The Platform Opens a Window: An Unambiguous Consequence of the Durban Climate Talks

In my previous essay – following the 17^th Conference of the Parties (COP-17) of the United Nations Framework Convention on Climate Change (UNFCCC), which adjourned on December 11, 2011 – I offered my assessment of the Durban climate negotiations, addressing the frequently-posed question of whether the talks had “succeeded.” I took note of three major outcomes from the negotiations: (1) elaboration on several components of the Cancun Agreements; (2) a second five-year commitment period for the Kyoto Protocol; and (3) a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020. My conclusion was that this package – in total – represented something of a “half-full glass of water,” that is, an outcome that could be judged successful or not, depending upon one’s perspective.

However, something I did not discuss last month is that this third provision – the “Durban Platform for Enhanced Action” – has opened an important window. To explain what I mean requires a brief review of some key points from twenty years of history of international climate negotiations.

The Rio Earth Summit (1992)

The U.N. Framework Convention on Climate Change, adopted at the U.N. Conference on Environment and Development (the first “Earth Summit”) in Rio de Janeiro, Brazil, in 1992, contains what was to become a crucial passage. The first “principle” in Article 3 of the Convention reads as follows: “The Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. Accordingly, the developed country Parties should take the lead in combating climate change and the adverse effects thereof.” [emphasis added] The countries considered to be “developed country Parties” were listed in an appendix to the 1992 Convention – Annex I.

The phrase – common but differentiated responsibilities – has been repeated countless numbers of times since 1992, but what does it really mean? The official answer was provided three years after the Earth Summit by the first decision adopted by the first Conference of the Parties (COP-1) of the U.N. Framework Convention, in Berlin, Germany, April 7, 1995 – the Berlin Mandate.

The Berlin Mandate (1995)

The Berlin Mandate interpreted the principle of “common but differentiated responsibilities” as:

(1) launching a process to commit (by 1997) the Annex I countries to quantified greenhouse gas emissions reductions within specified time periods (targets and timetables); and

(2) stating unambiguously that the process should “not introduce any new commitments for Parties not included in Annex I.”

Thus, the Berlin Mandate established the dichotomous distinction whereby the Annex I countries are to take on emissions-reductions responsibilities, and the non-Annex I countries are to have no such responsibilities whatsoever.

The Kyoto Protocol (1997)

It was in direct response to this Mandate that the U.S. Senate subsequently passed unanimously (95-0) the Byrd-Hagel Resolution in August of 1997 (Senate Resolution 98, 105^th Congress, 1^st Session) stating that:

“It is the sense of the Senate that the United States should not be a signatory to any protocol to, or other agreement regarding, the United Nations Framework Convention on Climate Change of 1992, at negotiations in Kyoto in December 1997, or thereafter, which would mandate new commitments to limit or reduce greenhouse gas emissions for the Annex I Parties, unless the protocol or other agreement also mandates new specific scheduled commitments to limit or reduce greenhouse gas emissions for Developing Country Parties within the same compliance period.”

So, in a very real sense, the Berlin Mandate brought about sustained bi-partisan opposition in the United States to the international climate regime and the Kyoto Protocol. This sealed the Protocol’s fate in terms of ever being ratified by the U.S. Senate. President Clinton did not submit the Protocol to the Senate for ratification, nor would Al Gore have done so had he been elected to succeed Clinton. Likewise, Senator John Kerry was explicit about his opposition to Kyoto when he ran for President against George W. Bush, and President Bush was subsequently more than explicit about his lack of support for the Protocol and, for that matter, the UNFCCC process. When Barack Obama ran against John McCain for President in 2008, one thing on which they agreed was their opposition to the Kyoto Protocol.

Beyond those decisive impacts on U.S. climate politics, the Berlin Mandate had wide-ranging and worldwide normative consequences, because it became the anchor that prevented and has – until very recently – continued to prevent real progress in international climate negotiations. With 50 non-Annex I countries having greater per capita income than the poorest of the Annex I countries, the distinction is clearly out of whack. But, more important than that, this dichotomous distinction means that:

(a) half of global emissions soon will be from nations without constraints;

(b) the world’s largest emitter – China – is unconstrained;

(c) aggregate compliance costs are driven up to be four times their cost-effective level, because many opportunities for low-cost emissions abatement in emerging economies are taken off the table; and

(d) an institutional structure is perpetuated that makes change and progress virtually impossible.

Fast Forward to Copenhagen (2009) and Cancun (2010)

The dichotomous Annex I/non-Annex I distinction remained a central – indeed, the central – feature of international climate negotiations ever since COP-1 in Berlin in 1995. Then, at COP-15 in 2009, there were hints of possible change.

The Copenhagen Accord (2009) and the Cancun Agreements (2010) began a process of blurring the Annex I/non-Annex I distinction. However, this blurring was only in the context of the interim pledge-and-review system established at COP-15 in Copenhagen and certified at COP-16 in Cancun, not in the context of an eventual successor to the Kyoto Protocol. Thus, the Berlin Mandate retained its centrality.

Finally, We Arrive in Durban (2011)

The third of the three outcomes of the December 2011 talks in Durban, South Africa, which I mentioned at the beginning of this essay – the Durban Platform for Enhanced Action – completely eliminates the Annex I/non-Annex I (or industrialized/developing country) distinction. In the Durban Platform, the delegates reached a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020. That’s a strange and confusing sentence, but it’s what happened, and it’s potentially important.

Rather than adopting the Annex I/non-Annex I (or industrialized/developing country) distinction, the Durban Platform focuses instead on the (admittedly non-binding) pledge to create a system of greenhouse gas reductions including all Parties (that is, all key countries) by 2015 that will come into force (after ratification) by 2020. Nowhere in the text of the decision will one find phrases such as “Annex I,” “common but differentiated responsibilities,” “distributional equity,” “historical responsibility,” all of which had long since become code words for targets for the richest countries and blank checks for all others.

A Dramatic Departure

Thus, in a dramatic departure from some seventeen years of U.N. hosted international negotiations on climate change, the 17^th Conference of the Parties in Durban turned away from the Annex I/non-Annex I distinction, which had been the centerpiece of international climate policy and negotiations since it was adopted at the 1^st Conference of the Parties in Berlin in 1995.

Because of this, the international law scholar, Daniel Bodansky, has labeled “the Durban Platform a complete departure from the Berlin Mandate.” Likewise, Indian professor of international law, Lavanya Rajamani says that Durban delivered a “new process and with it, a clean slate on differentiation.” And Elliot Diringer of the Center for Climate and Energy Solutions, finds the overall Durban deal to be “delicately poised between two eras – the fading age of Kyoto, and a new phase … with developed and developing countries presumably on a more equal footing.”

This is of vast potential importance, but – of course – only “potential” importance, because just as it was the Kyoto Protocol’s numerical targets and timetables that fulfilled the Berlin Mandate’s promise, it remains for the delegates to the UNFCCC to meet this Durban mandate with a new post-Kyoto agreement by 2015 (to come into force by 2020). Only time will tell whether the Durban Platform delivers on its promise, or turns out to be another “Bali Roadmap,” leading nowhere.

So, with such uncertainty, what’s the “unambiguous consequence” of Durban that I refer to in the title of this essay?

An Unambiguous Outcome: The Platform Opens a Window

The Durban Platform – by replacing the Berlin Mandate – has opened an important window. It is this. The national delegations from around the world now have a challenging task before them: to identify a new international climate policy architecture that is consistent with the process, pathway, and principles laid out in the Durban Platform, namely to find a way to include all key countries (such as the 20 largest national and regional economies that together account for upwards of 80% of global carbon dioxide emissions) in a structure that brings about meaningful emissions reductions on an appropriate timetable at acceptable cost.

Having broken the old mold, a new one must be forged. There is a mandate for change. Governments around the world now need fresh, outside-of-the-box ideas from the best thinkers, and they need those ideas over the next few years. This is a time for new proposals for future international climate policy architecture, not for incremental adjustments to the old pathway. I trust that this call will be heard by a diverse set of universities, think tanks, and – for that matter – advocacy and interest groups around the world. With 48 research initiatives in Australia, China, Europe, India, Japan, and the United States, the Harvard Project on Climate Agreements is prepared to contribute to this effort. Please stay tuned.

Misguided Objection to Progressive Policy: The EJ Lawsuit Against Implementation of California’s AB 32 Climate Policy

On May 20th, San Francisco Superior Court Judge Ernest Goldsmith ruled that the California Air Resources Board had not adequately explained its choice of a market-based mechanism — a cap-and-trade system — to achieve approximately 20 percent of targeted emissions reductions by 2020 under Assembly Bill 32, the Global Warming Solutions Act of 2006.

The ruling was in response to a lawsuit brought by a set of “environmental justice” groups, who fear that the cap-and-trade system will hurt low-income communities. These groups hope — at a minimum — to delay implementation of the system, scheduled for January 2012. Their preferred outcome would be for California Governor Jerry Brown to abandon the approach altogether in favor of conventional regulatory mechanisms.

I’ve written about this controversy before, but the potential importance of Judge Goldsmith’s ruling suggests that it’s important to revisit this territory.

The National Context

As far as we know, Governor Jerry Brown plans to move forward with the implementation of Assembly Bill 32, the Global Warming Solutions Act, under which California seeks to take dramatic steps to reduce its greenhouse gas emissions. Questions have been raised about the wisdom of a single state trying to address a global commons problem, but with national climate policy developments having slowed dramatically in Washington, California is now the focal point of meaningful U.S. climate policy action. Indeed, for this reason, Nature Magazine recently labeled Mary Nichols, the Chairman of the California Air Resources Board, “America’s top climate cop.”

California’s Plan

A key element of the mechanisms to be used for achieving California’s ambitious emissions reductions will be cap-and-trade, a promising approach with a successful track record, despite its recent demonization as “cap-and-tax” by conservatives and other opponents in the U.S. Congress.

Under this approach, regulators restrict emissions by issuing a limited number of emission allowances, with the number of allowances ratcheted down over time, thus assuring ever-larger reductions in overall emissions. Pollution sources such as electric power plants and factories are allowed to trade allowances, and as a result, sources able to reduce emissions least expensively take on more of the pollution-reduction effort. Experience has shown that cap-and-trade programs achieve emissions reductions at dramatically lower cost than conventional regulation.

Concerns

Some groups in California have been very uneasy about the prospect of cap-and-trade. In particular, the Environmental Justice movement has long opposed this approach, citing concerns that it would hurt low-income communities. Professor Lawrence Goulder of Stanford University and I addressed such concerns in an article in The Sacramento Bee in March of 2008.

One expressed concern has been that a cap-and-trade policy might increase pollution in low-income or minority communities. The apprehension is not about greenhouse gases (the focus of AB 32), since these gases spread evenly around the globe and thus would have no discernible impact in the immediate area. Rather, it’s about “co-pollutants,” such as nitrogen oxides, carbon monoxide, and particulates, which can be emitted alongside greenhouse gases.

Because a cap-and-trade system would reduce California’s overall greenhouse gas emissions, it would also lower the state’s emissions of co-pollutants. Still, it’s possible, though unlikely, that co-pollutant emissions would increase in a particular locality. But here it’s crucial to recognize that existing air pollution laws address such pollutants, and so any greenhouse gas allowance trades that would violate local air pollution limits would be prohibited.

If current limits for co-pollutants are thought to be insufficient, the best response is not to scuttle a statewide system that can achieve AB 32’s ambitious targets at minimum cost. Rather, the most environmentally and economically effective way to address such pollution is to revisit existing local pollution laws and perhaps make them more stringent.

While much attention has been given to the effects of potential climate policies on environmental conditions in low-income communities, it’s also important to consider their economic impacts on these communities. Reducing greenhouse gas emissions will require greater reliance on more costly energy sources and more costly appliances, vehicles and other equipment. Because low-income households devote greater shares of their income to energy and transportation costs than do higher-income households, virtually any climate policy will place relatively greater burdens on low-income households. But because cap-and-trade will minimize energy-related and other costs, it holds an important advantage in this regard over conventional regulations.

Moreover, a cap-and-trade system gives the public a tool for compensating low-income communities for the potential economic burdens: If some emission allowances are auctioned, revenues can be used to mitigate economic burdens on these communities.

The Way Forward

All in all, cap-and-trade serves the goal of environmental justice better than the alternatives. This progressive policy instrument merits a central place in the arsenal of weapons California employs. Beyond helping the state meet its emissions-reduction targets at the lowest cost, it offers a promising way to reduce economic burdens on low-income and minority communities. For these reasons, the EJ lawsuit is not only misguided, but — if ultimately successful — will be counter-productive.

Reflecting on a Century of Progress and Problems

As the first decade of the twenty-first century comes to a close, the problem of the commons is more important to our lives – and more central to economics – than a century ago when the first issue of the American Economic Review appeared, with an examination by Professor Katharine Coman of Wellesley College of “Some Unsettled Problems of Irrigation” (1911). Since that time, 100 years of remarkable economic progress have accompanied 100 years of increasingly challenging problems.

As the U.S. and other economies have grown, the carrying-capacity of the planet – in regard to natural resources and environmental quality – has become a greater concern, particularly for common-property and open-access resources. In an article that appears in the 100^th anniversary issue of the American Economic Review (AER) – “The Problem of the Commons: Still Unsettled After 100 Years” – I focus on some important, unsettled problems of the commons.

100 Years of Economic Progress and More Challenging Environmental Problems

Within the realm of natural resources, there are special challenges associated with renewable resources, which are frequently characterized by open-access. An important example is the degradation of open-access fisheries. Critical commons problems are also associated with environmental quality, including the ultimate commons problem of the twenty-first century – global climate change.

Small communities frequently provide modes of oversight and methods for policing their citizens, a topic about which Professor Elinor Ostrom of Indiana University has written extensively. But as the scale of society has grown, commons problems have spread across communities and even across nations. In some of these cases, no over-arching authority can offer complete control, rendering commons problems more severe.

Although the type of water allocation problems of concern to Coman have frequently been addressed by common-property regimes of collective management, less easily governed problems of open-access are associated with growing concerns about air and water quality, hazardous waste, species extinction, maintenance of stratospheric ozone, and – most recently – the stability of the global climate in the face of the steady accumulation of greenhouse gases.

Whereas common property resources are held as private property by some group, open-access resources are non-excludable. My article in the AER focuses exclusively on the latter, and thereby reflects on some important, unsettled problems of the commons. It identifies both the contributions made by economic analysis and the challenges facing public policy.

The article begins with natural resources, highlighting the difference between most non-renewable natural resources, pure private goods that are both excludable and rival in consumption, and renewable natural resources, many of which are non-excludable.

Some of these are rival in consumption but characterized by open-access. An example is the degradation of ocean fisheries. An economic perspective on these resources helps identify the problems they present for management, and provides guidance for sensible solutions.

The article then turns to a major set of commons problems that were not addressed until the last three decades of the twentieth century – environmental quality. Although frequently characterized as textbook examples of externalities, these problems can also be viewed as a particular category of commons problems: pure public goods, that are both non-excludable and non-rival in consumption.

A key contribution of economics has been the development of market-based approaches to environmental protection, including emission taxes and tradable rights. These have potential to address the ultimate commons problem of the twenty-first century, global climate change.

Themes That Emerge

First, economic theory – by focusing on market failures linked with incomplete systems of property rights – has made major contributions to our understanding of commons problems and the development of prudent public policies.

Second, as our understanding of the commons has become more complex, the design of economic policy instruments has become more sophisticated, enabling policy makers to address problems that are characterized by uncertainty, spatial and temporal heterogeneity, and long duration.

Third, government policies that have not accounted for economic responses have been excessively costly, often ineffective, and sometimes counter-productive.

Fourth, commons problems have not diminished. While some have been addressed successfully, others have emerged that are more important and more difficult.

Fifth, environmental economics is well positioned to offer better understanding and better policies to address these ongoing challenges.

Conclusions

Although I hope you will read the full article – which is very accessible — I will summarize its conclusions here.

Problems of the commons are both more widespread and more important today than when Coman wrote about unsettled problems in the first issue of the American Economic Review 100 years ago. A century of economic growth and globalization have brought unparalleled improvements in societal well-being, but also unprecedented challenges to the carrying-capacity of the planet. What would have been in 1911 inconceivable increases in income and population have come about and have greatly heightened pressures on the commons, particularly where there has been open access to it.

The stocks of a variety of renewable natural resources – including water, forests, fisheries, and numerous other species of plant and animal – have been depleted below socially efficient levels, principally because of poorly-defined property-right regimes. Likewise, the same market failures of open-access – whether characterized as externalities, following A. C. Pigou (1920), or public goods, following Ronald Coase (1960) – have led to the degradation of air and water quality, inappropriate disposal of hazardous waste, depletion of stratospheric ozone, and the atmospheric accumulation of greenhouse gases linked with global climate change.

Over this same century, economics – as a discipline – has gradually come to focus more and more attention on these commons problems, first with regard to natural resources, and more recently with regard to environmental quality. Economic research within academia and think tanks has improved our understanding of the causes and consequences of excessive resource depletion and inefficient environmental degradation, and thereby has helped identify sensible policy solutions.

Conventional regulatory policies, which have not accounted for economic responses, have been excessively costly, ineffective, or even counter-productive. The problems behind what Garrett Hardin (1968) characterized as the “tragedy of the commons” might better be described as the “failure of commons regulation.” As our understanding of the commons has become more complex, the design of economic policy instruments has become more sophisticated.

Problems of the commons have not diminished, and the lag between understanding and action can be long. While some commons problems have been addressed successfully, others continue to emerge. Some – such as the threat of global climate change – are both more important and more difficult than problems of the past.

Fortunately, economics is well positioned to offer better understanding and better policies to address these ongoing challenges. As the first decade of the twenty-first century comes to a close, natural resource and environmental economics has emerged as a productive field of our discipline and one that shows even greater promise for the future.
