Early Impacts of Trump 2.0 on Domestic Climate Policy

In my podcast series, “Environmental Insights: Conversations on Policy and Practice from the Harvard Environmental Economics Program,” I’ve had the pleasure of engaging in conversations with environmental economics scholars who have also had significant experience in the policy world.  My guest in the most recent episode is a great example of this, because I was joined by Joseph Aldy, my colleague at the Harvard Kennedy School, where he is the Teresa and John Heinz Professor of the Practice of Environmental Policy.  Joe’s research focuses on climate change policy, energy policy, and regulatory policy, and, importantly, from 2009 to 2010, Joe served as Special Assistant to President Barack Obama for Energy and Environment, which game him significant experience both in the economics and the politics of climate change policy.  You can listen to our complete conversation here.

This was Joe’s second visit to the podcast, the first having been in November of 2019, in what was the 7th of 66 episodes we’ve now produced.  I believe he was the first guest to come back for a return visit, and the reason why I double-dipped was that when I decided to ask someone to assess what has happened and will happen in the second Trump administration’s first 100 days, particularly in regard to domestic environmental, energy, and climate policy, Joe Aldy was my first choice.  (I emphasize domestic policy, because I’ve already written in two recent blog essays about what to expect in the international domain, but not in the domestic domain:  The Evolving China-USA Climate Policy Relationship; and What Trump’s Exit from the Paris Agreement Will Really Mean.)

We’re about half-way through the first 100 days of this new administration (although it feels like it’s already been several years).  So, before we discussed Joe Aldy’s expectations for the next two to four years, we focused on what has already happened. 

Aldy begins by describing how the Trump administration has moved quickly on many fronts using numerous executive orders, rolling back regulatory policies, and creating a National Energy Dominance Council to confront what it has termed a “national energy emergency.” 

“It’s a little bit of a challenge to say we’re actually dealing with a kind of energy emergency that was described by the President because we’re producing more energy now than we ever have.  When we look at the fact that we’re at record highs in oil production, gas production, and renewable power production on the supply side, we’re not necessarily facing what one might think of as an emergency when it comes to energy.”

Aldy goes on to note that he is alarmed, however, by some of the brazen early moves the administration is making in the energy and climate space.

“We see efforts going on now that I think are potentially more fundamental in undermining the ability of the federal government to regulate greenhouse gas emissions. Tasked on day one to EPA was to assess the prospect of undoing the Endangerment Finding under the Clean Air Act. That’s the necessary foundation [for] the EPA [to exercise its] authority to regulate greenhouse gas emissions,” he says. “They’re moving in that direction, and a lot of this is going to end up in the courts.”

But Joe contends that the courts may not be so sympathetic toward the administration. 

“Part of the response from those who want to slow this kind of retrenchment when it comes to clean energy and climate policy is to litigate, and some of what is happening is happening so fast. I mean, we saw this in Trump 1.0 where some things they try to do very quickly. What they did was not consistent with the process that is established under law that you’re supposed to follow, or you will be found to have been in the language of the Administrative Procedure Act that governs how we implement the administrative state, ‘arbitrary and capricious.’ You lose in the courts on process grounds, not even on the merits.”

Aldy also argues that the administration seems to be pursuing a number of countervailing objectives using a variety of tools that will cause unintended consequences.

“The prospect of tariffs generally really interact with an agenda focused on trying to advance oil and gas development in the United States. If we are going to put tariffs on imported steel [the price of oil extraction will go up],” he remarks. “So, [when] importing crude oil, natural gas, or electricity from Canada… with tariffs, [it will] make [those] more expensive domestically and affect… both the business case for using energy as well as the domestic politics about energy.”

The clean energy tax credits contained in the Inflation Reduction Act may also be in jeopardy, Aldy observes, although he admits there may be pushback from some Republicans representing areas where the tax credits have positive economic impact. And those may be key votes, Aldy says, when the president’s proposed tax cuts come before Congress.

“I think there were more than a dozen Republicans who voted against the tax bill, the Trump tax cuts of 2017, in the House of Representatives. They can’t lose a dozen votes this time. It’s a much tighter margin. And so, there’s a question about, is there sufficient support for sustaining at least some clean energy tax credits going forward?”

Importantly, Joe notes that even if the administration is successful in efforts to slow down the clean energy transition, it won’t be able to stop it altogether.

“The clean energy economy in the U.S. is so much more advanced now that signing executive orders doesn’t affect the 30-plus gigawatts of solar that was installed last year. It doesn’t affect the fact that we have been installing more wind power every year for the past decade than we have natural gas in terms of incremental capacity investment. All… the people who recently bought EVs, they’re still going to drive their EVs. We’re still going to produce power from these renewable power facilities,” he argues.

“I think that we’re going to see more and more business investment, because the business case for clean energy is getting better and better, even if the policy environment is getting more uncertain,” he says. “It means that the worst-case scenario, at least in terms of what happens to our emissions and our energy economy, is basically like stasis. We need to accelerate if we’re going to be up to the challenge of the problem, but I think we will just find ourselves treading water for a while. The challenge is whether or not there’s really bad spillovers to other countries.”

A Golden Opportunity to Please Conservatives and Liberals Alike

The U.S. Environmental Protection Agency (EPA) has a golden opportunity to opt for a smart, low-cost approach to fulfilling its mandate under a Supreme Court decision to reduce carbon dioxide (CO2) and other greenhouse gas (GHG) emissions linked with global climate change.

Such an approach would provide maximum compliance flexibility to private industry while meeting mandated emission reduction targets, would achieve these goals at the lowest possible cost, would work through the market rather than against it, would be consistent with the Obama Administration’s pragmatic approach to environmental regulation, and ought to receive broad political support, including from conservatives, who presumably want to minimize the cost burden of any policy on businesses and consumers.

Background and Context

By now, it is well known that the 2007 U.S. Supreme Court (5-4) decision in Massachusetts v. EPA found that EPA has the authority to regulate GHGs under the existing provisions of the Clean Air Act (CAA). This, combined with EPA’s “endangerment finding” in 2009 that GHGs threaten public health and the environment, led first in January, 2011, to new motor vehicle fuel efficiency standards, and soon will lead to regulations affecting new and modified stationary sources of emissions (under Section 111b of the CAA) via so-called New Source Performance Standards, and regulations for existing stationary sources (under Section 111d).

In quantitative terms, this last set of regulations – for existing stationary sources – will be key, and by far the most important affected sector will be electricity generation, which accounts for fully 40 percent of U.S. CO2 emissions (and a third of national GHG emissions). Within this sector, coal-fired power plants will be the most drastically affected.

EPA could, in principle, promulgate a regulatory approach that incorporates compliance flexibility, such as through various types of credit, offset, or cap-and-trade mechanisms. It could do this, but may it do so under the legal authority of the Clean Air Act?

Call the Lawyers!

Over the past year, there has been a considerable amount of discussion and no small degree of hand-wringing over whether the relevant parts of the Clean Air Act authorize the use of such flexibility mechanisms. In the midst of this, a new report from Resources for the Future by Gregory Wannier (Columbia Law School) and others makes a compelling, but nuanced case in the affirmative. (See “Prevailing Academic View on Compliance Flexibility under §111 of the Clean Air Act”).

Their conclusion, in a nutshell: “EPA has the tools under §111 of the CAA to implement relatively flexible and efficient GHG regulation. The agency could use a range of compliance flexibility options itself, or facilitate state implementation plans that adopt such measures at the state or regional level.” Included are the market-based, economic-incentive instruments mentioned above.

We should take note, by the way, that Section 111d gives states considerable latitude when choosing their actions to follow EPA guidelines, an approach that is consistent with conservatives’ promotion of the primacy of state authorities in tailoring rules for individual state-by-state circumstances.

Now, for Some Economics

Even if the EPA has the legal authority to adopt a progressive, market-based approach to fulfilling this regulatory mandate, would it really make sense to do this? That is, what would be the consequences of adopting a flexible approach, compared with a conventional, inflexible regulatory scheme? Key issues include the implications for environmental performance, aggregate social cost, and consumer impacts via electricity prices.

Another new study, this one by Dallas Burtraw, Anthony Paul, and Matt Woerman (all at RFF), provides the analysis that is needed, using RFF’s well-regarded Haiku model of the U.S. electricity market, to examine the effect of alternative CAA policies on investment and operation of the nation’s electricity system over a 25-year time horizon in 21 interlinked regions. (See: “Retail Electricity Price Savings from Compliance Flexibility in GHG Standards for Stationary Sources”)

Four scenarios which would achieve the same environmental benefits are examined:

(1) a conventional approach in which the operating efficiency of individual coal-fired power plants would be regulated (labeled an “inflexible performance standard”).

(2) a “flexible performance standard,” under which plants that exceeded the standard could transfer a credit (in exchange for payment) to plants that found it more difficult to achieve the standard. The researchers call these “generation efficiency credit offsets.”

(3) cap-and-trade with auctioned CO2 emission allowances, where the revenue generated for government simply displaces the need for other revenue sources on a one-for-one basis (that is, there is no assumption of a double-dividend through increased efficiency of the tax code).

(4) cap-and-trade with free allocation of allowances to Local Distribution Companies (LDCs), which are regulated and hence assumed to pass the benefits of the free allocation on to consumers.

The results are striking. In terms of aggregate social costs, the inflexible standard would bring with it total costs of about $5 billion per year, whereas – at the other extreme – cap-and-trade with free allocation would involve total costs of only $500 million annually, a 90 percent cost savings!

If – despite its legal authority – EPA believes it is politically unable to adopt a cap-and-trade approach (because of last year’s successful tarnishing of that phrase by Congressional conservatives), then it could opt for a second-best approach, the “flexible-performance standard,” above, which would involve total annual costs of about $1.4 billion, still a 70 percent cost savings compared with the conventional, inflexible standard.

Of course, political consideration of such policy alternatives is more frequently driven by estimates of consumer impacts than by overall social costs (which include consumer costs, industry costs, and costs to government). Here, the analysis is also striking. Consumer costs – due to higher electricity prices – under the inflexible standard would increase by 7 percent, while consumer costs under the flexible performance standard would increase by less than 2 percent. With the cap-and-trade regime with free allowances, consumer costs would actually fall by nearly 1 percent, due to lower electricity prices. [For complete numerical results with all of the scenarios, see the RFF discussion paper.]

The Bottom Line

Clearly, much is to be gained – and virtually nothing lost – by adopting a more flexible approach to meeting a court-ordered mandate that, one way or another, will have a regulation promulgated and eventually finalized. It would be foolish to turn away from a potential 90 percent cost savings for the country’s economy, particularly when the same approach yields lower electricity prices for consumers. All this, while meeting national obligations to reduce greenhouse gas emissions.

It’s too soon to forget that a year ago the Senate abandoned its attempt to pass climate legislation that would limit CO2 emissions. In the process, conservative Republicans dubbed cap-and-tradecap-and-tax.’’ But, as I’ve said before, regardless of what they think about climate change, conservatives should resist demonizing market-based approaches to environmental protection and reverting to pre-1980s thinking that saddled business and consumers with needless costs.

Market-based approaches to environmental protection should be lauded, not condemned, by political leaders, no matter what their party affiliation. Otherwise, there will be severe and perverse long-term consequences for the economy, for business, and for consumers.

AB 32, RGGI, and Climate Change: The National Context of State Policies for a Global Commons Problem

Why should anyone be interested in the national context of a state policy?  In the case of California’s Global Warming Solutions Act (AB 32), the answer flows directly from the very nature of the problem — global climate change, the ultimate global commons problem.  Greenhouse gases (GHGs) uniformly mix in the atmosphere.  Therefore, any jurisdiction taking action — whether a nation, a state, or a city — will incur the costs of its actions, but the benefits of its actions (reduced risk of climate change damages) will be distributed globally.  Hence, for virtually any jurisdiction, the benefits it reaps from its climate‑policy actions will be less than the cost it incurs.  This is despite the fact that the global benefits of action may well be greater — possibly much greater — than global costs.

This presents a classic free-rider problem, in which it is in the interest of each jurisdiction to wait for others to take action, and benefit from their actions (that is, free-ride).  This is the fundamental reason why the highest levels of effective government should be involved, that is, sovereign states (nations).  And this is why international, if not global, cooperation is essential. [See the extensive work in this area of the Harvard Project on International Climate Agreements.]

Despite this fundamental reality, there can still be a valuable role for sub-national climate policies.  Indeed, my purpose in this essay is to explore the potential for such state and regional policies — both in the presence of Federal climate policy and in the absence of such policy.  I begin by describing the national climate policy context, and then turn to sub-national policies, such as California’s AB 32 and the Regional Greenhouse Gas Initiative (RGGI) in the northeast.  My focus is on how these sub-national policies will interact with a Federal climate policy.  It turns out that some of the interactions will be problematic, others will be benign, and still others could be positive.  I also examine the role that could be played by sub-national policies in the absence of a meaningful Federal policy, with the conclusion that — like it or not — we may find that Sacramento comes to take the place of Washington as the center of national climate policy.

The (Long-Term) National Context:  Carbon-Pricing

I need not tell readers of this blog that virtually all economists and most other policy analysts favor a national carbon‑pricing policy (whether carbon tax or cap-and-trade) as the core of any meaningful climate policy action in the United States.  Why is this approach so overwhelmingly favored by the analytical community?

First, no other feasible approach can provide truly meaningful emissions reductions (such as an 80% cut in national CO2 emissions by mid-century).  Second, it is the least costly approach in the short term, because abatement costs are exceptionally heterogeneous across sources.  Only carbon-pricing provides strong incentives that push all sources to control at the same marginal abatement cost, thereby achieving a given aggregate target at the lowest possible cost.  Third, it is the least costly approach in the long term, because it provides incentives for carbon-friendly technological change, which brings down costs over time.  Fourth, although carbon pricing is not sufficient on its own (because of other market failures that reduce the impact of price signals — more about this below), it is a necessary component of a sensible climate policy, because of factors 1 through 3, above.  [I’ve written about carbon-pricing in many previous blog posts, including on June 23, 2010, “The Real Options for U.S. Climate Policy.”]

But carbon-pricing is a hot-button political issue.  This is primarily because it makes the costs of the policy transparent, unlike conventional policy instruments, such as performance and technology standards, which tend to hide costs.  Carbon-pricing is easily associated with the dreaded T-word.  Indeed, in Washington, cap-and-trade has been successfully demonized as “cap-and-tax.” As a result, the political reality now appears to be that a national, economy-wide carbon-pricing policy is unlikely to be enacted before 2013.  Does this mean that there will be no Federal climate policy in the meantime?  No, not at all.

The (Short-Term) National Context:  Federal Regulations on the Way or Already in Place

Regulations of various kinds may soon be forthcoming — and in some cases, will definitely be forthcoming — as a result of the U.S. Supreme Court decision in Massachusetts v. EPA and the Obama administration’s subsequent “endangerment finding” that emissions of carbon dioxide and other greenhouse gases endanger public health and welfare.  This triggered mobile source standards earlier this year, the promulgation of which identified carbon dioxide as a pollutant under the Clean Air Act, thereby initiating a process of using the Clean Air Act for stationary sources as well.

Those new standards are scheduled to begin on January 2, 2011, with or without the so‑called “tailoring rule” that would exempt smaller sources.  Among the possible types of regulation that could be forthcoming for stationary sources under the Clean Air Act are:  new source performance standards; performance standards for existing sources (Section 111(d)); and New Source Review with Best Available Control Technology standards under Section 165.

The merits that have been suggested of such regulatory action are that it would be effective in some sectors, and that the threat of such regulation will spur Congress to take action with a more sensible approach, namely, an economy-wide cap‑and‑trade system.  However, regulatory action on carbon dioxide under the Clean Air Act will accomplish relatively little and do so at relatively high cost, compared with carbon pricing.  Also, it is not clear that this threat will force the hand of Congress; it clearly has not yet done so.  Indeed, it is reasonable to ask whether this is a credible threat, or will instead turn out to be counter‑productive (when stories about the implementation of inflexible, high‑cost regulatory approaches lend ammunition to the staunchest opponents of climate policy).

It’s also possible that air pollution policies for non‑greenhouse gas pollutants, the emissions of some of which are highly correlated with CO2 emissions, may play an important role.  For example, three‑pollutant legislation focused on SOx, NOx, and mercury could have profound impacts on the construction and operation of coal‑fired electricity plants, without any direct CO2 requirements.  Without any new legislation, a set of rules which could have significant impacts on coal-fired power plants are now making their way through the regulatory process — including regulations affecting ambient ozone, SO2/NO2, particulates, ash, hazardous air pollutants (mercury), and effluent water.

There is also the possibility of new energy policies (not targeted exclusively at climate change) having significant impacts on CO2 emissions.  The possible components of such an approach that would be relevant in the context of climate change include:  a national renewable electricity standard; Federal financing for clean energy projects: energy efficiency measures (building, appliance, and industrial efficiency standards; home retrofit subsidies; and smart grid standards, subsidies, and dynamic pricing policies); and new Federal electricity‑transmission siting authority.

Even without action by the Congress or by the Administration, legal action on climate policy is likely to take place within the judicial realm.  Public nuisance litigation will no doubt continue, with a diverse set of lawsuits being filed across the country in pursuit of injunctive relief and/or damages.  Due to recent court decisions, the pace, the promise, and the problems of this approach remain uncertain.

Beyond the well‑defined area of public nuisance litigation, other interventions which are intended to block permits for new fossil energy investments, including both power plants and transmission lines will continue.  Some of these interventions will be of the conventional NIMBY character, but others will no doubt be more strategic.

But with political stalemate in Washington on carbon-pricing or national climate policy, attention is inevitably turning to regional, state, and even local policies intended to address climate change.

Sub-National Climate Policies

The Regional Greenhouse Gas Initiative (RGGI) in the Northeast has created a cap‑and‑trade system among electricity generators.  More striking, California’s Global Warming Solutions Act (Assembly Bill 32, or AB 32) will likely lead to the creation of a very ambitious set of climate initiatives, including a statewide cap‑and‑trade system (unless it’s stopped by ballot initiative — Proposition 23 — or a new Governor, depending on the outcome of the November 2010 elections).  The California system is likely to be linked with systems in other states and Canadian provinces under the Western Climate Initiative.  Currently, more than half of the 50 states are contemplating, developing, or implementing climate policies.

In the presence of a Federal policy, will such state efforts achieve their objectives?  Will the efforts be cost-effective?  The answer is that the interactions of state policies with Federal policy can be problematic, benign, or positive, depending upon their relative scope and stringency, and depending upon the specific policy instruments used.  This is the topic of a paper which Professor Lawrence Goulder (Stanford University) and I have written, “Interactions Between State and Federal Climate Change Policies” (National Bureau of Economic Research Working Paper 16123, June 2010).

Problematic Interactions

Let’s start with the case of a Federal policy which limits emission quantities (as with cap-and-trade) or uses nationwide averaging of performance (as with some proposals for a national renewable portfolio standard).  In this case, emission reductions accomplished by a “green state” with a more stringent policy than the Federal policy — for example, AB 32 combined with Waxman-Markey/H.R. 2454 — will reduce pressure on other states, thereby freeing, indeed encouraging (through lower allowance prices) emission increases in the other states.  The result would be 100% leakage, no gain in environmental protection from the green state’s added activity, and a national loss of cost-effectiveness.

Potential examples of this — depending upon the details of the regulations — include: first, AB 32 cap-and-trade combined with Federal cap-and-trade (H.R. 2454) or combined with some U.S. Clean Air Act performance standards; second, state limits on GHGs/mile combined with Federal CAFE standards; and third, state renewable fuels standards combined with a Federal RFS, or state renewable portfolio standards combined with a Federal RPS.  A partial solution would be for these Federal programs to allow states to opt out of the Federal policy if they had an equally or more stringent state policy.  Such a partial solution would not, however, be cost-effective.

Benign Interactions

One example of benign interactions of state and Federal climate policy is the case of the Regional Greenhouse Gas Initiative (RGGI) in the northeast.  In this case, the state policies are less stringent than an assumed Federal policy (such as H.R. 2454).  The result is that the state policies become non-binding and hence largely irrelevant.

A second example — that warms the hearts of economists, but appears to be politically irrelevant for the time being — is the case of a Federal policy that sets price, not quantity, i.e., a carbon tax, or a binding safety-valve or price collar in a cap-and-trade system.  In this case, more stringent actions in green states do not lead to offsetting emissions in other states induced by a changing carbon price.  It should be noted, however, that there will be different marginal abatement costs across states, and so aggregate reductions would not be achieved cost-effectively.

Positive Interactions

Three scenarios suggest the possibility of positive interactions of state and Federal climate policies.  First, states can — in principle — address market failures not addressed by a Federal carbon-pricing policy.  A prime example is the principal‑agent problem of insufficient energy‑efficiency investments in renter‑occupied properties, even in the face of high energy prices.  This is a problem that is best addressed at the state or even local level, such as through building codes and zoning.

Second, state and regional authorities frequently argue that states can serve as valuable “laboratories” for policy design, and thereby provide useful information for the development of Federal policy.  However, it is reasonable to ask whether state authorities will allow their “laboratory” to be closed after the experiment has been completed, the information delivered, and a Federal policy put in place.  Pronouncements from some state leaders should cause concern in this regard.

Third, states can create pressure for more stringent Federal policies.  A timely example is provided by California’s Pavley I motor-vehicle fuel-efficiency standards and the subsequent change in Federal CAFE requirements.  There is historical validation of this effect, with California repeatedly having increased the stringency of its local air pollution standards, followed by parallel Federal action under the Clean Air Act.  This linkage is desirable if the previous Federal policy is insufficiently stringent, but whether that is the case is an empirical question.

Thus, in the presence of Federal climate policy, interactions with sub-national policies can be problematic, benign, or positive, depending upon the relative scope and stringency of the sub-national and national policies, as well as the particular policy instruments employed at both levels. [For a more rigorous derivation of the findings above, as well as an examination of a larger set of examples, please see my paper with Stanford Professor Lawrence Goulder, referenced above.]

But comprehensive Federal carbon-pricing policy appears to be delayed until 2013, at the earliest.  And it is possible that pending Federal regulatory action under the Clean Air Act will be curtailed or significantly delayed either by the new Congress or by litigation.  Therefore, it is important to consider the role of state and regional climate policies in the absence of Federal action.

Sub-National Climate Policies in the Absence of Federal Action

In brief, in the absence of meaningful Federal action, sub‑national climate policies could well become the core of national action.  Problems will no doubt arise, including legal obstacles such as possible Federal preemption or litigation associated with the so‑called Dormant Commerce Clause.

Also, even a large portfolio of state and regional policies will not be comprehensive of the entire nation, that is, not truly national in scope (for a quick approximation of likely coverage, check out a recent map of blue states and red states).

And even if the state and regional policies were nationally comprehensive, there would be different policies of different stringency in different parts of the country, and so carbon shadow‑prices would by no means be equivalent, meaning that the overall policy objectives would be achieved at excessive social cost.

Is there a solution (if only a partial one)?  Yes.  If the primary policy instrument employed in the state and regional policies is cap-and-trade, then the respective carbon markets can be linked.  Such linkage occurs through bilateral recognition of allowances, which results in reduced costs, reduced price volatility, reduced leakage, and reduced market power.  Good news all around.

Such bottom‑up linkage of state and regional cap‑and‑trade systems could be an important part or perhaps even the core of future of U.S. climate policy, at least until there is meaningful action at the Federal level.  In the meantime, it is at least conceivable — and perhaps likely — that linkage of state‑level cap‑and‑trade systems will become the (interim) de facto national climate policy architecture.

In this way, Sacramento would take the place of Washington as the center of national climate policy deliberations and action.  No doubt, this possibility will please some, and frighten others.
