Here We Go Again: A Closer Look at the Kerry-Lieberman Cap-and-Trade Proposal

As with the Waxman-Markey bill (H.R. 2454), passed by the House of Representatives last June, there is now some confusing commentary in the press and blogosphere about the allocation of allowances in the new Senate proposal — the American Power Act of 2010 — sponsored by Senator John Kerry, Democrat of Massachusetts, and Senator Joseph Lieberman, Independent of Connecticut. As before, the mistake is being made of confusing the share of allowances that are freely allocated versus auctioned with (the appropriate analysis of) the actual incidence of the allowance value, that is, who ultimately benefits from the allocation and auction revenue.

In this essay, I assess quantitatively the actual incidence of the allowance value in the new Senate proposal, much as I did last year with the House legislation. I find (as with Waxman-Markey) that the lion’s share of the allowance value — some 82% — goes to consumers and public purposes, and only 18% accrues to covered, private industry. First, however, I place this in context by commenting briefly on the overall Senate proposal, and by examining in generic terms the effects that allowance allocations have — and do not have — in cap-and-trade systems.

The American Power Act of 2010

You may be wondering why I am bothering to write about the Kerry-Lieberman proposal at all, given the conventional wisdom that the likelihood is very small of achieving the 60 votes necessary in the Senate to pass the legislation (particularly with the withdrawal of Senator Lindsay Graham — Republican of South Carolina — from the former triplet of Senate sponsors). Two reasons. First, conventional wisdoms often turn out to be wrong (although I must say that the vote count on Kerry-Lieberman does not look good, with the current tally according to Environment & Energy Daily being 26 Yes, 11 Probably Yes, 31 Fence Sitters, 10 Probably No, and 22 No). Second, if the conventional wisdom turns out to be correct, and the 60-vote margin proves insurmountable in the current Congress, then when the Congress returns to this issue — which it inevitably will in the future — among the key starting points for Congressional thinking will be the Waxman-Markey and Kerry-Lieberman proposals. Hence, the design issues do matter.

The American Power Act, like its House counter-part, is a long and complex piece of legislation with many design elements in its cap-and-trade system (which, of course, is not called “cap-and-trade” — but rather “reduction and investment”), and many elements that go well beyond the cap-and-trade system (sorry, I meant to say the “reduce-and-invest” system). Perhaps in a future essay, I will examine some of those other elements (wherein there is naturally both good news and bad news), but for today, I am focusing exclusively on the allowance allocation issue, which is of central political importance.

Before turning to an empirical examination of the Kerry-Lieberman allowance allocation, it may be helpful to recall some generic facts about the role that allowance allocations play in cap-and-trade systems.

The Role of Allowance Allocations in Cap-and-Trade Systems

It is exceptionally important to keep in mind what is probably the key attribute of cap-and-trade systems: the particular allocation of those allowances which are freely distributed has no impact on the equilibrium distribution of allowances (after trading), and therefore no impact on the allocation of emissions (or emissions abatement), the total magnitude of emissions, or the aggregate social costs. (There are some caveats, about which more below.) By the way, 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.

Generally speaking, the choice between auctioning and freely allocating allowances does not influence firms’ production and emission reduction decisions (although it’s true that the revenue from auctioned allowances can be used for a variety of public purposes, including cutting distortionary taxes, which can thereby reduce the net cost of the program). Firms face the same emissions cost regardless of the allocation method. When using an allowance, whether it was received for free or purchased, a firm loses the opportunity to sell that allowance, and thereby recognizes this “opportunity cost” in deciding whether to use the allowance. Consequently, the allocation choice will not — for the most part — influence a cap’s overall costs.

Manifest political pressures lead to different initial allocations of allowances, which affect distribution, but not environmental effectiveness, and not cost-effectiveness. This means that ordinary political pressures need not get in the way of developing and implementing a scientifically sound, economically rational, and politically pragmatic policy. With other policy instruments — both in the environmental realm and in other policy domains — political pressures often reduce the effectiveness and/or increase the cost of well-intentioned public policies. Cap-and-trade provides natural protection from this. Distributional battles over the allowance allocation in a cap-and-trade system do not raise the overall cost of the program nor affect its environmental impacts.

In fact, the political process of states, districts, sectors, firms, and interest groups fighting for their share of the pie (free allowance allocations) serves as the mechanism whereby a political constituency in support of the system is developed, but without detrimental effects to the system’s environmental or economic performance. That’s the good news, and it should never be forgotten.

But, depending upon the specific allocation mechanisms employed, there are several ways that the choice to freely distribute allowances can affect a system’s cost. Here’s where the caveats come in.

Some Important Caveats

First, as I said above, auction revenue may be used in ways that reduce the costs of the existing tax system or fund other socially beneficial policies. Free allocations forego such opportunities.

Second, some proposals to freely allocate allowances to electric utilities may affect electricity prices, and thereby affect the extent to which reduced electricity demand contributes to limiting emissions cost-effectively. Waxman-Markey and Kerry-Lieberman both allocate a significant number of allowances to local (electricity) distribution companies, which are subject to cost-of-service regulation even in regions with restructured wholesale electricity markets. Because the distribution companies are subject to cost-of-service regulation, the benefit of the allocation will ultimately accrue to electricity consumers, not the companies themselves. While these allocations could increase the overall cost of the program if the economic value of the allowances is passed on to consumers in the form of reduced electricity prices, if that value is instead passed on to consumers through lump-sum rebates, the effect can be to compensate consumers for increased electricity prices without reducing incentives for energy conservation. (There are some legitimate behavioral questions here about how consumers will respond to such rebates; these questions are best left to ongoing economic research.)

Third, “output-based updating allocations” can be useful for addressing competitiveness impacts of a climate policy on particularly energy-intensive and trade-sensitive sectors, but these allocations can provide perverse incentives and drive up the costs of achieving a cap if they are poorly designed. This merits some explanation.

An output-based updating allocation ties the quantity of allowances that a firm receives to its output (production). Such an allocation is essentially a production subsidy. While this affects firms’ pricing and production decisions in ways that can, in some cases, introduce unintended consequences and increase the cost of meeting an emissions target, when applied to energy-intensive trade-exposed industries, the incentives created by such allocations can contribute to the goal of reducing emission leakage abroad.

This approach is probably superior to an import allowance requirement, whereby imports of a small set of specific commodities must carry with them CO₂ allowances, because import allowance requirements can damage international trade relations. The only real solution to the competitiveness issue is to bring key non-participating countries within an international climate regime in meaningful ways, an obviously difficult objective to achieve. (On this, please see the work of the Harvard Project on International Climate Agreements.)

Is the Kerry-Lieberman Allowance Allocation a Corporate Give-Away?

Perhaps unintentionally, there has been some potentially misleading coverage on this issue. At first glance, about half of the allowances would be auctioned and about half freely allocated over the life of the program, 2012-2050. (In the early years, the auction share is smaller, reflecting various transitional allocations that phase out over time.) But looking at the shares that are auctioned and freely allocated can be very misleading.

Instead, the best way to assess the real implications is not as “free allocation” versus “auction,” but rather in terms of who is the ultimate beneficiary of each element of the allocation and auction, that is, how the value of the allowances and auction revenue are allocated. On closer inspection, it turns out that many of the elements of the apparently free allocation accrue to consumers and public purposes, not private industry. Indeed, my conclusion is that over the period 2012-2050, less than 18% of the allowance value accrues to industry.

First, let’s looks at the elements which will accrue to consumers and public purposes. Next to each allocation element is the respective share of allowances over the period 2012-2050:

I. Cost Containment

a. Auction from cost containment reserve, 3.1%

II. Indirect Assistance to Mitigate Impacts on Energy Consumers

b. Electricity local distribution companies, 18.6%

c. Natural gas local distribution companies, 4.1%

d. State programs for home heating oil, propane, and kerosene consumers, 0.9%

III. Direct Assistance to Households and Taxpayers

e. Allowances auctioned to provide tax and energy refunds for low-income households, 11.7%

f. Allowances auctioned for universal tax refunds, 22.3%

IV. Other Domestic Priorities

g. State renewable and energy efficiency programs, 0.6%

h. State and local agency programs to reduce emissions through transportation projects, 1.9%

i. Grants for national surface transportation system, 1.9%

j. Auctioned allowances for Highway Trust Fund, 1.9%

k. Domestic adaptation, 1.0%

l. Rural energy savings (consumer loans to implement energy efficiency measures), 0.1%

V. International Funding

m. International adaptation, 1.0%

VI. Deficit Reduction

n. Allowances auctioned for deficit reduction, 7.4%

o. Remaining allowances auctioned to offset bill’s impact on deficit, 6.1%

Next, the following elements will accrue to private industry, again with average (2012-2050) shares of allowances:

I. Allocations to Covered Entities

a. Energy-intensive, trade-exposed industries, 7.0%

b. Petroleum refiners, 2.2%

c. Merchant coal-fired electricity generators, 2.2%

d. Generators under long-term contracts without cost recovery, 0.9%

II. Technology Funding

e. Carbon capture and sequestration incentives, 3.8%

f. Clean energy technology R&D, 0.7%

g. Low-carbon manufacturing R&D, 0.3%

h. Clean vehicle technology incentives, 0.3%

III. Other Domestic Priorities

i. Manufacturing plant energy efficiency retrofits, 0.1%

j. Compensation for early action emissions reductions prior to cap’s implementation, 0.1%

The bottom line? Over the entire period from 2012 to 2050, 82.6% of the allowance value goes to consumers and public purposes, and 17.6% to private industry. Rounding error brings the total to 100.2%, so to be conservative, I’ll call this an 82%/18% split.

Moreover, because some of the allocations to private industry are – for better or for worse – conditional on recipients undertaking specific costly investments, such as investments in carbon capture and storage, part of the 18% free allocation to private industry should not be viewed as a windfall.

I should also note that some observers (who are skeptical about government programs) may reasonably question some of the dedicated public purposes of the allowance distribution, but such questioning is equivalent to questioning dedicated uses of auction revenues. The fundamental reality remains: the appropriate characterization of the Kerry-Lieberman allocation is that about 82% of the value of allowances go to consumers and public purposes, and 18% to private industry.

Comparing the Kerry-Lieberman 82/18 Split with Recommendations from Economic Analyses

The 82-18 split is roughly consistent with empirical economic analyses of the share that would be required – on average — to fully compensate (but no more) private industry for equity losses due to the policy’s implementation. In a series of analyses that considered the share of allowances that would be required in perpetuity for full compensation, Bovenberg and Goulder (2003) found that 13 percent would be sufficient for compensation of the fossil fuel extraction sectors, and Smith, Ross, and Montgomery (2002) found that 21 percent would be needed to compensate primary energy producers and electricity generators.

In my work for the Hamilton Project in 2007, I recommended beginning with a 50-50 auction-free-allocation split, moving to 100% auction over 25 years, because that time-path of numerical division between the share of allowances that is freely allocated to regulated firms and the share that is auctioned is equivalent (in terms of present discounted value) to perpetual allocations of 15 percent, 19 percent, and 22 percent, at real interest rates of 3, 4, and 5 percent, respectively. My recommended allocation was designed to be consistent with the principal of targeting free allocations to burdened sectors in proportion to their relative burdens, while being politically pragmatic with more generous allocations in the early years of the program.

So, the Kerry-Lieberman 82/18 allowance split (like the 80/20 Waxman-Markey allowance split) turns out to be consistent — on average, i.e. economy-wide — with independent economic analysis of the share that would be required to fully compensate (but no more) the private sector for equity losses due to the imposition of the cap, and consistent with my Hamilton Project recommendation of a 50/50 split phased out to 100% auction over 25 years.

The Path Ahead

Going forward, many observers and participants in the policy process may continue to question the wisdom of some elements of the Kerry-Lieberman proposal, including its allowance allocation. There’s nothing wrong with that.

But let’s be clear that, first, for the most part, the specific allocation of free allowances affects neither the environmental performance of the cap-and-trade system nor its aggregate social cost.

Second, we should recognize that the legislation is by no means a corporate give-away. On the contrary, 82% of the value of allowances accrue to consumers and public purposes, and some 18% accrue to covered, private industry. This split is roughly consistent with the recommendations of independent economic research.

Finally, it should not be forgotten that the much-lamented deal-making for shares of the allowances for various purposes that took place in the deliberations leading up the announcement by Senators Kerry and Lieberman was a good example of the useful, important, and fundamentally benign mechanism through which a cap-and-trade system provides the means for a political constituency of support and action to be assembled, without reducing the policy’s effectiveness or driving up its cost.

Chaos and Uncertainty in Copenhagen?

Earlier today, I was asked by the Financial Times, “who is responsible for the chaos and uncertainty” at COP-15 in Copenhagen? I’m not sure those are the words I would have chosen to characterize the situation at the climate negotiations in the Danish capital, but here is my response for the FT’s Energy-Source Climate Experts panel — with some elaboration.

There are two aspects to what has been characterized as the “chaotic and uncertain” nature of the COP-15 conference at the Bella Center in Copenhagen. One is the substantive process and eventual outcome, which remains uncertain as of this hour, and the other is the shocking logistical failure.

An Uncertain Outcome for the Negotiations

It should not be surprising that the outcome remains in doubt, because of some basic economic realities. First of all, keep in mind that climate change is the ultimate global commons problem, because greenhouse gases uniformly mix in the atmosphere. Therefore, each country incurs the costs of its emission-reduction actions, but the benefits of its actions are spread worldwide. Hence, for any individual nation, the benefits it receives from its actions are inevitably less than the costs it incurs, despite the fact that globally the total benefits of appropriate coordinated international action would exceed the total costs (and for many countries the national benefits of coordinated international action would exceed their national costs of action).

This creates a classic free-rider problem, and is the reason why international cooperation – whether through an agreement under the United Nations Framework Convention on Climate Change or through some other multilateral or bilateral arrangements – is necessary.

Second, addressing global climate change will be costly and it raises profound distributional implications for the countries of the world. In particular, addressing climate change at minimum cost (i.e., cost-effectively) requires that all countries take responsibility for their emissions going forward, and indeed necessitates that all countries control at the same marginal abatement cost.

On the other hand, addressing climate change in an equitable fashion clearly requires taking account of the dramatically different economic circumstances of the countries of the world, and may also involve looking backwards at historic responsibility for the anthropogenic greenhouse gases which have already accumulated in the atmosphere. These are profound issues of distributional equity.

This classic trade-off between cost-effectiveness (or efficiency), on the one hand, and distributional equity, on the other hand, raises significant obstacles to reaching an agreement.

So, I place the fault for the substantive uncertainty in the negotiations neither on the industrialized countries (including the United States, for insisting that China and other key emerging economies participate in meaningful and transparent ways), nor on the developing countries (for insisting that the industrialized world pay much of the bill).

The key question going forward is whether negotiators in Copenhagen today and tonight, or in Bonn several months from now, or in Mexico City a year from now, can identify a policy architecture that is both reasonably cost-effective and sufficiently equitable, and thereby can assemble support from the key countries of the world, and thus do something truly meaningful about the long-term path of global greenhouse gas emissions. There are promising paths forward, and – if you’ll forgive me – I will remind readers that many have been identified by the Harvard Project on International Climate Agreements.

Rather than pointing fingers at who is to blame for the current uncertainty at this hour, I can attribute credit to a number of countries and institutions for having brought the negotiations to the point where it appears at least possible that a successful outcome will be achieved in Copenhagen or subsequently.

First of all, tremendous credit must be given to the national leaders and the negotiating teams of the seventeen major economies of the world who together represent about 90% of global emissions, because these countries have worked hard to produce what each considers a sensible outcome over the months and years leading up to COP-15.

This includes not only the European Union, Australia, Japan, New Zealand, and Canada, but also the United States, which at least since January of this year has been an enthusiastic and intelligent participant in this international process. It also includes many of the key emerging economies of the world – China , India, Brazil, Mexico, Korea, South Africa, and Indonesia, among them – as well as a considerable number of poor, developing countries, which likewise take the problem seriously and have been trying to find an acceptable path forward.

Finally, credit should be given to the Danish government and its leadership, the Secretariat of the United Nations Framework Convention on Climate Change, and UN Secretary-General Ban Ki-moon, who have worked tirelessly for months, indeed years, to prepare for the substance of these negotiations at COP-15 in Copenhagen.

That’s the “good news,” but now I should turn to the other aspect of the “uncertainty and chaos” in Copenhagen.

Chaos at COP-15’s Bella Center

As I noted at the outset, there are two aspects of the “chaos” in Copenhagen, and for the second aspect it is (sadly) possible to identify the apparently responsible parties. I am referring to the fact that the organizers – the Secretariat of the United Nations Framework Convention on Climate Change (UNFCCC) and the hosts, the Danish government – apparently approved a list of some 40,000 observers from 900 official, accredited organizations around the world, knowing that the Bella Center could accommodate at most 15,000 persons at any one time. The result is that thousands of people – including not only NGO representatives, but also government negotiators – stood in line outside of the Bella Center in the bitter cold on Monday and Tuesday of this week waiting 8-10 hours to get inside to receive their credentials. Thousands of others never got inside to receive their credentials, despite having waited up to 8 hours, standing in the cold. These are not exaggerations. It is remarkable and very fortunate if no one died in the process.

Then, on Wednesday through Friday, the Bella Center was essentially closed to all representatives of civil society, despite the fact that side-events had been organized by them months in advance with the approval of the COP-15 organizers.

The result is that thousands of people, who had been informed by the COP-15 organizers many months ago that they were approved to attend, had flown to Copenhagen from all over the world, incurred those costs plus the costs of their accommodations, yet never were able to get inside the Bella Center to carry out any of the work they had planned, and flew back home having wasted their time and resources (and having contributed to the COP-15 carbon footprint in non-trivial ways).

Now, I have never been an enthusiast of what some people have described as the annual “circus” of the COPs, a circus – if it is that — which is largely due to the fact that the actual government negotiators are vastly outnumbered by the civil society representatives (“official observers” in the UNFCCC language) and the press. However, if the participation of civil society representatives is going to be encouraged (as required under the original UNFCCC agreement), and if the attendance of those representatives is going to be approved in advance, then surely they should not be denied admission when they arrive, nor forced to stand in line outside in the cold for 8 hours waiting to be admitted.

No doubt, both the UNFCCC and the Danish government will point fingers at the other, but ultimately the responsibility must be shared. In seventeen years of these annual conferences, going back to the 1992 Earth Summit in Rio de Janeiro, there has never been such a disastrous logistical failure. It could have been anticipated. And it should have been prevented.

A Final Word

Of course, as of this hour, I — along with millions of others — hope that the negotiators in Copenhagen will achieve agreement on some truly meaningful steps forward in this important process.

Only Private Sector Can Meet Finance Demands of Developing Countries

Things are getting hot here in Copenhagen. It’s not the weather outside, but the debate taking place inside the Bella Center, home of the 15^th Conference of the Parties of the UN Framework Convention on Climate Change. This afternoon, the main session of the talks was suspended, following protests led by African countries, which accused the industrialized countries of trying to wreck the existing Kyoto Protocol. At the heart of the controversy is the “finance question,” as it’s called here, with the developing countries asking for more than $100 billion to $200 billion annually to pay for their carbon mitigation and climate change adaptation through 2050!

At the National Journal’s “Copenhagen Insider” Blog, Congressman Ed Markey poses the highly relevant question of how much should wealthy countries help poor countries address climate change. In response to Congressman Markey’s question, I maintain that it is inconceivable that the governments of the industrialized world, including the United States, will come up with sufficient foreign aid to satisfy the demands for financial transfers being made by the developing countries in Copenhagen. However, governments can — through the right domestic and international policy arrangements — provide key incentives for the private sector to provide the needed finance through foreign direct investments.

For example, if the cap-and-trade systems which are emerging throughout the industrialized world as the favored domestic approach to reducing CO2 and other greenhouse gas emissions are linked together through the existing, common emission-reduction-credit system, namely the Clean Development Mechanism (CDM), then powerful incentives can be created for carbon-friendly private investment in the developing world.

Clearly the CDM, as it currently stands, cannot live up to this promise, but with appropriate reforms there is significant potential. Of course, problems of limited additionality will inevitably remain. Therefore, what is needed is for the key emerging economies — China, India, Brazil, Korea, South Korea, South Africa, and Mexico — to take on meaningful emission targets themselves (even if equivalent to business as usual in the short term), and then participate directly in international cap-and-trade, not government-government trading as envisioned in Article 17 of the Kyoto Protocol (which won’t work), but firm-firm trading through linked national and multi-national cap-and-trade systems.

Such private finance stands a much greater chance than government aid of being efficiently employed, that is, targeted to reducing emissions, rather than spent by poor nations on other (possibly meritorious) purposes. So, all in all, the job can be done, and governments have an important role, but as facilitators, not providers, of finance. This should be the focus of the discussion here in Copenhagen.
