Michael Wara shows while inducing significant participation by developing countries, the Clean Development Mechanism has failed to realize its full environmental potential. Reductions are much smaller than claimed, politicization is prominent, and the scheme has done little to encourage the profound changes in energy technology needed to address climate change.

Stanford, California - If the deal to supply India with nuclear technologies goes through, future generations may remember it for quite different reasons than the debate over nuclear proliferation.

Nuclear power emits no carbon dioxide, the leading cause of global warming. And India, like most developing countries, has not been anxious to spend money to control its emissions of this and other so- called greenhouse gases.

India is embracing nuclear power for other reasons - because it can help the country solve its chronic failure to supply the electricity needed for a burgeoning economy. But in effect, the deal would marry their interest in power with ours in protecting the planet.

India is growing rapidly. In recent years its economy has swelled at more than 7 percent per year, and many analysts believe it is poised to grow even faster in the coming decade.

The economic growth is feeding a voracious appetite for electricity that India's bankrupt utilities are unable to satisfy. Blackouts are commonplace. Farmers, who account for about two-fifths of all the power consumed, can barely rely on getting power for half of every day. In industrial zones, the lifeblood of India's vibrant economy, unstable power supplies are such trouble that the biggest companies usually build their own power plants.

So most analysts expect that the demand for electricity will rise at about 10 percent a year. (For comparison, U.S. power demand notches up at just 2 percent annually.)

Over the past decade, about one third of India's new power supplies came from natural gas and hydro electricity. Both those sources have been good news for global warming - natural gas is the least carbon- intensive of all the fossil fuels, and most of India's hydroelectric dams probably emit almost no greenhouse gases.

However, the bloom is coming off those greenhouse-friendly roses. New supplies of natural gas cost about twice what Indians are used to paying, and environmental objections are likely to scupper the government's grand plans for new hydro dams.

That leaves coal - the most carbon-intensive of all fossil fuels. Already more than half of India's new power supplies come from coal, and that could grow rapidly.

Traditionally, the coal sector was plagued by inefficiencies. State coal mines were notoriously dangerous and inefficient. Coal-fired plants in western provinces, far from the coal fields and vulnerable to the dysfunctional rail network, often came within days of shutting operations due to lack of coal.

All that is changing. Private and highly efficient coal mines are grabbing growing shares of the coal market. Upgrades to the nation's high-tension power grid is making it feasible to generate electricity with new plants installed right at the coal mines.

These improvements make coal the fuel to beat.

So the deal struck with President George W. Bush matters. At the moment, India has just 3 gigawatts of nuclear plants connected to the grid. Government planners envision that nuclear supply will grow to 30 GW over the next generation, but that will remain a fantasy without access to advanced nuclear technologies and, especially, nuclear fuels - such as those offered under the deal with the Bush administration.

By 2020, even after discounting for the government's normal exuberance in its forecasts, a fresh start for nuclear power could increase nuclear generating capacity nearly ten-fold.

By displacing coal, that would avoid about 130 million tons of carbon dioxide per year (for comparison, the full range of emission cuts planned by the European Union under the Kyoto Protocol will total just 200 million tons per year).

The effort, if successful, would eclipse the scheme under the Kyoto Protocol, known as the Clean Development Mechanism, that was designed to reward developing countries that implement projects to reduce their emissions of greenhouse gases. The largest 100 of these CDM projects, in total, won't reduce emissions as much as a successful effort to help India embrace safe nuclear power.

The benefits in slowing global warming are not enough to make the deal a winner. Care is needed to tame the risks of proliferation, especially those connected from India's system of breeder reactors that make more weapons-capable fuel than they consume. And complementary efforts, led by Indians, are needed to fix the trouble in India's electricity sector that have so far discouraged private investors.

None of this will be easy. There are no silver bullets in cooling the greenhouse.

What is important is that the deal is not just a one-off venture, as the administration's backers, on the defensive, have suggested. It could frame a new approach to technology sharing and managing a more proliferation proof fuel cycle that, in turn, will multiply the benefits of a cooler climate.

Coal-rich China is among the many other countries that would welcome more nuclear power and whose emissions of carbon dioxide are growing fast - even faster than India's.

Quite accidentally, it seems, the Bush administration has stumbled on part of an effective strategy to slow global warming. Now it should marry that clever scheme overseas with an effective plan here at home.

For nearly two decades, most major developing countries have struggled to introduce market forces in their electric power systems. In every case, that effort has proceeded more slowly than reformers hoped and the outcomes have been hybrids that are far from the efficiency and organization of the "ideal" textbook model for a marketbased power system.

At the same time, growing concern about global climate change has put the spotlight on the need to build an international regulatory regime that includes strong incentives for key developing countries to control their emissions of greenhouse gases. In most of these countries, the power sector is a large source of emissions that, with effort, could be controlled.

The United Nations Framework Convention on Climate Change and the Kyoto Protocol included mechanisms that would reward developing nations that cut emissions, but so far the performance of these mechanisms has fallen far short of their potential.

Beginning in 2002, the Program on Energy and Sustainable Development (PESD) at the Stanford Institute for International Studies (SIIS) and the Indian Institute of Management in Ahmedabad (IIMA) have conducted a set of studies to examine the intersection of these two crucial challenges for the organization of energy infrastructures in the developing world. This research, funded by the U.S. Agency for International Development, examined power-market reforms and greenhouse-gas emissions in two key states in India. At the same time PESD was conducting a comprehensive study of electricity-market reforms in five developing countries (Brazil, China, India, Mexico, and South Africa) as well as detailed analyses of the greenhouse-gas emissions from three provinces in China in conjunction with other research partners.

PESD and IIMA presented their findings at a workshop on January 27-28, 2005, at Stanford University. The workshop brought together scholars studying the organization of the electric-power sector and other infrastructures in developing countries with energy policy makers, technologists, and those studying the effectiveness of international legal regimes, with the aim of not only focusing on new theories that are emerging to explain the organization of the power sector and the design of meaningful international institutions, but also identifying practical implications for investors, regulators, and policymakers.

The workshop offered diagnoses of what has gone wrong and what opportunities have nonetheless emerged. It focused on practical solutions and a look at the prospects for different technologies to meet the growing demand for power while minimizing the ecological footprint of power generation.

One of the key conclusions of the research and the workshop, as discussed by David Victor, director of PESD, is that electricity markets in the developing world have not progressed inexorably and consistently from a state-owned model to an open market-based model. Rather, much as the experience of the past ten years in the United States has demonstrated, reform of electric-power systems has proceeded differentially between parts of the industry and between jurisdictional units, with some segments of the power generation, transmission, and distribution systems still dominated by the state and some segments now fully responsive to signals from the market.

This hybrid condition-with portions of the electricity enterprise deregulated and other portions still fully regulated-has proven to be virtually universal and quite durable as well. For the most part, it also has proven beneficial to the overall operation of the system as well as to climate mitigation due to the fact that introduction of market forces to parts of the system tends to have a spillover effect, helping to improve efficiency in parts of the system that remain under state control.

Tom Heller, SIIS senior fellow, noted that the negotiations leading up to the

development of the Kyoto Protocol and subsequent discussions and experience have

demonstrated that the burden-sharing metaphor-expecting developing nations to

make a proportional investment and effort in reducing greenhouse-gas emissions-

will not be successful. Rather, as gross and per capita energy consumption increases in developing nations, which is occurring especially rapidly in China and India, policies and mechanisms that facilitate investment in efficient and clean energy production, transmission, and end-use infrastructures will need to be developed and rolled out.

The Kyoto Protocol provided a Clean Development Mechanism (CDM) to encourage such investment. However, the conclusion reached by practitioners developing such projects in China is that CDM is an inefficient and insufficient mechanism for fostering the magnitude of development projects that will be required to help mitigate the environmental effects of energy growth in the developing nations.

Two problems with CDM were raised at the workshop. First, the bureaucratic hurdles facing developers of CDM projects are daunting. To date no such project has received certification. Second, the Kyoto Protocol's current round of reductions targets expires in 2012, and uncertainty regarding the likely direction and form of future U.S. and European initiatives provides a disincentive to investment in CDM projects.

Alberto Chiappa, managing director of Energy Systems International, noted the good news is that in spite of these difficulties, investors are finding opportunities to develop projects to provide cleaner sources of energy and improve end-use energy efficiency. Professor P.R. Shukla of IIMA pointed out that there is a great need to align development and climate concerns if future mechanisms for climate mitigation in the developing world are to be successful.

Douglas Ogden, program officer at the Energy Foundation, noted that China has made a firm commitment to greatly increase the market share of electricity from renewable sources to 5 percent by 2010 and 20 percent by 2020 and in 2008 will adopt an automobile fuel-economy standard 20 percent more efficient than U.S. CAFE standards. Also, both China and India are engaged in developing natural gas markets in sectors traditionally dominated by coal.

Mario Pereira, director of Power Systems Research, discussed Brazil's current efforts to develop economical and efficient electricity supply through biomass-specifically ethanol derived from sugarcane bagasse. The ethanol industry was originally developed as a reaction to the oil shocks of the 1970s. Although the majority of electricity in Brazil is provided by hydroelectric projects, sugarcane ethanol has some important advantages. First, the sugarcane fields are geographically close to major centers of demand, and second, sugarcane thrives during drier periods of the year when hydroelectric production declines. The experience in Brazil thus demonstrates that renewables can provide an economically attractive source of energy for developing nations.

Looking toward the future, PESD has several projects under way pertaining to the

intersection of electricity-market reforms and global climate change. The program is expanding its research on power-market reforms through a set of case studies on independent power producer projects in ten developing nations and is also initiating a set of studies examining the introduction of natural gas to regions in India and China.

Much work remains to be done before the interface between electricity-market reform and global climate change is well understood. As energy markets in the developing world expand, addressing this question will become more and more important if we are to stabilize atmospheric levels of greenhouse gases.

Energy Policy, one of the world's leading journals on issues related to energy economics and politics, has published an article by PESD researchers Chi Zhang, Michael May, and Thomas Heller this March documenting how changing incentives for power producers in three provinces have affected the types of plants built and operated, and the implications of those changes for emissions of carbon dioxide and other pollutants.
