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.

Why Cancun Trumped Copenhagen

As we begin the year 2011, a look back at 2010 confirms that the greatest environmental achievement of the past year was the success that was achieved at the Sixteenth Conference of the Parties (COP-16) of the United Nations Framework Convention on Climate Change (UNFCCC) in Cancun, Mexico, in early December. I wrote about this in some detail in my December 13^th essay, “What Happened (and Why): An Assessment of the Cancun Agreements.”

The challenges awaiting delegates later this year (December, 2011) at COP-17 in Durban, South Africa, will be tremendous, particularly in regard to trying to negotiate the massive divide that exists between most Annex I countries and virtually all non-Annex I countries on the fate of a second (post-2012) commitment period for the Kyoto Protocol.

However, on this first day of 2011, it may be helpful to reflect again on the recent success in Cancun, and ask – in particular – why it occurred, because understanding that could provide some valuable lessons for the organizers and hosts of COP-17 in Durban. This was the question I addressed in a brief December 20^th Op-Ed in The Christian Science Monitor, and so rather than attempting to summarize or expand it, I simply reproduce it below.

Why Cancun trumped Copenhagen: Warmer relations on rising temperatures

By Robert N. Stavins
December 20, 2010

Boston —

After the modest results of the climate change talks in Copenhagen a little more than a year ago, expectations were low for the follow-up negotiations in Cancun last month. Gloom-and-doom predictions dominated.

But a funny thing happened on the way to that much-anticipated failure: During two intense weeks of discussions in the Mexican resort that wrapped up at 3 AM on Dec. 12, the world’s governments quietly achieved consensus on a set of substantive steps forward. And equally important, the participants showed encouraging signs of learning to navigate through the unproductive squabbling between developed and developing countries that derailed the Copenhagen talks.

Unprecedented first steps

The tangible advances were noteworthy: The Cancun Agreements set emissions mitigation targets for some 80 countries, including all the major economies. That means that the world’s largest emitters, among them China, the United States, the European Union, India, and Brazil, have now signed up for targets and actions to reduce emissions by 2020.

The participating countries also agreed – for the first time in an official United Nations accord – to keep temperature increases below a global average of 2 degrees Celsius. Yes, that goal is no more stringent than the one set out in Copenhagen, but this time, the participating nations formally accepted the goals; a year earlier, they merely “noted” them, without adopting the accord.

Other provisions establish a “Green Climate Fund” to finance steps to limit and adapt to climate change, and designate the World Bank as interim trustee, over the objections of many developing countries. And new initiatives will protect tropical forests, and find ways to transfer clean energy technology to poorer countries.

The Cancun Agreements on their own are clearly not sufficient to keep temperature increases below 2 degrees Celsius, but they are a valuable step forward in the difficult process of constructing a sound foundation for meaningful, long-term global action.

Small steps vs. global accords

The progress was as much about changing the mindset of how to tackle climate disruption. Significantly, the Cancun agreement blurs the distinction between industrialized and developing countries – a vital step to break through the rich-poor divide that has held up progress for years. The 1997 Kyoto Protocol assigned emission targets only to the 40 countries thought to be part of the industrialized world, which left the more than 140 nations of the developing world without any commitments. But today, more than 50 of those so-called developing countries have higher per capita income than the poorest of the countries with emission-reduction responsibilities under Kyoto.

Implicitly, the process in Cancun also recognizes that smaller, practical steps – some of which are occurring outside the United Nations climate process – are going to be more easily achievable, and thus more effective, than holding out for some overarching thunderclap in a global accord.

The parallel processes of multilateral discussions on climate change policy, including the G20 meetings and the Major Economies Forum, have been useful. For the first time at Cancun, the UN Framework Convention on Climate Change, under the new leadership of Executive Secretary Christiana Figueres, offered a positive and pragmatic approach toward embracing these parallel processes.

Fixing the past (and future)

The Kyoto Protocol, which essentially expires at the end of 2012, is fundamentally flawed, especially in dividing the world into competing economic camps. At Cancun, it was encouraging to hear fewer people holding out for a commitment to another phase of the Kyoto Protocol. It was politically impossible to spike the idea of extending the Kyoto agreement entirely, but at least it was punted to the next gathering in Durban, South Africa, a year from now. Otherwise, the Cancun meeting could have collapsed amid acrimony and recriminations.

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).

This also helps move beyond the old Kyoto divide.

A better dialogue

An essential goal in Cancun was for the parties to maintain sensible expectations and develop effective plans. That they met this challenge owes in good measure to the careful and methodical planning by the Mexican government, and to the tremendous skill of Mexican Foreign Minister Patricia Espinosa in presiding over the talks.

For example, at a critical moment she took note of objections from Bolivia and a few other leftist states, and then ruled that the support of the 193 other countries meant that consensus had been achieved and the Cancun Agreements had been adopted. She pointed out that “consensus does not mean unanimity.” Compare that with Copenhagen, where the Danish prime minister allowed objections by five small countries to derail the talks.

Mexico’s adept leadership also made sure smaller countries were able to contribute fully and join any meetings they wanted, avoiding the sense of exclusivity that alienated some parties in Copenhagen. That’s a sign that Mexico is one of the key “bridging states” that have credibility in both worlds. Another is South Korea. They will need to play key roles going forward.

It’s also vital to note that China and the United States set a civil, productive tone, in contrast to the Copenhagen finger-pointing. From the sidelines in Cancun, I can vouch for the tremendous increase in openness of members of the Chinese delegation.

The acceptance of the Cancun Agreements suggests that the international community may now recognize that incremental steps in the right direction are better than acrimonious debates over unachievable targets.
