What Does the Trump Victory Mean for Climate Change Policy?

Those of you who have read my previous essay at this blog, “This is Not a Time for Political Neutrality” (October 9, 2016), know that my greatest concerns about a Trump presidency (then a possibility, now a certainty), were not limited to environmental policy, but rather were “about what a Trump presidency would mean for my country and for the world in realms ranging from economic progress to national security to personal liberty,” based on his “own words in a campaign in which he substituted impulse and pandering for thoughtful politics” … and “built his populist campaign on false allegations about others, personal insults of anyone who disagrees with him, and displays of breathtaking xenophobia, veiled racism, and unapologetic sexism.”

That’s a broad indictment, to be sure, but whatever real expertise I may have is actually limited to environmental, resource, and energy economics and policy, and so that has and will continue to be the real focus of this blog, “An Economic View of the Environment.” With that in mind, I return today from last month’s brief immersion in partisan politics to discuss climate change policy.

Yesterday, an editor at The New York Times asked me to write a 500-word essay giving my view of what the Trump victory will mean for climate policy. This morning, my very brief essay was published under the headline, “Goodbye to the Climate.” Given the brevity of the piece, it does not touch on many issues and subtleties (I come back to that at the end of today’s blog post), but rather than take the time to expand it, I want to get this to you quickly, and so I am simply reproducing it as it first appeared in the Times (along with an interesting group of other essays, under the overall heading, “What Happened on Election Day: How the election and Donald Trump’s victory looks to Opinion writers.”

Goodbye to the Climate

By Robert N. Stavins

Donald J. Trump once tweeted that “the concept of global warming was created by and for the Chinese in order to make U.S. manufacturing noncompetitive.” Twitter messages may not be clear signs of likely public policies, but Mr. Trump followed up during the campaign with his “America First Energy Plan,” which would rescind all of President Obama’s actions on climate change.

The plan includes canceling United States participation in the Paris climate agreement and stopping all American funding of United Nations climate change programs. It also includes abandoning the Clean Power Plan, a mainstay of the Obama administration’s approach to achieving its emissions reduction target for carbon dioxide under the Paris agreement.

What should we make of such campaign promises? Taking Mr. Trump at his word, he will surely seek to pull the country out of the Paris pact. But because the agreement has already come into force, under the rules, any party must wait three years before requesting to withdraw, followed by a one-year notice period.

Those rules would seem to be mere technicalities. The incoming Trump administration simply can disregard America’s pledge to reduce carbon dioxide emissions by 26 to 28 percent below the 2005 level by 2025. That is bad enough. But the big worry is what other key countries, including the world’s largest emitter, China, as well as India and Brazil, will do if the United States reneges on its pledge. The result could be that the Paris agreement unravels, taking it from the 97 percent of global emissions currently covered by the pact to little more than the European Union’s 10 percent share.

In addition, Mr. Trump’s Environmental Protection Agency probably will stop work on regulations of methane emissions (a very potent greenhouse gas) from existing oil and gas operations. Undoing complex existing regulations, such as the Clean Power Plan, will be more difficult, but a reconstituted Supreme Court will probably help President Trump when that plan inevitably comes before the court. Also, the new president will most likely ask that the Keystone XL pipeline permit application be renewed — and facilitate other oil and gas pipelines around the country.

On the campaign trail, Mr. Trump promised to “bring back” the coal industry by cutting environmental regulations. That may not be so easy. The decline of that industry and related employment has been caused by technological changes in mining, and competition from low-priced natural gas for electricity generation, not by environmental regulations. At the same time, Mr. Trump has pledged to promote fracking for oil and gas, but that would make natural gas even more economically attractive, and accelerate the elimination of coal-sector jobs.

If he lives up to his campaign rhetoric, Mr. Trump may indeed be able to reverse course on climate change policy, increasing the threat to our planet, and in the process destroy much of the Obama legacy in this important realm. This will make the states even more important players on this critical issue.

Given the brevity of the piece, it is not intended to be comprehensive of the many implications for climate change policy of the Trump victory (nor the implications of the Republicans continuing to hold majorities in both houses of Congress).

And I did not get into the many subtleties of the issues I identified. At a bare minimum, these would include:

the possibility of the new administration trying to bypass the four-year delay involved in dropping out of the Paris climate agreement by taking the one-year route of dropping out of the overall United Nations Framework Convention on Climate Change (UNFCCC) – signed by President George H.W. Bush and ratified by the U.S. Senate in 1992;

federal “climate change policies” that have been bipartisan and are therefore much less likely to be repealed, such the latest CAFE and appliance efficiency standards, and the recently extended wind and solar tax credits; and

the myriad of sub-national climate change policies, ranging from AB-32 in California to the Regional Greenhouse Gas Initiative in the northeast (It’s not a coincidence that there’s a high – although not perfect – correlation between the states Secretary Clinton won in the election and the location of the most ambitious climate change policies).

On another occasion, after I’ve had an opportunity to reflect more calmly and carefully on the implications of the forthcoming Trump presidency for environmental, natural resource, and energy policy, I will return to this topic. But for now, I have to prepare for my trip in a few days to Marrakech, Morocco, for the annual UNFCCC negotiations. Given the election results, my meetings there may be quite strange, if not surreal. I hope to write about that in my next essay at this blog.

EPA’s Proposed Greenhouse Gas Regulation: Why are Conservatives Attacking its Market-Based Options?

This week, the Obama Administration’s Environmental Protection Agency (EPA) released its long-awaited proposed regulation to reduce carbon dioxide (CO₂) emissions from existing sources in the electricity-generating sector. The regulatory (rule) proposal calls for cutting CO₂ emissions from the power sector by 30 percent below 2005 levels by 2030.

The Fundamentals in Brief

Through a carefully designed formula, EPA’s proposal lists specific targets for each state, under Section 111(d) of the Clean Air Act. States are given broad flexibility for how to meet their targets, including: increasing the efficiency of fossil-fuel power plants; switching electricity dispatch from coal-fired generating plants to natural gas-fired generating plants; developing new low-emissions generation, such as new natural gas combined cycle plants, more renewable sources (wind and solar), nuclear, or coal with carbon capture and storage; and more efficient end-use of electricity.

States are also given flexibility to employ (in their implementation plans to be submitted to EPA) any of a wide variety of policy instruments, including but by no means limited to market-based trading systems. Furthermore, states can work together to submit multi-state plans.

The proposed regulation will be finalized after receipt of comments one year from now (June 30, 2015). Then states will have until July 2016 to submit their plans, and can request one-year extensions (or two-year extensions for multi-state plans). Compliance commences in 2020.

A Big-Picture Assessment of the Proposed Rule

Let’s start by acknowledging that the proposed policy will be less effective environmentally and less cost-effective economically than the economy-wide approach the Administration previously tried with the Waxman-Markey bill, which passed the U.S. House of Representatives in 2009, but failed to receive a vote in the U.S. Senate. Electricity generation is responsible for about 38 percent of U.S. CO₂ emissions, and about 32 percent of U.S. greenhouse gas (GHG) emissions.

Given ongoing political polarization in Washington and the inability of Congress to approve that more comprehensive and more cost-effective approach, this is probably the best the administration could do. Together with the motor-vehicle fuel efficiency and appliance energy efficiency standards previously put in place, this is certainly a step in the right direction.

More broadly, the importance of these U.S. moves in the international context should not be underestimated. Although the United States accounts for only about 17% of global CO₂ emissions (second to China’s 26% in 2010), these steps by the U.S. government can help international efforts to bring the large emerging economies (China, India, Brazil, Korea, South Africa, and Mexico) on board for a future (Paris, 2015) agreement under the Durban Platform for Enhanced Action.

Domestically, EPA’s proposed state-by-state approach does not guarantee cost-effectiveness, because under the formula employed, marginal abatement costs will initially vary across states. However, freedom is given to the states to employ market-based instruments, in particular, cap-and-trade systems (with carbon taxes presumably also an option). And EPA has emphasized its willingness to consider multi-state implementation plans (think, for example, of the existing Regional Greenhouse Gas Initiative – RGGI – the cap-and-trade system operating in nine northeast states; and the likelihood of a future linked policy bringing together California’s AB-32 cap-and-trade system with policies in Oregon and Washington).

The ability of states to develop under EPA’s rule such linked systems of market-based instruments, as well as the freedom for states and regions to subsequently establish linkages means that although EPA may not be guaranteeing cost-effectiveness, it is certainly allowing for it, indeed it is facilitating it.

Response from Environmental Advocacy Groups and Industry

Much of the response this week has not been surprising. The major environmental advocacy groups have been supportive of the proposed rule, despite the fact that they would prefer even greater ambition. Many in industry have also offered praise for the approach, particularly because of the flexibility that EPA has given for the means of achieving emissions reductions. In fact, some electricity-sector executives have been supportive, precisely for this reason, and appear to be encouraging the adoption of cap-and-trade systems. At a minimum, leading electric utilities, including some that are fossil-heavy, such as FirstEnergy Corporation and American Electric Power, Inc., have taken a “wait-and-see” attitude, rather than attacking the proposal.

Also not surprising has been strong opposition from the coal industry, as well as some prominent industry trade associations, including the U.S. Chamber of Commerce. Once the rule has become final (about a year from now), lawsuits will surely be filed by some of these private industry opponents and by a number of resistant states.

I will leave it to the lawyers to comment on the likely grounds of those anticipated lawsuits, as well as their probabilities of success. But, clearly, for the plan to succeed it will need to survive those legal challenges, which will work their way through the courts over several years.

Also, a significant change in the senate majority and in the party holding power after the next presidential election could result in progress being slowed to a crawl, if not the abandonment of the approach proposed by the current administration.

None of that is particularly surprising, but what should be surprising is the fact that conservative attacks on EPA’s proposed rule have focused, indeed fixated, on one of the options that is given to the states for implementation, namely the use of market-based instruments, that is, cap-and-trade systems. Given the demonization of cap-and-trade as “cap-and-tax” over the past few years by conservatives, why do I say that this fixation should be surprising?

The Irony of Conservatives Targeting Cap-and-Trade

Not so long ago, cap-and-trade mechanisms for environmental protection were popular in Congress. Now, such mechanisms are denigrated. What happened? Professor Richard Schmalensee (MIT) and I recently told the sordid tale of how conservatives in Congress who once supported cap and trade had come to lambast climate change legislation as “cap-and-tax.” Ironically, in doing this, conservatives have chosen to demonize their own market-based creation.

In the late 1980s, there was growing concern that acid precipitation – the result of SO₂ and, to a lesser extent, nitrogen oxides (NOx) reacting in the atmosphere to form sulphuric and nitric acids – was damaging forests and aquatic ecosystems, particularly in the northeast U.S. and southern Canada. In response, the U.S. Congress passed (and President George H.W. Bush signed into law) the Clean Air Act Amendments of 1990. Title IV of this law established the SO₂ allowance-trading system.

By the close of the 20th century, the SO₂ allowance-trading system had come to be seen as both innovative and successful. However, the successful enactment and implementation of the SO₂ cap-and-trade system in 1990 combined with the subsequent Congressional defeat of CO₂ cap-and-trade legislation 20 years later has produced a striking irony. Market-based, cost-effective policy innovation in environmental regulation – in particular, cap-and-trade – was originally championed and implemented by Republican administrations from that of President Ronald Reagan to that of President George W. Bush. But in recent years, Republicans have led the way in demonizing cap-and-trade, particularly as an approach to limiting carbon emissions.

For a long time, market-based approaches to environmental protection, such as cap-and-trade, bore a Republican label. In the 1980s, President Ronald Reagan’s EPA put in place a trading program to phase out leaded gasoline. It produced a more rapid elimination of leaded gasoline from the marketplace than had been anticipated, and at a saving of some $250 million per year, compared with a conventional no-trade, command-and-control approach. Not only did President George H.W. Bush successfully propose the use of cap-and-trade to cut SO₂ emissions, his administration advocated in international forums the use of emissions trading to cut global CO₂ emissions (a proposal initially resisted but ultimately adopted by the European Union). In 2005, President George W. Bush’s EPA issued the Clean Air Interstate Rule, aimed at reducing SO₂ emissions by a further 70% from their 2003 level. Cap-and-trade was again the policy instrument of choice.

From Bi-Partisan Support to Ideological Polarization

When the Clean Air Act Amendments were being considered in the Congress in 1989-1990, political support was not divided on partisan lines. Indeed, environmental and energy debates from the 1970s through much of the 1990s typically broke along geographic lines, rather than partisan lines, with key parameters being degree of urbanization and reliance on specific fuel types. Thus, the Clean Air Act Amendments of 1990 passed the Senate by a vote of 89-11 with 87% of Republican members and 91% of Democrats voting yea, and passed the House of Representatives by a vote of 401-21 with 87% of Republicans and 96% of Democrats voting in support.

But twenty years later, when climate change legislation was receiving serious consideration in Washington, environmental politics had changed dramatically, with Congressional support for environmental legislation coming mainly to reflect partisan divisions. In 2009, the House of Representatives passed the American Clean Energy and Security Act of 2009 (H.R. 2454) – the Waxman-Markey bill – that included an economy-wide cap-and-trade system to cut CO₂ emissions. The Waxman-Markey bill passed the House by a narrow margin of 219-212, with support from 83% of Democrats, but only 4% of Republicans. In July 2010, the Senate abandoned its attempt to pass companion legislation. In the process of debating this legislation, conservatives (largely Republicans and some coal-state Democrats) attacked the cap-and-trade system as “cap-and-tax,” much as an earlier generation of liberals had denigrated cap-and-trade as “selling licenses to pollute.”

It may be that some conservatives in Congress opposed climate policies because of disagreement about the threat of climate change or the costs of the policies, but instead of debating those risks and costs, they chose to launch an ultimately successful campaign to demonize and thereby tarnish cap-and-trade as an instrument of public policy, rendering it “collateral damage” in the wider climate policy battle.

Today that “scorched-earth” approach may have come back to haunt conservatives. Have they now boxed themselves into a corner, unable to support the power of the marketplace to reduce their own states’ compliance costs under the new EPA CO₂ regulation? I hope not, but only time will tell.

Economics and Politics in California: Cap-and-Trade Allowance Allocation and Trade Exposure

In my previous essay at this blog – The Importance of Getting it Right in California – I wrote about the precedents and lessons that California’s Global Warming Solutions Act (AB 32) and its greenhouse gas (GHG) cap-and-trade system will have for other jurisdictions around the world, including other states, provinces, countries, and regions. This is particularly important, given the failure of the U.S. Senate in 2009 to pass companion legislation to the Waxman-Markey bill, passed by the U.S. House of Representatives, highlighting the absence of a national, economy-wide carbon pricing policy.

In my previous essay, I focused on three pending design issues in the emerging rules for the AB-32 cap-and-trade system: (1) the GHG allowance reserve; (2) the role of offsets; and (3) proposals for allowance holding limits. I drew upon a presentation I made on “Offsets, Holding Limits, and Market Liquidity (and Other Factors Affecting Market Performance)” at the 2013 Summer Issues Seminar of the California Council for Environmental and Economic Balance.

At the same conference, I made another presentation, which was on “Allowance Value Distribution and Trade Exposure,” a topic that is of great importance both economically and politically, not only in the context of the design of California’s AB-32 cap-and-trade system, but for the design of any cap-and-trade instrument in any jurisdiction. It is to that topic that I turn today. (For a much more detailed discussion, please see a white paper I wrote with Dr. Todd Schatzki of Analysis Group, “Using the Value of Allowances from California’s GHG Cap-and-Trade System,” August, 2012).

Why Does Anyone Care About the Allowance Value Distribution?

A cap-and-trade policy creates a valuable new commodity – emissions allowances. In a well-functioning emissions trading market, the financial value of these allowances (per ton of emissions, for example) is approximately equivalent to their opportunity cost, which is the marginal cost of emissions reductions. This is because of the existence of the overall cap, which – if binding – fosters scarcity of available allowances, and hence generates their economic value.

It should not be surprising, then, that the initial allocation of these allowances can have important consequences both for environmental and for economic outcomes.

Environmental Consequences of the Initial Allowance Allocation

No matter how many times I meet with policy makers around the world to talk about alternative policy instruments (for climate change and other environmental problems), I never cease to be struck by the confusion that abounds regarding the environmental (and the economic) consequences of the initial allocation of allowances in a cap-and-trade system. As I have written many times in the past at this blog, the initial allocation does not directly affect environmental outcomes. Regardless of the allocation method used, aggregate emissions are limited by the emissions cap. This is true whether the allowances are sold (auctioned) or distributed without charge. Furthermore, which firms or sources receive the initial allocation of allowances has no effect on either aggregate emissions or the ultimate distribution of emissions reductions among sources.

This independence of a cap-and-trade system’s performance from the initial allowance allocation was established as far back as 1972 by David Montgomery in a path-breaking article in the Journal of Economic Theory (based upon his 1971 Harvard economics Ph.D. dissertation). It has been validated with empirical evidence repeatedly over the years. (More below about the initial allocation’s potential effects on economic performance.)

However, it is also true that the initial allocation method can indirectly affect emissions. In particular, emissions leakage can arise if economic activity shifts to unregulated sources – this risk is greatest with auctions or free fixed allocations. In contrast, an updating, output-based allocation (used in AB 32 for “industry assistance”) can reduce leakage risk by making the free allocation of allowances marginal, rather than infra-marginal (as is the case with a simple free allocation).

Economic Consequences of the Initial Allowance Allocation

A favorite topic of academic economists is that the allowance allocation method in a cap-and-trade system can affect the overall social cost of the policy if the allowances are auctioned (sold by government to compliance entities), and if the revenues are then used to reduce distortionary taxes (such as taxes on labor and investment), thereby eliminating some deadweight loss and cutting overall social cost. I discuss this a bit more below, but for now let’s recognize that the combination of two California propositions and subsequent court rulings means that the State is not permitted to use the auction proceeds to cut taxes (rather, any auction proceeds must be used to achieve the purposes of AB 32, that is, reducing GHG emissions).

So, within the set of feasible options, the initial allowance allocation will not directly affect the cost-effectiveness of actions taken by emission sources to reduce emissions. In other words, aggregate abatement costs will not be directly affected by the nature of the initial allocation.

I was careful to use the word, “directly,” because the initial allowance allocation can indirectly affect economic outcomes. In particular, the use of updating, output-based allocations can: (1) lower the costs seen by consumers, which can reduce incentives to conserve; (2) avoid reductions in economic activity within California, with associated distributional impacts; and (3) avoid potential shifts of production to less efficient, more distant producers.

Auction Revenue Use

Decisions about how auction revenues are used can have profound consequences for the potential benefits of auctioning. There are three basic options.

First, as I emphasized above, in theory, reducing distortionary taxes provides the greatest net economic benefit (by reducing the social cost of the policy). But California’s unique legal context takes this option off the table.

Second, funding programs to address other market failures that are not addressed by the price signals provided by the cap-and-trade system can be meritorious. For example, information spillovers can be addressed through financing of research and development activities, and the principal-agent problems that infect energy-efficiency adoption decisions in rental properties can be addressed — to some degree — through zoning and other local policies.

The third and final option, however, is highly problematic, if not completely without merit, and yet, ironically, there are strong incentives in place for policy makers to go this third route. This third option is to use auction revenues to fund programs to subsidize emission reductions. There is a strong incentive to do this, because of California’s legal constraint to employ any auction revenues in pursuit of the objectives of the statute, that is, reducing GHG emissions.

What’s the problem? The AB-32 cap-and-trade system will cover approximately 85% of the economy. In other words, the vast majority of sources are under the cap. As I have explained in detail in several previous essays at this blog, under the umbrella of a cap-and-trade mechanism, (successful) efforts to further reduce emissions of capped sources will have three consequences: (1) allowance prices will be supressed (take a look at the hand-wringing in Europe over allowance prices in its CO₂ Emissions Trading System); (2) aggregate compliance costs will be increased (cost-effectiveness is reduced because marginal abatement costs are no longer equated among all sources); and (3) nothing is accomplished for the environment, in the sense that there are no additional CO₂ emissions reductions (rather, the CO₂ emissions reductions are simply relocated among sources under the cap).

Economics, Policy, and Politics

As I concluded in my previous essay, the California Air Resources Board has done an impressive job in its initial design of the rules for its GHG cap-and-trade system. Of course, there are flaws, and therefore there are areas for improvement. A major issue continues to be the mechanisms used for the initial allocation of allowances. Because of the economics and politics of this issue, it will not go away. But, going forward, it would be helpful if those debating this issue could demonstrate better understanding of the allowance allocation’s real – as opposed to fictitious – environmental and economic consequences.
