In November 2010, Professor Ross Garnaut was commissioned by the Australian Government to provide an independent update to his 2008 Climate Change Review. He is also an independent expert adviser to the Multi-Party Climate Change Committee. The Garnaut Climate Change Review – Update 2011 will release a series of papers in early 2011 and present its final report to the Australian Government by 31 May 2011.
The purpose of the Garnaut Climate Change Review – Update 2011 (the Update) is to provide an overview of developments in key areas such as international policy, climate science, emissions trends, policy instruments (i.e., a price on carbon) and technology since the initial 2008 Climate Change Review. The Update will be comprised of eight papers:
- Weighing the costs and benefits of climate change action
- Progress towards effective global action on climate change
- Global emissions trends
- Transforming rural land use
- The science of climate change
- Carbon pricing and reducing Australia’s emissions
- Low emissions technology and the innovation challenge
- Transforming the electricity sector
So far, the first three papers have been released on February 3, 7, and 11. The fourth paper is due on March 11.
The first update paper “Weighing the costs and benefits of climate change action” finds that:
- the Review’s choice of discount rate was sound and that the Australian case for climate change action is not affected by reasonable variations in the approach to choosing a discount rate;
- the presence of uncertainty in the range of possible climate outcomes strengthens the case for climate change action;
- the Review’s approach to the treatment of developing countries as part of a global response remains a robust and ethical basis for a long-term solution;
- the case for substantial and well-designed Australian action to encourage international agreement on climate responses remains compelling; and
- while the current and prospective realities of damage from climate change warrant effective efforts on adaptation, this does not weaken the case for strong focus on mitigation.
This is nothing new and should not come as a surprise. The proposition that the (economic) risks of inaction in the face of climate change are very severe, and that action, adatation to and mitigation of climate change, is worthwhile and likely to reduce these risks has already been strongly advocated, not only by the IPCC, but also by Stern in his Review on the Economics of Climate Change in October 2006 – 4.5 years ago. Of course there has been a lot of debate and criticism around the discount rate, but one might argue that what constitutes the “optimal” discount rate lies in the eye of the beholder. Stern and his team have released responses to the criticism in 2007 and 2008.
The case for strong and urgent action set out in the Review is based, first, on the severe risks that the science now identifies (together with the additional uncertainties [...] that it points to but that are difficult to quantify) and, second, on the ethics of the responsibilities of existing generations in relation to succeeding generations. It is these two things that are crucial: risk and ethics. Different commentators may vary in their emphasis, but it is the two together that are crucial. Jettison either one and you will have a much reduced programme for action—and if you judge risks to be small and attach little significance to future generations you will not regard global warming as a problem. It is surprising that the earlier economic literature on climate change did not give risk and ethics the attention they so clearly deserve, and it is because we chose to make them central and explicit that we think we were right for the right reasons.
It should be obvious that the risks posed by climate change raise a set of significant issues that go far beyond those related to discounting.
The second paper’s (“Progress towards effective global action on climate change“) key points are:
- The 2008 Garnaut Climate Change Review said that strong mitigation, consistent with Australia’s national interest, requires effective global action, with Australia playing its proportionate part. Effective global action requires comprehensive agreement among countries.
- The Copenhagen meeting in December 2009 and the Cancun meeting in December 2010 moved the world towards several elements of such agreement, but away from one important element.
- The reality of considerable positive movement is obscured by the diplomatic fiasco at Copenhagen, which was rescued from comprehensive failure by the President of the United States reaching an understanding with leaders of China, India, Brazil and South Africa during the meeting itself.
- The Copenhagen and Cancun meetings have led us into a messy world in relation to the setting of each country’s ambitions on emissions reductions. But they have embodied strong progress on several crucial and difficult issues, and may have laid a basis eventually for the comprehensive and binding international agreement that is still necessary to avoid high risks of dangerous climate change.
- Most developed countries—members of the European Union, Japan, New Zealand and now Korea—are reasonably well placed to make full contributions to achieving strong global mitigation goals.
- Major developing countries seemed to be sources of weakness at the time of the Review, but are now making large emissions reductions below business as usual. Chinese climate change policy is at the centre of the international effort to reach global agreement, because it is the world’s largest source of greenhouse gas emissions, because it is by far the largest prospective source of emissions growth, and because economic and strategic competition between China and the United States is important in the policy dynamics of both countries.
- The three countries which have been the largest drags on the global mitigation effort are the three highest per capita emitters amongst the developed countries—Australia, Canada and the United States.
- The United States faces large domestic constraints on early action, but is still committed to a significant reduction in emissions. It is also benefiting from favourable developments, such as the ‘gas revolution’, in its efforts to reduce emissions.
- The United States commitment is supported by substantial government support for low-emissions technologies; by extension of regulatory oversight of energy efficiency and emissions standards by Federal agencies; and by many state-based initiatives to establish ETSs and emissions-reducing regulations.
- If Australia were to introduce a carbon price, one that was seen as commensurate with carbon prices in other countries, it would cease to be a drag on international mitigation. Australian success in introducing a carbon price is likely to assist the United States and Canada to maintain momentum in policies to reduce emissions.
- Australia could also exercise global leadership in the mitigation effort without making unrealistic demands on community support for action, by implementing efficient means of reducing emissions through policy innovation.
Probaby most interesting is the the reference to Australia being a drag on international mitigation. A statement that is certainly justified. Australia has committed to an uncoditional greenhouse gas reduction target of 5% below 2000 level by 2020. There is now disagreement (again) about the appropriateness of such a weak target. As discussed in a previous post, not only is a 5% (15% if there is global agreement) reduction by 2020 is unlikely to unleash the technological innovation and commitment that is necessary to shift towards a low carbon economy, but it is also well below those recommended by the IPCC and the Garnaut Review. In fact, GHG reductions of 5-15% are equivalent to a stabilisation at about 510-550ppm, not the 450ppm the Australian Government is lobbying for.
The question is whether taking the same level of commitment to Cancun that was demonstrated in Copenhagen and Poznan was actually going to be the catalyst for change both domestically as well as for international negotiations. Already in 2008, Australia’s targets have been deemed insuficcient. Australia has repeatedly voiced a desire to take a leaderhsip role in tackling climate change, but a 5% target and the lack of a clear climate change policy fall extremely short of a leadership role. Now with a number of trade partners discussing the implementation of emission trading schemes and/or carbon taxes (despite recent delays in Japan and South Korea), Australia really need no longer fear of “going it alone“. The EU has an emissions trading scheme (with some member states also having in place various carbon taxes), so does New Zealand, there are two regional emissions trading schemes in place in the US – despite their stance during international climate negotiations – with a third one about to be launched (RGGI, MGGRA, and the WCI), India has a carbon tax on coal, and China is investigating the option of a cap-and-trade scheme to redcue emissions. The time has come for serious commitment and action. These countries and companies operating there are already gaining valuable experience and expertise in dealing with a price on carbon.
While emissions of greenhouse gases in the EU ETS fell 11.6 % in 2009 compared with a 2008, Australia is still debating the best approach to a price on carbon, despite previous findings and recommendations. Again, the Update findings are neither new now particulalry surprising. The biggest contribution of this update paper probably is the summary of the outcome of recent COPs.
The update on “Global emission trends” comes to the following conclusions:
- Without mitigation, and in the absence of negative feedback from climate change, global emissions will double between 2005 and 2030. This updated business as usual projection is in line with the projections of the 2008 Review.
- The shift in global growth momentum towards developing countries discussed in the 2008 Review has become more pronounced.
- Developing countries are now projected to account for 70 per cent of global emissions at 2030 under business as usual, compared with the Review’s projection of 63 per cent.
- China and India are growing strongly, and other developing countries are also experiencing an acceleration of growth that began in the early twenty first century.
- China is heading towards developed country income levels even more rapidly than anticipated in the 2008 Review, and therefore will need to accept developed country emissions constraints at an earlier date, if global objectives are to be met.
- China’s Copenhagen mitigation commitments to 2020 are stronger than anticipated by the 2008 Review, providing a platform for what will subsequently be required.
- The Great Crash of 2008 has pushed the developed countries of the northern hemisphere onto a lower long-term economic growth trajectory. This and other factors will result in lower underlying emissions growth in developed countries, but is fully offset by stronger emissions growth in the developing world.
- There has been a large recent expansion of known gas reserves that has reduced the relative price of gas and which may provide significant opportunity for reductions in business as usual emissions over the next decade beyond what is anticipated in these projections.
- Australia is unique among the developed countries: its business as usual emissions are set to grow considerably.
- Growth in projected business-as-usual emissions is primarily due to expected strength in the resources sector in the years ahead.
- The Department of Climate Change and Energy Efficiency estimates that Australia’s emissions are projected to rise by 24 per cent above 2000 levels by 2020, under current policies (which are below ‘business as usual’).
- Mitigation efforts in higher income developing countries will need to be stronger earlier, and other developing countries will need to be brought within emissions constraints sooner than once may have seemed necessary.
- This is unlikely to be possible without an acceleration of mitigation effort in the developed countries. Achieving a given abatement target has become easier in most developed countries, given lower growth prospects.
Once again, the Update does not really provide any new or previously unknown facts. The need for early and drastic cuts in greenhouse gas emissions in order to prevent a dangerous runway effect of unmitigated climate change has been highlighted in reports such as the Stern Review (2006), the IPCC (2007), the 2008 Garnaut Review, the 2009 Climate Change Congress’ Synthesis Report, UNEP’s 2009 Climate Change Science Compendium, and the 2010 Emissions Gap Report. Data on global emissions and trends can be found at the UNFCCC’s website.
However, what is interesting are the latest emissions projections by the Department of Climate Change and Energy Efficiency. Emissions in Australia are projected to increase 24% above current levels without “decisive and effective new policy action”. Obviously, Mr Combet blames Tony Abbott and the Opposition for the very slow progress (or complete lack thereof). However, it must be said that the Government itself has not done that much either other than going through the same debate over and over again. While according to Mr Combet not all is lost, one has to remember the insufficient commitment made by Australia so far.

In summary, the Update does not really provide any new information or knowledge. It is rather an agglomeration of already available reports, research and information. Just like the initial 2008 Garnaut Review seems to be more of an Australian Version of the 2007 IPPC’s Fourth Assessment Report, the Update, too, conveys the impression that while the information was/is already available, it was not compiled by an Australian. One has to think of the time and money being spent for this exercise. Rather than implementing policies based on exisiting knowledge now, the wheel is being reinvented. The final report of the Update is not due until the end of May 2011, which certainly will be followed by much discussion and debate (again) about the validity, assumptions, projections, if not the science per se. Then there is the Multi-Party Climate Change Commission, which will meet monthly until the end of 2011. Action is not to be expected before next year. And by then, a new update is probably required.
Once again, I would like to cite Yvo de Boer, Executive Secretary of the United Nations Framework Convention on Climate Change from 4 September 2006 to 1 July 2010:
The perfect is the enemy of the good.
Australia has to commit to something, get action started. The EU ETS was not perfect, it still is not, but at least it is a start, and it seems to be working rather well.
