilitating a successful energy transition in the context of declining intermittent renewable EROI may necessitate a large-scale redirection of society's resources to the energy sector. The results of this modelling experiment indicate that it is still possible to transition to renewables, even in the case of declining EROI, though maintaining steady economic growth in such a scenario may not be feasible. However, as economic growth drives increases in emissions, such continued growth may be neither feasible nor desirable if societies takes seriously the goal of escaping the energy-emissions trap."
The conclusions of the above publication come as no surprise. What I have found to be more disturbing is information contained in Jeremy Leggett’s latest slide show (115 slides). The sources and citations of Jeremy Leggett's slides are included in the PowerPoint PPT file which can be downloaded here. This particular series of slides includes data on the erosion of democracy over time in various countries and the escalation of surveillance and robotization of warmongering.

Modified copy of email to SCAN: Deep Adaptation: A Map for Navigating Climate Tragedy
Thank you for drawing attention to Jem Bendell's publication. I have now read Jem Bendell's publication Deep Adaptation: A Map for Navigating Climate Tragedy and I have viewed his Deep Adaptation presentation on YouTube which I recommend viewing. Jem Bendell is a good presenter and what he has to say cannot and should not be too easily dismissed. I have included his publication and video on my website.
No, I didn’t find Jem Bendell's publication or his YouTube presentation to be disturbing because I have already come to more or less the same conclusions. I have processed many key peer-reviewed publications which have inched me towards a conclusion that some form of collapse of civilisation as we now know it is possible before 2050. Preparation for the possibility of a collapse is necessary for our continued survival. I am optimistic there will not be a total collapse of civilisation, however my optimism might prove to be without foundation.
Jem Bendell did a poll on the audience's emotional response to his presentation which would have been shocking bad news for many in the audience. For me it was gratifying that the emotional response of a majority of the audience included motivation.
The possibility of a social collapse is very real and yes, I agree that a global social collapse would certainly halt carbon emissions and perhaps, if not already too late, would protect the other species with which we share our planet. Acceptance of the possibility of collapse and subsequent preparation and deep adaptation could be a key to humankind's continued survival. Any long-term survival will require adopting the fundamentals of steady state.

Modified copy of email to SCAN: FEASTA Theory of Change chart on How to get to where you want to
The top row in the FEASTA Theory of Change chart sets out the issues which need to be addressed in order to attain “The Ultimate Goal of a vibrant, commons-based and stable global economy within a resilient and healthy global ecosystem.” These issues include:
Capping of global carbon,
Provision of a universal basic income,
Use of resource-based taxation Including land value tax,
Improved measurements of progress,
and wide spread adoption of agroecology and soil protection measures.
The title of our group SCAN - Seniors Climate Action Network -suggests that our group is entirely focused on only capping global carbon in order to mitigate the impact of climate change which threatens our well-being in the future. However, the above issues in addition to capping global carbon are also at the heart of our group because if they are not addressed, then they will also also threaten our future well-being and hinder, if not delay, mitigation of climate change.
The inclusion of a land value tax in the above chart is of note and especial interest to me. This form of taxation is abhorrent to the one percenters, or the ten percenters for that matter, who own an obscene proportion of the total wealth in any country. A land value tax and other forms of taxation and policies can help promote sustainability of our building stock and reduce unnecessary demolition. I addressed these additional forms of taxation and policies in a conference paper titled Policies and Strategies to Enhance Social Benefits Due to Private Rehabilitation of Buildings.

Modified copy of email to SCAN: Envisaging a Lifeboat Economy
When I first saw the title of the article - Envisaging a Lifeboat Economy - I immediately thought the article would be in the same vein as the section called Living on a Lifeboat by Garrett Hardin in the 1977 book Managing the Commons. Garrett Hardin's article outlined a thesis of lifeboat ethics, a scenario where a lifeboat cannot and should not carry more people beyond its floatation capacity otherwise the lifeboat will overturn and the occupants will be tossed into the ocean alongside others grappling to get into the lifeboat. If the lifeboat occupants don't prevent more people from getting into the lifeboat, then no one is saved.
As an aside, Garret Hardin's 1970s thesis of the inevitability of The Tragedy of the Commons was countered and overturned by Elinor Ostrom, recipient of the Nobel Memorial Prize in Economics. In 1990 Elinor Ostrum published a very readable book on her research called Governing the Commons: The Evolution of Institutions for Collective Action. In 1978 I followed many others and included Garret Hardin's thesis of inevitability in my sub-thesis In Search of Steady State. This was a mistake that I now regret. Back then I hadn’t included counter-arguments based on evidence - in hindsight there were none in the 1970s - and drawn my own conclusions.
When I read the article Envisaging a Lifeboat Economy, I was uplifted. Yes, some of what was said was grim reading - Brian Davy doesn't pull any punches - but nonetheless cold jolts of reality can be reassuring because it is better to know what can potentially threaten one's safety and survival so that one can be better prepared and more resilient. A question arises - are the threats outlined in the article real or is Bryan Davey exaggerating and merely crying out wolf? From what I have observed and read, the threats he mentions are very real. His article includes positive actions of preparation which are familiar and similar to those advocated in the 1970s.
Brian Davey has also written the 488 page book called Credo, Economic Beliefs in a World of Crisis which I highly recommend. A copy can be downloaded for free (5 MB) from the Brian Davey’s website here

Modified copy of email to SCAN: Could the future be rural?
Thanks for the link to the publication The Future is Rural: Food System Adaptations to the Greater Simplification by Jason Bradford.
At long last a serious report which echoes the conclusion reached by a group of final year architectural students and included in my 1978 sub-thesis In Search of Steady State. Some 40 years later I still have strong reservations about whether super cities can ever be sustainable. Densification has been possible due to production having a surplus using energy-slaves with a high EROI. The EROI of renewables are a lot less than that of fossil fuels before 1970. Future surpluses under renewable energy will be more limited. Population will continue to grow for many more decades. Growth of towns rather than cities should be encouraged rather than be stifled.

Modified copy of email to SCAN: 2016 claim by Nicholas Stern that climate change models are overly optimistic
I agree the title Current Climate Models are Grossly Misleading that Nicholas Stern chose to use in his 2016 Comment in Nature Online was unfortunate. Unless one reads the Comment as well as the title, it is far too easy for anyone with a predisposition for knee-jerk reactions to assume that climate change is over-hyped. The article in fact states exactly the opposite.
I don't agree with Nicholas Stern's "green growth" approach - sustained economic growth and decoupling of resource use and economic growth are both impossible in the long run. Perhaps Nicholas Stern hopes that economic growth is possible in the short term to alleviate poverty in the less developed countries. However, I do agree entirely with his above Comment about climate change modelling and his recommendation for greater use of stochastic computable general equilibrium (DSGE) models and agent-based models (ABMs).
Steve Keen is scathing that most neoliberal economists do not make use of DSGE models. His Minsky models are DSGE models which also include the banking sector. The software package called AnyLogic provides for both DSGE and ABM modelling. A free Personal Edition can be downloaded from here
Sgouris Sgouridis, Denes Csala, and Ugo Bardi used Anylogic to model pathways to a global energy transition in 2016. Their peer reviewed publication is called The sower’s way: quantifying the narrowing net-energy pathways to a global energy transition. When Nicholas Stern wrote his Comment in Nature in 2016, researchers of climate change and the need for transition from fossil fuels to renewable energy had been using DSGE models for a number of years.
I agree that "too often economic arguments are embedded in the status quo economic environment" and that "many writers talk about what we can afford to do rather that what we cannot afford not to do." Nicholas Stern states in his Comment that "Economists, in particular, need more help from scientists and engineers to devise models that provide better guidance about what will happen if we succeed or if we fail." Those scientists must include physicists and ecologists. Too many economists have a narrow and blinkered viewpoint of what is important. In times of war, the government deficit pales into insignificance - there is no hesitation to create debt to finance investment in war machines. Governments instead of private banks can create money when necessary for critical investment without any interest charge or, for that matter, need to repay the debt. A debt to oneself never needs to be paid back.
I largely agree with the following comment by a SCAN member about technological development except for the reference about Alice Friedemann:
“I am not one who believes in assuming that technological advancement will necessarily provide the solution but equally I don't buy into the rather close-down discussions that are put forward by people such as Alice Friedemann. She certainly does very useful work but I think is too quick to dismiss (or perhaps just doesn't address) the role of possible advancements in technology, and the potential changes in society.”
For me, Alice Friedemann plays an important role as devil's advocate. Whenever I follow up her comments about what is impossible by reviewing the literature, I find that she is usually right on the mark. It comes down to what is feasible and what is viable. For example, electric planes and electric trucks are feasible - have a look on YouTube for electric planes and trucks - but are they viable in large scale and in the long run? Energy and mineral analysis studies of critical supply chains need to be made to establish and confirm what is viable in the long run. A sustainable horizon does not stop at 2050 or 2100.
I also agree that in the long run “a better regime needs to be implemented if the human race is to survive.” I have just finished reading a book called Churchill & Orwell: The Fight For Freedom, by Thomas E. Ricks, 2017. In the back cover description of the book "Both Churchill and Orwell had the vision and courage to campaign tirelessly against the totalitarian threat from both the left and the right". Not having experienced the hardships before and during WWII, the book is a reminder to me that there are real risks of not only future negative impacts of climate change and peaking of oil and minerals for civilisation to confront, but there are also real risks of an erosion of democracy in the future. As a number of people have been saying for quite a while, it is the politics and not the science that will largely determine our future with regards to the mitigation of climate change. Unlike the early 1980s when there were protests against the Springboks touring New Zealand and many New Zealanders claimed that politics should be kept out of sports, politics is very definitely part and parcel of our attempts to mitigate the impact of climate change.

Modified copy of email to SCAN: Patreon support of Steve Keen and Russell Standish
For those who have a keen interest in economics which is relevant to the real world, I recommend following Professor Steve Keen who wrote the book Debunking Economics, 2011. Steve Keen is currently working on injecting energy into economic theory and dynamic economic models. He has also designed a dynamic systems software called Minsky which includes Godfrey Tables so that the banking system (creation of money) can be included in dynamic models of the economy. Russell Standish has been working on the Minsky software coding.
I have been a patron of Steve Keen on Patreon for sometime now which gives me access to his podcasts. These podcasts are highly entertaining and informative. Becoming a patron will give access to all podcasts. A few weeks ago I responded to Steve Keen's call to support further coding of Minsky and I became a patron of Russell Standish on Patreon
There are very few people or organisations that I make monthly donations to. My donations which support Steve Keen and Russell Standish will help bring about a much needed transition away from the current neoliberal mainstream economics stranglehold on world politics and decision-making back to politics and decision-making based on reality.

Copy of email to SCAN: Achieving more with less
The UNEP 2016 document Global material flows and resources productivity in my previous email states the following:
"Population has continued to contribute to rising material demand but not to the same extent as rising per capita income and the emergence of a new middle class in developing countries. …The material intensity of the world economy has been increasing for the past decade, driven by the great acceleration that has occurred since the year 2000.
...Production has shifted from very material-efficient countries to countries that have low material efficiency, resulting in an overall decline in material efficiency. ...global material productivity has declined since about the year 2000 and the global economy now needs more materials per unit of GDP than it did at the turn of the century. What may seem counter-intuitive has been caused by a large shift of economic activity from very material-efficient economies such as Japan, the Republic of Korea and Europe to the much less material-efficient economies of China, India and Southeast Asia.
This has resulted in growing environmental pressure per unit of economic activity and works against the hypothesis of decoupling – achieving more with less – which is so important to the success of global sustainability."
Construction of infrastructure and buildings and sustaining that capital requires the use of materials by the tonnage. This is the case in China where an enormous expansion of infrastructure and buildings has taken place in recent decades. In a study of the New Zealand housing stock in 2004 I used a dynamic simulation model to compare the benefit-cost ratio of sustaining a constantly growing housing stock and a stationary housing stock which stays the same size (download here). I set the growth housing stock to expand at a constant rate of 1.5% per year, the average expansion rate of the New Zealand housing stock over the previous decade which, if continued, would result a doubling in the size of the housing stock every 48 years. The benefits of the housing stock were measured in dwelling service years adjusted for depreciation and the costs were measured in construction units, the resources required to build, refurbish, maintain and replace each dwelling. These units allow comparison with housing stocks in other countries. The benefits of dwelling service years and the costs of construction units can be converted into dollar terms by multiplying by the price of each which respectively give the average yearly rent for services provided by the housing stock per dwelling (excluding the services of land) and the average annual dollar costs of sustaining the housing stock per dwelling.
I estimated that the stationary housing stock would provide a 32.4% higher benefit-cost ratio than the expanding housing stock. The reason why is because the full benefits of investing in the construction of a new dwelling are not immediately realised in the first year after construction. Instead, these benefits are realised over the full service life of each dwelling. But each year more dwellings than the previous year not only replace dwellings that depart from the housing stock in that year, but also add to the size of the housing stock. Full realisation of the benefits of each dwelling recedes into the distant future. With a stationary housing stock, new dwellings replace old dwellings and at any one year the full benefits of the dwellings are enjoyed. This is because the composition of the entire housing stock by age remains the same from year to year and the number of dwellings within each cohort by age within the housing stock mirror the entire history of a single cohort of dwellings which are constructed each year to replace older dwellings.
The same dynamics apply for all expanding and stationary capital stocks and also in Nature. A child while growing rapidly requires more Calories per kilogram of body weight than an adult. Likewise, plants and trees require more nutrients while growing to full maturity. Growth of any form requires more resources than a stationary or climax state. Achieving more with less is impossible if the target is to achieve more.

Modified copy of email to SCAN: Decoupling use of resources from the economy
Some time ago I downloaded the following document: Global material flows and resources productivity, UNEP 2016. While recently writing about population dynamics, I have referred back to this document and it has occurred to me that there are some claims in circulation that countries can and will decouple material use and related environmental impacts from the economy. The above United Nations Environmental Programme (UNEP) document sets the record straight. The document concludes there is a need to decouple material use and environmental impacts from the economy, but does not provide solutions. No doubt efficiencies in the use of resources can be improved, wastage can be avoided, and greater use of recycling can be implemented. However, there are physical and thermodynamic limits to the extent of decoupling. The ability to sufficiently decouple does not automatically follow from the need to decouple. The following extracts are from the above publication:
"Consumption has been driving material use
Globally growth in per capita income and consumption has been the strongest driver of growth in material use, even more important than population growth in recent decades, especially since 2000. Population has continued to contribute to rising material demand but not to the same extent as rising per capita income and the emergence of a new middle class in developing countries. Material efficiency mitigated some of the growth of material use driven by growing population and world economy between 1970 and 1990. Since 1990, there has not been much improvement in global material efficiency, which actually started to decline around 2000.
The material intensity of the global economy has increased
The material intensity of the world economy has been increasing for the past decade, driven by the great acceleration that has occurred since the year 2000. Production has shifted from very material-efficient countries to countries that have low material efficiency, resulting in an overall decline in material efficiency. ...global material productivity has declined since about the year 2000 and the global economy now needs more materials per unit of GDP than it did at the turn of the century. What may seem counter-intuitive has been caused by a large shift of economic activity from very material-efficient economies such as Japan, the Republic of Korea and Europe to the much less material-efficient economies of China, India and Southeast Asia.
This has resulted in growing environmental pressure per unit of economic activity and works against the hypothesis of decoupling – achieving more with less – which is so important to the success of global sustainability.
A new indicator, material footprint of consumption, shows the true impact of wealthy economies on global material use
This report adopts a new indicator for the material footprint of consumption, which reports the amounts of materials that are required for final demand (consumption and capital investment) in a country or region. This indicator is a good proxy for the material standard of living. The current global systems of production result in a material footprint of Europe’s consumption of around 20 tonnes per capita and a material footprint of North America’s consumption of around 25 tonnes per capita. ...
...The material footprint indicator allows, differently from measures of material extraction and direct material use, the establishment of a landing point for industrial material use. It may well be that industrial metabolism stabilizes at between 20 and 30 tonnes per capita for the current ways in which we build houses and transport infrastructure, how we organize mobility, and deliver manufactured goods, food and energy. Given the fact that the global economy, at today’s level of resource use, is already surpassing some environmental thresholds or planetary boundaries, this shows that the level of well-being achieved in wealthy industrial countries cannot be generalized globally based on the same system of production and consumption. Large improvements in decoupling are needed to service the needs and aspirations of a growing global population in an inclusive way.
Large gaps in material standard of living persist
There is still a large gap in the average material standard of living and resulting material footprint between North America and Europe and all other world regions. Annual per capita material footprint for Asia and the Pacific, Latin America and the Caribbean and West Asia is between 9 and 10 tonnes, or half the per capita material footprint of Europe. The EECCA region is following with 7.5 tonnes per capita and Africa, on average, has a material footprint of below 3 tonnes per capita. ...
... The average material footprint of countries with medium levels of human development has grown slowly over the past two decades, reaching 5 tonnes per capita, while material footprint in low HDI countries has been stagnant for the past two decades at 2.5 tonnes per capita. The richest countries consume on average 10 times as many materials as the poorest countries, and twice the world average, which demonstrates very unequal distribution of materials to support the standard of living shows that the low income group of countries will require increasing quantities of materials, per capita, to achieve the sustainable development outcomes the global community aims for.
A comprehensive database for global material flows
This report provides a comprehensive understanding of linkages between the world economy, population and material use over four decades (1970–2010) based on a new and authoritative database of global material extraction and a revised database for materials trade. It uses a standard set of material flow accounting indicators as well as new indicators. The data and indicators presented in this report will allow countries and regions to monitor their progress in achieving greater material efficiency through well-designed national policies and regional initiatives. ...
...In this report, the use of materials – society’s metabolism – is interpreted as an environmental pressure. Material use is also closely related to other pressure indicators including waste flows, energy use and carbon emissions, land use and water use. When material use grows, ceteris paribus also the other pressure indicators will increase. Material use is also used as a proxy for environmental impacts that will occur across the whole life cycle of material use from extraction, transformation and consumption to disposal. When material use increases, the environmental, social and economic impacts of material use also see a commensurate rise. Rising material use will result in climate change, higher levels of acidification and eutrophication of soils and water bodies, increased biodiversity loss, more soil erosion and increasing amounts of waste and air pollution. It will also have negative impacts on human health and quality of life. It will ultimately lead to the depletion of certain natural resources and will cause supply shortages for critical materials in the short and medium terms.
While many resources will still be abundantly available over the medium and long terms, pollution and ecosystem degradation and a changing climate will dominate the political debate around using materials more effectively and efficiently. Fast-expanding demand for materials will, however, require very large investments into new extraction and supply infrastructure and will contribute to local conflict over alternative uses of land, water, energy and materials. Such conflict is already pronounced in the energy sector where mining competes with agriculture and urban development in many places.
Decoupling is the imperative of modern environmental policy
Decoupling of material use and related environmental impacts from economic growth is a strategy that will be instrumental for ensuring future human well-being based on much lower material throughput. Many regions and countries have embarked on a strategy to substantially increase the material efficiency of their economies and to reduce the overall level of material use. Many countries and regions, including the European Union, Japan and China among others, now have high-level policy frameworks and laws that support resource efficiency and guide investments into green sectors of the economy supported by sustainable consumption and production practices."
Ibrahim Thiaw, United Nations Assistant-Secretary-General and UNEP Deputy Executive Director, wrote the following Foreword to the above publication:
"Natural resources provide the foundation of our lives on Earth. Water, soil, energy, minerals and metals underpin our standards of living. They feed and shelter us, and provide for our material needs throughout our lives.
Yet pressures on these natural resources are mounting. A growing population and heightened world economic demand in the past half century are rapidly depleting these vital resources, inflicting great harm on the natural environment and human health. In our ever-more globalized economy, sustainable management of natural resources will become increasingly important.
When the world’s nations approved the Sustainable Development Goals in 2015, they set out a path towards solving some of these great challenges. These ambitious goals aim to eradicate poverty and sustain economic growth, while maintaining the natural resource base and planetary ecosystems for future generations. Turning the goals into reality will require concerted action by the entire world, developed and developing countries alike. For these reasons, we must better understand where and how natural resources are used. ..."
Ibrahim Thiaw's reference to sustaining economic growth is an oxymoron. Energy Skeptic, Alice Friedemann, correctly points out in her blog on the above publication that "The UN doesn’t flat out state there are limits to growth, though they come close when they point out there’s not enough stuff in the world to raise the standard of living for everyone and we appear to be on an unsustainable trajectory (page 5)".
Many researchers in New Zealand government departments are well aware that sustained economic growth is an impossibility just like the authors of the above report who either work for or are commissioned by the United Nations. This awareness also comes out loud and clear in New Zealand government research reports. But too frequently politicians stifle or water down the conclusions of hard evidence-based reports on the environment and the economy. It is politics which will ultimately determine the future course of mitigating climate change and not the science. In a truly democratic society, politicians with integrity vote according to the wishes of their electorate. Politicians with integrity are not swayed by self-serving lobby groups which disregard the public good and politicians with integrity are immune to being influenced by organisations and businesses which make political party donations in expectation of political favours. The United States electoral system is a prime example of an erosion of democracy. In the United States the citizens are also subject to deliberate campaigns of misinformation and legitimate news is accused by its president as being “Fake News”. Our New Zealand citizens needs to be well educated on issues of sustainability and we need to be watchdogs and maintain constant vigilance against similar erosions of democracy and manipulation of news.

Jorgen Randers’s claim that the world population will never reach beyond 9 billion people.
Jorgen Randers claims that the world population will never reach beyond 9 billion people in his 2014 TEDtalk on YouTube. His projection of the world population which is based on an extrapolation of a continued decline in the world total fertility is both dubious and flawed. I agree that the world population might never reach 9 billion people, but I doubt this would be due entirely to a decline in total fertility alone.
Jorgen Randers is not a demographer with expertise in the field of human population dynamics and his projection runs counter to that of world leading demographers. All projections of population growth are based on a number of tacit and explicit assumptions which might never eventuate. We simply cannot predict what the future holds in store for us. Nonetheless, some assumptions are more realistic than others. Before taking any projection seriously, I would first examine the underlying assumptions. This has not been possible from the above TEDtalk.
The TEDtalk on YouTube is dated 2014, but the talk might have been delivered at an earlier date. There is always a lag before global statistics become available. In 2019 the latest United Nations and World Bank statistics on total fertility are that of 2016 which is a 3-year lag.
Jorgen Randers's graphs are shaded grey on the left-hand side of 2008 and projects forward from that year. The sharp decrease in total fertility at the year 2008 does not tally with global population statistics that would have been available in 2005. There was no sharp decrease in total fertility from 2008 onwards. Yes, total fertility has declined substantially the last 40 years in high-income, middle income, and low-income countries, but since 1995 the decline has slowed down globally and especially in the middle-income countries which have by far the largest population of the three income groups. When graphing the rate of change in total fertility, the trend of a slowdown in the global and middle-income countries decline in fertility since 1993 is very clear. There is no justification for assuming, or whatever, that there was a sharp decrease in total fertility in 2008. Jorgen Randers has extrapolated a non-existent sharp decrease in total fertility into the future. Instead, he should have extrapolated the rate of change in total fertility.
Total fertility tends to drop with prosperity. Prosperity enables better medical care, nutrition, education, and the possibility of a welfare state to care for the elderly. The gap between the prosperity of high-income countries and that of middle-income and low-income countries has increased over the last 40 years.
Prosperity is dependent on access to and use of high-grade energy whether that be fossil fuels or renewable energy. Sustained declines in total fertility are dependent on continued access to and use of high-grade energy. If middle-income and low-income countries do not have their own fossil fuel resources, then they have to bid against high-income countries for those resources on the global market. Increases in the price of fossil fuels will impact more so on the lower-income countries than the high-income countries which are better able to absorb and adapt to such increases.
It is a brave assumption that the prosperity of the middle-income and low-income countries will continue to improve at a rate sufficient to influence total fertility to the extent that the world population never exceeds 9 billion people based on reductions in total fertility alone. It is unlikely that a sufficient global rate of production of fossil fuels is possible to enable a substantially higher per-capita use of fossil fuels in the middle-income and low-income countries, especially when the populations of these countries continue to grow.
If there is to be greater prosperity in the lower-income countries with subsequent reductions in total fertility, a global transition from fossil fuels to renewable energy, and global reductions in greenhouse gas emissions, then the high-income countries will need to divert their use of fossil fuels into renewable energy away from consumption and assist lower-income countries to raise their standard of living while, at the same time, decrease their total use of fossil fuels. Development assistance to lower-income countries should not follow the same course of development as that of the high-income countries which is not sustainable. Further development of lower-income countries should be truly sustainable by using renewable energy and appropriate low-energy use technology. In the meantime, while all countries continue to use fossil fuels, subsequent CO2 emissions add to the total stock of greenhouse gases in the atmosphere which, in turn, exacerbate climate change which, in turn, impacts on global food production. An FAO report titled The potential effects of climate change on world food production and security concludes:
"Although some countries in the temperate zone may reap some benefits from climate change, many countries in the tropical and subtropical zones appear to be more vulnerable. Particular hazards are the possibly increased flooding of low-lying areas, the increased frequency and severity of droughts in semi-arid areas, and potential decreases in attainable crop yields. It happens that the latter countries tend to be the poorest and the least able to make the necessary economic adjustments. Much of the expected change in global climate is due to the past and present activities of the industrial countries; so it is their responsibility to commit themselves to, and to play an active role in, a comprehensive international effort to prepare for the likely consequences."
Jorgen Randers's claim that the world population will never reach beyond 9 billion people might prove to be correct, but not necessarily for the reasons he gives in his TEDtalk.

Copy of email to SCAN: Extinction Rebellion’s Petition
I agree with Pat’s recent article emailed to SCAN members that the role and focus of SCAN has been (is) to raise awareness, bring about hope, share the good news of what is already happening, lobby local and central government, and support the global movement towards resilient communities. I also agree with Pat that SCAN acknowledges and supports those who seek an end to fossil fuels and that there are a number of ways to achieve this.
I have reservations about Extinction Rebellion’s petition which states “We, the undersigned, demand that the Government enacts legally-binding measures to reduce greenhouse gas emissions to net zero by 2025.” The heading of the petition is “Climate disruption requires the declaration of a state of emergency”.
I have mixed feelings about the petition. I fully support Extinction Rebellion’s appeal for immediate action and I am sympathetic to its Declaration of Rebellion that “We hereby declare the bonds of the social contract to be null and void, which the Government has rendered invalid by its continuing failure to act appropriately.” However, the social contract is not just between citizen and government but is also between citizen and citizen. It is the past and current actions of citizens which have contributed to and continue to exacerbate the impact of climate change, and it is the actions of citizens which will mitigate the impact.
Extinction Rebellion’s Our Demands state "The Government must tell the truth about the climate and wider ecological emergency, reverse inconsistent policies and work alongside the media to communicate with citizens." The petition's Open Letter states “Our government needs to tell the truth about this unprecedented challenge to our well-being.” Does the current New Zealand government hide the truth about climate change? The previous New Zealand government delayed action (see film about climate change politics in New Zealand), but the current New Zealand government has not and does not hide the truth about climate change.
The truth about climate change has been out there for decades, and yet the majority of citizens around the world has failed to take on board this truth and act accordingly. Campaigns of deliberate misinformation has held back the truth, and acknowledgement by any government as to the truth about climate change can help counter this misinformation. The very fact that our current New Zealand government is in the process and about to pass the Zero Carbon Act is an acknowledgement of the truth about climate change and the need for action.
A primary issue is about immediacy and scale of action. I agree with Extinction Rebellion that full-scale action is required now and not later. I have stated so in my submissions to government, Dunedin City Council, and Regional Council, and many times in my personal blogs on my website. So why do I still have reservations about signing Extinction Rebellion’s above petition. It is the call for a declaration of a state of emergency that I baulk at. It is not just the New Zealand Government that needs to act immediately with full scale measures, but it is also New Zealand citizens. I believe that cooperation and trust between citizens and government and between citizens and citizens will be more successful in mitigating the impact of climate change than coercion by government.
Instead of signing a petition that calls for a state of emergency, I would rather sign a petition for the New Zealand Government to immediately set up and promote a national education campaign to bring all New Zealanders up to speed with the need for action and support of change. SCAN and similar groups are already doing this. Government endorsement of these groups will help.

Modified Copy of email to SCAN: Benefits, Disbenefits, Feasibility and Viability of Technology
Your email comments about the recent commercial for-hire green scooters in Dunedin and technology pressed a few buttons for me. On Tuesday I parked my 670 cc Suzuki Alto up the hill by Moana Pool on Tuesday before our SCAN meeting. (I would seriously consider buying a two-seater lightweight electric vehicle if one were available in New Zealand. One overseas example is the PEBL).
While walking back up Stuart Street to my car after our meeting, I came across a person with a green scooter on the footpath waiting at the next traffic lights intersection. We got talking before the lights turned green for us - we talked about the effort he needed to get to the traffic lights - and when the lights turned green he continued up Stuart Street with much greater speed than my walking pace by periodically assisting his scooter with a backward push with one leg. The speed he was able to scooter up the steep hill of Stuart Street without undue effort impressed me.
In the 1960s I used to bike from Bayfield High School to Moana Pool each afternoon after school. It took much less effort to push my bike up Stuart Street compared to attempting to cycle up with only 3 gears. Electric motor technology has been around for well over 100 years and the efficiency of electric motors has not improved much since the early 1900s. It was the modern battery technology of the green scooter which made all the difference as to being able to travel up a steep hill without undue effort.
A question arises as to whether production of modern batteries is truly sustainable using only renewable energy sources without fossil fuel subsidies. This is one of many issues which I will address in my book In Search of Steady State Revisited. Answers to this and similar questions are provided by current cutting edge research publications in peer reviewed international journals and not in popular books, Internet blogs, and media outlets which are too frequently based on second and third hand etc. unreliable information.
In 1999 I was on sabbatical in Karlsruhe, Germany. My host did not own a car. He used the public electric tram system to travel from home to the university. Whenever he needed to use a car, he used a community owned car by booking his use in advance. In New Zealand most families duplicate purchases of capital goods that are used on a regular but not 24/7 basis - for example lawn mowers etc. A more sustainable approach would be to use a community owned lawnmower on a roster basis. Community owned transport is also more sustainable than privately owned transport. Public transport systems - bus and rail - in New Zealand provide for community use, but the current scales of the networks are limited and public transport networks cannot cater for all needs outside of the networks. New Zealanders currently make duplicate purchases of cars when their need, use, and convenience of transport exceeds that provided by public transport. An increase in the scale of public transport systems using electricity instead of diesel and community ownership rather than private ownership of cars would be more sustainable.
In response to your email, I also have some concerns about electronic technology including the Internet and GPS. Both technologies have positive and negative aspects. For me, the biggest negative aspect of the Internet is the proliferation of misinformation. It takes a great deal of effort to bypass misinformation, identify primary sources, and then establish the reliability of that information. Nonetheless, for me the positives outweigh the negatives so long as there is no censorship of information that erodes civil rights. So far, I am not aware of any such censorship with Internet connections in New Zealand.
Electronic technology enables and offers tangible benefits for society. For example, it is satellite and GPS technology that has enabled and assisted climate change researchers to establish the extent and cause of climate change. Electronic technology provides the potential for disbenefits which include unwarranted surveillance. I understand the only way to ensure GPS location privacy with a mobile is to remove the battery. Electronic technology also enables the machinery of war such as drones and surface to surface and surface to air missiles. I do not have any answers as to how the negatives of electronic technology can be eliminated. For me, the actual benefits of electronic technology outweigh the potential disbenefits.
Once again, there is a question as to whether our current electronic technology can continue to be sustained using only renewable energy sources without fossil fuel subsidies. So far the answer is not clear cut and certain. There are many feasible paths towards transitioning from a growth and fossil fuel based society to a steady state and renewable energy based society, but not all paths are viable in the long run because there are many supply chains with limits which have yet to be fully unravelled. We cannot afford the fallacy that what is feasible is also viable. What is certain is that we all need food, water, and shelter. If we are unable to provide the primary essentials of food and water at a community level, then any hope for long term sustainability is unrealistic. I agree that SCAN is about community-led, bottom up action. Community leadership and action is also about community preparedness and, without being overly pessimistic, this might be needed sooner than later. Who knows what the future holds for us over the next decade or so.

Followup on 1 November 2018 Blog on Sustainable Energy Transition & World Food Energy Flows
Sgouris Sgouridis and Denes Csala have a website on Sustainable Energy Transition which includes Presentations, Articles, & Models. The PowerPoint presentations make for excellent viewing. The source file of their interactive Sustainable Energy Transition model can be downloaded from the website and run using the software AnyLogic Personal Learning Edition (free software, download here)
Csala has also modelled the EROEI of World Food Energy Flows where the EROEI of food production is the ratio of the energy content of food to the energy required to produce that food. An interactive world map which shows the EROEI of food production for each country scan be viewed at the link here.
A number of energy analysis studies made 40 years ago, for example Gerald Leach’s research published in his book Energy and Food Production, estimated that the EROEI of pre and semi-industrial food production systems is much greater than industrial food production. This is because industrial food production relies on fossil fuel-based fertilisation and mechanisation. The EROEI of food production can be estimated at the farm gate, after processing into bread for example, and after arrival at the supermarket. Each process along the supply chain from producer to consumer involves additional fossil fuel energy which reduces the EROEI. In some cases, the EROEI is less than 1.00 which means the consumer is effectively eating oil. It takes more energy to produce the food on the consumer’s plate than the energy content of the food.
The New Zealand EROEI for food production as at 2011 on the World Map shows as being 0.28 while a number of other countries have an EROEI much greater than 1.0. Detailed information (inputs, outputs, imports, exports etc.) for New Zealand can be viewed at the link here. The same information for other countries can be accessed from the same website page.
The above study on Food Energy Flows and changes over time shows a trend of a declining EROEI for some countries. A number of counties both export and import food (sometimes the same food) and some countries rely heavily on imported food. As we transition from fossil fuels to renewable energy, local food production which makes use of natural fertilisers will become increasingly more necessary. Countries with high population densities which rely on imported food are likely to face severe difficulties. It would be ironic if so-called under developed countries which have a pre or semi-industrial food production system are able to make a smoother sustainable energy transition than more highly industrialised countries.

Modified Copy of email to SCAN: The Need to Ban ALL Drilling for Oil and Gas in New Zealand
A major issue needs to be addressed - banning additional drilling permits for oil and gas in New Zealand is not enough. See the following:
"Greens want Labour to toughen gas ban" - News Room 6 November 2018
Gareth Hughes's Supplementary Order Paper to close the loophole which allows continued offshore drilling was unsuccessful. The Labour Party and NZ First outvoted the Greens.
We need to impress upon the Labour Party, NZ First, and the general public that in order to limit the impact of Climate Change to 1.5 degrees Celsius, 80% of all proven reserves of oil and gas must stay in the ground. I have attached a peer reviewed international journal publication that addresses this issue (download from ResearchGate here). This conclusion is well covered in the global media as follows:

Modified Copy of email to SCAN: Dynamics of a Global Transition from Fossil Fuels to Renewables
I have attached the following peer reviewed international journal publication that addresses the dynamics of a global transition from fossil fuels to renewables while mitigating the impact of Climate Change:
Quantifying the narrowing net-energy pathways to a global energy transition by Sgouridis, Csala, and Bardi, 2016. (Download here)
The New Zealand Government should pay heed to the results of this publication and similar dynamic studies of energy transition instead of adhering to the recommendations in government commissioned reports published by Vivid Economics. The government commissioned reports do not take into account the physics and dynamics of an energy transition.
A key result of the above Sgouridis et al. publication echoed by a number of peer reviewed publications is that a transition from fossil fuels to renewables should take place not only as soon as possible, but also at a high a rate as possible while still reducing GHGs. Unwarranted delays in transition would make a transition more difficult, if not impossible. Enabling an immediate and rapid transition without increasing GHGs will require diversion from production that bolsters continued use of fossil fuels to that of renewables and allied infrastructure. Reductions in wasteful consumption will also be necessary. Business as usual is not an option.
I have extracted the following quotations in chronological order where "RE" is Renewable Energy and "SET" is Sustainable Energy Transition:
"The early and fuel-switch phase out profiles offer a wider range of easier paths than the delayed transitions primarily because of their lower investment peaks. ...
... In every case, the trajectory of a successful SET consists of a sustained acceleration in the rate of investment in RE. … In all cases, the installation rates should increase by several orders of magnitude within the next three decades. ...
... Importantly, further delays in the rise of RE investments cannot be compensated by subsequent additional acceleration because the decline in net energy from the carbon constrained fossil fuels would be insufficient to power the transition without energetically impoverishing society or exceeding the carbon cap ...
... we need the energy from fossil fuels to transition away from their use. This requirement is analogous to ‘the sower’s strategy’ … the long-established farming practice to save a fraction of the current year’s harvest as seeds for the next. Fossil fuels are finite but we can ‘sow’ what these fuels provide: energy and minerals to create the capital needed for the transition…
... Given the uncertainties in some of the critical parameters, through a mapping of a range of possible trajectories we show that the growth rates of RE installed capacity should continue unabated at above 30% [per year] until at least 2020 and then slowly ease but still remain above 10% almost until 2030. …
…The challenge of a SET before the end of the 21st century under climate constraints is unprecedented in magnitude, scope, and ambition. It is, nonetheless, doable if we adopt a global ‘sower’s strategy’ and proactively invest an appropriate amount of the fossil energy available today into building a sustainable energy future with concrete annual targets. In this respect, the currently observed deceleration in RE deployment (28% growth rate for PV in 2015 from a peak of 75% in 2011 and 17% for wind from a peak of 24.5% in 2010) begins to diverge from early transition trajectories and should be redressed."

Modified Copy of email to SCAN: Plastic Roads and Public Versus Private Transport
Thanks for directing me to the website on recycling waste plastic in the construction and maintenance of roads. I have followed up on this lead and I have downloaded a number of magazine articles, research publications, and videos. The following are samples:
‘Can plastic roads help save the planet?’ - BBC News link here
‘Heard about miracle plastic roads - here’s why it is not solution to our plastic problem’ - The News Minute link here
Most news coverage on plastic roads is positive, and the ones that are not address valid environmental concerns about plastic entering our waterways and polluting our atmosphere.
So far, "plastic" roads are a mixture of recycled plastic and bitumen. A mixture of plastic and bitumen is more durable than asphalt, but this method of disposal of "waste" plastic is but only one method out of many. A number of articles refer to "100% recycling" of plastic. This expression is a misnomer because there is no such thing as 100% recycling except in nature over long time frames. This is because it is too energy cost prohibitive to 100% collect any material that has become dispersed. There are diminishing returns of collection for each additional unit of energy used in any collection process of dispersed material.
A number of comments on websites that promote the use of "waste" plastic in roads suggest that this is a supposed solution to a problem that should not exist in the first place. Instead of rejoicing at what seems to be an easy way of disposing of "waste" plastic, focus should be on reducing the need of disposal in the first place by using alternative to plastics which are biodegradable. Using "waste" plastic in roads should not be regarded as a sustainable recycling of plastic when alternatives to plastics should be used.
In terms of opportunity cost, I query whether "waste" plastic is more valuable for re-use as a chemical substance. Fossil fuels are burned in engines because petrol and diesel are currently so cheap. When fossil fuels are hopefully replaced by renewables, fossil fuels in the ground and "waste" plastic will still remain useful for their chemical composition. When "waste" plastic has eventually been full utilised as far as possible in the distant future, remaining fossil fuels in the ground might still be mined for use in chemical production even though the energy cost of extraction from the ground would be greater than the energy content of the fossil fuel. There again, it might be energy cheaper to create hydrocarbons by extracting CO2 from the atmosphere using renewable energy to drive the process.
Going back to private electric vehicles and roads together as a transport system, and assuming that "plastic" roads are not only feasible, but also viable, I still maintain that public transport systems should be given priority over the promotion and purchase of private electric vehicles. The first priority, of course, should be investments in renewable energy.
A question arises as to who will do the investing? Middle class New Zealanders simply do not have sufficient disposable income to purchase solar collectors which feed back into the grid, nonetheless electric vehicles. It is at the community and national level that investments in renewable energy, public transport systems, and other supporting infrastructure are possible. The benefits of these investments will be enjoyed by not only current generations, but also future generations. If these investments are not made, then future generations will carry the costs. The investments which need to be made are social investments which are enjoyed by individuals.
Money is a claim on the use of future resources. In order for society to be able to sustain itself, the use of future resources for the needs of society must and should take precedence over that of the individual. This leads me to suggest that the importation of SUVs and cars with an engine capacity greater than 2.0 litres should be immediately banned. Alternatively, importation of cars with a petrol consumption less than 6.0 litres per 100 km on the open road should be banned. The details can be debated. The principle is that the days of conspicuous consumption are over and society can ill afford to allow the profligate use of fossil fuels to drag down our future prospects of a sustainable society.
In recent weeks petrol taxes in New Zealand have increased and the response of the general public has not been favourable. It is forgotten or unknown by many that in the early 1970s petrol prices at the pump in New Zealand increased threefold overnight as a result of the OPEC trade embargo. A few years later petrol prices at the pump doubled overnight. The New Zealand public's reaction to what is an insignificant recent increase in petrol prices by way of comparison doesn't bode well with the necessary increases in the price of carbon to reduce GHGs. Our current Emissions Trading Scheme is ineffectual and it seems as if a revised ETS instead of a Carbon Tax will be foisted upon us. As I have stated before, whatever carbon pricing system is adopted in New Zealand, an essential feature of the system is that it does actually result in reductions in GHGs, especially in the light of the recent IPCC Report on the need for urgency to reduce GHGs now and not later. The system also needs to be equitable so that those on low incomes are not unduly penalised.

Modified Copy of email to SCAN: Continued Economic Growth is Unfeasible
I have attached a key peer reviewed international journal publication on the unfeasibility of continued economic growth:
"More growth? An unfeasible option to overcome critical energy constraints and climate change" by Capellan-Perez, Mediavilla, de Castro, Carpintero, and Miguel, 2015 (Download from ResearchGate here). The publication is quite technical, so I have highlighted the relevant introduction and conclusions.
I have listened to the BBC podcast "The Real Story-2018 10 12 - Climate Change Tough Choices" emailed to us a few days ago. During the podcast I heard one of the participants promote "sustainable growth", an abysmal ignorance of the fundamental principles of sustainability. Promotion of Green Growth - continued economic growth - during a transition from fossil fuels to renewables while at the same time reducing GHGs perpetuates false expectations and muddies important investment decisions which need to be made.
Among many issues and global events that are currently taking place, the latest detailed PowerPoint documentation from Jeremy Leggett on the Ponzi nature of fracking in the USA which will inevitably collapse (download from SlideShare here) and the UK Government's nonetheless determination to undertake fracking (The Guardian link here) suggest that we are in for very interesting times. Over the next few years we will be privileged to be witness to an unfolding of what could be the most pivotal period of human civilisation.

Modified Copy of email to SCAN: The Need to Invest in Renewables ASAP
The IPCC Report 2018 (download here) focuses on the dynamics of CO2 emissions and the subsequent changes in climate. Mitigation of the impact of climate change obviously involves in reductions in GHGs and the only way to do this and retain some semblance of a modern civilisation in the future is to transition from fossil fuels to renewable energy and to reduce our energy consumption per capita while at the same limiting our population growth.
I have attached the publication “From Fossil Fuels to Renewable Energies” by Mediavilla, Miguel, and de Castro on the dynamics of this energy transition which might be of interest to you (download here). The message of this publication is the same as that of the most recent IPCC report. There is not only urgency in the need to reduce GHGs now, but also urgency in transitioning to renewables ASAP. The implications are clear - we need to make sacrifices now in order to address both issues and if we do not, then future generations will carry the cost of our inaction in the past and any lack of appropriate response over the next few years.

Modified Copy of email to SCAN: Using CO2 to “Recycle” Energy
VICE Australia has posted a video on Facebook titled “Why don’t we recycle energy?” The comments section states "The technology is ready. This is how CO2 could be used to fuel our society”. The video itself states that CO2 in the atmosphere can be converted into high grade fuel which can be used by planes and uses the expression “recycling energy”. For those who are not conversant with this technology, I have attached a peer reviewed international journal publication on turning CO2 into fuels (download from ResearchGate here)
The expression "recycling energy" is misleading and, by a process of Chinese whispers, has resulted in a number of Internet sites which claim that technology has solved our energy and climate change problem. No, it has not. Both the use of hydrogen as fuel in engines and fuel processed from CO2 are energy carriers and not energy sources because they both require more energy to create than the energy they deliver. The difference is that when you burn hydrogen in an engine you get water, whereas when you burn CO2 based fuel in an engine you get get CO2, carbon monoxide, and even carbon depending on how well the fuel is burned.
It might be better to use CO2 based fuel in planes than using fossil fuels stored in the ground because the process of converting CO2 into fuel and then burning it doesn't add CO2 to the atmosphere, hence the incorrect use of the word "recycling" in the expression “recycling energy”. However, there is a rider. The process of converting CO2 into fuel requires the use of energy and, in addition, the plant and machinery required to enable the process to take place also requires the use of energy and materials. The CO2 based fuel cannot bootstrap itself as the EROI of the fuel is less than 1. If the total system requires the use of fossil fuels, as most likely it does, then CO2 is added to the atmosphere. If the total system uses only electricity generated by renewables (solar panels, wind turbines, hydro etc.), then this use of electricity might be very wasteful. It comes down to opportunity costs - what other uses could that electricity be put to. There is yet another rider. So far renewable energy is unable to bootstrap itself. Manufacturing of solar panels, wind turbines, etc. still require the use of fossil fuels which adds CO2 to the atmosphere. The supply chains which support and enable an alternative energy system need to be examined in order to determine whether the energy system is truly sustainable.
A number of systems can appear to be both feasible and viable when looked at in isolation. A principle of systems dynamics is that second and third etc. surrounding layers of the system need to be considered to determine true long-term viability and sustainability. This is why I have concerns about sustainable roading for transport when many people regard the use of electric vehicles as a solution to mitigate the impact of climate change. Strategies and policies to mitigate the impact of climate change should identify the true long-term energy costs of options and rank them in terms of priority before implementation.
The latest IPCC Report 2018 (download here) has given us a wake up call and there are many decisions to be made. A systems dynamics viewpoint is needed for each decision, but most publications and books focus on only one or a few aspects which impact on each decision. Comprehensive systems dynamics guides are few and far between. One example is the book "Earth at a Crossroads: Paths to a Sustainable Future" by Hartmut Bossel, 1998. Vaclav Smil also provides a similar approach. A purely monetary approach alone to decision-making is inadequate and could lead to wasteful decisions. A dynamic energy and materials systems approach should be included when making decisions that are vital to our future wellbeing.

Modified Copy of email to SCAN: Materials for Transport Systems
In my search for publications on sustainable roading materials, I have come across the following important and useful book which can be downloaded here for free personal use: "Sustainable materials with both eyes open" by Julian Allwood and Jonathan Cullen, 2012.
“This evidence-based survey presents a holistic vision of options for a sustainable future by going beyond efficient and clean production to the inclusion of material efficiency and the reduction of demand. Beginning with an all-encompassing examination of the uses of the five most important materials—steel, aluminium, cement, plastic, and paper—this exploration delves into the entire lifecycle of these materials, from smelting and goods manufacture to final recycling. Through evidence drawn from this analysis and real-world commercial enterprises, the study submits creative solutions for achieving manufacturing efficiencies and the same functionality or services using less material, and identifies potential economic outcomes from these scenarios.”
Sub-sections of chapters can be downloaded separately (I assume they can be read on-screen with a browser PDF plugin - my computer is set up to download PDFs) or the entire 356 page book can be downloaded (28 MB) for personal use.
The free PDF book version doesn't have the usual front pages, bibliography section, and index pages which I assume the bought version includes. Each page has a header restriction stating "This electronic copy is provided free for personal use only". The search facility of a PDF reader overcomes the limitation of no index to a certain extent. A PowerPoint summary can also be downloaded (10 MB).
With regards to sustainable roading materials, I have still yet to come across a sustainable smooth roading system suitable for modern high speed vehicles, but which excludes the use of asphalt and concrete. In the distant future, use of fossil fuels will be far too valuable for use on roads and concrete which makes use of energy intensive cement will be prohibitively expensive. A steel rail transport system still seems to be the lowest energy cost system for local and city-to-city transport networks.
It might well be that New Zealand and other countries will have a larger percentage of electric vehicles by 2050, but an appropriate sustainable transport system must include not only the type of vehicles, but also the surface on which these vehicles run. Private vehicles in the future might well prove to be a luxury society is ill able to afford compared to walking, cycling, and local networks of light rail.
Fossil fuels have enabled concentration of populations in large cities and a rural to urban drift where 80% of populations now live in towns and cities. A reversal in urbanisation might be inevitable in the future with a need for greater independence of industrial production capability within each smaller centre. An electrified city-to-city railway network removes the need for total independence of industrial production and will enable specialisation within different centres.

Revised Copy of email to SCAN: Transport System Priorities
Transition from fossil fuels to renewables over a short time frame will involve a lot of economic activity. This economic activity will involve use of energy. Despite some claims to the contrary, it is physically impossible to entirely decouple economic activity from the use of energy. Fundamental requirements for survival - food, water, shelter, and transport require the use of energy. In the long run, renewable energy sources and infrastructure will need to sustain itself - manufacturing, maintenance, and replacement - but use of fossil fuels will initially be required to enable a transition from fossil fuels to renewables. Renewables alone cannot bootstrap the transition.
A transition from fossil fuels to renewables without increasing GHGs will require forgoing many current economic activities. Production was diverted to the war effort during WWI and WWII and many sacrifices were made. Is it overly melodramatic to suggest that civilisation currently faces a war-time effort. I liken our response to mitigating the impact of climate change to that of the frog being slowly heated to boiling point in a pot. There is currently indecision as to how serious our situation is and what our appropriate responses should be.
The long term level of transport that we will be able to sustain will follow after the necessities of food, water, and shelter have first been met. It is sensible to grow food locally. Water sources, including aquifers, need to be protected. Local sustainable forestry would also be sensible to sustain shelter.
It would be a serious mistake to assume that first priorities should be given to retaining our current predominant mode of private transport - cars - by replacing petrol and diesel cars with electric cars. First priority should be given to a city-to-city electrified railway network.
Local transport needs in Dunedin can be largely met by walking and cycling supplemented by public transport. The level of local public transport systems that is possible after primary needs are met is suggested by looking back in history at energy consumption per capita in New Zealand and the type of local public transport systems used back then. Our network of trams and trolley buses served our city well before diesel took over in the 1950s.
Electric buses are more flexible than trams and electric trolley buses which are restricted to overhead lines, but I keep coming back to whether we will be able to sustain a network of roads in the long term without fossil fuels. Without fossil fuels we will have no asphalt and concrete is energy intensive. I suggest that a network of railway tracks for light rail will be far more easily sustained than a network of roads. This applies especially to a city-to-city electrified railway network. We have had roads without asphalt and concrete for centuries, but these roads would not be able to provide a smooth surface for the speed of transport that we are accustomed to. A railway track can provide smooth and high speed transport at a much lower cost.
A transition will involve change, and basing decisions on what we currently enjoy could result in misguided investments. We can ill afford to make mistakes in investment. The Dunedin Caledonian Grounds running track and cycling velodrome constructed in the late 1950s is an example. The wind swept site was never suitable for a running track and is now used by the Warehouse and Pak 'n Save. Dunedin constructed a replacement running track at a more suitable location at Logan Park. In the future Dunedin will not be able to afford similar mistakes in investment.
There are many decisions to be made as to what our priorities should be when making a transition from fossil fuels to renewables. These decisions should be based on physical realities and not wishful thinking. Where there is uncertainty, we should apply the precautionary principle.

Revised Copy of email to SCAN: Richard Heinberg’s Response to IPCC Report
Richard Heinberg has written an article in the Pacific Standard which is headlined “The New IPCC Report Offers Climate Solutions That Depend on Magic: To solve the crisis, we'd have to slow growth. And no one wants to admit that.”
I agree with what Richard Heinberg has written. Expectations of retaining economic growth during a transition from fossil fuels to renewables is unrealistic. Reducing GHGs during a transition where current plant and infrastructure are replaced with renewables over a relatively short time frame is impossible unless resources used to manufacture and maintain current frivolous capital goods are diverted to that required for such a transition. Sacrifices would be inevitable.
Nicholas Stern and Vivid Economics promote "Green Growth" which is a fantasy as described by Richard Heinberg. Do intelligent people promote green economic growth because they truly believe this is possible, or do they promote that which is more palatable to politicians who rely on continued voter support.
Green Growth promotes a transition from fossil fuels to renewables which is an essential step to mitigate the impact of climate change, but what concerns me is that misguided beliefs as to what is possible might result in misguided investments in infrastructure which cannot be maintained in the long term. We have only one shot at this, and the precautionary principle is at play here. All investments in renewable energy sources and infrastructure must be demonstrably and truly sustainable without any hidden subsidies and costs. For example, a transition to electric vehicle will reduce GHGs, but how are our network of roads going to maintained? Shouldn't our priorities be first on upgrading and electrifying our city-to-city railway network and local light rail systems rather than attempting to retain a road transport system that was possible to construct and maintain using fossil fuels, but which cannot necessarily be maintained when use of fossil fuels is phased out.

Revised Copy of email to SCAN: Links Between Climate Change, Sustainability, and Monetary Policy
You may have seen on TV the latest IPCC report on climate change. Here are some examples of global coverage of the report:
"We have 12 years to limit climate change catastrophe, warns UN" - The Guardian link here
"Planet has only until 2030 to stem catastrophic climate change, experts warn" - CNN link here
"Report: we have just 12 years to limit devastating global warming" - VOX link here
The IPCC link to the report is here
All countries need to mitigate the impact of climate change by investing with urgency in alternative sustainable energy sources and infrastructure. A question arises as to how this investment is to be financed. One source of finance is by stopping all subsidies to the fossil fuel industry, divesting from fossil fuels, and then diverting these funds to investments that mitigate the impact of climate change. Another source of finance is by national Reserve Banks issuing interest free credit (money) in the same way that state houses houses were financed by the New Zealand Government in the late 1930s.
The following is the introduction to the Hansard recording of the parliamentary debate on the 1936 Reserve Bank of New Zealand Amendment Bill (download here):
"In 1936, the First Labour Government put forward legislation to nationalise New Zealand’s central bank (The Reserve Bank of New Zealand). The legislation also enabled The Reserve Bank to issue credit (money) for the construction of housing and public infrastructure without the need to borrow the money at interest from overseas.
... Thousands of affordable State Houses were built and the unemployed were given work in meaningful jobs.
...The wealth generated for New Zealand allowed for the establishment of a welfare system that became the envy of the world. It also enabled New Zealand to emerge from the great depression sooner and in better economic condition than most countries around the world."
There are solutions as to how to finance with urgency a transition from fossil fuels to sustainable energy sources and infrastructure. We should not hobble ourselves in an age of urgency with defunct monetary policies where government deficits are regarded as a negative to be avoided. Government borrowing of money from private banks which create money and then charge interest on that money is, indeed, a burden on current and future generations, whereas creation of interest free money by the Reserve Bank is not because subsequent government debt does not accrue interest and the Government does not need to pay back debt to itself.

Copy of email to SCAN: Recommended YouTube Video
I have just finished viewing the YouTube video "Tenth Anniversary Lehman Brothers at the European Parliament" presented by Steve Keen. This presentation is one of the best that I have seen that highlights neoclassical economics ignorance of how the economy really works by assuming that banks act as intermediaries of lending instead of actually creating money from debt.
The presentation will not be everyone's cup of tea, but if you are interested in understanding the links between the role of banks, the economy, financial crises, and inequity, then this is a must see. The pressure on the economy to pay off interest on debt is a fundamental driver for continued economic growth. In other publications Steve Keen recommends a Jubilee of debt where debt is written off.

Modified copy of email to SCAN: Limits of Education
I view climate change as a symptom. The root causes of climate change include population growth, an addiction to economic growth which requires growth in the use of energy (currently fossil fuels), our food production system which relies on fossil fuels in the form of fertilisers, the use of false and misleading indicators of wellbeing (GDP), our monetary system (creation of money is based on debt which is a claim on future resources), and our discounting system. Inequity is also a symptom of root causes. If we are to effectively mitigate the impact of climate change and take appropriate action now, then in my opinion we need to address the root causes.
We act upon what we believe, and rational belief requires understanding. The pathway to understanding is education, but there is a limit to what education can achieve. I have just had a look at the YouTube video "Sea Secrets 2018 James Balog - The Human Element: A Photographer's Journey in the Anthropocene" which addresses the content and purpose of the film "The Human Element". The film itself is possibly better screened for audiences in the USA where there is much more division than in New Zealand as to what causes climate change and the degree of impact. The strong message of the video presentation (and I assume also the film) is that belief systems must be based on evidence and that there is an active campaign to distort the truth about climate change.
Solutions include identifying barriers and impediments which block appropriate action, and ways and means of counteracting misinformation. Notwithstanding this, James Balog concedes in the discussion time at the end of the above video presentation that people with a certain hard wired ideology cannot be persuaded to change their belief system about climate change regardless of any hard evidence. There are also deniers here in New Zealand and Dunedin, and I doubt that SCAN would ever be able to get these people to view any films about climate change regardless of how well we promote a film.

“History of oil and gas production from shale in pictures and charts” by Jeremy Leggett 2018
I recommend viewing Jeremy Leggett's PowerPoint slide show (114 slides). Very much food for thought when so much reliance is placed by the USA (and England) on fracking. In reality, fracking is not only an environmental disaster, but is also a financial Ponzi operation supported by ever increasing debt. The slide show indicates potential economic disruption when fracking operations inevitably become bankrupt.

“Making carbon pricing work for citizens” by Klennert et al. 2018. - Download link here
The publication “Making carbon pricing work for citizens” by Klennert et al. 2018 is worthwhile reading (with effort). When I come across a publication which is highly technical, especially if the paper is based on high level mathematics well beyond my own level of mathematics, I read only the abstract, the introduction, and then the conclusions in order to get value out of the publication. The above publication is well worthwhile reading, but there is little value for me in the conclusion section. By reading and highlighting the entire paper, I have come across valuable information which is relevant and applicable under specific situations, but not necessarily so in general, hence the lack of practical guidance in the conclusion section. The main message of the publication for me is that the "best" carbon pricing system for any country needs to be tailored for that specific country.
I have reservations when I see economists talking about "efficiency". For me the main criteria of a carbon pricing system is "effectiveness" and equity. Many carbon pricing systems have so far not been effective. This is largely due to the politics of implementation, regardless of whether the carbon pricing system is a Carbon Tax or an Emissions Trading Scheme. I suggest that it is impossible to determine in advance which is the optimal system in terms of effectiveness based on the histories of previous carbon pricing systems and implementation. My training mate in swimming had the saying that "all swimming is good swimming" as opposed to a specific training schedule, and this is true to a certain extent. It is better to make a decent start with a sub-optimal system than to delay while arguing about which is the optimal system. Monitoring the progress of effectiveness and equity and accordingly tweaking the system can be done later on. For me, making a decent start is more important.

Today is Overshoot Day: Earth Overshoot Day website link here
“Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere. Earth Overshoot Day is hosted and calculated by Global Footprint Network, an international think tank that coordinates research, develops methodological standards and provides decision-makers with a menu of tools to help the human economy operate within Earth’s ecological limits.
To determine the date of Earth Overshoot Day for each year, Global Footprint Network calculates the number of days of that year that Earth’s biocapacity suffices to provide for humanity’s Ecological Footprint. The remainder of the year corresponds to global overshoot. Earth Overshoot Day is computed by dividing the planet’s biocapacity (the amount of ecological resources Earth is able to generate that year), by humanity’s Ecological Footprint (humanity’s demand for that year), and multiplying by 365, the number of days in a year:”

Copy of Email to SCAN: David Fleming & Use of Podcasts for Research & Education
I really appreciate your links to information about various issues on sustainability and I follow through with each link and subsequent links.
Even though I have collected many GB of publications, videos, and podcasts, David Fleming and his work is new to me. I have downloaded the podcast you recommended which I have yet to listen to (60 minutes) and I have followed through with links to a number of other sources of information which I have included below.
I see that David Fleming advocated a Trading Energy Quotas (TEQ) system to reduce GHG emissions. This is essentially a rationing system which I fully support. I note that Wise Response advocates James Hansen's Fee & Dividend system which I also fully support. I fully support any system or hybrid system which will be effective in reducing GHG emissions and I do not support any system that will allow a minority to benefit financially at the expense of others or which is ineffective. As to which system will actually be implemented at Government level comes down to politics.
I also see that a film about David Fleming will be released very soon. We need to keep a track on this.
Another thing I noticed is that it took David Fleming 30 years to write his book "Lean Logic". This is encouraging at one level in that I despair at times that I have collected information on issues of sustainability at a faster rate that I am able to process. At another level I am aware that I most likely don't have 30 years left to update my 1978 sub-thesis "In Search of Steady State". A few weeks ago I decided I had collected enough information and that I should now make a start on developing a number of YouTube videos and e-learning courses on various issues of sustainability. But no, I realised there were gaps in my knowledge - Carbon Sequestration by Trees and Soil for example - and I subsequently did a big download of videos and primary publications which I have yet to process and then recommend on my website. From now on I will try and go half and half with my time both continuing to collect primary sources of information and making use of that information by creating educational YouTube videos and interactive e-learning courses.
I have just finished listening to the podcast on David Fleming ( Ecoshock link here ) Doing so has emphasised for me that listening to podcasts for information is not the way to undertake research because podcasts are linear in form and one has to listen to the entire audio and take notes in order to glean information. With a transcript of the podcast I could have processed the information in 5 to 10 minutes instead of taking 60 minutes by being able to scan read and highlight what I hadn't known before, new concepts that make logical sense and which increases my understanding, and hard data evidence. By all means listening to podcasts is of value for those who wish to do so for pleasure and entertainment, but using this format of information for research purposes is far too time consuming. I see from a recent email that a sustainability organisation is advocating podcasts for educational purposes. The linear format of podcasts for the purpose of education is inferior to books and publications and especially films, video clips, and interactive e-learning courses which include graphics and animation.

Copy of Email to Seniors Climate Action Network (SCAN): SCAN Submission on Zero Carbon Bill
Thank you for the time and effort you have put into our SCAN submission. Well done. I also endorse your submission on behalf of SCAN.
With regards to how best to reduce GHG emissions, I prefer a pure carbon tax on fossil fuels with an immediate full tax and not gradual increases in pricing over a number of years, but in my personal submission I advocated a hybrid scheme.
My reasons for preferring an immediate and full carbon tax on fossil fuels are as follows:
1. We have already delayed far too long in reducing GHG emissions. A gradual reduction in emissions over a number of years will only exacerbate our current situation because the level of GHGs in the atmosphere is cumulative. The severity of climate change can only get worse and even more so with delays in reductions. We risk the impact of runaway climate change and all efforts should be made to reduce GHGs as soon as possible.
2. Climate change is the price our current and future generations will have to confront due to our consumption of fossil fuels which was and still is encouraged by an artificially low price which did not and does not take externalities into account. The longer we delay reducing our GHG emissions, the greater will be costs of climate change in the future.
3. A full carbon tax on fossil fuels will have an immediate impact on reducing current levels of fossil fuel consumption and increasing investment in renewable energy sources and corresponding infrastructure, plant, and machinery.
4. The revenue generated by a full carbon tax can be used for investment in renewable energy and infrastructure etc. and to mitigate the impact of increases in prices for those who are least able to adjust.
5. A full and immediate pure carbon tax on fossil fuels will be disruptive, but New Zealand was able to accommodate and adjust to a tripling in the price of petrol at the pump in the 1970s followed by a doubling in price. The level of a carbon tax can be adjusted so that the level of disruption is no greater than that experienced in the 1970s.
6. The current generations have benefited from the use of fossil fuels and have a moral duty to carry the burden of reducing GHGs as soon as possible. Any unnecessary delays in reducing GHG emissions would transfer that burden and the impact of more severe climate change onto future generations.
My reasons for advocating a hybrid scheme are as follows:
1. In my opinion, New Zealand is highly unlikely to adopt a carbon tax as opposed to an Emissions Trading Scheme (ETS) and any scheme that is adopted and implemented is likely to be a graduated scheme which delays reductions in GHG emissions. One reason why the New Zealand Government is likely to adopt an ETS is well explained in detail in the book "The SIMPOL Solution" by John Bunzel and Nick Duffell, 2018 (Amazon.com link here). Essentially, each Government will avoid actions that will put their own country at a disadvantage. The result is that there will be a race to the bottom whereby the least positive action will be implemented by each country.
2. Given that a carbon tax is likely to be rejected and that an ETS is favoured by the Productivity Commission and also the Coalition government, advocating a hybrid scheme is more likely to be considered as an option. A hybrid scheme combines the advantages of a carbon tax and an ETS. If an ETS is adopted, then it will be a coup if a hybrid ETS is implemented. One can only hope.

Today is Earth Day
Today is Earth Day which prompted me to hunt down a film on Economic Growth for community screening by SCAN (Seniors Climate Action Network based in Dunedin, New Zealand).
I have been aware of the film "GrowthBusters - Hooked on Growth" by Dave Gardner for a number of years now, but I hadn't viewed the film as I was already a convert some 40 years ago. Today I paid my US $9.99 and downloaded the 54 minute film in 1080p format. A US $2.99 online version is also available. “GrowthBusters - Hooked on Growth” is the best film I have come across so far which challenges economic and population growth.

My Submission to the New Zealand Zero Carbon Bill (Additional Comments on Submission Form)
75% Vote by Parliament to set and change targets and policies
In order to ensure stability of political purpose and cross-party representation, the Carbon Bill should include the requirement that climate change targets and policies are set and changed only when there is a 75% of all Members of Parliament endorsement vote.
Immediate reductions in methane gas emissions
All countries, including New Zealand, need to reduce GHG emissions as soon as possible in order to reduce the risk of runaway methane emissions from thawing tundra. Most methods of reducing GHG emissions take time, including planting saplings to absorb carbon dioxide. In the meantime, seasonal adjusted levels of GHG in the atmosphere increase monotonically.
Methane emissions by ruminants in New Zealand contribute a major source of the nation’s carbon dioxide equivalents. A 10% reduction in methane emissions could be implemented within weeks by Government decree to reduce herd numbers. Farmers around the world have been paid not to grow crops. New Zealand can and should likewise pay its farmers to reduce their herds of ruminants and assist transition to alternative food production. In the 1970s the New Zealand economy adapted to a three-fold followed by a two-fold increase of petrol prices at the pump. This scale of adaptation far surpasses that of an immediate 10% reduction in herd numbers. New Zealand has the economic resilience to absorb the costs of paying farmers to immediately reduce their herds by 10% which would be followed by subsequent reductions in herd numbers as farmers transition to alternative food production.
I recommend that Government immediately decrees a 10% reduction in ruminant herd numbers in New Zealand.
100% renewable electricity.
New Zealand needs to phase out use of fossil fuel-based generation of electricity by 2050 and according to a confidence & supply agreement between the Labour Party and the Green Party, the nation’s Climate Commission will be requested to plan the transition to 100% renewable electricity by as early as 2035. However, in its 2018 Draft Report, the Productivity Commission’s recommendations R12.1 to R12.4 for the Electricity Authority on page 433 do not include the need and urgency for Government to invest in renewable energy projects in its programme of works. The Draft Report states on page 321 that "if reducing emissions from electricity generation significantly increases the costs of electricity, this could delay the electrification of other sectors where the reductions are potentially larger." An Emissions Pricing Scheme can provide Government with revenue and this revenue can be used by Government to invest in renewable energy projects to maintain stable electricity prices. A 2017 survey by Carl and Fedor which tracks current global carbon revenues has established that Cap-and-trade systems (ETS) earmark 70% of revenues for “green” spending. The New Zealand Government can and should follow suit by either investing directly in renewable energy projects or by subsidising smaller scale renewable energy projects initiated by City Councils, community groups, or individuals.
I recommend that Government invests in renewable energy projects using revenue generated by an adopted Emissions Pricing Scheme in order to attain 100% renewable electricity by 2050.
Electrification of the New Zealand city-to-city railway network.
The Productivity Commission’s 2018 Draft Report addresses electrification of the North Island Main Trunk line and the advantages of doing so on page 310, but does not include a recommendation to electrify New Zealand’s city-to-city railway network. The Draft Report assumes and endorses that market place forces alone will result a major transition from fossil-fuelled vehicles to EVs by 2050. A major uptake of EVs is technically feasible, but is not necessarily viable given the high private costs of purchasing EVs and replacement of their batteries, whereas an essential electrification of New Zealand’s railway network is both technically feasible and viable provided Government undertakes the commitment to do so.
I recommend that Government electrify the city-to-city New Zealand railway network.
Examination of the continuation to provide power to the Tiwai Point aluminium smelter
The Productivity Commission’s 2018 Draft Report states on page 294 that “Electric vehicles are one of New Zealand’s most promising mitigation opportunities.” A 100% fleet of electric vehicles in New Zealand by 2050 would require substantial additional electricity generation. The Draft Report addresses ways of reducing demand for electricity in a number of sectors in the economy and mentions on page 333 that the aluminium smelter plant at Tiwai Point could be “incentivised” to help smooth demand peaks and reduce the need for on-call thermal generation. The Tiwai Point aluminium smelter plant currently uses 570 MW of electricity which is about 15% of current peak hydro electricity output. This level of continuous consumption of electricity begs the question of whether the Tiwai Point aluminium smelter plant’s continued use of electricity should take priority over New Zealand’s need for additional electricity during the transition phase from fossil fuels to renewable energy. A comprehensive study of peak demand and risk should include not only “incentivisation” to help smooth demand peaks but also address the issue of whether the Tiwai Point smelter plant should continue to use such a large percentage of New Zealand’s hydroelectricity output.
I recommend that Government carries out a study of the impact of the Tiwai Point aluminium smelter plant continuing its current consumption of electricity when additional electricity will be needed by electric vehicles and electrification of a city-to-city New Zealand railway network.
GDP is an inadequate indicator of wellbeing
The two different economic models developed by Vivid Economics (Vivid) and the New Zealand Institute of Economic Research (NZIER) to gain insights into the economy-wide impacts of reaching different emissions reductions targets are both seriously flawed. This is because their projections of progress are based on projections of GDP which is not an indicator of wellbeing. GDP conflates all forms of economic activity regardless of positive or negative impacts on wellbeing. An example is the economic activity of rebuilding required after earthquakes hit Christchurch. Few people would claim that citizens in Christchurch were better off after the destructive earthquake and during the rebuild. GDP makes no adjustment for leisure time. The number of work hours can increase rather than decrease in order to retain a standard of living. GDP counts only those goods and services that are recorded through official markets and leaves out home production and black-market activity. GDP makes no adjustments for the distribution of goods and services. For example, a minority of the population can enjoy higher standards of living as GDP per capita increases while the majority struggle more and more to make ends meet. GDP does not measure externalities of economic activity. An example is the deterioration of our waterways in recent years due to pollution generated by the agricultural sector.
Nobel prize-winning economist Joseph Stiglitz noted at a World Economic Forum in Davos, Switzerland in 2016 that "GDP is a poor way of assessing the health of our economies and we urgently need to find a new measure." There are alternative indicators of welfare. For example, the Index of Sustainable Economic Welfare accounts for both pollution costs and the distribution of income and the Genuine Progress Indicator adjusts for factors such as income distribution, adds factors such as the value of household and volunteer work, and subtracts factors such as the costs of crime and pollution.
I recommend that Government replaces GDP as a measure of wellbeing with OECD endorsed indicators of wellbeing.
Assumption that New Zealand should strive for economic growth.
The Ministry for the Environment (MFE) FINAL- Zero Carbon Bill - Discussion Document and the Productivity Commission’s 2018 Draft Report both assume that New Zealand is able to and should strive for continued economic growth during the transition from fossil fuels to renewables. A 2% increase in economic activity each year would result in a doubling of economic activity in 35 years’ time. It is highly questionable whether this target should be attempted given the need to reduce greenhouse gases rather than increase them. Some proponents claim that GDP and energy can be decoupled, but there are physical and thermodynamic limits to the extent that decoupling can take place. A transition from fossil fuels to renewable energy will, of course, reduce greenhouse gas emissions, but a major problem is that such a transition will require use of fossil fuels to set up new infrastructure, plant, machinery, vehicles etc. (embodied energy) at the very same time as the need to reduce greenhouse gas emissions. In order to satisfy both requirements, use of fossil fuels will therefore need to be diverted from that of consumption to that of investment. Expectations that business as usual can and will continue during a transition from fossil fuels to renewable energy and that economic growth can and should continue at a time when we need to reduce greenhouse gas emissions are unrealistic.
Hybrid Emissions Pricing Scheme
The Productivity Commission’s 2018 Draft Report makes the following Recommendation R4.1 on page 416:
“The Government should reform the NZ Emissions Trading Scheme rather than replace it with a carbon tax. The reforms should provide a good balance between control over unit supply (i.e., an effective emissions cap) and protection against excessive volatility in the price of emission units. The reforms should also provide the institutional and regulatory underpinnings for a credible and efficient market in emission units, as well as transparency and forward guidance to incentivise long-term investments in lower emissions.”
There are clear cut and distinctive advantages and disadvantages of a pure Carbon Tax versus a pure Emissions Trading Scheme (ETS) which are addressed in the preamble and findings that precede R4.1. Given the combination of the preamble and findings followed by the wording of R4.1, the intent of R4.1 seems to seek the advantages of both a Carbon Tax and an ETS. Such a scheme would be a hybrid scheme as described in the public literature and recommended by a number of sources. The devil of implementation of a hybrid scheme lies within the details. For example, a hybrid scheme can be an ETS which not only caps a limit on emissions, but also sets a minimum price cap which effectively results in a minimum carbon tax.
I recommend that New Zealand adopts a Hybrid Emissions Pricing Scheme with a cap on emissions and a minimum cap on carbon pricing with full Government control over the auction process.

New Zealand Ministry of the Environment (MFE) Discussion Document on Zero Carbon Bill & Submission
I have just finished reading the MFE publication “Our Climate Your Say: Consultation on the Zero Carbon Bill” and I have found this publication to be a fair and balanced summary of the issues. By reading the full publication I no longer have concerns that using the online Submission Form would lock me into a limited choice of options. I will now use the online Submission Form with greater confidence that I will able to provide the feedback I feel is necessary by selecting one of the available options within each question and then adding my feedback in the corresponding Notes field. For example Question 2:
2. If the Government sets a 2050 target now, which is the best target for New Zealand?
Net Zero Carbon Dioxide - Reducing net carbon dioxide emissions to zero by 2050
Net Zero Long-Lived Gases and Stabilised Short-Lived Gases - Long-lived gases to net zero by 2050 while also stabilising short-lived gases.
Net Zero Emissions - Net zero emissions across all greenhouse gases by 2050.
I will be selecting the third option "Net Zero Emissions: Net zero emissions across all greenhouse gases by 2050" and not the second option because this option refers to "stabilising" short-lived gases (methane). "Stabilising" is not the same as "Reducing". In the Notes field I will address the need to focus immediately on reducing methane gas emissions.
I have tested out the Notes field with a large block of text to see whether there is too small a limit on the number of character allowed. My full block of text was able to be copied and pasted without any problems.

Recommended publications and books
I recommend the following international refereed journal publications:
‘Energy, EROI and quality of life’ by Jessica G. Lambert, Charles A.S. Hall, Stephen Balogh AjayGupta, and Michelle Arnold, 2014 – ResearchGate link here
‘EROI of different fuels and the implications for society’ by Charles A.S. Hall, Jessica G. Lambert, and Stephen B. Balogh – ResearchGate link here
The above publications are highly technical, but the data and conclusions in these publications are more reliable than what is available from many website pages or magazine articles. I am a firm believer in collecting and relying on data in primary sources than what is very often misquoted in secondary and dubious tertiary etc. sources.
The information in the above publications in combination with that in the following book strongly suggest what is possible with respect to a transition from fossil fuels to renewables:
'Sustainable energy - without the hot air' by David Mackay, 2009 – Amazon.com link here This book addresses the scale of renewable energy which would be needed in order to fully replace fossil fuels.
I have recommended the following books on this website. These books indicate where best to target reductions in greenhouse gas emissions. I believe it is worthwhile to rearrange these into the categories that fit within "Society's Hierarchy of Energetic Needs" as shown in Figure 12 of the above "Energy, EROI and quality of life" publication:
'How bad are bananas: The carbon footprint of everything' by Mike Berners-Lee, 2010 – Amazon.com link here This book addresses the greenhouse gas emissions from the embodied energy involved in products, processes, and activities.
'Drawdown: The most comprehensive plan ever to reverse global warming' edited by Paul Hawken, 2017 – Amazon.com link here This book ranks where best to target reductions in greenhouse gas emissions

Consultation Process on the forthcoming Zero Carbon Act in New Zealand (modified 2 July 2018)
New Zealand is currently undergoing a consultation process on the forthcoming Zero Carbon Act. A publication on this process can be downloaded from the Ministry for the Environment (MFE) here. On Tuesday 26 June I attended a consultation meeting held in Dunedin where the Minister of Climate Change, James Shaw, addressed the audience. MFE staff then gave a PowerPoint presentation which included an emissions profile showing the proportion of different types of greenhouse gas emissions in New Zealand based on carbon dioxide equivalents (CO2e) - carbon dioxide contributes 44% of which 43% is transport, methane contributes 43%, and nitrous oxide contributes 12%. The meeting finished with a short question and answer session.
Each member of the audience was provided with a pamphlet, “Our Climate. Your say!”, which summarises the consultation process. We were asked to indicate on the pamphlet our choice(s) of what the Commission for Climate Change should do from a list, and the extent that we agreed or disagreed on the statement that “New Zealand needs a clear plan on how we are going to both assess and adapt to the risk of climate change to our people, our country and our economy”. The pamphlet also set out different options for “What is the best 2050 climate change target for New Zealand”. The wording of these options as set out in the above MFE publication and paralleled in the pamphlet are as follows:
[MFE wording] Net zero carbon dioxide by 2050: this target would reduce net carbon dioxide emissions in New Zealand to zero by 2050 (but not other gases like methane or nitrous oxide, which predominantly come from agriculture).
[Pamphlet Wording] a. Net Zero Carbon Dioxide. This target would reduce carbon dioxide to net zero. To get there we will need to reduce emissions from the energy and transport sectors – where most of our carbon dioxide emissions come from.
[MFE wording] Net zero long-lived gases and stabilised short-lived gases by 2050: this target would reduce emissions of long-lived gases (including carbon dioxide and nitrous oxide) in New Zealand to net zero by 2050, while stabilising emissions of short-lived gases (including methane).
[Pamphlet Wording] b. Net Zero Long-Lived Gases and Stabilised Short-Lived Gases. We would need to reduce carbon dioxide and other long-lived gases like nitrous oxide to net zero. We would also need to stabilise short-lived gases, like methane which comes mostly from livestock.
[MFE wording] Net zero emissions by 2050: this target would reduce net emissions across all greenhouse gases to zero by 2050.
[Pamphlet Wording] c. Net Zero Emissions. This would be the most ambitious target and would require emissions from all greenhouse gases (both long-lived and short-lived) to be reduced to net zero. To get there, there will be changes to how we use our land, we would need to plant a lot more trees and innovate more.
Information on greenhouse gases and their carbon dioxide equivalents on the NIWA website is helpful in deciding which of the above options is best. Jeanette Fitzsimons in her article "Cutting methane hard and fast is the best path to Carbon Zero" on The Spinoff website presents a strong argument for focusing on methane. Methane is initially many times more potent than CO2 and there is a risk that if we do not cut back on emissions of methane soon enough, then there could be a runaway positive feedback effect of methane emissions from thawing tundra. Jeanette Fitzsimons supports Option B. For me, Option A is definitely not an option and supporting Option B alone is insufficient to convey the urgency and need to reduce methane gases. The wording in option B uses the words "stabilise short-lived gases" (methane) which is not the same as "reduce short-lived gases".

Modified copy of email to Seniors Climate Action Network (SCAN) - Feedback on “A Tale of a City and Townships, A Story of Sustainability”
Thank you all for your feedback on my "A Tale of a City and Townships: A story of Sustainability". Much appreciated.
Forty years ago in 1978 a group of architectural students in their final year sub-thesis came to the conclusion that then current settlement patterns in New Zealand were unsustainable. A number of researchers today are now coming to the same conclusion. For example Ted Trainor writes “a core claim of The Simpler Way project (2017) is that a sustainable and just society based on 100% renewable energy supply is desirable and could be easily achieved, but only if there is a radical transition to new settlement patterns, economies, political systems, and most difficult of all, new values and non-affluent conceptions of the good life”.
Simpler Way website link here Simplicity Institute website link here Resilience.org website on The Simpler Way link here
My use of the walled city and domed townships is unnecessary to convey the well known and accepted principles of Central Place Theory. I used this story approach by way of poetic licence. Central Place Theory explains how the growth of cities became possible based on changes in transport costs. When humankind relied solely on travel by foot, concentration of populations in cities was impossible. As technology of transport developed - the wheel and the cart pulled by animals, boats then ships, improvements in road construction, the car which uses high grade fossil fuel and especially trucks - and the energy for use by transport increased, concentrations of populations in larger cities became possible. Central Place Theory also explains the process of reverse urbanisation.
The level of technology that is possible in the future depends on the average EROI of the energy that humankind is able to make use of. The costs of transport will depend also on the average EROI because there will be many competing demands for energy, and these costs will increase as the average EROI of a combination of fossil fuels and renewables decline to that of only renewables.
There is a lot of flesh to be inserted between the bones of my argument that a reversal of urbanisation will need to take place to ensure the sustainability of future human settlements. For example, I have not addressed the use and issue of nuclear power. One question which begs to be asked and answered is whether our current settlements patterns are desirable or not. Would a transition from fossil fuels to renewables be easier if we did not have concentrations of high density cities?
There are much larger cities around the world than Auckland, but how many countries have over one third of its population concentrated in one city? Countries like the UK and especially France have many smaller and dispersed settlements as well as large cities. I have travelled by plane over France a number of times and what was most striking for me when looking out of the window was that for mile after mile under the flight path there are villages after villages all closely connected by networks which mirror the patterns described by Central Place Theory. The settlement patterns of these connected villages and towns developed over centuries, whereas in New Zealand settlements developed comparatively recently when technology was much more developed and soon before when access to and use of fossil fuels took off. Do the same flight by plane over New Zealand and you will see very few village and townships that are close together. Populations are more concentrated and far apart with an extreme concentration in Auckland.
Urbanisation is still taking place in New Zealand. The population of Auckland is still increasing and higher density housing is touted as the answer. However, there are some signs of a reverse trend due to high house prices in Auckland. A number of families are choosing to buy homes in smaller towns and commute to Auckland. Ideally, employment in their new town is preferred, but is not always available. Should we encourage a continuation of urbanisation in New Zealand or should we support and promote living and working in rural towns and villages?
I have attached two articles on EROI which I suggest are a must read (Download here and here). As I have emailed before, Energy Skeptic's approach might seem extreme to some people, but I cannot fault her research approach which is to seek out what is realistically viable as opposed to feasible. I repeat my closing words on my website that it is more important to choose the right direction and pathway of change from the outset otherwise we might make the mistake of blindly pursuing alleyways with only a cul-de-sac at the end. Humankind can ill afford costly mistakes. Whatever fossil fuels we use from now onwards should be used wisely to subsidise a transition to renewables. It is doubtful whether renewables would be able to bootstrap a transition by itself without fossil fuels subsidies and the legacy of technology that has been made possible by using fossil fuels in the past.
Sustainability is about being able to continue for a long time into the distant future and because we are all mortal, our efforts today will have the greatest impact on future generations. Should we care and take action when we are unlikely to reap the full benefits of our efforts during our own lifetime? We know that answer for ourselves and we need persuade others to be of the same ilk.
I have also attached an article on Local Food Production which might be of interest (download here).

A Tale of a City and Townships, A Story of Sustainability
The following ideas were prompted by the futuristic film “Escape from New York City” in which Manhattan Island is walled off in 1995 and turned into a prison. When watching the film, I immediately became aware that the poetic license of the film did not address the need for a continuous flow of food and water etc. for the prisoners. A high-density city simply cannot be self-sufficient and sustain itself if it is cut off by a wall or boundary.
There is a similar cutting off system boundary in Stephen King’s book “The Dome” and the video series based on the book. A township and surrounding countryside is cut off from the rest of the world by a transparent dome. The township can be sustainable and it would have sufficient food production potential to have a surplus.
An extreme case of a system boundary is Robinson Crusoe on a desert island. It is possible for Robinson Crusoe to survive so long as the island can provide food, water, and shelter. The level of survivorship depends on the tools that are available and Robinson Crusoe’s industry. The addition of Man Friday increases possibilities.
What is common to all three scenarios is the need for food and water. The extent of shelter will depend on what is available. If food and water is not available at a location, then inhabitants cannot survive. If it is possible to move across the system boundary, then efforts will be made to do so.
A bounded high-density city cannot provide sufficient food production because the potential to grow enough food for one person per unit area is much less than the number of persons needing food per unit area.
The population of the townships and surrounding countryside within each dome can be self-sufficient and not all townspeople will be required to grow food.
If the boundaries between a city and a number of surrounding township enclosed by domes are removed, then it is feasible, though not necessarily viable, to transport surplus food from the countryside to the city.
In order to produce surplus food for a city, more townspeople and more energy slaves in the form of farm machinery could be used to grow the surplus food.
Farm machinery and transportation of food from townships to a city requires the use of energy.
Fossil fuels will eventually become unavailable (the EROI will inevitably decline to 1.0) and humankind will need to depend on renewable energy.
The EROI of renewable energy is a lot less than that of current fossil fuels.
The EROI of energy and the magnitude of the energy flow production that can be provided by renewables both limit what is possible to sustain within human settlements.
When the EROI of energy declines below a minimum level, priority and preference will be given to the production of food which is local instead of transporting food over long distances.
Townships could shift closer to the city to reduce this distance, or the population of the city could move to the townships.
It is easier for the city population to shift to the townships in order to make use of existing shelter and infrastructure in the townships and build additional shelter in the townships than to shift entire townships closer to the city.
As the EROI of energy declines, there would be a reversal of urbanisation because inhabitants in the city need to seek local food production.
The type of society we will have in the future will have a hierarchy of what it needs followed by what it desires.
One of the systems that society will want to retain is that of knowledge.
A knowledge system requires storage and means of transfer from generation to generation, each of which requires energy.
The level of sophistication of humankind’s future knowledge system will depend on the EROI of renewable energy.
An indication of the type of society that is possible in the future can be suggested by the type of energy and the energy slaves per capita used by previous generations.
A transition from fossil fuels to renewables will require an investment in new infrastructure and capital stock.
To avoid malinvestment, it is wise and sensible to invest in a future that is possible rather than one which we desire to have based on what we already enjoy.
The correct direction of transition is of more immediate importance than numeration of the scale or magnitude and timing of transition. Necessary adjustments can be made as we go along.
A reversal of urbanisation will assist a transition more so than attempting to adapt our current cities to accommodate a decline in the EROI of energy. This principle applies more so the greater the density of population in each city.
The message of my above argument is that current settlement patterns cannot be sustained. The degree of urbanisation in New Zealand continues to increase and is encouraged and enabled by those who promote growth in GDP. The need to reduce greenhouse gas emissions is but only part of the pathway and transition to sustainability for future generations. A principle of systems dynamics is to always consider the system above that which is under current scrutiny, otherwise the best of intentions and efforts to address and change what is under scrutiny might be confounded.

Sustaining Public Capital Stock
One of the $1 books I purchased at the recent Regent Theatre Book Sale here in Dunedin, New Zealand, is 'The World Without Us' by Alan Weisman, 2007 - Amazon.com link here I followed the recent TV series which I assume was based on this book. Both the TV series and the book make for very interesting reading and provide an alternative perspective and insight into our impact on the environment. The book describes the decay process of our buildings and infrastructure when humankind is no longer around to sustain its capital stock.
I am especially interested in the decay and degradation process of capital stock and the life cycle costing of sustaining capital stock - the cycle of new capital stock, maintenance, refurbishment, replacement and recycling. Most people are focused on the growth of capital stock and take the maintenance, refurbishment, and replacement of our existing capital stock for granted. The resources required to sustain our current capital stock, nonetheless add further growth, are substantial. It is very easy to live off and "consume" our capital stock provided by previous generations by deferring necessary maintenance and refurbishment. This also applies to the fertility of land which also should be sustained from generation to generation.
Growth in GDP (for example economic activity to add to capital stock) can be achieved at the expense of the condition and accelerated depreciation of our current capital stock. Investment for private benefit can be diverted away from providing the necessary resources to sustain public capital stock. Those who advocate investment to promote growth in GDP generally also advocate lower taxes, taxes which are needed to sustain our current public capital stock. Examples of public capital stock include our schools and hospitals which have suffered from deferred maintenance over the last decade. Our public capital stock should include our national railway and electricity supply systems. These systems were provided and sustained by previous generations and ownership of any public capital stock, especially our water supply systems, should never be sold off to private enterprise.
If sustaining our electricity supply system requires a replacement of fossil fuels with renewables, and doing so requires extending its use of renewables to enable a transition away from fossil fuels used by cars to electricity used by EVs, then our taxation system should be tailored and geared to enable this transition regardless of political lobbying by special interest oligopolies and monopolies based here in New Zealand and overseas. There seems to be a direct conflict between private interests and the public good in New Zealand and very likely also elsewhere. Private interests tend to focus on short term benefits whereas genuine sustainability focuses on the long term. Our elected leaders have a responsibility and duty to take on board a long term view on behalf of our current and future generations. The forthcoming Zero Carbon Act here in New Zealand should and needs to mirror this responsibility and duty.

Modified Copies of Emails to Seniors Climate Action Network (SCAN) added to Personal Blog
I haven’t updated my personal blog on a regular basis as my focus has been on processing the information that I have been collecting since October 2015. However, it has occurred to me that there is useful information contained in a number of the emails that I have sent to fellow SCAN members on a regular basis since September 2017. Today I have made a start on adding modified copies of these emails to my Personal Blog in the reverse chronological order that I wrote the original emails.

My submission to the New Zealand Productivity Report Low-emission economy NZ - DRAFT April 2018
I commend the New Zealand Productivity Commission on its report Low-emission economy NZ - DRAFT April 2018. Given the terms of reference, including the exclusions imposed on the inquiry, the Draft Report is comprehensive and thorough. The majority of the well-considered recommendations should go a long way towards reducing greenhouse gases.
Hybrid Emissions Pricing Scheme
The Draft Report makes the following Recommendation R4.1 on page 416:
“The Government should reform the NZ Emissions Trading Scheme rather than replace it with a carbon tax. The reforms should provide a good balance between control over unit supply (i.e., an effective emissions cap) and protection against excessive volatility in the price of emission units. The reforms should also provide the institutional and regulatory underpinnings for a credible and efficient market in emission units, as well as transparency and forward guidance to incentivise long-term investments in lower emissions.”
There are clear cut and distinctive advantages and disadvantages of a pure Carbon Tax versus a pure Emissions Trading Scheme (ETS) which are addressed in the preamble and findings that precede R4.1. Given the combination of the preamble and findings followed by the wording of R4.1, the intent of R4.1 seems to seek the advantages of both a Carbon Tax and an ETS. Such a scheme would be a hybrid scheme as described in the public literature and recommended by a number of sources1, 2. The devil of implementation of a hybrid scheme lies within the details. For example, a hybrid scheme can be an ETS which not only caps a limit on emissions, but also sets a minimum price cap which effectively results in a minimum carbon tax2.
I recommend that New Zealand adopts a Hybrid Emissions Pricing Scheme with a cap on emissions and a minimum cap on carbon pricing with full Government control over the auction process.
Impact of Peak Oil
A number of recommendations in the Draft Report are predicated on the expectation of a business as usual scenario during a transition phase through to 2050 and there is an implicit assumption that potential disruptions can and will be mitigated. This is understandable given that the primary purpose of the report on page iii is to provide guidance on how to “manage a transition to a lower net emissions economy, while still maintaining or improving incomes and wellbeing”. The restrictions of the Terms of Reference imposed on the Draft Report may have resulted in an omission to address the impact of peak oil, an omission which is a major flaw of the report. Chapman (2014) summarises the debate about peak oil as follows3:
“Up until recently Peak Oil was a major discussion point crossing from academic research into mainstream journalism, yet it now attracts far less interest. This paper evaluates the reasons for this and on-going relevance of Peak Oil, considering variations in predictive dates for the phenomenon supported by technological, economic and political issues. Using data from agencies, the validity of each position is assessed looking at reserves, industrial developments and alternative fuels. The complicating issue of demand is also considered. The conclusions are that, supported by commercial interests, an unsubstantiated belief in market and technical solutions, and a narrow paradigmatic focus, critics of Peak Oil theory have used unreliable reserve data, optimistic assumptions about utilisation of unconventional supplies and unrealistic predictions for alternative energy production to discredit the evidence that the resource-limited peak in the world's production of conventional oil has arrived, diverting discussion from what should be a serious topic for energy policy: how we respond to decreasing supplies of one of our most important energy sources.”
“…the evidence is that conventional oil production has peaked and prices will rise, though this is unlikely to benignly encourage a shift to new fuels. … Rather than continuing to argue for or against the topic, Peak Oil should be acknowledged as part of a complex energy situation with the realisation that cheap fuel is no longer available and we now face circumstances where prices will increase and high energy-based growth will be limited. …Like the oil crisis of the 1970s, this is a situation of great importance that requires leadership, discussion and analysis on a global level. Many aspects of modern life will be impacted by conventional oil output falling and co-ordinated action between diverse agents will be required.”
A transition from a fossil fuel based economy to one that is in turn reliant on renewable energy will be necessary regardless of the impact of climate change and the need to reduce greenhouse gases. A transition from fossil fuels to renewable energy will of course reduce greenhouse gas emissions, but a major problem is that such a transition will require use of fossil fuels to set up new infrastructure, plant, machinery, vehicles etc. (embodied energy) at the very same time as the need to reduce greenhouse gas emissions. In order to satisfy both requirements, use of fossil fuels will therefore need to be diverted from that of consumption to that of investment. Expectations that business as usual can and will continue during a transition from fossil fuels to renewable energy are unrealistic.
I recommend that the Final Report addresses issues of peak oil and allied contingency planning.
Meeting Peak Electricity Demand
The Draft Report states on page 294 that “Electric vehicles are one of New Zealand’s most promising mitigation opportunities.” An assumed 100% fleet of electric vehicles in New Zealand by 2050 would require substantial additional electricity generation. The Draft Report addresses ways of reducing demand for electricity in a number of sectors in the economy and mentions on page 333 that the Comalco smelter plant at Tiwai Point could be “incentivised” to help smooth demand peaks and reduce the need for on-call thermal generation. Comalco currently uses 570 MW of electricity5 which is about 15% of current peak hydro electricity output. This level of continuous consumption of electricity begs the question of whether Comalco’s continued use of electricity should take priority over New Zealand’s need for additional electricity during the transition phase from fossil fuels to renewable energy. A comprehensive study of peak demand and risk should include not only “incentivisation” to help smooth demand peaks but also address the issue of whether Comalco should continue to use such a large percentage of New Zealand’s hydroelectricity output.
In a submission to the Commerce Committee, The New Zealand Aluminium Smelters Limited (NZAS) wrote the following statement to Jonathon Young, Chairperson, Commerce Committee, on 12 March 20136:
“New Zealand Aluminium Smelters Limited (NZAS) welcomes the invitation to make a submission to the Commerce Committee’s consideration of the petition of Eric Roy MP requesting that “the House encourage the Government to see Meridian and Rio Tinto renegotiate a viable power supply contract to save Tiwai Point aluminium smelter, and note that 3,110 people have signed postcards supporting this request.
… During the 1960s, the New Zealand government granted the then owners of the Tiwai Point smelter, Comalco, 99 year water rights in order to develop both the Manapouri Power station and the NZAS smelter. Due to financing difficulties, Comalco could not finance both the Manapouri power station and the NZAS smelter. In order to keep the option alive, the Holyoake Government of the day acted to accept the water rights back from Comalco and in return finance and build the Manapouri power station. The Government also committed to provide to Comalco a 93 year power deal (until 2060) to supply affordable power to the smelter. In return, Comalco agreed that the power price structure would cover the operating costs of the Manapouri Power Station, pay back the capital cost of construction and provide a premium.
In short, Manapouri was built for a specific purpose – to provide long-term affordable power to the smelter, and the power station was paid for by the smelter owners, not the New Zealand tax payer. If the smelter had never existed, the power station would also not exist today.”
The above statement that the Manapouri Power Station was paid for by NZAS as an argument for NZAS to continue using electricity generated by the Manapouri Power Station is fallacious. It is equivalent to a tenant claiming the right to continue renting a property because the landlord pays down a mortgage on the property from the rent received. Ownership and control of electricity generated from the Manapouri Power Station belongs to New Zealanders and not NZAS.
I recommend that Government carries out a study of the impact of Comalco continuing its current consumption of electricity when additional electricity will be needed by electric vehicles and electrification of the city to city New Zealand railway network.
Electrification of City to City Railway Network
The Draft Report addresses electrification of the North Island Main Trunk line and the advantages of doing so on page 310, but does not include a recommendation to electrify New Zealand’s city to city railway network. The Draft Report assumes and endorses that market place forces alone will result a major transition from fossil fuelled vehicles to EVs by 2050. A major uptake of EVs is technically feasible, but is not necessarily viable given the high private costs of purchasing EVs and replacement of their batteries, whereas an essential electrification of New Zealand’s railway network is both technically feasible and viable provided Government undertakes the commitment to do so.
I recommend that Government electrify the city to city New Zealand railway network.

Modified copy of email to Seniors Climate Action Network (SCAN) - Progress on Submission to April 2018 Productivity Commission Report
After an extensive reading of the pros and cons of Carbon Tax vs Emission Trading Schemes, I have decided that a hybrid approach should be adopted. A hybrid approach can be incorporated in an ETS.
I am still processing the recommendations of the Electricity Recommendations which are as follows:
CHAPTER 12 - ELECTRICITY RECOMMENDATIONS
"R12.1 Given rapid changes in electricity-generation technology and potential effects of rising electricity prices on adoption of low-emissions technology in other parts of the economy, the Government should not use subsidies or regulation to favour particular technologies that generate low-emissions electricity.
R12.2 The Government should rely on an effective emissions-pricing system as the main instrument to achieve an efficient trade-off between emissions reductions in electricity and emissions reductions in other parts of the economy. The Government should be cautious in specifying targets for emissions within the electricity sector, and make sure that technology is available to meet them without significantly increasing wholesale electricity prices above the levels achieved with current technology."
I have highlighted in italics the recommendations that I feel uneasy about.
The majority of the recommendations in the April 2018 Productivity Commission Report will go a long way to reducing emissions of greenhouses gases from the burning of fossil fuels, but we still need to use energy which either does not involve the burning of fossil fuels (i.e. renewables) or which eliminates emissions of greenhouse gases when burning fossil fuels ( a new technology which could prove to be very expensive).
Setting up the infrastructure for renewable energy will involve using fossil fuels which are not necessarily burned in New Zealand (e.g. PV panels) and so too will replacement of vehicles, plant and equipment which currently make use of fossil fuels. And yet there is the assumption that we can continue to grow our economy during this transition phase while at the same time reducing greenhouse gas emissions. There are physical and thermodynamic limits to decoupling energy and GDP.
The April 2018 Productivity Commission Draft report focuses on reducing greenhouse gases, but does not address simultaneously phasing in replacement renewable energy. Who is going to generate the additional electricity that will be required. Is this going to be left entirely over to households (how many households can afford solar panels without a subsidy?) and the marketplace for private sector investment, or is the Government going to take a lead? Wind and solar, being intermittent, are unlikely to meet peak electricity demands. Geothermal energy can provide for peak demand and so too can the diversion of the current continuously supplied electricity to Comalco. Is the private sector expected to step in to provide additional geothermal electricity? There is no way that I would agree with privatisation of our water supply. Are we expected to accept privatisation of our energy supply? Ultimately reducing greenhouse gases to zero involves not only not burning fossil fuels but also providing a reliable replacement source of energy. This issue needs to be clearly addressed in the final Productivity Commission report.

Modified copy of email to Seniors Climate Action Network (SCAN) - Peer Reviewed Basis of Leaving Fossil Fuels in the Ground
On 10 May 2018 The Star published the article "Benefits of Gas Ignored by Government" by National MP, Michael Woodhouse who advocated continued gas exploration off the Otago coast. I have made every effort to track down international peer reviewed journal publications on the pros and cons of key issues of climate change and sustainability to ensure that my understanding of each issue is based on primary reliable sources of information rather than second hand sources which are far too frequently based on opinion rather than facts and hard evidence or on an incomplete understanding of the issues. The following video and publication provide counter arguments for leaving fossil fuels in the ground based on empirical research.
'The Extent, Nature and Geographical Distribution of "Unburnable" Fossil Fuels' - Christophe McGlade - YouTube link here
Publication in the Journal Nature - "The geographical distribution of fossil fuels unused when limiting global warming to 2 °C" by Christophe McGlade & Paul Ekins, 2015 - Download here
As an aside, I have come across an excellent YouTube series of videos on various issues of sustainability (35 videos): ‘AP Environmental Science Course’ - Paul Anderson - YouTube links here This series of videos provides an excellent resource for High Schools in New Zealand.

"Vivid Economics: We Generate Lasting Benefit For Business and Society by Putting Economics to Good Use
The challenge of securing sustainable and inclusive economic growth across the globe is fundamental to human well-being. From advanced economies facing a sectoral slowdown and stagnating median incomes, to emerging economies enjoying rapid growth in the shadow of increasing environmental and macro-economic risks, to low-income countries seeking to move onto new growth pathways, the need for a smart understanding of economic growth and development has never been greater.”
There is good solid information in these reports and yet a number of the conclusions and recommendations are counter to sound principles of sustainability. To me the reports seem to be written by accountants, financiers, bankers, and neoliberal economists making use of assumed increases in efficiencies, productivity, and growth in GDP. The modelling is based on assumptions and wishful thinking with scant regard to physical realities and what is actually possible. No mention is made of peak oil.
I have come across the following United Nations Conference on Trade and Development publication called:
"Trade and Environment Review 2013: Wake Up Before it is Too Late: Make Agriculture Truly Sustainable Now for Food Security in a Changing Climate"
In comparison to the above Vivid Economics reports, the United Nations report concurs with publications that I have at hand on sustainable food production and food security. The United Nations report is a much more useful report, albeit a focus on food security.

Low Emissions Economy Draft Report
I have made a start on reading and processing the 500 page ‘Low-emissions economy Draft Report’ published by the New Zealand Productivity Commission. As part of my processing I have made a start on highlighting various sections of the report. The following is a sample between asterisks:
***start on page i to iii
... Scope and aims
“The purpose of this inquiry is identify options for how New Zealand could reduce its domestic greenhouse gas emissions through a transition towards a lower emissions future, while at the same time continuing to grow incomes and wellbeing.
Two broad questions should guide the inquiry:
What opportunities exist for the New Zealand economy to maximise the benefits and minimise the cost that a transition to a lower net-emissions economy offers, while continuing to grow incomes and wellbeing?
To answer this, the inquiry will need to examine New Zealand's current patterns of economic activity and the ways in which these are contributing to the country's greenhouse gas emissions.
It will then need to consider the different pathways along which the New Zealand economy could grow and develop so as to achieve New Zealand's emissions targets, as well as respond to the physical effects of a changing climate. ...
... As part of analysing these pathways, the inquiry should also examine how they could affect broader economic objectives for increasing wellbeing and achieving higher living standards, including sustainability, economic growth (including productivity growth), increasing equity, social cohesion, and resilience to risk. ...
This inquiry should not focus on the suitability of New Zealand's current, or any future emissions reduction target. In addition, the inquiry should not focus on the veracity of anthropogenic climate change, and should only consider the implications of a changing climate to inform consideration of different economic pathways along which the New Zealand economy could grow and develop.”
***finish (my own italic highlighting)
***start of page 16
“Importantly, the Government has asked the Commission to look at actions that will maximise the benefits and minimise the cost of the transition, while continuing to grow incomes and wellbeing. Wellbeing is a very broad concept that encompasses a range of dimensions, including current quality of life and material conditions as well as sustaining the resources needed for future wellbeing (OECD, 2017b). Thinking on the ambit of wellbeing is still developing. The Treasury, for instance, is building on OECD work to adapt the concept to New Zealand’s circumstances and values (King et al., 2018).
At the core of sustaining future well-being are four types of “capital” – natural, human, economic and social (OECD, 2017). Mitigating climate change is, of course, central to preserving natural capital for future generations. Taking opportunities to maintain and build all these types of capital in the transition will contribute to future quality of life and material wellbeing. Innovation will be central, by finding ways to reduce emissions at low cost, while providing a means to develop new enterprises and ways of living that are consistent with a low-emissions economy. Reskilling will build the human capital needed; actions to reduce emissions will have other environmental benefits (such as improved water and air quality). Developing formal and informal institutions and organisations to set common goals and gain commitment will build social capital. Making sure the costs and benefits of the transition are understood and shared fairly, and that they unfold in a measured way, will also contribute to social capital.
While the Commission does not explicitly address the effects of mitigation efforts on wellbeing in this report, each chapter, in its own way addresses the relevant contributors. The Commission plans to draw these together more systematically for its final report.”
*** finish (my own italic highlighting)
My initial observations:
Growth in wellbeing in the report is essentially predicated on growth in GDP. I have done a word search for alternative indicators of wellbeing and cannot find any.
I have done a word search of "equity". The word "equity" is mainly used in relationship to financial equity. It seems to me so far that social equity has been skimmed over.
I have done a word search of "peak oil". There is no reference. I suspect the report does not address the impact of an inevitable decline in the rate of supply of fossil fuels in the long term.
I have done a word search of the words "limits" and "limits to growth". So far I cannot find any reference to limits to growth. There seems to be an assumption that climate change is a problem to be resolved without addressing the cause of the problem. Climate change is seen as a threat to sustainability and once that problem has been rectified, growth in the economy can and should continue.

Modified copy of email to Seniors Climate Action Network (SCAN) - Documentary -’Where to Invade Next’
Last night I watched the 2 hour documentary "Where to invade next" by Michael Moore that I had recorded from Maori Television a few days ago. The content of the documentary relates directly to the topic of my last email - wellbeing. Michael Moore visits a number of countries to investigate the quality of life there compared to the United States. The results are most illuminating - good examples of where higher levels of GDP per capita do not necessarily correlate with higher levels of wellbeing. One item I found of note in the documentary is the proportion of taxes that the United State spends on the military - 54% of discretionary spending. I followed up on this as follows on Quora.com - Link here The above documentary can be viewed on demand - Link here

Modified copy of email to Seniors Climate Action Network (SCAN) - Alternative Indicators of Wellbeing
GDP has been known to be a flawed indicator of human wellbeing for a number of decades. GDP measures economic activity regardless of whether that activity contributes to wellbeing or not. GDP also does not include unpaid activities which contribute to wellbeing. A number of studies have been carried out to make adjustments to remove negative activities and include unpaid activities. The results are very different to the published GDP figures. When these indicators are compared against GDP per capita, it can be seen that once a certain level of GDP per capita in a country has been achieved, there is little if any further increase in well-being or happiness in those countries with a higher GDP per capita. Reliance and subservience to GDP as an indicator of wellbeing is a fetish. The GDP emperor has no clothes on.

It is possible to improve wellbeing without increasing population numbers and, indeed, it is essential to limit population growth in order to ensure wellbeing of future generations. Our current problem of climate change is largely due to an enormous population expansion over the last century combined with an increasing use of fossil fuels per capita. As Al Bartlett has pointed out many time, continued population growth will now thwart efforts to curb generation of greenhouse gases.
Is it possible to retain our current level of well-being without increasing consumption of fossil fuel energy and resources before 2050? The answer to that question is one which seriously concerns me. Use of fossil fuel energy and resources will be necessary to set up the infrastructure for renewable energy generation and the replacement of fossil fuel based transportation systems and food production systems reliant on fossil fuels. This investment is very large and we need to make this investment at the very same time that we need to curb our use of fossil fuels so as to avoid runaway climate change. I fear that many if not most global citizens will want to continue with their current lifestyle which means that the large scale investment we need to make to enable transition would result in increases in greenhouse gas emissions.
In order to reduce our greenhouse gas emissions at the same time as investing in a transition to a renewable energy based economy, we need to divert current investment away from some non-essential and less-essential activities and all those activities which promote and assist a continuation of a fossil fuel reliant economy. Structural economic changes need to be made and some sacrifices will be unavoidable. We all need to be well aware of the conflict of interest between the desires of our current generation and the needs of future generations in order to come to a resolution. What the eventual outcome will be in 2050, I simply don't know. I know what I would like to happen, but wanting is not enough.

Modified copy of email to Seniors Climate Action Network (SCAN) - Insidious Assumption of Continued Economic Growth
The 2014 publication ‘Better Growth, Better Climate’ produced by the London-based Global Commission on the Economy and Climate can be downloaded here. The Executive Summary states the following:
"The Global Commission on the Economy and Climate was set up to examine whether it is possible to achieve lasting economic growth while also tackling the risks of climate change.
Its report seeks to inform economic decision-makers in both public and private sectors, many of whom recognise the serious risks caused by climate change, but also need to tackle more immediate concerns such as jobs, competitiveness and poverty. The report brings together evidence and analysis, learning from the practical experience of countries, cities and businesses across the world.
The report’s conclusion is that countries at all levels of income now have the opportunity to build lasting economic growth at the same time as reducing the immense risks of climate change. This is made possible by structural and technological changes unfolding in the global economy and opportunities for greater economic efficiency. The capital for the necessary investments is available, and the potential for innovation is vast. What is needed is strong political leadership and credible, consistent policies."
The above conclusion is absolute nonsense predicated upon the insidious fallacy that it is possible to sustain economic growth. I have attached an article by Al Bartlett which draws attentions to the same fallacious reasoning which we all need to be aware of and refute. (Download publications here from Al Bartlett’s website) Al Bartlett's wrote the article in 1994 with a revision in 1998. He made many predictions about the politics of sustainability which have since unfortunately transpired.
I have yet to read the Productivity Commission draft report. I hope that it is not also predicated on the assumption that it is possible to sustain economic growth.

My feedback submission on the Dunedin City Council Draft 10 Year Plan
The Local Government Act 2002 requires councils to consider sustainability issues in Long Term Council Community Plans. In August 2010 the Dunedin City Council commissioned a Peak Oil Vulnerability Analysis Report which included surveys on travel habits, private fuel consumption and vehicle dependence, and the effect of petrol prices. Peak oil is the point when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline.
The Peak Oil Vulnerability Report was co-ordinated by Dr Susan Krumdieck from EAST Research consultants based at Canterbury University and this report followed an earlier report on the likely impact of climate change carried out for the Dunedin City Council (DCC) by University of Otago Emeritus Professor of Geography Blair Fitzharris.
Dr Krumdieck's report Peak Oil Vulnerability: Assessment for Dunedin was released at a Dunedin City Council press conference on 6 December 2010. The report recommended that Dunedin should work on the following objectives:
1.Plan to reduce oil consumption by 50% by 2050.
2.Transition Dunedin’s urban form with central city lifestyle development, and urban villages, accessed by 100 km of safe bikeways and pedestrian zones and served by public transport.
3.Build an electric trolley bus system using efficient modern technology made in New Zealand.
4.Improve Dunedin’s average vehicle fleet efficiency to 5 litres per 100km by 2030.
5.Audit and track fuel use in all sectors, organisations and households and develop action plans.
The Otago Daily Times reported Mayor Dave Cull as saying “both reports would be used across departments to guide long-term planning.”
Over 7 years have now passed by since the release of the above Peak Oil Vulnerability Report, sufficient time for the DCC to take on board and address the above recommended objectives. In the meantime the New Zealand government ratified The Paris Agreement on 4 October 2016. The Paris Agreement entered into force on 4 November 2016 and will take effect from 2020. This agreement provides a framework for the global response to climate change. New Zealand has submitted a Nationally Determined Contribution (NDC) to reduce greenhouse gas emissions by 30 per cent below 2005 levels by 2030.
The document available for public viewing, The Draft Financial Strategy - Supporting Dunedin's 10 Year Plan states the following:
“We are planning to spend $864 million on capital projects over the next ten years, compared with $636 million in the last 10 year plan.
… There is significant pressure on the costs of delivering core services. Some of the drivers of increasing costs include:
the need to maintain, replace and renew core, ageing infrastructure
the obligation to build new infrastructure to a higher standard
the transfer of costs from central government without funding to offset the costs
increased compliance costs (e.g. treatment of stormwater)
the emerging impacts of impact of climate change on infrastructure and the wider community
increasing expectations from ratepayers to improve service levels
just getting on and fixing things to make Dunedin a better city.
… The Council is planning to invest in projects that will attract people to the city and enhance include:
building a bridge to connect the city with the waterfront
improving the safety of Dunedin’s transport network, particularly around the Peninsula Connection and Tertiary Precinct
upgrading the central city area
upgrading the Green Island Wastewater Treatment Plan
improving the resilience of Dunedin’s water supply and stormwater infrastructure
expanding the cycling network.” (my highlighting)
Under the Local Government Act 2002 (Reprint as at July 2017), Section 101B Infrastructure strategy,
“A local authority must, as part of its long-term plan, prepare and adopt an infrastructure strategy for a period of at least 30 consecutive financial years. … The infrastructure strategy must outline the most likely scenario for the management of the local authority’s infrastructure assets over the period of the strategy and, in that context, must … show indicative estimates of the projected capital and operating expenditure associated with the management of those assets … in each of the first 10 years covered by the strategy; and … in each subsequent period of 5 years covered by the strategy”.
The increasing costs of “emerging impacts of impact of climate change on infrastructure and the wider community” and the planned investment projects of “expanding the cycling network” are the only two infrastructure projects that address a response to the issues of climate change and peak oil. The scope and scale of these infrastructure expenditures are not included in the Draft Financial Strategy 10 Year Plan.
A search of the DCC website for additional documentation indicates that considerations of the impact of climate change are restricted to that of flooding and that the scope of cycleways is limited way below the scale recommended by the Peak Oil Vulnerability report. No mention is made of planning for an electric trolley bus system.
Some might argue that provision of public transport falls solely under the jurisdiction of the Otago Regional Council (ORC). However, where sustainability issues exist, there is a joint ORC and DCC responsibility to respond appropriately. Under the Local Government Act 2002, Regional councils’ responsibilities include Sustainable regional well-being and Regional land transport planning and contracting passenger services. Territorial authorities’ (DCC) responsibilities include Sustainable district well-being and The provision of local infrastructure. A region's councils (ORC and DCC) are required to meet and discuss how they will work together, and document this in a triennial agreement. They can set up formal arrangements – such as joint committees or council organisations, or informal arrangements, such as a Mayoral Forum or a Regional Forum, to help achieve common outcomes.
Given the serious impact of both climate change and peak oil on the future welfare of Dunedin citizens, I recommend that the following infrastructure projects be included in the current 2018 Dunedin City Council 10 Year Plan:
1.Initiation of a transition of Dunedin’s urban form with 100 km of safe bikeways and pedestrian zones and served by public transport as described in the Peak Oil Vulnerability: Assessment for Dunedin Report.
2.Initiation of an electric trolley bus system using efficient modern technology made in New Zealand as described in the Peak Oil Vulnerability: Assessment for Dunedin Report.

Modified copy of email to Seniors Climate Action Network (SCAN) - Spurious Precision of CO2e Estimates
I agree with George Preddy's comments on the spurious precision of the estimates of carbon dioxide equivalents (CO2e) in the Drawdown Project. Spurious precision of estimates can indeed lead to spurious claims of ranking. However, I wouldn't be too quick to be dismissive of the estimates themselves, a dismissal which could be misconstrued from George Preddy's ending quote "Lies, Damn Lies, and Statistics'. Given the complexities involved with any estimate of CO2e, we sorely need estimates of CO2e from a variety of hopefully independent sources in order to confirm the magnitude CO2e of different activities, services, and products. It is the magnitude rather than precision that provides a proper perspective as to where we are best able to reduce greenhouse gas emissions. Too much concentration on the trivial contributions diverts our attention away from the major contributions. I thoroughly recommend the following Kindle book (US $6.19) which is cheerily upfront about the precision of its estimates of CO2e:

After collecting and processing resources since August 2015 I am now firmly convinced of the following:
Action depends on Motivation which depends on Belief. Without Belief, there is no Action.
Belief in turn depends on many factors, including understanding. A full understanding is unnecessary. We are all reliant on information from many different sources. Confidence in the sources of information is necessary before accepting and taking on board partial understanding. As I have said a number of times before, we are all involved in an engagement of competing stories.

With regards to the report "Peak Oil Vulnerability Assessment for Dunedin" prepared for the Dunedin City Council by Professor Susan Krumdieck and EAST Research and its omission of food production (there are also other omissions)), I have come across the following far more comprehensive report on urban sustainability:

Modified copy of email to Seniors Climate Action Network (SCAN) - Comment on Publication “Peak Oil Vulnerability Assessment for Dunedin”
I have now fully read Susan Krumdieck's report and yes, lack of reference to food production is a major omission.
The DCC was required to commission such a report. I am subsequently less impressed. The DCC will not necessarily pay any heed to the report. Replacement of our electric trolley buses with diesel buses was a major mistake. It remains to be seen what action will be taken by the DCC to replace our diesel buses with electric buses. This is where SCAN can be involved, especially when the above report makes this recommendation.
To encourage Dunedin citizens of all ages to use bicycles will require a physical separation of bicycle lanes from cars on major routes. I for one want to use a bike as I did so daily between Mornington, Moana Pool, and Bayfield High School some 50 years ago. However, my perception of risk with age has changed. Being able to use the tunnel from Green Island to the City would solve a major impediment for older citizens in Green island to use a bike to go to the city. Using an electric bike over the hill is one solution, but at $3,000 it is an expensive solution for each cyclist. As an aside, if one already has a bike, it is possible to go electric with a conversion kit for under $1,000. Nonetheless, I for one will not cycle until there is a physical separation between bike and car on major routes. Other cities have done this. Dunedin can also do this

Modified copy of email to Seniors Climate Action Network (SCAN) - Grain Mill & Electric Drill
I have tried out my variable speed electric drill on my Victoria Grain Mill and it is so much easier than hand milling.
A few weeks ago I milled brown rice to a flour (it took 5 cycles of milling) and made some tortillas in my cast iron skillet on top of my electric stove. This was very successful. I have since learned that a tortilla press makes the process much easier than using a rolling pin, though two flat boards squeezed together with baking paper on both side of the tortilla mix will do the same job. Yesterday I tried to boil the rice flour to see what sort of desert would turn out. The taste of the result was OK but the texture was too much like paste.
Today I bought a pack of 4 nuts and bolts from Mitre 10 and cut the head off one of the bolts. I poured 3 cups of brown rice into the hopper of the mill (it can take 4 cups and possibly 5 cups) and I adjusted the resistance so that I could hand mill with ease. I didn't want the resistance to be too tight because I would risk burning out the motor of my drill and I would risk injuring my wrist when holding the electric drill still (I didn't use a jig). I then removed the handle of the mill and screwed the cut bolt into the end of the hand mill and attached my electric drill set to the lowest speed. It took possibly 10 second to mill 3 cups of brown rice. I poured the contents back into the hopper, screwed the milling plates closer together making sure the resistance against milling was too much, and then did a second cycle of milling. All finished within one minute.
I poured boiling water over half a cup of two cycle milled brown rice in a Pyrex bowl, stirred thoroughly, and put in my microwave on full for 5 minutes. I then added some more hot water, stirred, and cooked in my microwave for another 5 minutes. The result was a nice rice pudding with good texture. There is a balance between the number of cycles of milling, texture, and cooking time.
In summary, milling flour with a Victoria grain mill is a breeze when used in conjunction with an electric drill. It takes about as much time to pour the milled grain back into the hopper for an additional cycle of milling as it takes to actually mill each cycle. I recommend using a variable speed electric drill set at low speed.

Modified copy of email to Seniors Climate Action Network (SCAN) - City Prepping at a Community Level
In the following I am tossing out a few ideas. Within the context of City Prepping and recent comments to me about the possible need for a community grain mill and baking oven has set me thinking. A number of months ago I came across a website called Open Source Ecology which I added to my website with the following quote:
“The mission of Open Source Ecology (OSE) is to create the open source economy. An open source, libre economy is an efficient economy which increases innovation by open collaboration. To get there, OSE is currently developing a set of open source blueprints for the Global Village Construction Set (GVCS) – a set of the 50 most important machines that it takes for modern life to exist – everything from a tractor, to an oven, to a circuit maker. In the process of creating the GVCS, OSE intends to develop a modular, scalable platform for documenting and developing open source, libre hardware – including blueprints for both physical artefacts and for related open enterprises.”
In recent weeks I have focused on City Prepping at a personal level. The above website is essentially about City Prepping for technology at a community level. City Prepping could be regarded as a survivalist approach based on extreme pessimism. I am not so sure. I put forward that City Prepping is about preparing for a future that society is able to have in the long term as opposed to a society that we would desire to have. Preparation includes planning for contingencies and building in resilience.
Sustained growth of any form is simply impossible. A vision of a society that we are able to have in the long term must therefore be based on the attributes of a steady state settlement as opposed to that of a growth settlement. In my 1978 sub-thesis "In Search of Steady State" I developed such a summary and my 1979 journal article on sustainable future planning (attached) is based on this summary. Hartmut Bossel in his 1998 book "Earth at a Crossroads: Paths to a Sustainable Future" has adopted a similar approach to sustainable future planning and advocates that we must plan for a sustainable future that we are able to have rather than continue on our current path. Hartmut Bossel makes the following comment on page 28.
"This final step of the systems-analytical research led to an important conclusion:
The many alternative visions of sustainable futures that have been published in the past three decades all agree - with minor variations - on the fundamental principles and processes of Future Path B 'Partnership'
This is a remarkable result, and it is all the more remarkable as the different authors have arrived at these alternative visions independently of each other - in different countries, at different times, under different circumstances, in different languages. It can only mean that there is a common body of facts, knowledge, and ethical principles from which consistently the same conclusions can be drawn. "
The website "Open Source Ecology" merits closer examination. The About page continues as follows:
"The current practical implementation of the GVCS is a life size LEGO set of powerful, self-replicating production tools for distributed production. The Set includes fabrication and automated machines that make other machines. Through the GVCS, OSE intends to build not individual machines – but machine construction systems that can be used to build any machine whatsoever. Because new machines can be built from existing machines, the GVCS is intended to be a kernel for building infrastructures of modern civilization."
There are many links from the Wikipedia type structure of the above website to other websites on technology. One surprising (to me) link is to a YouTube video on how to have a hot shower in winter using the heat from a compost heap:
In a more serious vein, City Prepping for community based technology begs the following question - within the context of fossil fuels no longer being available for use in transport, to what extent is Dunedin and its surrounding farmland self-contained in terms of essential and necessary technology in order to avoid this community from eventually declining into a hunter and gatherer society? Do we have sufficient machines in Dunedin to make machines and maintain machines or are we totally reliant on other communities to provide this? If so, then what type of transport linkages between communities are needed and what type of transport technology is possible in the long term. I keep coming back to the need to electrify our national railway network between major centres otherwise each major community will need to be totally self supporting. Some of the risks that we face over the next number of decades is malinvestment in infrastructure and development. Investments need to stack up against the attributes of steady state settlements and not growth settlements. There are strong arguments that electric trucks are not the answer. Electric trains are a proven technology whereas electric trucks are not, and this does not take into account whether we will be able to maintain our roadways which are currently dependent on the availability of asphalt, a fossil fuel by-product.

Modified copy of email to Seniors Climate Action Network (SCAN) - Handmills
I paid $123 delivered for my Victoria hand mill. I hand milled 3 cups of whole wheat grain to a flour (5 cycles at a reasonable resistance) and it took me 12 minutes. It is certainly a workout. It is possible to remove the handle and attach an electric drill to do the work for you. All that is involved is buying a bolt with the same thread as the wing nut used to hold the handle in place and cutting off the head of the bolt, screwing the result into the shaft of the hand mill, and attaching the electric drill to the end. A jig or clamp could be set up to support and hold the electric drill in place. I might try out my electric drill sometime.
Three cups of whole wheat grain mills out into 4 cups of 100% wholemeal flour. I used 3 cups of this 100% wholemeal flour in my my usual bread recipe and baked a loaf of bread in my Panasonic bread maker. The dough didn't rise very much, but the resulting bread had some spring to it and was very tasty. Next time around I will use my flour sieve to increase the proportion of white flour (increase the gluten content). The dough will then rise much more.
I tried baking scones in a cast iron Dutch oven with a dome shaped lid all on top of the element of my electric stove. I followed a YouTube video tip and placed the Dutch oven on top of a cast iron skillet so as to avoid burning the bottom of the scones. The result was a failure. The bottom of the "scones" were well and truly burnt and the top was under baked. Advice over the Internet was to use a Dutch oven with a flat lid and ridge and to place hot embers on top of the lid so as to increase the inside temperature at the top of the Dutch oven.
I ordered such a Dutch oven, but before it was delivered I decided that control of the temperature would still be hairy and I didn't want to get into using an open camp fire approach which defeats the purpose and advantage of using a Rocket stove. I came across what is called a Coleman ovenon YouTube. A number of YouTube videos show a Coleman oven in operation on top of a Rocket stove. These videos persuaded me that a Coleman oven was a far better approach than using a Dutch oven for baking and I ordered one for $116 delivered.
On Friday I tested out the combination of the Coleman oven on top of the Rocket stove. I followed a YouTube tip and placed two bricks inside the bottom of the oven. The Coleman oven heated up to 230 C within 20 minutes of firing up the rocket stove and I cooked my Friday night pizza in the oven. I kept the oven going for one hour to see if I could maintain a stable temperature. The Coleman oven has a thermometer built into the front door and I used an additional probing thermometer placed in the vent at the top of the oven. The temperatures remained stable over one hour and it didn't take much additional firewood to maintain the temperatures.
The Coleman oven can collapse into a 300 mm x 300 mm x 75 mm using a very elegant concertina design. However, the Coleman oven isn't designed to lift and carry 2 brick on the bottom of the oven using the handle at the top of the oven. Yesterday I pop riveted the sides of the oven together into a permanent cube configuration. An excellent result.
My next experiment is to bake scones in my Coleman oven. I will then try baking bread in my Coleman oven after testing out a suitable bread recipe using hand milled flour in my Panasonic bread maker. I haven't yet got into sprouting grains or making my own rising mixture.

Modified copy of email to Seniors Climate Action Network (SCAN) - Bread Recipes & Pizza Oven
There is a lot for me learn about different bread recipes. I have used only one recipe so far in my Panasonic bread maker with a bit of tweaking. The basic ingredients are 2 cups of white flour, one cup of wholemeal flour, 3 teaspoons of Edmonds Surebake Active Yeast Mixture, one teaspoon of salt, 3 tablespoons of milk powder, and 3 tablespoons of Pams Salad & Cooking Oil. My personal tweaking is 5 grams of Thyme and 6 tablespoons of split pea and lentil mix.
For baking in a Dutch oven, I will be going for a simple recipe using the minimal number of ingredients - self milled flour flour, water, salt, and yeast. I like the idea of making one's own yeast. I have downloaded a number of simple recipes from YouTube. One recipe uses near boiling water to shorten the time before actual baking.
Sprouting is totally new to me and I like the idea of using long term storage peas, beans, and mung beans to make salad greens.
I don't think I will ever get around to building my own pizza oven. I can see the advantages of a community oven for baking bread and pizzas. It would be more efficient on fuel to bake many loaves of bread in one firing of a community oven. Use of a Dutch oven for baking bread etc. would be more efficient for baking at small scale for a single family. Another advantage of a Rocket Stove/Dutch oven combination is that it is portable. The total weight is 15 kilograms.
I will await for the arrival of my oven thermometer and probe thermometer before trying out simple bread recipes in Dutch oven on my stove top element first and then my Rocket Stove.
Before I forget, I have already checked out Harraways website for purchase of pre-milled oat grains. Yes, you can so long as you purchase in bulk by the tonne. A few weeks ago at Moana Pool I spoke to a staff member who works in the Harraways office and I queried him about buying processed porridge in bulk direct from Harraways. His reply was the company was considering it, but that option was not available at the moment.

Modified copy of email to Seniors Climate Action Network (SCAN) - Grain Sprouting & Rice Flour Bread
The following links should provide all the necessary information one needs to know about sprouting grains:
Mother Earth News website Nourished Kitchen website Bread Experience website YouTube Video
After reading and viewing the above web pages and YouTube video, I am keen to try out some sprouting, but first I need to purchase some wheat grain at a reasonable bulk price. I have bags of white and wholemeal flour at hand which will store for 6 months, but as yet no wheat grain which can store for years.
I have come across a large number of brown rice flour recipes which include starch based flour, but I haven't been able to find any recipe that uses only brown rice flour. I therefore carried out an experiment yesterday to find out if it was possible to bake bread using only brown rice flour. I used the same bread recipe that I have used for years in my Panasonic bread maker and substituted milled white and wholemeal flour with brown rice flour. The "dough" didn't rise even though I had used yeast and the mixture looked like porridge just before baking. The end result was edible, but not palatable - the "bread" was too heavy and dry.
This morning I did an Internet search to establish the cause of the failure of my experiment and I came across the answer in a scientific journal article - brown rice or white rice flour alone simply cannot make dough. The article continues to describe that a new method of wet milling overcomes the inability of dry milling of rice flour to form dough. At this stage I do not know whether it is possible to duplicate wet milling at home.
On another website I found out that one can make tortillas on a skillet using only rice flour and water. For the time being I have flagged away making brown rice flour bread and scones because the necessary ingredients to do so include starched flour. It is far easier for me to mill my own wheat grain flour and use simple recipes which include making my own yeast.
My next experiment will involve baking bread in a cast iron Dutch oven on top of my electric stove. I have ordered an oven thermometer for $7.60 delivered and a Probe thermometer for $13.84 delivered from Trademe. It is sensible to establish the ideal temperatures and time to bake bread in a Dutch oven on top of an electric stove first under controlled conditions before finding out how to set up the same conditions on a Rocket Stove. Maintaining a suitable hot flame in the Rocket Stove for up to an hour will in itself be a learning experience.
Under emergency conditions with the power down, breakfast is taken care of - first boil water in my Kelly Kettle and pour on my porridge and stir in a pot on my Rocket Stove. Lunch is taken care of by making brown rice tortillas or wheat grain flour based pikelets on a skillet over my Rocket Stove. I normally toast slices of my home made bread for lunch. In due course I will learn how to bake bread and scones in a Dutch oven on top of my Rocket Stove. For dinner - well, that is straight forward cooking in a cast iron skillet or Dutch oven over my Rocket Stove using baked beans and vegetables at hand and whatever else I have stored away. As an aside, tinned fish is half the price of tinned meat.
I like having desert at night, so I have a choice of cooking rice, sago, tapioca, and semolina. Tinned fruit helps with variety. The advice I get from City Prepping websites is to also stock up with non-essential food items to ensure variety in diet - jams, dried fruit, Marmite which I like, etc. etc. A supply of salt is essential. Don't forget vegetable oil.

Modified copy of email to Seniors Climate Action Network (SCAN) - City Prepping Continued
I am currently a novice when it comes to City Prepping, but I am motivated to learn much more and I will be carrying out experiments in baking bread and scones in a Dutch oven and pikelets in a skillet over my Rocket Stove using grain and rice that I mill. I have seen a reference to sprouting grains and I will look into this.
City Prepping is taking a survivalist stance to the future and to some people this is an extreme and pessimistic stance. I am not so sure this is the case. I think that City Prepping is tied up with resilience. We are currently locked into a just-in-time supply chain system of food production and distribution. This type of system is risky. We need to plan and organise by the seasons when it comes to food. Bottling fruit and jam may be considered by some to be old fashioned when we can buy the same products in the supermarket, but this activity is sensible. When our civilisation shifted from being hunter-gatherers to being an agricultural society, long term storage of food was a necessary component and activity. In the future we will all need to live by the seasons again and plan accordingly. Food supply will need to to be planned at a community level by an annual basis and not by a weekly expedition to the supermarket to replenish food supplies that have been totally consumed over the previous week.

My Power ADD Universal Solar Laptop Charger from Trademe ($131 delivered to Dunedin) does take a long time to charge using its small inbuilt PV panel. I have therefore purchased a 100 watt PV panel from Trademe for $160 delivered to make the system more practical. I have connected the PV panel directly into my Power ADD using an additional connection cable purchased from Amazon.com for $21 delivered. I first replaced and soldered the end plug for $2 to match the Power ADD. My laptop runs at 85 watts so, in theory, it is possible to plug my PV directly into my laptop. However, it is safer to charge up the Power ADD first because it has inbuilt safety features and then use the Power ADD to recharge the laptop.
I have tested out how long it takes to boil water using my Rocket Stove. When the fire is up and running it takes 8 minutes to boil 1.5 litres of water in my cast iron Dutch Oven which has a cast iron lid. It takes 4 minutes to boil 0.5 litres of water in a cold cast iron skillet and 3 minutes when the skillet has already been heated.
It is not a good idea to boil water in cast iron containers because doing so removes the vegetable oil baked on patina which protects against rusting. That is why I have purchased a 1.6 stainless steel litre Kelly Kettle from the UK for NZ $127 delivered. This kettle works on the same principle as the New Zealand manufactured Thermette Kettle which sells for more or less the same price delivered, except the Kelly Kettle is a better quality constructed kettle. The copper Thermette Kettle is very expensive. All these kettles are far more efficient at boiling water than boiling water over a fire in a container. I expect to be able to boil 1.6 litres of water in my Kelly Kettle within a few minutes.
For those who live on a gluten free diet and accordingly make their own bread, the following is not new to you. The food which contains the most carbohydrates and nutrition in the smallest volume of space and which have the longest shelf life are the grains before milling and rice. Brown rice can go rancid after 6 months, whereas white rice has a shelf life of a few years when stored in airtight containers. Wheat grain lasts for years in appropriate storage.
With regards to long term City Prepping food storage, a grain and rice mill grinder is essential. I have purchased a genuine Victoria Corn Mill made in Corona - not an inferior imitation - for NZ $123 delivered.
I have tested out milling 3 cups of brown rice (a typical number of cups of flour to bake a loaf of bread) and I have boiled the results mixed with water in my microwave. It takes two minutes to mill 3 cups of rice at the resistance setting that I feel comfortable with. Each successive milling of the same cups of rice by screwing the face plates closer together takes about 2 minutes at the same resistance and the number of times that one needs to mill the same cups of rice depends on whether you want to boil the rice as a breakfast food or desert or for baking scones and bread. To get the consistency of flour for baking a loaf of brown rice bread would require me to do 4 cycles of milling. Doing only one milling and boiling in water to an acceptable level requires 10 minutes in my microwave and using two cycles of milling requires only 5 minutes of boiling. The above experiment demonstrates and confirms for me that my Victoria Corn Mill is a practical way to enable use of long shelf life grains and rice. It is possible to use a battery powered drill to do the milling for you. My Power ADD can recharge 12 volt, 16 volt, and 19 volt batteries. I am not going to bother doing that as it is so easy to mill 3 cups of grains or rice.
My recent Internet search for bulk purchase of pre-milled grains demonstrated to me that buying from a health shop is an expensive option. If one doesn't shop around, then one will finish up paying for example many times more for wheat grain than milled flour. The same grains that are milled for purchase in the supermarkets are also used as animal feedstock. One can buy pre-milled grains in bulk at a reasonable price by making a visit to a number of mills in Ashburton or by talking to someone you know who has horses or pigs to find out their local source of feedstock or source which is prepared to deliver from another centre.

At Long Last an Opportunity for a Carbon Tax in New Zealand
On 23 September 2017 New Zealand held its three year term election and in the last few days the Labour Party, NZ First, and the NZ Green Party have been forming a new government. This is good news for current and future New Zealand citizens because the previous National Party government for 9 years has continually blocked and delayed action on Climate Change (see NZ News section on this website). At long last we have an opportunity to make progress on climate change action at government level.
In the Video section on this website I have identified three YouTube videos on the pros and cons of Carbon Taxes versus Cap and Trade (Emissions Trading Scheme ETS). After reading a number of publications on Carbon Tax and Cap and Trade (see below), these videos have reinforced for me that a Carbon Tax rather than an ETS is the way to go. An ETS is convoluted and overly complex whereas a Carbon Tax is straight forward and provides incentives for businesses and private citizens to reduce their direct and indirect use and reliance on carbon based fuels. The revenue collected from a carbon tax would be available by government to invest in sustainable energy systems and infrastructure and/or return to taxpayers.
The cost of solar collector PV panels has come down to about 10% of the cost 10 years ago, though solar storage batteries necessary for going off the grid are still very expensive. A much better way of storing solar energy for those close to the grid is to use our current hydro lakes for storage. Solar energy from PVs during the day can be fed back into the grid for use by electrified transport systems and industry thus reducing release of water through the hydro turbines.
Even though PVs have come down in cost, I suspect that most families in New Zealand would currently still baulk at buying even a low end 3.5 KW system which feeds back into the grid. This is where a carbon tax would help. The government could return collected carbon taxes to taxpayers by way of subsidies for the specific purpose of purchasing solar collectors or investment in other methods of reducing our carbon footprint and reliance on fossil fuels (electric bikes, group electric cars etc.). Targeting return of carbon taxes towards climate change action investments would be more effective than simply returning carbon taxes to taxpayers for subsequent discretionary spending. Investment by taxpayers in targeted investments would result in savings for each taxpayer - lower home electricity and transport costs. Taxpayers who do not have PVs which feed back into the grid would pay a higher charge for electricity.

If you missed the "Death by Design" movie on computer manufacturing and pollution screened on Aljazeera last night, then you will be able to view the movie over the Internet - Link here A description of the movie is as follows:
"Consumers love - and live on - their smartphones, tablets and laptops. A cascade of new devices pours endlessly into the market, promising even better communication, non-stop entertainment and instant information. The numbers are staggering.
The cell and smartphone industries have saturated the market; in 2015, it was estimated that 98 percent of all US citizens aged between 18 - 29 years owned a mobile phone. A staggering 86 percent owned smartphones. By 2020, four billion people will have a personal computer. Five billion will own a mobile phone.
But this revolution has a dark side, hidden from most consumers.
In an investigation that spans the globe, filmmaker Sue Williams investigates the underbelly of the electronics industry. What was uncovered tells an entirely different story to the falsified "clean industry" reputation promoted by the global electronics industry and the semi-conductor industry.
Even the smallest devices can have deadly environmental and health costs that are not only immediate but can span generations of workers who are still suffering the effects of a band-aid culture.
From the intensely secretive factories in China, to a ravaged New York community and the hi-tech corridors of Silicon Valley, the film tells a story of environmental degradation, of health tragedies, and the fast-approaching tipping point between consumerism and sustainability."

With regards to City Prepping for long term disruptions to our petrol, water, and electricity supply:
1. Shelter is taken care of - we keep living at home as usual.
2. Potable water is taken care of - a 250 litre tank ($145 from Bunnings) per person replenished by downpipe diverter from spouting ($30 plus additional piping).
3. Cooking is taken care of - Rocket Stove ($250 from Trademe) and Dutch Oven ($30 from Trademe).
4. Heating is taken care if one has a wood burner and a stock pile of timber. I have a wood burner in my lounge. My lounge ceiling is triple insulated and I have single insulation underfloor. The windows of my lounge are insulated in winter with polystyrene slabs ($60). I heat only one room at a time - the room I am in. Warm clothing is a sensible way to keep warm in winter at low cost. In winter I wear thermals, trail pants under my jeans, and two jerseys. If one doesn't have a wood burner, then a good investment for winter in Dunedin would be insulated trousers and overcoat.
5. Food in the medium term (2 months) is taken care of by stock piling what you normally use. Food supply is a problem in the long term if you don't already have a large veggie garden. This is where Community Gardens come in.
6. Transport is taken care of if you have a bicycle and are able to ride it.
As I have said before, it is possible to cope living in the city should there be a long term disruption to the supply of petrol, water, and electricity. It is a sufficient supply of food that is the main problem.
During a long term disruption to the supply of electricity, I want to continue using my tablet and laptop and to be able to recharge my mobile phone and emergency portable LED lights. This is where solar power comes in. I have purchased the Power ADD Universal Solar Laptop Charger from Trademe ($131 delivered to Dunedin):
The device can recharge a mobile a number of times without becoming fully discharged. According to reviews, the device cannot recharge itself from solar if it's charge goes below 50%. If this is the case and a 100% recharge of my laptop takes the charge level of the device below 50%, then I will invest in an additional 100 watt 19 Volt solar panel (about 1 square metre) to recharge the device. The additional PV will cost about $300. It is possible to run our computers on solar energy at a moderate low cost.
The cost of PVs have come down to about 10% of the cost 10 years ago, but solar storage batteries are still very expensive. A much better way of storing solar energy is to use our current hydro lakes. Solar energy from PVs during the day can be fed back into the grid for use by electrified transport systems and industry thus saving release of water through the hydro turbines. Even though PVs have come down in cost, I suspect that most families in New Zealand would still baulk at buying a low end 3.5 KW system which feeds back into the grid.

Great news on the formation of a Labour, NZ First, NZ Green Party Coalition Government. I have logged the global response on my website in the Global News section which includes NZ Herald's Headline from Mike Hosking. At long last we can make progress on climate change action at government level.
My website includes recommended books on Transition in the Recommended Books section. The best book that I have come across on Transition is
"Earth at a Crossroads: Paths to a Sustainable Future" by Hartmut Bossel, 1998 - Amazon.com link here
Unlike many authors of popular books on the subject who findings are based on an amalgam of other people's primary and far too frequently secondary research, Emeritus Professor Hartmut Bossel is a scientist and researcher in systems dynamics which is key to combining all issues of sustainability. The book is a delight to read. I own four of his more technical books which I also rank as being among the best written on systems dynamics.
Too many books on transition are overly optimistic as to what is possible and overlook the scale and time required for transition. When these factors are taken into consideration, I finish up being an optimistic pessimist hence why I feel the need for long term City Prepping. If one of a number of serious worst case scenarios should occur here in Dunedin - for example a long and protracted disruption to our supply of petrol - then I am sure that long term City Prepping will see us through. However, the most serious long term City Prepping issue is that of ensuring food supplies. That is why Community Gardens are so important.

Thank you for the link. Much appreciated. Robbie Andrew has done some very interesting work on climate change. I see that his research profile is on the University of Oslo website and yet he works for CICERO, Center for International Climate Research, which is an institute based in Norway. This institute seems to be independent of the University of Oslo, so perhaps Robbie Andrew is a part-time or honorary lecturer at the University of Oslo. Tomorrow I will add Robbie Andrew to my list of researchers on my website and CICERO to my list of global research organisations.
There is certainly no dearth of information over the Internet. So far I have collected far more information than I can possibly process, but I am still adding links links to websites that I find to be especially interesting and informative which others may be able to make better use of than I can.
I think my days of doing original research are over. It involves too much brain strain and requires too much specialisation for my taste in order to add to the pool of knowledge.
My current role, if any, is to focus on educating the general public by way of e-learning courses and educational video. This also involves brain strain. Developing the Climate Reality Project video was a breeze to do with a ready made script and slides at hand. As an aside, I note that the Wise Response submission refers to the need for life cycle costing. I have a Cost in Use / Annual Equivalent Calculator for download on my website.
Creating good visual slides is time consuming. In the last few weeks I have been processing such slides into a common 1920 x 1080 pixel format with permission to do so by the creators of a number of PowerPoint presentations. Most of these presentations slides are a visual overload. Simplification is sorely needed. The advantage of using the software Camtasia Studio is that I can zoom in on sections of slides and highlight points of interest. With Articulate Storyline I can structure an e-learning course so that a viewer can navigate at their own pace. With Camtasia Studio even a movie over the Internet can be navigated by a viewer at their own pace. This is not possible with a YouTube movie, hence why I have my own website instead of using WordPress or relying on YouTube.

Thanks for the Wise Response submission. The contents of a large part of the submission look familiar and I have at hand many of the cited publications and similar publications.
I signed the Wise Response petition some time ago. After reading the final submission I am pleased to find that it echoes very closely my own sentiments and conclusions. Clauses which struck a special chord for me in terms of needed action and change were #165, #178, #181, #193, and #194.
I have joined Wise Response as a member. Membership is free which is not always the case. Some time ago I came across a New Zealand research organisation which required a hefty annual membership fee. My gut feelings were that the organisation was pandering to vanity membership rather than genuinely trying to bring about change. On my own website I have avoided links to other websites which have the prime purpose of generating income (apart from Amazon.com links for recommended books). We all need to pull together and provide our services for free

In the above series or possibly another YouTube video, I came across what is called a Rocket Stove which is ideal for cooking and boiling water. An Internet search of its availability in New Zealand came up with a supplier on Trademe as follows:
Challenge Yachts Ltd $227.82 plus $21.85 courier to Dunedin. I have made my purchase.
The above exercise prompted me to also buy a 250 litre water tank from Bunnings for $215 complete with water collector/diverter from roof and 1 metre hose and fittings even though I have at hand three 10 litre water containers and a water tank system in my roof space. The cost per litre of storage of the Bunnings water tank is a bargain and the water tank is easily connected to a downpipe. We all need a minimum of 2 litres of drinking water per day, so 250 litres will do the job for a few months between rainfall. I will immediately fill my tank with tap water.

I am also very disappointed about the election results and I am in a process of regrouping and pondering what is the best action of response one can undertake. I keep coming back to education and the need to combat deliberate misinformation.
Thanks for passing on the links. Much appreciated. I am most impressed by the first link that I am currently processing - namely Rob Mielcarski's "Un-Denial' Blog - Link here

I have identified 3 very useful YouTube videos on the pros and cons of Carbon Taxes versus Cap and Trade (ETS) which I have now listed on my website under the video section.
In my search for decent presentations on these issues, I found it striking that there was a preponderance of almost troll like video opposition to carbon taxes. The above videos provide a more balanced review of the pros and cons.

The first 30 minutes or so of the following presentation (59 minutes) is a must see.
'Clear Price Signals in the NZ ETS' by Motu: Economic and Public Policy Research - Link here
The first 30 minutes or so is presented by Suzi Kerr, Senior Fellow of Motu. I found the content of the first 30 minutes or so to be very informative and well presented. It covers history of where NZ has been, where we are at currently, and where we need to go. Suzi Kerr would be an excellent presenter for our workshop.
The second 30 minutes is a presentation by Catherine Leining on Motu's Emission Treading Scheme for New Zealand. This presentation reinforced for me that a Carbon Tax rather than an ETS is the way to go. An ETS is convoluted and overly complex. A Carbon Tax is straight forward and provides incentives for businesses and private citizens to reduced their direct use and reliance on carbon based fuels and indirect use of processes and products based on fossil fuels. The revenue collected from the carbon tax would be available by government to invest in solar based energy systems and infrastructure.
If New Zealand is unable to meets it's obligations to the Paris Agreement, then it could purchase ETS units from a less developed country which has greater opportunity to reduce its emissions by avoiding a fossil fuel based infrastructure and upgrading directly to a solar based economy. In other words, the penalties imposed by the Paris Agreement encourages richer countries to assist less developed countries to meet their targets. It is a win-win situation.

Today I decided to track down publications on Risk, Uncertainty, and the Precautionary Principle and also on Discounting and Inter-generational Equity. In doing so I came across the publication "An Updated Assessment of Oil Market Disruption Risk" published by the Energy Modeling Forum, Stanford University 2016. The publication is quite sobering. The same information on a blog site might be regarded by some as scaremongering. The publication can be downloaded here and a summary of the publication can be downloaded here
Last night I watched the recorded documentary on TV3 by Bryan Bruce "Who Owns New Zealand Now?" This documentary will no doubt eventually find itself onto YouTube. I have come across two other documentaries by Bryan Bruce on YouTube as follows:
‘Mind the Gap’ - YouTube link here and ‘Child Poverty in New Zealand’ - YouTube link here
In a similar vein, another documentary, ‘Someone Else's Country’ - YouTube link here

New Zealand Minister of Energy & Resources Clanger in Question Time
I have been following the New Zealand Parliament Question Time for some years now and the following clanger by Judith Collins, Minister of Energy and Resources, in response to questions by Julie Anne Genter, Green Party Member of Parliament has prompted me to save the video and transcript of this 16th August 2017 exchange. The video can be seen on the YouTube link here
Judith Collins justified continued oil and gas exploration in New Zealand because “the International Energy Agency forecasts that oil and natural gas will account for almost half of the world’s needs until at least 2040”. At the end of her questions Julie Anne Genter sought to “leave a table of an analysis that 80% of all existing coal and gas fossil fuels in the ground cannot be burnt.” It is a shame that the format of Question Time does not allow a proper debate which would more clearly demonstrate to the New Zealand public the full extent of Judith Collins’s fallacious justification. If all nations were to burn more than 20% of the current known reserves of fossil fuels, then they would be abrogating their responsibilities to curb greenhouse gas emissions and escalate the extent of climate change. A primary international refereed journal publication that addresses this issue is listed below followed by websites and a 2015 article in The Guardian.

An Example of the Folly of Wishful Thinking
Have a look at the New Zealand Pure Advantage website and its About page - link here
Comprised of business leaders who believe the private sector has an important role to play in creating a greener, wealthier New Zealand, Pure Advantage is a not-for-profit that investigates and promotes opportunities for green growth.
Against a gathering storm of population, climate and resource pressures, sustainable living has become an urgent challenge for everyone.
There is, however, a silver lining to this cloud – a growing awareness that environmental sustainability and economic growth are not mutually exclusive, and that significant opportunities await those who meet the challenge with speed, creativity and firmness of purpose.” (My highlighting)
The First Law of Sustainability
Population growth and/or the growth in the rates of consumption of resources CANNOT BE SUSTAINED!
Economic growth cannot be sustained because growth of the economy (growth in economic activity) cannot be totally decoupled from growth in the consumption of resources.
Have a look at Richard Heinberg’s publication “There’s No App for That” which can be downloaded for free from the link here
One of Richard Heinberg’s major conclusions on pages 51 and 52 advocates that the environmental movement should return to first principles in order to become more effective. The Pure Advantage website and its underlying philosophy is an example of why the genuine environmental movement needs to return to First Principles so as to oppose the folly of wishful thinking.

Earth Overshoot Day
Today is Earth Overshoot Day, the day in this year of 2017 when we have already used more from nature than our planet can renew in the whole year. Have a look at France’s Minister of the Ecological Transition addressing his nation on Earth Overshoot Day (YouTube link here with English subtitles). His statement and commitment to addressing Climate Change makes a striking contrast to our own New Zealand Minister for the Environment. Our independent Parliamentary Commissioner for the Environment, Dr Jan Wright, has issued a rallying call to to all Members of all parties in the New Zealand Parliament to come together to tackle climate change. Dr Wright has recommended “... a new Act that is similar to the UK Climate Change Act. This is a law that was passed with overwhelming cross-party support in the House of Commons in 2008. At least nine other countries have since passed similar legislation, including Denmark, Finland, France, Ireland, Mexico, Norway, Scotland, Sweden, and Switzerland.” New Zealand is currently lagging far behind in terms of serious comittment to addressing Climate Change. Dr Wright’s publication ‘Stepping stones to Paris and beyond: Climate change, progress, and predictability’ can be downloaded here

World Population Day
The issue of population growth is the elephant in the room which many people ignore. If we want to address the issue of climate change by reducing our CO2 and equivalent contributions to the atmosphere, then it is the product of the number of people on planet Earth and their individual consumption rates of fossil fuels etc. that impacts on our climate. To ignore population growth will forestall the best of our intentions to address climate change.
In the 1970s my wife and I took the Zero Population Growth cornerstone of sustainability very seriously and we subsequently restricted our family size to two children. We were lucky – we had a daughter and then a son. Some 40 years later the right to have as many kids as you want in New Zealand is still regarded as being sacrosanct. Even in more enlightened sustainability circles, I have encountered people who have been offended when I point out that one of the most effective ways of reducing our ecological footprint is to restrict the size of our families. For example, see the following publications and YouTube video:
‘Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming’ edited by Paul Hawken - Amazon.com link here
‘The Climate Mitigation Gap: Education and Government Recommendations Miss the Most Effective Individual Actions’ by Seth Wynes and Kimberley Nicholas published in the Journal Environmental Research letters 2017 - download link here
‘Sustainability 101: Exponential Growth - Arithmetic, Population and Energy (Full - Updated)’ - Al Bartlett - YouTube link here
To suggest that all countries, including under developed countries, should restrict population growth by reducing the size of families is regarded as being politically incorrect. Common responses to a call to curb population growth include accusations of right-wing fascist coercion and a knee jerk assumption that the call to curb population growth is based on the politics of eugenics. Along with rights come responsibilities. We all have a responsibility to our current and future generations to leave our planet Earth in a no less worse state than when we were born into it. Education, and not coercion, is the key to families deciding for themselves to restrict the number of children they have. Families in underdeveloped countries need assistance from richer countries to both improve their standard of living, level of education, and to make a transition to a sustainable economy.

A realistic Approach to Future Urban Transport
This is a realistic approach to future urban transport compared to putting electric motors and batteries into the same old, same old, 5 seater, bulky and heavy car for urban commuting with no passengers. I just can’t wait to buy one to replace my 1994 670 cc three cylinder Suzuki Alto. It will get me over the hill from Green Island to the city, keep me protected in all inclement weather, store my groceries in the back, and feel more safe than riding an electric bike or electric scooter in traffic. Focus should be on this type of approach and technology than on the misdirected same old, same old, driverless cars.

Climate Change and Peak Oil: What Now?
With regards to climate change and peak oil, I am an optimistic pessimist. I want there to be and hope for a smooth and peaceful transition to a stable steady state economy for all nations with greater equity between and within all countries. However, given the multiplicity of information and data from diverse and what seem to be the most reliable sources of information, I fear that the future before 2050 will be strife for millions around the globe. Society has ignored warning signals about both climate change and peak oil over the past 40 years and tends to respond only to emergencies. I suspect that even now insufficient action will be taken in New Zealand and other countries to address the issues of climate change and peak oil. If so, then ensuing problems and strife will continue to multiply and escalate. In the extreme, there could be a Third World War where nuclear weapons are used.
New Zealand is naturally endowed with hydro and geothermal resources and is currently able to generate 80% of its total electricity demand using these renewables including wind power. So long as current global strife does not degenerate into World War III, New Zealanders should fare OK in the long term on a lower than current total energy consumption per capita using solely renewable energy based electricity generation. Hopefully we will add sufficiently more renewable energy based electricity generation, but there are likely to be teething pains on the way. In order to retain a national rather than a village society, we need to invest now rather than later in the necessary infrastructure for an electricity based railway system linking cities otherwise each and every town and city will need to achieve greater self-sufficiency. Multiple duplication of manufacturing in each town and city would result in a greater cost for each town and city. If the additional costs cannot be met, then the consequences would be a much simpler lifestyle than what we could achieve otherwise. The same applies in terms of renewable based energy transport systems between countries and self sufficiency within each country. For example, are we able to manufacture computers in New Zealand without importing necessary components? If not, then what form of renewable energy will be used in the future for transport of desirable if not essential components and resources between countries? Provision of transport between countries using only renewable energy is far more problematic than providing electricity based transport systems linking cities within a country.
The Comalco aluminium smelter at Tiwai point in Bluff currently uses 13% of New Zealand’s total electricity generation. A related decision to New Zealand investing in an electricity based transportation system linking cities is the decision of when and whether to scrap Comalco entirely or to downgrade the level of production of aluminium for domestic use only. New Zealand currently uses non-renewable energy to generate 20% of its total electricity. The argument that aluminium can be produced more efficiently here in New Zealand than in another country because its production uses solely renewable energy sources doesn’t hold water because New Zealand doesn’t have a surplus of hydro and geothermal energy that can be earmarked as being used by Comalco. The energy currently used by Comalco could be diverted to use by an electric railway system linking cities which would in turn enable a reduction and eventual elimination of fossil fuels currently used by trucks transporting goods between cities.
The question as to what are the true benefits and costs of continuing to supply Comalco with electricity needs to be addressed and debated, especially given New Zealand’s commitment to the Kyoto Protocol and the more recent Paris Agreement. Do the benefits of employment for New Zealanders working at Comalco outweigh the costs of using non-renewable energy that is needed in order to match the total electricity demands of New Zealand? It may be that the benefits of employment currently do outweigh the costs, but this cannot continue forever under conditions of peak oil where not only the rate of energy supply continually declines and can no longer match the previous rate of demand at the peak, but the Energy Return on Energy Invested (EROI) also continually declines, a double whammy. The true benefits and costs of continuing to supply Comalco with electricity need to be established and monitored on a regular basis and appropriate decisions need to be made.
One other hope I have is that New Zealand does not degenerate into a totalitarian society should problems ensuing from climate change and peak oil multiply and escalate. It dismays me when one third of our voting population do not vote at national elections. It would be a disaster if discontent of voters in New Zealand should result in a majority support of a demagogue by default. Everyone entitled to vote in New Zealand should vote so as to ensure that we maintain a democracy.

An Example of Misinformation and Propagation Over the Internet
The website https://archive.org/details/Ecoscience_17 provides the following synopsis of the book "Ecoscience" which is listed as being authored by John P. Holdren:
"In [sic]1977 book, John Holdren advocated forced abortions, mass sterilization through food and water supply and mandatory bodily implants to prevent pregnancies"
The book ‘Ecoscience: Population, Resources, Environment’ was first published in 1970. I purchased the 1977 publication in 1978. From memory the book did not advocate “forced abortions, mass sterilization through food and water supply and mandatory bodily implants to prevent pregnancies." To double check this, I downloaded the PDF version of the book and did a search of the keywords "abortion", "sterilization", and "pregnancy". The book provides comprehensive and detailed histories of birth control, abortion, and sterilisation that have been carried out in various countries. The book does not advocate “forced abortions, mass sterilization through food and water supply and mandatory bodily implants to prevent pregnancies." Instead, the book addresses the serious issue of over population growth and advocates the ultimate need for zero population growth by way of voluntary birth control because any form of growth cannot continue forever.
The 1977 publication of Ecoscience was co-authored by Paul R. Ehrlich, Anne H. Ehrlich, and John P. Holdren. In 1977 Paul Ehrlich was a Professor of Population Studies at Stanford University, Ann Ehrlich was a Senior Research Associate in Biological Sciences at Stanford University, and John Holdren was an Associate Professor of Energy and Resources at the University of California. Paul Ehrlich wrote the chapters on population which addressed birth control and not John Holdren. The claim "John Holdren advocated forced abortions, mass sterilization through food and water supply and mandatory bodily implants to prevent pregnancies" is incorrect and libelous.
The above website invites readers to write book reviews and claims that reviews would be vetted before being posted on the website. I wrote more or less the same text as the above blog finishing with advice to remove the libelous statement. To my surprise my advice was posted as a book review. The above website is an example of how lack of proper vetting and double checking of information content can not only lead to propagation of misinformation over the Internet, but also a continuation of misinformation.
A PDF copy of the above website page as of 19 February 2017 which includes my “book review” can be downloaded here

Oil Exploration in New Zealand Waters
According to the New Zealand Greenpeace website : "The word's biggest seismic blasting ship - known as 'The Beast' - is exploring for oil in the seas between Kaikoura and Napier. Despite the climate crisis, the risk of catastrophic oil spills and the immediate harm done to marine life, Statoil and Chevron are exploring for new oil at the invitation of the NZ Government".
The New Zealand government does not understand or ignores that in order to avoid climate change above 2 degrees, 80% of current known oil reserves must stay in the ground. Carbon Tracker warns that fossil fuel firms risk wasting $2 trillion on uneconomic projects in the next decade if they pursue business as usual strategies. A COP21 Carbon Asset Risk conference was held in 2015. In a Youtube video of one of the proceedings, fund managers of major pension funds demonstrate 57 minutes 53 seconds into the video that they are well aware of Carbon Asset Risk and have subsequently disinvested in the fossil fuel sector. It is shameful when a government charged with acting on behalf of the Public Good lags behind the private sector.
