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.

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.

Good News from the Regulatory Front

As each day passes, the upcoming November 2012 general elections produce new stories about potential Republican candidates for President, as well as stories about President Obama’s anticipated re-election campaign. At the same time, the 2012 elections are already affecting Congressional debates, where each side seems increasingly interested in taking symbolic actions and scoring political points that can play to its constituencies among the electorate, rather than working earnestly on the country’s business.

The new Tea Party Republicans in the House of Representatives decry the “fact” that the U.S. Environmental Protection Agency (EPA) continues to promulgate “job-killing regulations” for made-up non-problems. And Democrats in the Congress – not to mention the Administration – are eager to talk about “win-win” policies that will produce “clean energy jobs” and protect Americans from the evils of imported oil and gas.

Neither side seems willing to admit that environmental regulations bring both good news – a cleaner environment – and bad news – costs of compliance that affect not only businesses but consumers as well. Sometimes the cost-side of proposed regulations dominates. Those regulatory moves are – from an economic perspective – fundamentally unwise, since they make society worse off. In other cases, the benefits of a proposed regulation more than justify the costs that will be incurred. Such regulations are – to use a word now favored by President Obama – a wise investment. They make society better off. Failure to take action on such opportunities is imprudent, if not irresponsible. Just such an opportunity now presents itself with EPA’s Clean Air Transport Rule.

In an op-ed that appeared on April 25, 2011, in The Huffington Post (click here for link to the original op-ed), Richard Schmalensee and I assess this opportunity. Rather than summarize (or expand on) our op-ed, I simply re-produce it below as it was published by The Huffington Post, with some hyperlinks added for interested readers.

An Opportunity for Timely Action: EPA’s Transport Rule Passes the Test

by Richard Schmalensee and Robert Stavins

The Huffington Post, April 25, 2011

At a time when EPA regulations are under harsh attack, one new environmental regulation – at least – stands out as an impressive winner for the country. Studies of the soon-to-be-finalized Clean Air Transport Rule have consistently found that the benefits created by the rule would far outweigh its costs. By reducing sulfur dioxide and nitrogen oxide emissions from power plants in 31 states in the East and Midwest, the Transport Rule will create substantial benefits through lower incidence of respiratory and heart disease, improved visibility, enhanced agricultural and forestry yields, improved ecosystem services, and other environmental amenities. According to EPA, these benefits will be 25 to 130 times greater than the associated costs. We document this in our new report, “A Guide to Economic and Policy Analysis of EPA’s Transport Rule,” which was commissioned by the Exelon Corporation.

Despite the benefits offered by the Transport Rule, some argue that it – and other EPA regulations – will stifle economic growth and threaten the reliability of our electric power system. However, a careful look at the evidence reveals that the Transport Rule is unlikely to create such risks. Analyses of the Transport Rule have found that it need not lead to significant plant retirements. Robust regulatory and market mechanisms ensure that the nation can meet emission targets while reliably meeting customer demand.

While compliance with the Transport Rule would – in some cases – require installation of new pollution control equipment, the capital expenditures required would comprise a small fraction of aggregate capital spending by the power industry. In fact, because of the Transport Rule’s unique legal circumstances, in which the Courts have mandated that EPA replace a stringent predecessor, utilities have already begun to make pollution control investments needed to comply with the Transport Rule.

The Rule’s timing can also contribute to lowering its cost and supporting other policy goals. Installation of the pollution control technologies needed to comply with the Rule could increase short-term employment. Although the longer term job impacts are less clear, these short-term employment effects would complement other policy initiatives aimed at supporting the nation’s economic recovery.

EPA analysis estimates modest impacts on regional electricity rates, but reductions in health care expenditures could partially or fully offset these effects. Expanded supplies of low-cost natural gas can also help lower the Transport Rule’s cost by providing a less costly substitute for power generated from coal.

Most importantly, actions taken to reduce emissions would create substantial health benefits. Tens of thousands of premature deaths would be eliminated annually, as would millions of non-fatal respiratory and cardiovascular illnesses. A diverse set of studies find that these health improvements will create $20 to over $300 billion in benefits annually. And, while the Transport Rule is designed to reduce the impact of upwind emissions on downwind states, upwind states would also receive substantial health benefits from the cleaner air brought about by the Rule. These upwind states have much to gain, because states with the highest emissions from coal-fired power plants are also among those with the greatest premature mortality rates from these emissions.

Along with these health benefits, the largest shares of short-term improvements in employment and regional economies are likely to accrue to the regions that are most dependent on coal-fired power, as they invest in new pollution control equipment. Thus, while designed to help regions downwind of coal-fired power plants, the Transport Rule also offers substantial benefits to upwind states.

As the U.S. economy emerges from its worst recession since the Great Depression of the 1930s and faces an increasingly competitive global marketplace, regulation such as the Transport Rule that creates positive net benefits and allows industry flexibility in creating public goods can complement strategies intended to foster economic growth. Such regulations are best identified by careful analyses to ensure that benefits truly exceed costs and avoid unfair impacts on particular groups or sectors. The Transport Rule has undergone a series of such thorough assessments, and the results consistently indicate that it would create benefits that far exceed its costs. Failure to take timely action on this opportunity would seem to be imprudent, if not irresponsible.
