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 15th 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.

Defining Success for Climate Negotiations in Copenhagen

The fact that President Obama has decided to attend the United Nations climate change negotiations in Copenhagen at the end of the two-week meetings on December 18th, rather than during the previous week on his way to Oslo to receive the Nobel Peace Prize, is important, because it increases – in my mind – the likelihood of a significant outcome from the negotiations.  However, my reasoning – as I explained in a blog post for the Financial Times – is not what most people may think.  It is a matter of what is called “endogeneity” in economics, that is, there is causality in both directions.  That’s a bit cryptic, so let me explain.

[Before I proceed, I should explain that I have agreed to blog periodically from Copenhagen for the Financial Times, analyzing some of the issues before the negotiators in response to questions from the Financial Times‘ editors and reporters.  Those posts can be viewed at the Financial Times energy-source web site.]

Although it is true that President Obama’s presence on the concluding day of the negotiations (when – taking Kyoto in 1997 as an example – some of the key deals are finally struck) can have some influence, it is even more true that this decision by the White House signals that the Administration has reason to believe that there will be a visibly successful outcome of the Copenhagen talks.

His initial decision to visit the negotiations the previous week would have shielded the President – to a considerable degree — from any embarrassment and bad publicity if the negotiations were to fall apart.  (The President does not need to fly back from Copenhagen a second time having failed on his mission; his attempt to bring the Olympic games to Chicago is still fresh in the minds of the international press.)

Therefore, the fact that the White House has decided to send the President to Copenhagen for the final day, where he will assemble with some 90 other world leaders, and participate in closing statements (not to mention photo opportunities), indicates that the Administration is relatively confident that the talks will not collapse in a logjam of disagreement between the industrialized world and the developing countries, but rather that there will be a successful outcome.

The key outstanding question is whether the outcome will be one that provides a sound foundation for meaningful, long-term global action, not simply some notion of immediate, albeit highly visible triumph.  This is a subject on which I wrote in the Boston Globe (“A Silver Lining in the Climate Talks Cloud”) on Sunday, December 6, 2009, and it is my major focus here.

The gloom and doom predictions we’ve been hearing about the global climate negotiations taking place in Copenhagen this week and next are fundamentally misguided.  The picture is much brighter than it might seem for this international conference aimed at coming up with a successor for the Kyoto Protocol, which essentially sunsets in 2012.

The best goal for the Copenhagen 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) is and 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, long-term technological change is the key to the needed transition from reliance on carbon-intensive fossil fuels to more climate-friendly energy sources.

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

Indeed, it would be easy, but unfortunate, for countries to achieve what some people wish to define as “success” in Copenhagen:  a signed international agreement, glowing press releases, and related photo opportunities for national leaders.  Such an agreement could only be the Kyoto Protocol on steroids:  more stringent targets for the industrialized countries and no meaningful commitments by the key rapidly-growing emerging economies of China, India, Brazil, Korea, Mexico, and South Africa (let alone by the numerous developing countries of the world).

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.

If it’s not reasonable to expect that a comprehensive post-Kyoto policy architecture will be identified in Copenhagen, what would constitute real progress?  One important step forward would be a constructive joint-communiqué from major countries (just seventeen industrialized and emerging economies account for about 90% of annual emissions).

Such a joint-communiqué could lay out key progressive principles to underlie a future climate agreement, such as making the United Nations notion of  “common but differentiated responsibilities” meaningful through a 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.

In addition, a mid-term agreement could be reached on an approach involving an international portfolio of domestic commitments, whereby each nation would commit and register to abide by its domestic climate commitments, whether those are in the form of laws and regulations or multi-year development plans.  Support for such an approach has been voiced by a remarkably diverse set of countries, including Australia, India, and the United States.

The key question is not what this approach would accomplish in the short-term, but whether it would put the world in a better position two, five, and ten years from now in regard to a long-term path of action.

Consistent with this portfolio approach, President Obama recently announced that the United States would put a target on the table in Copenhagen to reduce emissions 17 percent below 2005 levels by 2020 (in line with climate legislation in the U.S. Congress).  In response, China announced that it would reduce its carbon intensity (emissions per unit of economic activity) 40 percent below 2005 levels over the same period of time.  Subsequently, India announced similar targets.  Given these countries rapid rates of economic growth, the announced targets won’t cut emissions in absolute terms, but they are promising starting points for negotiations.

So, despite the multitude of negative pronouncements about the slow pace of international climate negotiations, there are positive developments and promising paths forward. It is fortunate that a few key nations, including the United States, appear to be more interested in real progress than symbolic action.

Can Countries Cut Carbon Emissions Without Hurting Economic Growth?

In the September 21st issue of the Wall Street Journal, the editors pose the following question: can countries cut carbon emissions without hurting economic growth? In his introductory essay, Michael Totty frames the issues as follows:

“There’s little doubt: Cutting greenhouse gases will be costly. But that leads to two big questions. First, how costly? And second, can nations afford it? As policy makers around the world take action to avoid a predicted climate catastrophe, the debate is turning to the costs of reducing carbon-dioxide emissions. Energy-efficiency measures are often pricey, and alternative energy sources are more expensive than the fossil fuels they replace. A steep price on carbon emissions will ripple through the economy. Does that mean a serious effort to tackle global warming is incompatible with economic growth? Or can we make significant cuts in greenhouse-gas emissions without causing serious damage to the economy?

We put the question to a pair of experts. Robert Stavins, a professor of business and government at Harvard University and director of Harvard’s environmental economics program, says the answer to the second question is yes: Making the necessary cuts need cause little more than a blip in world-wide growth if smart policies are used.

Steven Hayward, a fellow at the American Enterprise Institute for Public Policy Research, says no: Energy use — and the carbon dioxide it emits — is so central to the world’s economy that major cuts can’t be made without significant damage.

Of course, the answers can depend in large part on how “significant cuts” and “serious damage” are defined. Many scientists, the European Parliament and the Waxman-Markey climate legislation approved by the U.S. House of Representatives have set a goal of cutting carbon emissions about 80% by 2050, so that was picked as constituting significant cuts.

As the accompanying essays show, such a definition leaves plenty of room for disagreement.”

I encourage you to read the entire Journal Report on Environment in the Wall Street Journal (there’s an excellent Q&A on carbon offsets by Bob Curran) and to check out my affirmative response, “Yes: The Transition Can be Gradual — and Affordable,” as well as Steven Hayward’s well-articulated negative response, “No: Alternatives are Simply Too Expensive.”

Understandably, the editors wanted to highlight differences between us in order to develop a concise and clear debate. I find it interesting, however, that in an audio interview/debate at the Wall Street Journal web site (Podcast: Crafting a Global Policy), which was by nature more free-wheeling and less limited by space constraints, there is a remarkable amount of agreement between Mr. Hayward and me on a number of key issues.

For now, in today’s post — liberated from space constraints — I want to expand a bit on my WSJ essay, in which I responded, yes, the transition can be gradual and affordable.

Can the nations of the world meaningfully address the threat of global climate change without inflicting unjustifiable damage to their economies? The answer that has emerged with increasing clarity is a resounding “yes.”

Although “The Day After Tomorrow,” the 2004 disaster epic about the greenhouse effect’s apocalyptic consequences, had less scientific basis than “The Wizard of Oz,” scientific reality is disturbing enough. Man-made emissions of greenhouse gases — including carbon dioxide (CO2) from the combustion of fossil fuels — are very likely to change the earth’s climate in ways that most people will regret. World energy trends are unsustainable — environmentally, economically, and socially.

The global recession has slowed emissions growth, but the world is on a path to more than double global atmospheric greenhouse gas (GHG) concentrations to 1,000 parts per million (ppm) in CO2-equivalent terms by the end of the century, resulting in an average global temperature increase of 6 degrees Centigrade. But increased temperatures — which might well be welcome in some places — are only part of the story.

The most important consequences of climate change will be changes in precipitation (causing, for example, 75 to 250 million people in Africa to be exposed to increased water stress due to climate change by 2020, with rain-fed agriculture yields falling by as much as 50%), disappearance of glaciers throughout the world (and decreased snowpack in areas ranging from the western United States to Asia), droughts in mid to low latitudes (with severe effects in Australia), decreased productivity of cereal crops (at lower latitudes, especially in tropical regions), increased sea level, loss of islands and 30% of global coastal wetlands, increased flooding (in all parts of the world, but greatest in Asia), greater storm frequency and intensity (both typhoons and hurricanes), risk of massive species extinction (20 to 30% of all species, including massive coral mortality), and significant spread of infectious disease. On the other hand, climate change will also bring some health benefits to temperate areas, such as fewer deaths from cold exposure. But such benefits will be greatly outweighed by negative health effects of rising temperatures (cardo-respiratory, diarrhoeal, and infectious diseases, and increased morbidity and mortality from heat waves, floods, and droughts), especially in developing countries.

These impacts will have severe economic, social, and political consequences for countries worldwide, ranging from malnutrition and mass migration (hundreds of millions of people displaced) to national security threats. Bottom-line, comprehensive estimates of economic impacts of unrestrained climate change vary, with most falling in the range of 2 to 5% of world GDP per year by the middle of the century. The best estimates of marginal damages of emissions (again, by mid-century) are in the range of $100 to $175 per ton of CO2 (in today’s dollars).

The world is already experiencing the adverse effects of increasing concentrations of GHGs in the atmosphere, with concentrations already about 60% above pre-industrial levels, greatly exceeding the natural range over the past 600,000 years. Just one example: the Greenland ice sheet has been losing mass at a rate of 179 billion tons per year since 2003.

To have a coin toss’s 50-50 chance of keeping temperature increases below 2 degrees Centigrade — the level at which the worst consequences of climate change can be avoided — it will be necessary to stabilize atmospheric concentrations at 450 ppm. (Even this would result in significant sea-level rise, species loss, and increased frequency of extreme weather, according to the U.N. Intergovernmental Panel on Climate Change.) Consistent with the 450 ppm goal is a long-range target of cutting U.S. emissions 80% below 2005 levels by 2050, which happens to be the target of legislation passed earlier this year by the U.S. House of Representatives, H.R. 2454, the so-called Waxman-Markey bill.

Now, to the heart of the WSJ question: will a serious effort to tackle global warming is incompatible with economic growth? My response was and is that the nations of the world do not have to wreck their economies to avert the crisis. If appropriate and intelligent policies are employed, the job can be done at reasonable and acceptable cost.

Critics argue that the Waxman-Markey legislation — to cut U.S. emissions 80% below 2005 levels by 2050 — will mean big, disruptive changes to our infrastructure and untold economic damage. But they make a couple of basic errors. For one thing, they seem to think we’d have to replace the entire infrastructure quickly, paying trillions of dollars to shift to cleaner power. They also seem to assume that we have to choose between much more expensive energy and no energy at all.

The move to greener power doesn’t have to be completed immediately, and it doesn’t have to be painful. The right transition plan will increase consumers’ bills gradually and modestly, and allow companies to make gradual, well-timed moves.

How would this work? One way is via a combination of national and multinational cap-and-trade systems. Companies around the world would be issued rights by their governments to produce carbon, which they could buy and sell on an open market. If they wanted to produce more carbon, they could buy another company’s rights. If they produced less carbon than they needed, they could sell their extra rights. What’s more, companies could earn more rights by creating appropriate “offsets” that mitigated their carbon use, such as planting forests. Nations could add carbon taxes to the mix.

The effect would be to send price signals through the market — making use of less carbon-intensive fuels more cost-competitive, providing incentives for energy efficiency and stimulating climate-friendly technological change, such as methods of capturing and storing carbon, as well as safe nuclear power.

More Efficient

True, in the short term changing the energy mix will come at some cost, but this will hardly stop economic growth. As economies have grown and matured, they have become more adept at squeezing more economic activity out of each unit of energy they generate and consume. Consider this: From 1990 to 2007, while world emissions rose 38%, world economic growth soared 75% — emissions per unit of economic activity fell by more than 20%.

Critics argue we can’t possibly increase efficiency enough to hit the 80% goal. In a very limited sense, that’s true. Efficiency improvements alone, like the ones that propelled us forward in the past, won’t get us where we need to go by 2050. But this plan doesn’t rely solely on boosting efficiency. It brings together a host of other changes, such as moving toward greener power sources. What’s more, making gradual changes means we don’t have to scrap still-productive power plants, but rather begin to move new investment in the right direction.

As for how much this will cost, the best economic analyses — including studies from the U.S. Congressional Budget Office and the U.S. Energy Information Administration — say such a policy in the U.S. could cost considerably less than 1% of gross domestic product per year in the long term, or up to $175 per household in 2020. (As the Obama administration is fond of saying, that’s about the cost of one postage stamp per household per day.)

In the end, we would be delaying 2050’s expected economic output by no more than a few months. And bear in mind that previous environmental actions, such as attacking smog-forming air pollution and cutting acid rain, have consistently turned out to be much cheaper than predicted.

The best economic experts have validated the wisdom of adopting climate policies: from Yale’s William Nordhaus, who has supported moderate carbon taxes to cut emissions as an “insurance policy” against the most serious consequences of climate change, to MIT’s Richard Schmalensee and Columbia’s Glenn Hubbard, who have endorsed the climate policy recommendations of the bipartisan National Commission on Energy Policy, to Harvard’s Martin Weitzman, who has argued for much more aggressive policies because of the risk of particularly catastrophic outcomes. And a diverse set of CEOs, including the heads of some of the largest U.S. corporations, acting as part of the U.S. Climate Action Partnership, have called on the government “to quickly enact strong national legislation to require significant reductions of greenhouse gas emissions.”

Critics are wary of raising energy prices, arguing that no nations have grown wealthy with expensive power. But historically, it is the scarcity and cost of energy that have prompted technological changes as well as the use of new forms of power. What’s more, critics challenge the price estimates the experts have set out. They say that the predictions depend on extensive — and unrealistic — cooperation among nations. In particular, they say, developing nations won’t sign onto plans for curbing emissions, for fear of losing their economic momentum.

Indeed, we do need a sensible international arrangement in place to achieve low costs, and the economic pain will be much greater if we don’t set up an international carbon market. But it can be done. Many nations have already initiated such emissions-control policies. And the world can be brought together in a meaningful, long-term arrangement that is scientifically sound, economically rational and politically pragmatic.

Road to Cooperation

Because the benefits of any single nation taking action to address global climate change are spread worldwide, unlike the costs, it may never be in the self-interest of a single country to take unilateral action. This is the nature of a global commons problem. For this reason, international cooperation is required; this is the point of climate negotiations among some 190 countries, which will continue in Copenhagen this December. It is also the motivation for the U.S. administration’s Major Economies Forum, which brings together the 17 largest economies, accounting for 80% of GHG emissions.

Europe has already put significant climate policy in place, and Australia, New Zealand, and Japan are moving to have their policies in place within a year. But without evidence of serious action by the U.S., there will be no meaningful future international agreement, and certainly not one that includes the key, rapidly-growing developing countries — Brazil, China, India, Indonesia, Mexico, South Africa, and South Korea. U.S. policy developments can and should move in parallel with international negotiations.

Understandably, developing countries have a very different perspective than the currently industrialized world regarding climate policy. After all, the vast majority of the accumulated stock of man-made greenhouse gases in the atmosphere is due to economic activity in the richer countries over the past century and more. But the share of global emissions attributable to developing countries is significant and growing rapidly. China surpassed the United States as the world’s largest CO2 emitter in 2006. And developing countries are likely to account for more than half of global emissions by the year 2020, if not before. China, Korea, and others are beginning to take action.

Most important, all of the key countries of the world can be brought together in a meaningful and pragmatic arrangement. Such a post-Kyoto international agreement can expand the scope of action to include key developing countries, but with targets linked via an appropriate formula with economic growth, so that emissions can be reduced around the world, while emissions (and job) leakage from the industrialized to the developing world is avoided, and economic growth continues in all parts of the world.

Reducing Costs

The longer we put off serious action, the more aggressive our future efforts will need to be, as greenhouse gases and carbon-spewing capital assets continue to accumulate. Plants built today will determine emissions for a generation. In the steel sector — where plant lifetimes typically exceed 25 years — more than half of all plants in the world are now less than 10 years old. The picture is similar in the cement industry, as well as more broadly throughout the economy. For every year of delay before moving to a sustainable emissions path, the global cost of taking necessary actions increases by hundreds of billions of dollars.

Critics argue that we can afford to wait because the world of tomorrow will be wealthier and better able to absorb the costs. But acting sooner, such as by adopting the emission caps proposed in the U.S. House legislation, will lower the ultimate costs of achieving the target, because there will be more time allowed for gradual transition — which is what keeps costs down. Perhaps most important, the costs of failing to take action — the damages of climate change — would be substantially greater.

Getting serious about climate change won’t be free, and it won’t be easy. But if state-of-the-science predictions about the consequences of continued delay are correct, the time has come for sensible and meaningful action.
