Paris Can Be a Key Step

I returned from a brief trip to Paris two days before the horrific events of November 13^th, which have shocked and saddened civilized people everywhere. I was in Paris for discussions regarding climate change policy at OECD headquarters. Now, I’m preparing to return to Paris in less than two weeks with my colleagues from the Harvard Project on Climate Agreements (I’ve inserted a list of our forthcoming “public” activities at the Paris climate talks at the end of this blog post).

My purpose today, in this essay, is to explain why I believe that the Paris talks may turn out to be a key step in the international negotiations, and more important, a significant step in efforts to address the threat of climate change.

Background on the Paris Climate Talks

The international climate change negotiations that will take place in Paris the first two weeks of December, 2015, are officially the 21^st Conference of the Parties of the United Nations Framework Convention on Climate Change. It will be many years before any of us can truly assess the impact of the Paris talks, but it is clear now that they represent – at the very least – an important attempt to break with the past thrust of international climate policy and start anew with a much more promising approach.

The Kyoto Protocol, which has been the primary international agreement to reduce the greenhouse-gas emissions that cause global climate change, included mandatory emissions-reduction obligations only for developed countries. Developing countries had no emissions-reduction commitments. The stark demarcation in the Kyoto Protocol between developed and developing countries was one approach to realizing a principle in the underlying United Nations Framework Convention on Climate Change (UNFCCC), that countries should act to “protect the climate system … on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities.”

The dichotomous distinction between the developed and developing countries in the Kyoto Protocol has made progress on climate change impossible, because growth in emissions since the Protocol came into force in 2005 is entirely in the large developing countries—China, India, Brazil, Korea, South Africa, Mexico, and Indonesia. The big break came at the annual UNFCCC negotiating session in Durban, South Africa in 2011, where a decision was adopted by member countries to “develop [by December 2015, in Paris] a protocol, another legal instrument or an agreed outcome with legal force under the Convention applicable to all Parties.” This “Durban Platform for Enhanced Action” broke with the Kyoto Protocol and signaled a new opening for innovative thinking (which we, at the Harvard Project on Climate Agreements, took to heart).

The Road to Paris

In Paris next month, countries will likely adopt a new hybrid international climate policy architecture that includes: bottom-up elements in the form of “Intended Nationally Determined Contributions” (INDCs), which are national targets and actions that arise from national policies; and top-down elements for oversight, guidance, and coordination. Now, all countries will be involved.

The current commitment period of the Kyoto Protocol covers countries (Europe and New Zealand) accounting for no more than 14% of global emissions (and 0% of global emissions growth). But as of November 9^th, 156 of the 196 members of the UNFCCC had submitted INDCs, representing some 87% of global emissions (and this will likely reach 90% or 95% by the time of the Paris talks)!

Such broad scope of participation is a necessary condition for meaningful action, but it is not a sufficient condition. Also required is adequate ambition of the individual contributions. But keep in mind that this is only the first step with this new approach. The INDCs will likely be assessed and revised every five years, with their collective ambition ratcheted up over time. That said, even this initial set of contributions could cut anticipated temperature increases this century to about 2.7-3.5 degrees Centigrade, more than the frequently-discussed aspirational goal of limiting temperature increases to 2 degrees C, but much less than the 5-6 degrees C increase that would be expected without this action. (An amendment to the Montreal Protocol to address hydrofluorocarbons (HFCs) will quite possibly shave an addition 0.5 C of warming.)

The problem has not been solved, and it will not be for years to come, but the new approach being taken in the forthcoming Paris Agreement can be a key step toward reducing the threat of global climate change. Only time will tell.

A Paris Scorecard

I’ve been asked many times what success will look like in Paris. Here’s my scorecard and my predictions of five key elements that – if all were achieved — would constitute an exceptionally successful 21^st Conference of the Parties:

Include approximately 90% of global emissions in the set of INDCs that are submitted and part of the Paris Agreement (compared with 14% in the current commitment period of the Kyoto Protocol). This will definitely be achieved.

Establish credible reporting and transparency requirements. It is likely that this will be achieved.

Begin to set up a system to finance climate adaptation (and mitigation) — the famous $100 billion commitment. A key question is whether it includes private-sector finance, in addition to public-sector finance (that is, foreign aid). This is likely to be achieved.

Agree to return to negotiations periodically, such as every 5 years, to revisit the ambition and structure of the INDCs. It is likely this will be achieved.

Put aside unproductive disagreements, such as on so-called “loss and damage,” which looks to rich countries like unlimited liability for bad weather events in developing countries. Another unproductive disagreement is the insistence by some parties that the INDCs themselves be binding under international law. This would probably mean that the Paris Agreement would require Senate ratification in the United States, which means that the United States would not be a party to the Agreement. I can only hope that the delegates will realize the futility of pursuing such unproductive elements.

As you can see, I anticipate that elements #1 through #4 will be achieved in the Paris Agreement, and hopefully #5 as well. So, my fundamental prediction for Paris is success. (Unfortunately, some greens and some members of the press will mistakenly characterize this same outcome as “failure,” because the 2 degree C target has not been achieved immediately.)

Finally, for those of you who will be in Paris and/or like to keep up on the work of the Harvard Project on Climate Agreements, here is a partial schedule of our activities there (“partial” only because some of our engagements, including numerous bilateral meetings with national negotiating teams, press engagements, and other private meetings, are not included):

The Papal Encyclical and Climate Change Policy

On June 18, 2015, Coral Davenport, writing in the New York Times, was the first in the press to note that the encyclical on the environment, Laudato Si’, released by Pope Francis that same day, with tremendous praise from diverse quarters, “is as much an indictment of the global economic order as it is an argument for the world to confront climate change.”

The New York Times and a Couple of Asia Trips

The Times article included the following: “…environmental economists criticized the encyclical’s condemnation of carbon trading, seeing it as part of a radical critique of market economies. ‘I respect what the pope says about the need for action, but this is out of step with the thinking and the work of informed policy analysts around the world, who recognize that we can do more, faster, and better with the use of market-based policy instruments — carbon taxes and/or cap-and-trade systems,’ Robert N. Stavins, the director of the environmental economics program at Harvard, said in an email. The approach by the pope, an Argentine who is the first pontiff from the developing world, is similar to that of a ‘small set of socialist Latin American countries that are opposed to the world economic order, fearful of free markets, and have been utterly dismissive and uncooperative in the international climate negotiations, Dr. Stavins said.”

Those are accurate quotes from an email I sent to Coral Davenport in response to her inquiry the same day. The reason why I sent an email, rather than calling was that I was, at that moment, approximately 37,000 feet over the Pacific Ocean, flying from Seoul (where I had spoken at the third annual Future Energy Forum) to San Francisco, on my way home to Boston.

The following week, I was flying back to Asia (this time to Beijing for a workshop jointly sponsored by the Harvard Project on Climate Agreements and China’s National Development and Reform Commission – a topic for a future blog post, but not for today). As I sat in the departure lounge at Chicago’s O’Hare International, I began to see on my iPhone a small flood of hostile commentary from the blogosphere, indicating that I had unfairly “attacked the Pope.”

Well, writing an email rather than chatting on the phone with a reporter may eliminate some spontaneity, but it does have the advantage of preserving a record. So, I’m pleased to be able to share with readers today the views I offered on June 18^th, long before the Pope’s recent visit to Cuba and the United States. My views have not changed.

Why Write About This Now?

That’s a reasonable question. In part, I’m inspired by a marvelous essay by Yale professor William Nordhaus, “The Pope & the Market,” which appears in the October 8, 2015 issue of The New York Review of Books. However, my thoughts are completely independent from his, and so he should not be indicted for anything I have to say. But I do heartily recommend his essay, and urge readers to take a look at his commentary (as well as mine).

With that preamble out of the way, here are the reactions of one environmental economist, yours truly, to Laudato Si’, nearly verbatim from my June 18^th message from 37,000 feet over the Pacific Ocean, with some additional text and links for this blog essay.

An Environmental Economist Reflects on the Papal Encyclical

The Pope is to be commended for taking global climate change seriously, and for drawing more world attention to the issue. There is much about the encyclical that is commendable, but where it drifts into matters of public policy, I fear that it is – unfortunately – not helpful.

The long encyclical ignores the causes of global climate change: it is an externality, an unintended negative consequence of otherwise meritorious activity by producers producing the goods and services people want, and consumers using those goods and services. That’s why the problem exists in the first place. There may well be ethical dimensions of the problem, but it is much more than a simple consequence of some immoral actions by corrupt capitalists.

The document also ignores the global commons nature of the problem, which is why international cooperation is necessary. If the causes of the problem are not recognized, it is very difficult – or impossible – to come up with truly meaningful and feasible policy solutions.

So, yes, the problem is indeed caused by a failure of markets, as the Pope might say, or – in the language of economics – a “market failure”. But that is precisely why sound economic analysis of the problem is important and can be very helpful. Such analysis points the way to working through the market for solutions, rather than condemning global capitalism per se.

Should Carbon Markets be Condemned?

In surprisingly specific and unambiguous language, the encyclical rejects outright “carbon credits” as part of a solution to the problem. It says they “could give rise to a new form of speculation and would not help to reduce the overall emission of polluting gases”. The encyclical asserts that such an approach would help “support the super-consumption of certain countries and sectors”.

That misleading and fundamentally misguided rhetoric is straight out of the playbook of the ALBA countries, the small set of socialist Latin American countries that are opposed to the world economic order, fearful of free markets, and have been utterly dismissive and uncooperative in the international climate negotiations. Those countries have been strongly opposed to any market-based approaches to climate change, including carbon taxes, cap-and-trade, and offset systems, as well as any approaches that would allow – through appropriate linkage – the financing by one country of emissions reductions in another country (see my previous essay at this blog on A Key Element for the Forthcoming Paris Climate Agreement).

If the references to “carbon credits” were intended to refer only to offset systems (such as the Clean Development Mechanism) and not to cap-and-trade systems, then I would be much less concerned about the Pope’s complaints. However, the encyclical does not make the distinction. Indeed, I doubt that the authors of the encyclical recognize the difference, and unfortunately, readers of the encyclical will likewise lump together all carbon markets, which is what some policy makers also do, unfortunately.

Out of Step

I respect what the Pope says about the need for action, but his unfortunate attack on the use of the market to address climate change is out of step with the thinking and the work of informed policy analysts and policy makers around the world, who recognize that we can do more, faster, and better with the use of market-based policy instruments – carbon taxes and/or cap-and-trade systems. UN Secretary General Ban Ki-moon has been outspoken in precisely this regard.

Furthermore, the United Nations Framework Convention on Climate Change itself (Article 3.3) explicitly states that “policies and measures to deal with climate change should be cost-effective so as to ensure global benefits at the lowest possible cost” and thereby be more ambitious. That is why market-based climate policy instruments are an important option for many countries. Keeping costs down will help inspire greater action.

Concluding Thoughts

The Papacy is to be commended for having drawn attention to climate change as a major issue. But, sadly, the encyclical fails to recognize that because externalities (such as CO₂ emissions) are a type of market failure and because the global commons nature of the problem and consequent free riding are also a profound market failure, it is for these reasons that working through the market is absolutely necessary – in order to address the climate problem in ways that are scientifically meaningful, economically sensible, and ultimately politically pragmatic.

By incorporating the anti-market rhetoric of the ALBA countries, the encyclical unfortunately goes beyond these errors of omission to incorporate significant errors of commission by emphasizing a perspective that is not progressive and enlightened, and would – I fear – ultimately work against meaningful climate policy at the international, regional, national, and sub-national levels.

That is why I said that although there is much about the encyclical that is commendable, where it drifts into matters of public policy it is – unfortunately – not helpful.

A Key Element for the Forthcoming Paris Climate Agreement

The upcoming Paris climate negotiations will constitute a critical step in the ongoing international process to reduce global greenhouse gas (GHG) emissions. The question of whether the Paris outcome will be sufficiently ambitious to put the world on a path towards limiting global average warming to 2^o C, as agreed in Cancun, can be answered now. It will not, because that target, while possibly useful as an aspirational goal, is not achievable, as the most recent report of Working Group III of the IPCC documented. What is clear, however, is that greater ambition is more easily realized when costs are low. Market-based mechanisms are an important element in the portfolio of actions that can lead to cost-effective solutions. Linkage – between and among market and non-market systems for reducing GHG emissions – is a closely-related key element.

In an article just published in Climate Policy, “Facilitating Linkage of Climate Policies through the Paris Outcome,” my co-authors – Daniel Bodansky of Arizona State University, Seth Hoedl of Harvard Law School, and Gilbert Metcalf of Tufts University – and I examine how the Paris outcome, and more generally the ongoing climate negotiations, can allow for and advance linked systems.

Brief Background

In the Durban Platform for Enhanced Action, adopted by the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) in 2011, the parties agreed to develop a “protocol, another legal instrument or an agreed outcome with legal force under the Convention applicable to all Parties,” for adoption at COP-21 in December, 2015, in Paris. It is likely that the Paris outcome will reflect a hybrid climate policy architecture – one that combines top-down elements, such as for monitoring, reporting, and verification (MRV), with bottom-up elements, including “Intended Nationally Determined Contributions” (INDCs), describing what a country intends to do to reduce emissions, based on domestic political feasibility and other factors. This outcome will be embodied in a core agreement, which likely will be legally binding, as well as ancillary instruments such as annexes, national schedules, and COP decisions.

The ability to link regional, national, and sub-national climate policies will be essential to enhancing the cost-effectiveness of such a system – and thus the likelihood of achieving significant global emissions reductions. By ‘linkage’, we mean formal recognition by a GHG mitigation program in one jurisdiction (a regional, national, or sub-national government) of emission reductions undertaken in another jurisdiction for the purposes of complying with the first jurisdiction’s requirements.

First Necessity for Paris: Do No Harm

The minimum requirement for the Paris agreement in regard to linkage is to do no harm. Silence on linkage could possibly accomplish that. But any provisions in the agreement that would require nations to achieve their respective INDCs exclusively within their own borders – a constraint that has been favored by the ALBA countries – would, in effect, prohibit not only international carbon markets but any sort of meaningful linkage (and would thereby greatly drive up costs).

Common Definitions of Key Terms

If linkage is to play a significant role in a hybrid international policy architecture, then several categories of design elements merit serious consideration for inclusion in the Paris outcome, either directly or by establishing a process for subsequent international negotiations. In general, effective linkage requires common definitions of key terms, including particularly the units to be used for compliance purposes. This will be particularly important for links between heterogeneous systems, and it is an area where a model rule could be particularly helpful (more about this below).

Registries and Tracking

Linkage requires registries and tracking mechanisms, whether the systems being linked are homogeneous or heterogeneous. Indeed, a key role for the top-down part of a hybrid architecture that allows for international linkage of national policy instruments will be the tracking, reporting, and recording of allowance unit transactions.

International compliance units would make the functioning of an international transaction log more straightforward and reduce the administrative burden of reconciling international registries with national registries. Minimum standards for approving and measuring offsets may be important. Market oversight and monitoring may increase confidence in the system, although in some cases, national and international institutions that can provide oversight already exist and may need only relatively minor additional capacity to assume these functions.

Too Much of a Good Thing Can be Bad

Including detailed linkage rules in the core agreement is not desirable as this could make it difficult for rules to evolve in light of experience. Instead, minimum standards to ensure environmental integrity should be elaborated in COP decisions, or by other means; for example, the COP could establish minimum requirements for national monitoring, reporting, and verification (MRV), registries, and crediting mechanisms.

In terms of linkage, the function of the core agreement might be confined to articulating general principles relating to environmental integrity, while also authorizing the COP or another organization to develop more detailed rules. Whatever minimum standards are adopted, oversight of compliance will be important to ensure the integrity both of the Paris outcome and of linked national systems.

The Utility of Default or Model Rules

Many elements of GHG linkage can be addressed through default or model rules from which nations are free to deviate at their discretion. Rules that may benefit from this approach are typically concerned with the details of linking two regulatory systems. For example, nations interested in linking their cap-and-trade systems would have to consider rules for market coverage, cost containment, banking and borrowing, compliance periods, allocation methods, and the treatment of new emitters and emitter closures. Additional rules may be needed for linking of heterogeneous systems.

Developing uniform rules to address all of these issues is unrealistic. Instead, a degree of harmonization could be achieved through default rules that facilitate linkage by providing a common framework for nations to use when developing their own linkage agreements. Although there is no need for the core agreement itself to elaborate harmonized linkage rules, it might authorize the COP to develop default linkage rules that nations can use in negotiating bilateral linkage agreements.

Less is More

In our Climate Policy article, Dan Bodansky, Seth Hoedl, Gib Metcalf, and I conclude that the most valuable outcome of Paris regarding linkage might simply be the inclusion in the core agreement of an explicit statement that parties may transfer portions of their INDCs to other parties and that these transferred units may be used by the transferees to implement their INDCs. Such a statement would help provide certainty both to governments and private market participants. This minimalist approach will allow diverse forms of linkage to arise, among what will inevitably be highly heterogeneous INDCs, thereby advancing the dual objectives of cost effectiveness and environmental integrity in the international climate policy regime.
