Canada’s Step Away From the Kyoto Protocol Can Be a Constructive Step Forward

Canada confirmed this week that it will not take on a target under an extension of the Kyoto Protocol following the completion of the first commitment period, 2008-2012.  Given that Canada is likely to miss by a wide margin its current target under the first commitment period, this decision may not be surprising, but it is nevertheless important.  More striking, it may actually turn out to be a positive and constructive step forward in the drive to address global climate change through meaningful international cooperation.  Why do I say that?

The Current Situation

The Kyoto Protocol, which essentially expires at the end of 2012, divides the world into two competing economic camps.  Emission reductions are required for only the small set of “Annex I countries” (essentially those nations that used to be thought of as comprising the industrialized world).  Such reductions will not reduce global emissions, and whatever is achieved would be at excessive cost, because of having left so many countries and so many low-cost emissions-reduction opportunities off the table.  Furthermore, that dichotomous distinction is by no means fair:  more than 50 non-Annex I countries now have higher per capita incomes than the poorest of the Annex I countries.  (I have written about this and other issues surrounding the Kyoto Protocol in the past:  Defining Success for Climate Negotiations in Cancun; Defining Success for Climate Negotiations in Copenhagen; Three Pillars of a New Climate Pact).

The United States did not ratify the Kyoto Protocol, and has made it clear that it will not take on a target under a second commitment period.  The U.S. position continues to be that a considerably broader agreement is necessary – one that includes commitments not only from the Annex I (industrialized) countries, but also from the key emerging economies, such as China, India, Brazil, Korea, Mexico, and South Africa.

For much the same reason, Russia and Japan announced last year that they would not take on post-2012 commitments under the Kyoto Protocol.  Further, it is unlikely that Australia will take on such a commitment under Kyoto, essentially leaving the European Union on its own.

On the other hand, the Kyoto Protocol is enthusiastically embraced by the non-Annex I countries (sometimes inaccurately characterized as the “developing countries”), because it holds out the promise of emissions reductions by the wealthiest nations without any responsibilities (costs) borne by others, including the emerging economies.

The Path from Copenhagen to Cancun to Durban

Year after year, the Conference of the Parties to the United Nations Framework Convention on Climate Change has failed to reach agreement on a second commitment period for the Kyoto Protocol.  Most recently, in December, 2010, the issue was punted from the annual conference held in Cancun, Mexico, to the next conference, scheduled for December, 2011, in Durban, South Africa.

Because Durban provides the last opportunity to set up post-2012 targets (with time remaining for national ratification actions), it has been anticipated that the negotiations in Durban will re-ignite the divisiveness and recriminations that highlighted the Copenhagen negotiations in 2009 – with verbal hostilities between Annex I countries and non-Annex I countries dominating the discussions at the expense of any other considerations or meaningful actions.

A Positive and Constructive Step Forward

 

The decision just announced at meetings in Bonn, Germany, by the Canadian delegation that Canada will not take on a target in a second commitment period of the Kyoto Protocol can be a very constructive step forward.  This is because it greatly reduces the risk that this year’s annual meeting of the Conference of the Parties in Durban will be dominated by acrimonious debates about a second commitment period for the Kyoto Protocol.

On the contrary, this announcement should encourage the non-Annex I (“developing”) countries, which have been insisting on a second commitment period, to begin to accept the reality that with the United States, Japan, Russia, and now Canada on record as not endorsing a second commitment period for the Kyoto Protocol, it is infeasible for the European Union to go it alone.  (Indeed, one might suspect that Australia and most European nations are privately pleased by Canada’s announcement.)

The reality is that the world will be better off by focusing on sensible alternatives under the Long-Term Cooperative Action track of the UN negotiations and by “getting real” about post-Kyoto international climate policy architecture for the long term, such as by putting some additional meat on the Cancun Agreements and by considering any supplemental and sensible architectures the various parties wish to discuss.  (For previous posts on the Cancun Agreements, see:  Why Cancun Trumped Copenhagen; What Happened (and Why):  An Assessment of the Cancun Agreements; Defining Success for Climate Negotiations in Cancun.  For descriptions of a wide range of potential global climate policy architectures — ranging from top-down to bottom-up — see the diverse publications of the Harvard Project on Climate Agreements.)

Next Steps

At Cancun, it was encouraging to hear fewer people holding out for a commitment to another phase of the Kyoto Protocol, but it was politically impossible to spike the idea of extending the Kyoto agreement entirely.  Instead, it was punted to the next gathering in Durban.  Otherwise, the Cancun meeting could have collapsed amid acrimony and recriminations reminiscent of Copenhagen.

Usefully, the Cancun Agreements recognize directly and explicitly two key principles:  (1) all countries must recognize their historic emissions (read, the industrialized world); and (2) all countries are responsible for their future emissions (think of those with fast-growing emerging economies).  In important ways, this helps move beyond the old Kyoto divide.

The acceptance of the Cancun Agreements last December suggested that the international community may have begun to recognize that incremental steps in the right direction are better than acrimonious debates over unachievable targets.  Canada’s announcement should help advance that recognition, and can thereby lead to vastly more productive talks this year in Durban.

A Wave of the Future: International Linkage of National Climate Change Policies

The latest rage in Washington policy discussions these days (that’s relevant to climate change) is renewed interest in renewable electricity standards, this time in the form of so-called “clean energy standards.”  I’ve written about this policy approach recently at this blog (Renewable Energy Standards: Less Effective, More Costly, but Politically Preferred to Cap-and-Trade?, January 11, 2011), and will do so again in the near future, but for today I want to turn to an important issue – for the long term – on the related topic of the international dimensions of climate change policy.

The Current State of Affairs

Despite the death in the U.S. Senate last year of serious consideration of an economy-wide cap-and-trade system for carbon dioxide (CO2) emissions – and the apparent political hiatus of such consideration at least until after the November 2012 elections – a major cap-and-trade system for greenhouse gas (GHG) emissions is in place in the European Union; similar systems are in place or under development in New Zealand, California, and several Canadian provinces; systems are being considered at the national level in Australia, Canada, and Japan; and a global emission reduction credit scheme – the Clean Development Mechanism (CDM) – has an enthusiastic and important constituency of supporters in the form of the world’s developing countries.

So, despite the fact that there has been an undeniable loss of momentum due to recent political developments in Australia, Japan, and the United States, it remains true that cap-and-trade is still the most likely domestic policy approach for CO2 emissions reductions throughout the industrialized world, given the rather unattractive set of available alternative approaches.  This makes it important to think about the possibility of linking these national and regional cap-and-trade systems in the future.  Such linking occurs when the government that maintains one system allows regulated entities to use allowances or credits from other systems to meet compliance obligations.

Thinking About Linkage

In 2007, with support from the International Emissions Trading Association (IETA) and the Electric Power Research Institute (EPRI), Judson Jaffe and I analyzed the opportunities and challenges presented by linking tradable permit systems.  Jaffe was then at Analysis Group in Boston, and is now at the U.S. Department of the Treasury.  We presented our findings at the thirteenth Conference of the Parties of the U.N. Framework Convention on Climate Change in Bali, Indonesia, in December, 2007.  In 2010, Matthew Ranson (a Ph.D. student in Public Policy at Harvard), Jaffe, and I expanded on these ideas in an article that was published in Ecology Law Quarterly, “Linking Tradable Permit Systems:  A Key Element of Emerging International Climate Policy.” In today’s blog post, I summarize the highlights of this complex, yet important topic.

First, for anyone new to this territory, let me review the basic facts.  Tradable permit systems fall into two categories:  cap-and-trade and emission reduction credits.  Under cap-and-trade (CAT), the total emissions of regulated sources are capped and the sources are required to hold allowances equal to their emissions.  Under a credit system, entities that voluntarily undertake emission reduction projects are awarded credits that can be sold to participants in cap-and-trade systems.

The Merits of Linking

By broadening markets for allowances and credits, linking increases the liquidity and improves the functioning of markets.  Linking can reduce the costs of the linked systems by making it possible to shift emission reductions across systems.  Just as allowance trading within a system allows higher-cost emission reductions to be replaced by lower-cost reductions, trading across systems allows higher-cost reductions in one system to be replaced by lower-cost reductions in another system.

Other Implications

Along with the cost savings it can offer, linking has other implications that warrant serious consideration.  Under some circumstances, linked systems collectively will not achieve the same level of emission reductions as they would absent linking.  This can result either from a link’s impact on emissions under the linked systems, or from its impact on emissions leakage from those systems.  Linking also has distributional impacts across and within systems.  And linking can reduce the control that a country has over the impacts of its tradable permit system.  In particular, when a domestic CAT system is linked with another CAT system, decisions by the government overseeing the other system can influence the domestic system’s allowance price, distributional impacts, and emissions.

By the way, linkage can also occur among a heterogeneous set of domestic policy instruments, including carbon taxes and various types of regulation, although the linking is more challenging under such circumstances.  On this, see “Linking Policies When Tastes Differ: Global Climate Policy in a Heterogeneous World,” a discussion paper by Gilbert Metcalf, Department of Economics, Tufts University,  and David Weisbach, University of Chicago Law School, for the Harvard Project on Climate Agreements.

Concerns About Linking

Importantly, trading brought about by unrestricted links between CAT systems will lead to the automatic propagation of certain design elements, including:  offset provisions and linkages with other systems; banking and borrowing of allowances across time; and safety-valve provisions.  If these provisions, sometimes characterized as cost-containment measures, are present in one of the linked systems, they will automatically be made available to participants in the other system.

In the near-term, some links will be more attractive and easier to establish than others.  Given the design-element propagation implications of two-way links between cap-and-trade systems, to facilitate such links it may be necessary to harmonize some design elements.  And in some cases, it may be necessary to establish broader international agreements governing aspects of the design of linked cap-and-trade systems beyond mutual recognition of allowances.

An Emerging De Facto International Climate Policy Architecture?

Whereas some two-way links between cap-and-trade systems may thus take more time to establish, in the near-term one-way links between cap-and-trade and credit systems likely will be more attractive and easier to establish.  A one-way link with a credit system may offer a cap-and-trade system greater cost savings than a two-way link with another cap-and-trade system.  Also, such one-way links can only reduce allowance prices in the cap-and-trade system, giving a government greater control over its system than if it established a two-way link with another cap-and-trade system.  The additionality problem is an important concern associated with such links, but it can be managed – to some degree – through the criteria established for awarding or recognizing credits.

Most important, if emerging cap-and-trade systems link with a common credit system, such as the CDM, this will create indirect links among the cap-and-trade systems.  Through the indirect links that they create, such one-way linkages can achieve much of the near-term cost savings and risk diversification that direct two-way links among cap-and-trade systems would achieve.  And they can do this without requiring the same foundation that likely would be needed to establish direct two-way links, such as harmonization of cost-containment measures.  Such linkage may well emerge as part of the de facto post-Kyoto international climate policy architecture, and is fully consistent with the bottom-up, decentralized approach of the Cancun Agreements.

What Happened (and Why): An Assessment of the Cancun Agreements

The international climate negotiations in Cancun, Mexico, have concluded, and despite the gloom-and-doom predictions that dominated the weeks and months leading up to Cancun, the Sixteenth Conference of the Parties (COP-16) of the United Nations Framework Convention on Climate Change (UNFCCC) must be judged a success.  It represents a set of modest steps forward.  Nothing more should be expected from this process.

As I said in my November 19th essay – Defining Success for Climate Negotiations in Cancun – the key challenge was to continue the process of constructing a sound foundation for meaningful, long-term global action (not necessarily some notion of immediate, highly-visible triumph).  This was accomplished in Cancun.

The Cancun Agreements – as the two key documents (“Outcome of the AWG-LCA” and “Outcome of the AWG-KP”) are called – do just what was needed, namely build on the structure of the Copenhagen Accord with a balanced package that takes meaningful steps toward implementing the key elements of the Accord.  The delegates in Cancun succeeded in writing and adopting an agreement that assembles pledges of greenhouse gas (GHG) cuts by all of the world’s major economies, launches a fund to help the most vulnerable countries, and avoids some political landmines that could have blown up the talks, namely decisions on the (highly uncertain) future of the Kyoto Protocol.

I begin by assessing the key elements of the Cancun Agreements.  Then I examine whether the incremental steps forward represented by the Agreements should really be characterized as a success.  And finally I ask why the negotiations in Cancun led to the outcome they did.

Assessing the Key Elements of the Cancun Agreements

First, the Cancun Agreements provide emission mitigation targets and actions (submitted under the Copenhagen Accord) for approximately 80 countries – including, importantly, all of the major economies. In this way, the Agreements codify pledges by the world’s largest emitters – including China, the United States, the European Union, India, and Brazil – to various targets and actions to reduce emissions by 2020.  The distinction between Annex I and non-Annex I countries is blurred even more in the Cancun Agreements than it was in the Copenhagen Accord – another step in the right direction!

Also, for the first time, countries agreed – under an official UN agreement – to keep temperature increases below a global average of 2 degrees Celsius.  It brings these aspirations, as well as the emission pledges of individual countries, into the formal UN process for the first time, essentially by adopting the Copenhagen Accord one year after it was “noted” at COP-15.  (There’s also an abundance of politically-correct and in some cases downright silly window dressing in the Cancun Agreements, including repetitive references to various interpretations of the UNFCCC’s principle of “common but differentiated responsibilities,” as well as some discussion of examining a 1.5 C target.)

However, despite even the 2 degree (450 ppm concentration) aspirational target, the Agreements are no more stringent that the collection of submissions made under last year’s Copenhagen Accord.  But, as Michael Levi (Council on Foreign Relations) has pointed out, the Cancun Agreement “should be applauded not because it solves everything, but because it chooses not to.” As my colleagues and I have repeatedly emphasized in our work within the Harvard Project on Climate Agreements, many of the most important initiatives for addressing climate change will occur outside of the United Nations process (despite the centrality of that process).

Second, the Agreements elaborate on the mechanisms for monitoring and verification that were laid out in last year’s Accord.  Importantly, these now include “international consultation and analysis” of developing country mitigation actions.  Countries will report their GHG inventories to an independent panel of experts, which will monitor and verify reports of emissions cuts and actions.

Third, the Agreements establish a so-called Green Climate Fund to deliver financing for mitigation and adaptation. Importantly, the Agreements name the World Bank as the interim trustee of the Fund, despite objections from many developing countries, and create an oversight board, half of which consists of donor nation representatives.  In addition, the Agreements establish a goal by developed countries to mobilize $100 billion annually by 2020 to support mitigation and adaptation in developing countries, a funding target which would include public and private resources (that is, carbon markets and private finance), bilateral and multilateral flows, as well as the Green Climate Fund.

Whether the resources ever grow to the size laid out in Copenhagen and Cancun will depend upon the individual actions of the wealthy nations of the world.  However, it’s interesting that the section in the Cancun Agreements on adaptation comes before the section on mitigation.  Things have come a long way since the days when economists were virtually alone in calling for attention to adaptation (along with mitigation).  I recall when economists were therefore accused of throwing in the towel, and not caring about the environment!

Fourth, the Agreements advance initiatives on tropical forest protection (or, in UN parlance, Reduced Deforestation and Forest Degradation, or REDD+), by taking the next steps toward establishing a program in which the wealthy countries can help prevent deforestation in poor countries, possibly working through market mechanisms (despite exhortations from Bolivia and other leftist and left-leaning countries to keep the reach of “global capitalism” out of the policy mix).

Fifth, the Cancun Agreements establish a structure to assess the needs and policies for the transfer to developing countries of technologies for clean energy and adaptation to climate change, and a – as yet undefined – Climate Technology Center and Network to construct a global network to match technology suppliers with technology needs.

In addition, the Agreements endorse an ongoing role for the Clean Development Mechanism (CDM) and other “market-based mechanisms;” indicate that carbon capture and storage (CCS) projects should be eligible for carbon credits in the CDM; and offer some special recognition of the situations of the Central and Eastern European countries (previously known in UN parlance as “parties undergoing transition to a market economy”) and Turkey, all of which are Annex I countries under the Kyoto Protocol, but decidedly poorer than the other members of that group of industrialized nations.

That’s the 32-page Cancun Agreements in a nutshell.  As a member of one of the leading national delegations said to me in Cancun a few hours after the talks had concluded, “It’s incremental progress, but progress nonetheless.”

Are Such Incremental Steps Really a Success?

Recall from my November 19th essay that the best goal for the Cancun climate talks was to make real progress on a sound foundation for meaningful, long-term global action.  I said that because of some fundamental scientific and economic realities, which I will not repeat here.  In that previous essay, I also described “What Would Constitute Real Progress in Cancun” A quick comparison of my criteria from November 19th and the Cancun Agreements of December 11th tells me that the outcome of Cancun should be judged a success.

My first criterion of success was that the UNFCCC should embrace the parallel processes that are carrying out multilateral discussions on climate change policy:  the Major Economies Forum or MEF (a multilateral venue for discussions – but not negotiations – among the most important emitting countries); the G20 (periodic meetings of the finance ministers – and sometimes heads of government – of the twenty largest economies in the world); and various other multilateral and bilateral organizations and discussions.  Although the previous leadership of the UNFCCC seemed to view the MEF, the G20, and most other non-UNFCCC forums as competition – indeed, as a threat, the UNFCCC’s new leadership under Executive Secretary Christiana Figueres displays a positive and pragmatic attitude toward these parallel processes.

My second criterion was that the three major negotiating tracks be consolidated.  These tracks were:  first, the UNFCCC’s KP track (negotiating national targets for a possible second commitment period – post-2012 – for the Kyoto Protocol); second, the LCA track (the UNFCCC’s negotiation track for Long-term Cooperative Action, that is, a future international agreement of undefined nature); and third, the Copenhagen Accord, negotiated and noted at COP-15 in Copenhagen, Denmark, in December, 2009.

Permit me, please, to quote from my November 19th essay:

Consolidating these three tracks into two tracks (or better yet, one track) would be another significant step forward.  One way this could happen would be for the LCA negotiations to take as their point of departure the existing Copenhagen Accord, which itself marked an important step forward by blurring for the first time (although not eliminating) the unproductive and utterly obsolete distinction in the Kyoto Protocol between Annex I and non-Annex I countries.  (Note that more than 50 non-Annex I countries now have greater per capita income than the poorest of the Annex I countries.)

This is precisely what has happened.  The Cancun Agreements – the product of the LCA-track negotiations – build directly, explicitly, and comprehensively on the Copenhagen Accord.  The two tracks have become one.

Alas, the KP track remains, and a decision on a potential second commitment period (post-2012) for the Kyoto Protocol has been punted to COP-17 in Durban, South Africa, in December, 2011.  It is difficult to picture a meaningful – or any – second commitment period for the Kyoto Protocol, with the United States out of that picture, and with Japan and Russia having stated unequivocally that they will not take up another set of targets, and with Australia and Canada also unlikely to participate.  But note that this issue will have to be confronted in Durban a year from now.  With the first commitment period of the Kyoto Protocol ending in 2012, COP-17 will provide the last opportunity for punting that contentious issue.

If you agree with my view – which I have written about in many previous blog posts – that the Kyoto Protocol is fundamentally flawed and that the Protocol’s dichotomous distinction between Annex I and non-Annex I countries is the heavy anchor that slows meaningful progress on international climate policy, then you will not consider it bad news that a second commitment period for the Protocol is looking less and less likely.  On the other hand, you will, in that case, share my disappointment that the issue has been punted (recognizing, however, that had it not been punted, the Cancun meetings could have collapsed amidst acrimony and recriminations).

I also wrote in my November 19th post:

The UNFCCC principle of “common but differentiated responsibilities” could be made meaningful through the dual principles that:  all countries recognize their historic emissions (read, the industrialized world); and all countries are responsible for their future emissions (think of those rapidly-growing emerging economies).

The Cancun Agreements do this by recognizing directly and explicitly these dual principles.  This can represent the next step in a movement beyond what has become the “QWERTY keyboard” (that is, unproductive path dependence) of international climate policy:  the distinction in the Kyoto Protocol between the small set of Annex I countries with quantitative targets, and the majority of countries in the world with no responsibilities.

A variety of policy architectures can build on these dual principles and make them operational, bridging the political divide which exists between the industrialized and the developing world.  (At the Harvard Project on Climate Agreements, we have developed a variety of architectural proposals that could make these dual principles operational.  See, for example:  “Global Climate Policy Architecture and Political Feasibility: Specific Formulas and Emission Targets to Attain 460 PPM CO2 Concentrations” by Valentina Bosetti and Jeffrey Frankel; and “Three Key Elements of Post-2012 International Climate Policy Architecture” by Sheila M. Olmstead and Robert N. Stavins.)

My third criterion for success was movement forward with specific, narrow agreements, such as on:  REDD+ (Reduced Deforestation and Forest Degradation, plus enhancement of forest carbon stocks); finance; and technology.  Such movement forward has, in fact, occurred in all three domains in the Cancun Agreements, as I described above.

My fourth criterion for success was keyed to whether the parties to the Cancun meetings could maintain sensible expectations and thereby develop effective plans.  This they have done.  The key question was not what Cancun accomplishes in the short-term, but whether it helps put the world in a better position five, ten, and twenty years from now in regard to an effective long-term path of action to address the threat of global climate change.

Despite the fact that some advocacy groups – and for that matter, some nations – are no doubt disappointed with the outcome of Cancun, I think it is fair to say that this final criterion for success was satisfied:  the Cancun Agreements can help put the world on a path toward an effective long-term plan of meaningful action.

Why Did Cancun Succeed?

If you agree with my assessment of success in Cancun, then a reasonable question to ask is why did the Cancun talks produce this successful outcome, particularly in contrast with what many people consider a less successful outcome of the Copenhagen talks last year.  To address this question, let me expand on some points made in an insightful essay by Elliot Diringer, Vice President for International Strategies at the Pew Center on Global Climate Change.

First, the Mexican government through careful and methodical planning over the past year prepared itself well, and displayed tremendous skill in presiding over the talks. Reflect, if you will, on the brilliant way in which Mexican Minister of Foreign Affairs, Patricia Espinosa, who served as President of COP-16, took note of the objections of Bolivia (and, at times, several other leftist and left-leaning Latin American countries, known collectively as the ALBA states), and then simply ruled that the support of 193 other countries meant that “consensus” had been achieved and the Cancun Agreements had been adopted by the Conference.  At a critical moment, Ms. Espinosa noted that “consensus does not mean unanimity,” and that was that!

Compare this with the unfortunate chairing of COP-15 in Copenhagen by Danish Prime Minister Lars Løkke Rasmussen, who allowed the objections by a similar same small set of five relatively unimportant countries (Bolivia, Cuba, Nicaragua, Sudan, and Venezuela) to derail those talks, which hence “noted,” but did not adopt the Copenhagen Accord in December, 2009.

The Mexicans were also adept at facilitating small groups of countries to meet to advance productive negotiations, but made sure that any countries could join those meetings if they wanted.  Hence, negotiations moved forward, but without the sense of exclusivity that alienated so many small (and some large) countries in Copenhagen.

The key role played by the Mexican leadership is consistent with the notion of Mexico as one of a small number of “bridging states,” which can play particularly important roles in this process because of their credibility in the two worlds that engage in divisive debates in the United Nations:  the developed world and the developing world.  We have examined this in our recent Harvard Project on Climate Agreements Issue Brief, Institutions for International Climate GovernanceMexico, along with Korea, are members of the OECD, but are also non-Annex I countries under the Kyoto Protocol.  This gives Mexico — and gave Minister Espinosa — a degree of credibility across the diverse constituencies in the UNFCCC that was simply not enjoyed by Danish Prime Minister Rasmussen at COP-15 last year.

Second, China and the United States set the tone for many other countries by dealing with each other with civility, if not always with understanding.  This contrasts with the tone that dominated in and after Copenhagen, when finger-pointing at Copenhagen between these two giants of the international stage led to a blame-game in the months after the Copenhagen talks.

As Elliot Diringer wrote, they may have recognized that “the best way to avoid blame was to avoid failure.”  Beyond this, although the credit must go to both countries, the change from last year in the conduct of the Chinese delegation was striking.  It appeared, as Coral Davenport wrote in The National Journal, that the Chinese were on a “charm offensive.”  Working in Cancun on behalf of the Harvard Project on Climate Agreements, I can personally vouch for the tremendous increase from previous years in the openness of members of the official Chinese delegation, as well as the many Chinese members of civil society who attended the Cancun meetings.

Third, a worry hovered over the Cancun meetings that an outcome perceived to be failure would lead to the demise of the UN process itself.  Since many nations (in particular, developing countries, which made up the vast majority of the 194 countries present in Cancun) very much want the United Nations and the UNFCCC to remain the core of international negotiations on climate change, that implicit threat provided a strong incentive for many countries to make sure that the Cancun talks did not “fail.”

Fourth, under the pragmatic leadership of UNFCCC Executive Secretary Christiana Figueres, realism may have finally eclipsed idealism in these international negotiations. Many observers have noted that many delegations – and probably most civil society NGO participants – at the previous COPs have misled themselves into thinking that ambitious cuts in greenhouse gases (GHGs) were forthcoming that could guarantee achievement of the 450 ppm/2 degrees C cap.

The acceptance of the Cancun Agreements suggests that the international diplomatic community may now recognize that incremental steps in the right direction are better than acrimonious debates over unachievable targets.  This harkens back to what I characterized prior to COP-16 as the key challenge facing the negotiators:  to continue the process of constructing a sound foundation for meaningful, long-term global action.  In my view, this was accomplished in Cancun.
