There is growing evidence that providing businesses and consumers with market-based mechanisms for addressing environmental problems can achieve equal or better compliance while reducing costs and spurring technological innovation. In the context of climate change, countries have agreed to use several market-based mechanisms in implementing greenhouse gas emissions reductions-from emissions trading similar to that used in the United States to reduce sulfur dioxide emissions to more experimental measures such as joint implementation and the Clean Development Mechanism.

This report, which analyzes market-based environmental policy instruments, is the third in a series by the Center. The Pew Center was established in 1998 by the Pew Charitable Trusts, one of the nation's largest philanthropies and an influential voice in efforts to improve the quality of America's environment. The Center brings a new cooperative approach and critical scientific, economic and technological expertise to the global climate change debate. The report was prepared as an input for the participants of two international conferences designed to promote a trans-Atlantic dialogue on market-based instruments and their use in mitigating global climate change. Recognizing the critical role of business in both shaping and applying market-based mechanisms, the Pew Center is working to bring businesses from both the United States and Europe together to discuss ways to do so.

The report reviews U.S. and European experience with market-based mechanisms and the ways the Kyoto Protocol on Climate Change utilizes these mechanisms. The report finds that properly designed rules for the operation of these mechanisms can provide economic and environmental integrity and signal to business and governments that any trades undertaken in accordance with the system will be valid and of value. Key elements to the success of such a system will be measurement, transparency, accountability, fungibility and consistency.

The Pew Center and its Business Environmental Leadership Council believe that climate change is serious business. Implementing emissions trading and other market-based mechanisms will be part of a serious response to the climate change problem.

Executive Summary

This paper has been developed with a view toward promoting trans-Atlantic dialogues on market mechanisms for environmental protection. While the overarching topic for dialogue is the full panoply of environmental problems for which market mechanisms may be considered, this paper is prepared in the context of increasing global attention to the problem of climate change. The November 1998 Buenos Aires Conference of the Parties to the United Nations Framework Convention on Climate Change provides an example of the international focus on market mechanisms among governments, the private sector, and non-governmental organizations around the world.

This paper reviews market mechanisms for environmental protection, with special focus on emissions trading. Emissions trading programs place an overall limit on the amount of emissions that sources may emit, and then allow sources a degree of flexibility to determine where, when, and how to meet their total limits. Emissions trading programs provide this flexibility by allocating to sources a fixed amount of emissions allowances; any source that reduces emissions below allowable levels may save the resulting allowance increment to offset future emissions, or sell the increment to another source who may add the increment to its allowances. Compliance is determined solely by comparing actual emissions to allowable amounts.

The paper notes that five elements are essential for providing environmental and economic integrity in such programs: measurement, transparency, accountability, fungibility, and consistency. In reviewing the experiences of the U.S., New Zealand, and Europe, the paper finds that harnessing the competitive forces of the market-place in favor of pollution reduction can enable governments, industries, and non-governmental organizations (NGOs) to reach political consensus about pollution limits. Experience also indicates that when these elements are firmly in place, emissions trading programs can deliver powerful incentives to sources to innovate to develop more environmentally effective and more cost-effective ways of reducing emissions. Trading programs premised on these elements can achieve faster, deeper cuts in pollution, at far less cost than other regulatory instruments.

The 1997 Kyoto Protocol on Climate Change seeks to use market mechanisms to limit the emissions of greenhouse gases (GHGs) that are contributing to changes in the global climate. The paper examines the Kyoto Protocol framework for an innovative international market in GHG emissions reductions. The Protocol places a legally binding limit on the allowable amount of GHG emissions from most industrialized countries for the period 2008-2012. It then affords these nations the opportunity to trade allowable amounts of emissions, either directly or in conjunction with joint emissions reduction projects. It further allows these nations to implement their obligations collectively, through shared arrangements known as "bubbles" or "umbrellas."And the Protocol invites the participation of nations that have not adopted a legally binding GHG limit: it allows a limited form of trading between nations with limits and those without, where the trading involves emissions reductions obtained through cooperative projects in the latter group of nations.

The paper notes that the Kyoto Protocol respects the sovereignty of each participating nation to determine how best to implement its international obligations at the domestic level, and whether, in so doing, it should allow its private sector to participate in the international emissions trading market. The Protocol leaves open the development of internationally agreed rules to provide the transparency, the accountability, and-particularly in the case of trading with nations lacking limits on GHG emissions-the measurability that may be key to the Protocol's success. Further, the Protocol allows each nation that adopts emissions limits to decide whether to initiate programs prior to 2008 that will provide recognition and incentives for early actions to reduce emissions. The Protocol does not address the question of whether nations will, individually or collectively, place quantitative or qualitative restrictions on emissions trading.

After exploring the theory of market mechanisms, examining their implementation in selected cases, and analyzing the market elements of the Kyoto Protocol, the paper draws on lessons learned from practical experience in order to identify and evaluate options on the questions left open by the Protocol. The paper indicates that for environmental and economic effectiveness, experience weighs in favor of a limited set of rules-carefully drawn to foster measurement, transparency, accountability, fungibility, and consistency-and weighs against imposing further restrictions on the market mechanisms.

This report was one input into two conferences on market-based mechanisms, which were held on 23 and 27 October, 1998, in Bonn and Paris. The conferences provided an important forum in which participants, including representatives of businesses, non-governmental organizations, and governments, shared practical experience about the use of market mechanisms, and provided valuable insights about the trans-Atlantic context for consideration of the report's findings.
