Defining Success for Climate Negotiations in Cancun

International climate negotiations will continue in Cancun, Mexico, during the first two weeks of December, 2010.  These will be the Sixteenth Conference of the Parties (COP-16) of the United Nations Framework Convention on Climate Change (UNFCCC).  The key challenge is to continue the process of constructing a sound foundation for meaningful, long-term global action, not necessarily some notion of immediate, highly-visible triumph.  Some of the gloom-and-doom predictions we’ve been hearing about these upcoming negotiations are therefore misguided, because they are based upon unreasonable – and fundamentally inappropriate – expectations (despite the fact that expectations have been lowered dramatically since COP-15 in Copenhagen last year).

Keeping Our Eyes on the Prize

Why do I say that the best goal for the Cancun climate talks is to make real progress on a sound foundation for meaningful, long-term global action, not some notion of immediate triumph?  This is because of some basic scientific and economic realities.

First, the focus of scientists (and policy makers) should be on stabilizing concentrations at acceptable levels by 2050 and beyond, because it is the accumulated stock of greenhouse gas emissions — not the flow of emissions in any year — that are linked with climate consequences.

Second, the cost-effective path for stabilizing concentrations involves a gradual ramp-up in target severity, to avoid rendering large parts of the capital stock prematurely obsolete.

Third, massive technological change is the key to the needed transition from reliance on carbon-intensive fossil fuels to more climate-friendly energy sources.  Long-term price signals (most likely from government policies) will be needed to inspire such technological change.

Fourth and finally, the creation of long-lasting international institutions is central to addressing this global challenge.

For all of these reasons, international climate negotiations will be an ongoing process, not a single task with a clear end-point.  Indeed, they may well proceed much as international trade talks have done, that is, with progress over many years, building the institutions (the GATT, the WTO), but moving forward in fits and starts, at times seeming to move backward, but making meaningful progress in the long term.

So, the bottom-line is that a sensible goal for the international negotiations in Cancun is progress on a sound foundation for meaningful long-term action, not some notion of immediate “success.”

Don’t Sacrifice Valuable Long-Term Achievements for Minor Short-Term Gains

It might be relatively easy, but actually quite unfortunate, for countries to achieve what some people might define as “success” in Cancun:  a signed international agreement, followed by glowing press releases.  I say it would be unfortunate, because such an agreement could only be the Kyoto Protocol on steroids: more stringent targets for the original list of industrialized countries (Annex I) and no meaningful commitments by the key rapidly-growing emerging economies, such as China, India, Brazil, Korea, Mexico, and South Africa.

Such an agreement could — in principle — be signed, but it would not reduce global emissions, and it would not be ratified by the U.S. Senate (just like Kyoto).  Hence, there would be no real progress on climate change.

What Would Constitute Real Progress in Cancun?

If it’s not reasonable to expect that a comprehensive post-Kyoto policy architecture will be identified and enacted in Cancun, what would constitute real progress?

1.  Embracing Parallel Processes

A significant step forward would be for the UNFCCC to embrace the parallel processes that are carrying out multilateral discussions (and in some cases, negotiations) on climate change policy:  the Major Economies Forum or MEF (a multilateral venue for discussions – but not negotiations – outside of the UNFCCC, initiated under a different name by the George W. Bush administration in the United States, and continued under a new name by the Obama administration, for the purpose of bringing together the most important emitting countries for candid and constructive discussion and debate); the G20 (periodic meetings of the finance ministers – and sometimes heads of government – of the twenty largest economies in the world); and various other multilateral and bilateral organizations and discussions.

By the way, the MEF includes Australia, Brazil, Canada, China, the European Union, France, Germany, India, Indonesia, Italy, Japan, Korea, Mexico, Russia, South Africa, the United Kingdom, and the United States. The membership of the G20 is the same as the membership of the MEF, plus Argentina, Saudi Arabia, and Turkey.

The previous leadership of the UNFCCC seemed to view the MEF, the G20, and most other non-UNFCCC forums as competition – indeed, as a threat.  Fortunately, the UNFCCC’s new leadership under Executive Secretary Christiana Figueres (appointed by UN Secretary-General Ban Ki-moon in May of this year) has displayed a considerably more positive and pragmatic attitude toward these parallel processes.

2.  Consolidating Negotiations Tracks

There are now three major, parallel processes operative:  first, the UNFCCC’s KP track (negotiating national targets for a possible second commitment period – post-2012 – for the Kyoto Protocol); second, the LCA track (the UNFCCC’s negotiation track for Long-term Cooperative Action, that is, a future international agreement of undefined nature); and third, the Copenhagen Accord, negotiated and noted at COP-15 in Copenhagen, Denmark, in December, 2009.  Consolidating these three tracks into two tracks (or better yet, one track) would be another significant step forward.

One way this could happen would be for the LCA negotiations to take as their point of departure the existing Copenhagen Accord, which itself marked an important step forward by blurring for the first time (although not eliminating) the unproductive and utterly obsolete distinction in the Kyoto Protocol between Annex I and non-Annex I countries.  (Note that more than 50 non-Annex I countries now have greater per capita income than the poorest of the Annex I countries.)

In particular, the UNFCCC principle of  “common but differentiated responsibilities” could be made meaningful through the dual principles that:  all countries recognize their historic emissions (read, the industrialized world); and all countries are responsible for their future emissions (think of those rapidly-growing emerging economies).

This would represent a great leap beyond what has become the “QWERTY keyboard” (that is, unproductive path dependence) of international climate policy:  the distinction in the Kyoto Protocol between the small set of Annex I countries with quantitative targets, and the majority of countries in the world with no responsibilities.  Various policy architectures could subsequently build on these dual principles and make them operational, beginning to bridge the massive political divide which exists between the industrialized and the developing world.

At the Harvard Project on Climate Agreements — a multi-national initiative with some 35 research projects in Australia, China, Europe, India, Japan, and the United States — we have developed a variety of architectural proposals that could make these dual principles operational.  (See, for example:  “Global Climate Policy Architecture and Political Feasibility: Specific Formulas and Emission Targets to Attain 460 PPM CO2 Concentrations” by Valentina Bosetti and Jeffrey Frankel; and “Three Key Elements of Post-2012 International Climate Policy Architecture” by Sheila M. Olmstead and Robert N. Stavins.)

3.  Productive Steps in Narrow, Focused Agreements, such as REDD+

A third area of success at the Cancun negotiations could be realized by some productive steps with specific, narrow agreements, such as on REDD+ (Reduced Deforestation and Forest Degradation, plus enhancement of forest carbon stocks).  Other areas where talks are moving forward, although somewhat more slowly, are finance and technology.

4.  Maintaining Sensible Expectations and Developing Effective Plans

Finally, it is important to go into the Cancun meetings with sensible expectations and thereby effective plans.  Again, negotiations in this domain are an ongoing process, not a single task with a clear end-point.  The most sensible goal for Cancun is progress on a sound foundation for meaningful long-term action, not some notion of immediate triumph.  The key question is not what Cancun accomplishes in the short-term, but whether it helps put the world in a better position five, ten, and twenty years from now in regard to an effective long-term path of action to address the threat of global climate change.

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.

Opportunities and Ironies: Climate Policy in Tokyo, Seoul, Brussels, and Washington

As I write this, I’m on board a flight from Seoul, South Korea, to San Francisco, California, on my way home to Boston, having spent the week of Harvard spring break meeting with senior government officials, academics, and leaders of civil society in Tokyo and Seoul on behalf of the Harvard Project on International Climate Agreements.  Reflecting on these meetings in Asia and recalling meetings I’ve previously had in Brussels and Washington, some important opportunities and ironies about national and international climate policy come to mind.

Opportunities

The 15th Conference of the Parties (COP-15) of the United Nations Framework Convention on Climate Change (UNFCCC), which met in Copenhagen, Denmark, in December, 2009, produced two significant outcomes.  The key substantive outcome, of course, was the Copenhagen Accord, about which I’ve written in detail in a previous blog post.  The key institutional outcome was speculation that the UNFCCC may not be the best venue going forward for productive negotiations on climate change.   (This is also a topic about which I’ve recently written at this blog.)

These dual outcomes of the Copenhagen conference point to the special importance of two key nations in international climate policy developments this year.  I’m not referring to China and the United States (despite the fact that they are, of course, the world’s two leading emitters of carbon dioxide).  Rather, I am referring to Korea and Mexico.  Why?

First, these two nations are unique in being both long-time members (Korea since 1996, Mexico since 1994) of the Organization of Economic Cooperation and Development (OECD) and members of the group of non-Annex I countries under the Kyoto Protocol, which have no direct commitments under that international agreement.  The OECD comes as close as anything to defining the set of industrialized nations of the developed world.  Thus, Korea and Mexico have their feet planted firmly both in the developed world and the developing world (a fact that is readily apparent on even brief visits to these nations).  This gives Korea and Mexico remarkable credibility with the two key blocks in international climate negotiations.  That, on its own, would be of considerable importance, but there is another reality that makes this of even greater significance (and opportunity) in this year of 2010.

Coming out of Copenhagen, many participants in the international climate negotiations (as well as informed observers), noted that the UNFCCC has real limitations as the sole venue for future climate negotiations:  too many countries – 192, excessively stringent requirements for agreement – unanimity, and a distinct tendency to polarize debates between developed and developing countries.  Two other, potentially supplementary venues stand out as promising:  the Major Economies Forum (MEF) and the G20.

The MEF, which has hosted productive discussions among 17 key countries and regions that together account for nearly 90 percent of global carbon dioxide (CO2) emissions, may be somewhat limited by the fact that is was created by and is chaired by the United States, a nation with constrained credibility on climate issues among some countries, particularly in the developing world.  The G20, which brings together twenty of the world’s largest economies, focuses on economic as well as other global issues and consists of almost the same set of nations as the MEF, likewise accounting for about 90 percent of global emissions.  The G20 could thus be an exceptionally promising supplementary venue for meaningful and realistic climate discussions.  And in November of this year, the G20 will be hosted by Korea, when it convenes in Seoul.  This gives the Korean government a special role in setting the agenda for the discussions and presiding at the sessions.

The G20 meetings in Seoul will come just two weeks before the Sixteenth Conference of the Parties of the UNFCCC, which will take place in Cancún, Mexico.  Thus, the Mexican government is also in a key position this year, because it will hold the Presidency of COP-16.

Add to this the fact that both Korea and Mexico have been particularly creative in their domestic climate policy initiatives and international proposals over the past year.   Harvard Kennedy School Professor Jeffrey Frankel notes at his blog — Views on the Economy and the World — that Korea and Mexico were particularly ambitious with their submissions to the Copenhagen Accord, when comparing the submissions of all countries in terms of 2020 emissions targets relative to business-as-usual, controlling for per capita income.

Together, Korea and Mexico, share credibility in the developing and developed worlds, and likewise share unique international legitimacy as the hosts and presidents of the G20 and COP-16 in 2010.  This is why these two countries have a remarkable opportunity this year to provide leadership of the international community, and make real progress on negotiations to address the threat of global climate change.  Those are the opportunities.   Now, let me turn to the ironies that have come to the fore.

Ironies

More than a decade ago, it was the United States, as the leader of the so-called “Umbrella Group,” that successfully fought for the inclusion in the Kyoto Protocol – over the objections of the European Union – of three “flexibility mechanisms” to bring down the costs of meeting the Protocol’s objectives:  joint implementation (Article 4), a global emissions reduction credit system, the Clean Development Mechanism (the CDM, Article 12), and emissions trading among countries (Article 17).  Ironically, once the George W. Bush administration officially pulled the United States out of the Kyoto Protocol process, it was the European Union that implemented the world’s first CO2 emissions trading program, the European Union Emission Trading Scheme (EU ETS).

Beyond this, the United States was a pioneer with the use of national cap-and-trade systems, including lead trading in the 1980s and the SO2 allowance trading program beginning in 1995 under the Clean Air Act Amendments of 1990.  In addition, despite its lack of ratification of the Kyoto Protocol, the U.S. government very early on began to give serious consideration to the development of an economy-wide cap-and-trade system for CO2 with the McCain-Lieberman legislation in the U.S. Senate (followed later by the Lieberman-Warner bill).  More recently, of course, the U.S. House of Representatives passed the Waxman-Markey bill in June of 2009, including a significant economy-wide cap-and-trade system.

Over the past nine months, however, the very phrase, “cap-and-trade,” has evolved from being politically correct in Washington to nothing less than politically anathema.  (How and why this happened is a topic for a future essay at this blog.)  The great irony is that just when cap-and-trade has been under such vociferous attack in Washington, countries throughout the world are embracing this instrument, recognizing its great potential to address climate change cost-effectively and equitably.

In addition to the EU ETS, already in force, Australia is primed to put its cap-and-trade system in place, as is New Zealand.  And just a few days before I arrived in Tokyo, the Japanese cabinet announced that the government will move forward with a cap-and-trade system (in contrast with Japan’s previously proposed sectoral approach).  And, not to be outdone, Korea is considering the use of cap-and-trade as an element of its own domestic climate policy.

This irony is striking.  Of course, it could be reduced or eliminated if Senators Kerry, Graham, and Lieberman can use their much-anticipated new climate proposal to pull victory from the jaws of anticipated defeat.   Only time will tell.
