Even as the evidence of global warming mounts, the international response to this serious threat is coming unravelled. The United States has formally withdrawn from the 1997 Kyoto Protocol; other key nations are facing difficulty in meeting their Kyoto commitments; and, developing countries face no limit on their emissions of the gases that cause global warming. In this clear and cogent book-reissued in paperback with an afterword that comments on recent events - David Victor explains why the Kyoto Protocol was never likely to become an effective legal instrument. He explores how its collapse offers opportunities to establish a more realistic alternative. Global warming continues to dominate environmental news as legislatures worldwide grapple with the process of ratification of the December 1997 Kyoto Protocol. The collapse of the November 2000 conference at the Hague showed clearly how difficult it will be to bring the Kyoto treaty into force.Yet most politicians, policymakers, and analysts hailed it as a vital first step in slowing greenhouse warming. David Victor was not among them. Kyoto's fatal flaw, Victor argues, is that it can work only if emissions trading works.The Protocol requires industrialized nations to reduce their emissions of greenhouse gases to specific targets. Crucially, the Protocol also provides for so-called 'emissions trading', whereby nations could offset the need for rapid cuts in their own emissions by buying emissions credits from other countries. But starting this trading system would require creating emission permits worth two trillion dollars - the largest single invention of assets by voluntary international treaty in world history. Even if it were politically possible to distribute such astronomical sums, the Protocol does not provide for adequate monitoring and enforcement of these new property rights.Nor does it offer an achievable plan for allocating new permits, which would be essential if the system were expanded to include developing countries. The collapse of the Kyoto Protocol - which Victor views as inevitable - will provide the political space to rethink strategy. Better alternatives would focus on policies that control emissions, such as emission taxes. Though economically sensible, however, a pure tax approach is impossible to monitor in practice. Thus, the author proposes a hybrid in which governments set targets for both emission quantities and tax levels. This offers the important advantages of both emission trading and taxes without the debilitating drawbacks of each. Individuals at all levels of environmental science, economics, public policy, and politics - from students to professionals - and anyone else hoping to participate in the debate over how to slow global warming will want to read this book.
