The Kyoto Protocol is the most substantial international development in climate politics since the signing of the original United Nations convention in 1992. Short commentaries on the Kyoto Protocol abound, but this is the book-length treatment that will be the definitive guide for years to come. In addition to covering the background and negotiations that produced the protocol, the book gives an enormously detailed account of the various innovations made by negotiators at Kyoto. Thus, there is substantial discussion of the Clean Development Mechanism, joint implementation, and the specific emissions reduction targets adopted at Kyoto. The book also discusses the political dynamics of the negotiations and the political forces that are likely to influence the future of the climate change regime. While the authors’ attempts to place this in the context of globalization are a little simplistic, the focus on the realpolitik of interstate bargaining on climate change is a useful addition to the great technical det ail contained in this book. It is an enormously valuable resource for students of environmental politics.
