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 2o 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.

When Reasonable Policy Discussions Become Unreasonable Personal Attacks

Recently I was reminded of the controversy that erupted late in 2014 about remarks made by the distinguished health economist, Jonathan Gruber, professor at MIT for two decades. Professor Gruber, one of the country’s leading experts on health policy, had played an important role in the construction of the Obama administration’s Patient Protection and Affordable Care Act, subsequently derided by its political opponents as “Obamacare.”

A brief but intense political controversy and media feeding-frenzy erupted when videos surfaced in which Professor Gruber – largely in a series of academic seminars and conferences – explained how the Act was crafted and marketed in ways that would make it easier to develop political support. For example, he noted that insurance companies were taxed instead of patients, fundamentally the same thing economically, but vastly more palatable politically. He went on to note that this was possible because of “the lack of economic understanding of the American voter.” His key point was that the program’s “lack of transparency is a huge political advantage.” Is that a controversial or even unique observation?

A Truism of Political Economy

Any economist who has worked on the development or analysis of public policy – in areas ranging from health care policy to environmental policy to financial regulation – recognizes the truth of the key insight Gruber was communicating to his audiences. It is inevitably in the interests of the advocates of a policy to make the policy’s benefits transparent and to make its costs vague, even unobservable; just as it is in the interests of the opponents of a policy to make that policy’s benefits obscure and its costs as clear as the light of day.

The specific construction of hundreds of public policies are explained by this truism. In the United States, Corporate Average Fuel Economy Standards (or “CAFE standards”) have been a bipartisan Congressional success, despite the fact that the costs they place on the American public per unit of fuel savings are vastly greater than the costs of a commensurate increase in gasoline taxes. Likewise, when conservative opponents of CO2 cap-and-trade wanted to stop the House-passed bill in its tracks, they resorted to demonizing it as “cap-and-tax.”

So, the central lesson Professor Gruber was offering is hardly controversial, and its enunciation ought not lead to the terrible attacks that he suffered. He doesn’t need me to defend him, but he was unfairly demonized, simply because people disagreed with him politically regarding the merits of the public policy he had helped develop and support.

Unfortunately, I was reminded of this recently when I found myself subject to attempted demonization, because someone did not agree with a policy I supported. What happened to me is trivial compared with what Professor Gruber has gone through, but it prompts me to write about it today.

Can We Agree to Disagree?

I have written before at this blog about the reasons why I support my university’s decision not to divest its endowment of its fossil-fuel company holdings. I won’t repeat those arguments here, but will note that I have gone out of my way not to draw conclusions or make recommendations about what other universities or other institutions ought to do in this regard, including when I agreed to write an essay on the subject for Yale Environment 360. My analysis and conclusions were not developed in spite of my decades of research, teaching, and outreach on global climate change policy; rather, they were developed because of my years of work in this area.

There are people, some of whom I greatly respect, who have different perspectives on this issue, and have come to very different conclusions than have I. We have essentially agreed to disagree. They haven’t cast aspersions on me, nor I on them. As my writings on this topic have illustrated, there are many facets to the issue, including economics, politics, ethics, and even religion. No one has cornered the market on wisdom.

And What About the Keystone XL Pipeline?

Likewise, on a quite different topic, on January 8, 2015, Coral Davenport wrote a story in the New York Times about the political debates in Washington regarding the proposed Keystone XL pipeline, and stated that “… most energy and policy experts say the battle over Keystone overshadows the importance of the project as an environmental threat or an engine of the economy. The pipeline will have little effect, they say, on climate change, production of the Canadian oil sands, gasoline prices and the overall job market in the United States.” She went on to quote me (accurately) as having said, “The political fight about Keystone is vastly greater than the economic, environmental or energy impact of the pipeline itself. It doesn’t make a big difference in energy prices, employment or climate change either way.” What I said was consistent with the evidence at the time (note, however, that as oil prices fall, the possibility increases that the Canadian oil sands would be uneconomic to develop without the pipeline). Once again, the analysis is not one-dimensional, and reasonable people can respectfully disagree.

When Policy Debates Become Personal Attacks

But these two topics – the Keystone XL pipeline and fossil-fuel divestment – have increasingly become engulfed in highly-charged campaigns and exceptionally heated political debates. As part of this, my integrity was recently attacked, because of my views.  A young and – I’m sure – well-intentioned climate activist and journalist, writing in the Huffington Post, implied that my assessment in the New York Times of the Washington political debates regarding Keystone XL and my support for Harvard’s divestment policy, are because “Stavins has done consulting work for Chevron, Exelon, Duke Energy and the Western States Petroleum Association.”

The author of the Huffington Post piece selected those three companies and one trade association from a list of 92 “Outside Activities” that I voluntarily provide as a means of public disclosure. The author chose not to note that the vast majority of my outside engagements are with universities, think tanks, environmental advocacy NGOs, foundations, the U.S. Environmental Protection Agency, other federal agencies and departments, international organizations, and environment ministries around the world (not to mention a set of Major League Baseball teams, but that’s another story altogether).

But what about the four he did choose to highlight? First, I am very proud of my work supported by Chevron and the closely-related Western States Petroleum Association, in which I have carried out a series of analyses studying how to strengthen and improve California’s climate policy under AB-32. That’s right – developing and assessing ways to make the AB-32 cap-and-trade system and the related suite of “complementary policies” more environmentally effective, more cost-effective, and more equitable (I’ve written about this work several times at this blog).

Likewise, my work supported by Duke Energy began a decade ago when I helped the former CEO bring home to his senior management the importance of climate change and the importance of well-designed public policies (in particular, carbon cap-and-trade) to address it. All of my subsequent work supported by Duke Energy likewise has focused on the design of better market-based instruments – cap-and-trade – to reduce CO2 emissions.

And, finally, what about Exelon? This was interesting and important work I carried out with my friend and colleague, MIT Professor Richard Schmalensee, Dean Emeritus of the Sloan School of Management (I wrote about this work at this blog and at the Huffington Post). In 2011, with support from Exelon, Professor Schmalensee and I analyzed EPA’s proposals for new rules to regulate the interstate transport of sulfur dioxide and nitrogen oxides emitted from electric power generation facilities. You can read in detail about our multi-faceted assessment, but the bottom-line is that we provided strong support for a stringent rule. Our brief summary at the University of Pennsylvania’s RegBlog concludes: “In sum, while imposing incremental costs to achieve reductions in SO2 and NOX emissions, the Transport Rule would produce significant benefits in terms of improved health outcomes, and better environmental amenities and services, which studies estimate significantly outweigh the costs.”

Sadness and Empathy

It is nothing less than absurd – and, frankly, quite sad – that someone would suggest that my views on divestment and my New York Times quote on the politics of Keystone XL were somehow due to my having received previous support for analytical work for an oil company, a trade association, and two electric utilities. This was an unfortunate move to question my credibility and damage my reputation in a misguided attempt to demonize me, rather than engage in reasonable discussion and debate. Unfortunately, most of those who have read the activist/journalist’s original commentary and have possibly repeated his claims to others will not see the essay you have just read.

This is surely nothing compared with what Professor Gruber has gone through, but it has certainly increased my empathy for him, as well as my admiration.

Personal Attacks: An Even Sadder Epilogue

It’s nearly two months since I wrote the essay above, but a series of recent events prompts me to add this sad epilogue.  My family and I have recently been subject to cyber-bullying, harassment, and threats, because of my public stance in support of Harvard’s decision not to divest from its endowment portfolio its holdings of fossil-fuel company stocks.

In particular, the most recent message sent to me said in part: “You may be assured that I will have a lot to say about your vocal public support of Harvard’s fossil fuel investments, … and that I have a particular interest in making sure that [your] financial connections to the fossil fuel industry are made fully public …” This threat to tarnish my reputation by publicizing a supposed conflict of interest is striking for a number of reasons:

  • In several essays at this blog and elsewhere, I have carefully explained my reasons for supporting Harvard’s decision not to divest;
  • In several essays at this blog and elsewhere, I have been completely up front about receiving support for (publically available) analytical work I’ve carried out for private-sector companies (and have long provided a list of all outside engagements at my website);
  • In the essay above, I documented the fundamentally pro-environment, policy-analytic work I had done for the specific companies mentioned; and
  • The claim that my position regarding Harvard divestment has somehow been influenced by my work with an oil company and an industry trade association defies logic.

The last item on this list – the fundamental illogic of such a claim – merits explanation. People on all sides of the divestment issue (including leaders of the student movement, and including the person who wrote the threat I quoted above) acknowledge that divestment will have no direct financial impacts on the respective companies. Rather, the merit of divestment that is most frequently cited by supporters is its symbolic value. Because divestment has no financial impacts on the fossil-fuel companies, those companies don’t care much about it. They would not care one way or the other what I might have to say on the topic. Hence, even if I did want to curry favor with those companies, that would not lead me (or anyone else) to take a particular position on the divestment issue.

The more important question to ask is whether my research, teaching, and outreach initiatives on climate change economics and policy have been biased by my having carried out consulting assignments for an oil company and trade association (two of a hundred outside engagements over the past several years)? That is, if there really was a conflict of interest, then in an effort to make those companies happy, I would presumably pull my punches regarding recommendations of what does matter to those companies – public policies that will reduce their profits by increasing their costs of doing business and/or by reducing demand for their products. But nothing could be further from the truth!

For a decade or more, my research, teaching, and outreach have focused on more enlightened, stronger, and better climate change policies. I have been outspoken in regard to the pressing need for well-designed carbon-price instruments at the national and sub-national levels, and for the need for better, more effective international climate policies, both under the United Nations Framework Convention on Climate Change and through other venues. This is reflected in my published research, my teaching, and my outreach efforts, including through this blog.

It is ironic, offensive, and sad that anyone would suggest that my support of Harvard’s divestment position is somehow tied to my outside engagements. That suggestion – and the recent threats I have received – defies logic and is contradicted by the record.

Assessing the Outcome of the Lima Climate Talks

In the early morning hours of Sunday, December 14th, the Twentieth Conference of the Parties (COP-20) of the United Nations Framework Convention on Climate Change (UNFCCC) concluded in Lima, Peru with an agreement among 195 countries, the “Lima Call for Climate Action,” which represents both a classic compromise between the rich and poor countries, and a something of a breakthrough after twenty years of difficult climate negotiations.

Just before two o’clock in the morning, the President of COP-20, Manuel Pulgar Vidal, Peru’s Minister of Environment, gaveled the approval of the text, without dissent. At that moment, the foundation was established for the next major international climate agreement, which – under the auspices of the Durban Platform for Enhanced Action – will be finalized and signed one year from now at COP-21 in Paris, France, for implementation in 2020.

After five days on the ground in Lima, where I participated in a variety of events and met with a diverse set of national negotiating teams, I’ve reviewed the agreed text of the Lima Call for Climate Action (which I abbreviate below as the “Lima decision”), and can now reflect on its gestation, its meaning, and its implications.

The Lima Call for Climate Action

By establishing a new structure in which all countries will state (over the next six months) their contributions to emissions mitigation, this latest climate accord moves the process in a productive direction in which all nations will contribute to the reduction of greenhouse gas emissions.

Working to fulfill the promise made in the 2011 Durban Platform for Enhanced Action to include all parties (countries) under a common legal framework, the Lima decision constitutes a significant departure from the past two decades of international climate policy, which – since the 1995 Berlin Mandate and the 1997 Kyoto Protocol – have featured coverage of only a small subset of countries, namely the so-called Annex I countries (more or less the industrialized nations, as of twenty years ago).

The expanded geographic scope of the Lima Call for Climate Action and thereby the incipient Paris agreement – and the emerging architecture of a pragmatic hybrid combining bottom-up “Intended Nationally Determined Contributions” (INDCs) with top-down elements for reporting and synthesis of contributions by the UNFCCC Secretariat – represents the best promise in many years of a future international climate agreement that is truly meaningful.

Importantly, the Lima decision provides that each country’s INDC shall include a clear statement of emissions mitigation, and may include quantifiable information on reference points (such as base year), time frame of implementation and coverage, assumptions and methodological approaches for estimating and accounting for greenhouse gas emissions, as well as each country’s own assessment of its INDC’s fairness and ambition.  These statements of national contributions are to be submitted by the end of March, 2015, although countries that miss that “deadline” can then make their submissions by June.

Compromises, Compromises

Because of the ongoing sharp divide in climate talks between developed and developing countries, the Lima decision was difficult to accomplish and could only be achieved through compromises that had the effect of watering down various aspects of the accord.  This suggests that the road to Paris may be difficult for the negotiators.

The substitution of the phrase “may include” for “shall include” in regard to the elements of the INDCs was one of the compromises that was necessary to gain the approval of developing countries. So, the U.S.-favored requirement for the use of transparent elements in INDCs that would facilitate comparisons among countries was dropped.

However, at least one negotiating team with whom I met in Lima maintained that the analyses and comparisons of INDCs that will inevitably be carried out by various NGOs and research organizations (including universities) will provide the needed transparency and therefore the needed encouragement to countries for greater ambition.

A review period for the INDCs, favored by the countries most vulnerable to climate change (sub-Saharan Africa and the small island states), was also scrapped. Instead, a synthesis report will be prepared by the UNFCCC Secretariat by November 1st, 2015 (based on INDCs submitted by October 1st).

The Key Roles Played by China and the United States

Throughout the time I was in Lima, it was clear that the joint announcement on November 12th of national targets by China and the United States (under the future Paris agreement) provided necessary encouragement to negotiations that were continuously threatened by the usual developed-developing world political divide.

The delegates from the vast majority of countries were well aware of the fact that the announced China-USA INDCs move the world from the 14% of global CO2 emissions covered by nations participating (a subset of the Annex I countries) in the Kyoto Protocol’s current commitment period to a future Paris agreement that now covers more than 50% of global CO2 emissions, with Europe already on board.

Under the decision text of the Lima Call for Climate Action, within the next six months the other industrialized countries will announce their own contributions, and — more importantly – so will the other large, emerging economies – India, Brazil, Korea, South Africa, Mexico, and Indonesia. Coverage of 80% to 90% of global emissions can be anticipated, although major questions remain regarding what can be expected from some key countries, including India, Russia, and Australia.

Broad, Then Deep

In a 1998 book, edited by Bill Nordhaus (Economics and Policy Issues in Climate Change), Dick Schmalensee wrote about “Greenhouse Policy Architectures and Institutions,” and lamented that the Kyoto Protocol exhibited narrow scope (covering only the Annex I countries) but aggressive ambition for that small set of nations. He presciently noted that this was precisely the opposite of what would be a sensible way forward, namely broad participation, even if the initial ambition is less. Based on the 2011 Durban Platform and the 2014 Lima Call for Climate Action, it now appears that with the 2015 Paris Agreement that approach is finally being adopted.

As I predicted in my previous essay at this blog, in which I previewed the COP-20 talks, the Lima decision will surely disappoint some environmental activists. Indeed, there have already been pronouncements of failure of the Lima/Paris talks from some green groups, primarily because the talks have not and will not lead to an immediate decrease in emissions and will not prevent atmospheric temperatures from rising by more than 2 degrees Celsius (3.6 degrees Fahrenheit), which has become an accepted, but essentially unachievable political goal.

As I said in my previous essay, these well-intentioned advocates mistakenly focus on the short-term change in emissions among participating countries (for example, the much-heralded 5.2% cut by the Annex I countries in the Kyoto Protocol’s first commitment period), when it is the long-term change in global emissions that matters.

They ignore the geographic scope of participation, and do not recognize that — given the stock nature of the problem — what is most important is long-term action.  Each agreement is no more than one step to be followed by others.  And most important now for ultimate success later is a sound foundation, which is what the Lima decision can provide.

Major Challenges Along the Road to Paris

The major sticking points from now until the Paris talks, where it is hoped that the new post-2020 agreement will be signed, are all associated with the divide between rich and poor nations.

The ongoing talks will need to satisfy the interests of both the rich and the poor countries in regard to finance mechanisms, including the realization of the $100 billion commitment that was made in Copenhagen.

Also, looming in the wings is the loss and damage mechanism created in the Warsaw talks last year to help the most vulnerable nations cope with the effects of climate change.  Island nations want that mechanism to become another stream of funding from the rich countries, but the rich countries are concerned that the mechanism might lead to some notion of legal liability (and thereby a blank check).  The loss and damage concept was reiterated (but not expanded) in the Lima decision.

These and other pending issues mean that the upcoming talks in 2015 in Geneva and Bonn, prior to the December 2015 Paris Conference, will continue to require difficult negotiations across the divide between rich and poor countries.

Difficult indeed.  Whereas the agreed decision text from Lima (the “Lima Call for Climate Action”) is less than four pages in length, the Annex (“Elements for a Draft Negotiating Text”) of additional options for the Paris Agreement extends to more than 37 pages!

The Bottom Line

Although it is true that the Lima decision text was watered down in the last 30 hours (as a result of very effective opposition by developing countries), the fact remains that a new way forward has been established in which all countries participate and which therefore holds promise of meaningful global action to address the threat of climate change.  So, despite all the acrimony among parties and the 30-hour delay in completing the talks, the negotiations in Lima these past two weeks may turn out to be a key step along the way.
