Paths to a Green World: The Political Economy of the Global Environment. Cambridge, MA: MIT Press, 2005. ISBN 0262532719 $25.00 Paper $62.00 Cloth. (327p.) A contribution to the undergraduate environmental studies literature, Paths to a Green World: the Political Economy of the Global Environment, provides a summation of the issues surrounding the global economy and its relationship to environmental issues. The authors, Jennifer Clapp, also the author of Toxic Exports: the Transfer of Hazardous Wastes from Rich to Poor Countries (Cornell University Press, 2001), and Adjustment and Agriculture in Africa: Farmers, the State, and the World Bank in Guinea (St. Martin's Press, 1997), and Peter Dauvergne , the author of Handbook of Global Environmental Politics (E. Elgar, 2005), use four sometimes-competing worldviews to inform Paths. Using these four worldviews serves to structure policies and debates that surround globalization, global institutional analysis, transboundary pollution, (free) trade, development, labor, gender equity, investment, debt relief, sustainability, and poverty. The four general worldviews, which are explained by the authors as “ ‘ideal’ categories exaggerated to help differentiate” are classified as market liberals (“benefits and dynamics of free markets and technology”), institutionalists (“emphasize the need for stronger global institutions and norms”), bioenvironmentalists (“stress the limits of earth to support life”), and social greens (“see social and political problems as inseparable”). In creating these “ideal” categories, the authors state they are simplifying “a seemingly unmanageable avalanche of conflicting information and analysis.” (p. 3). However, in describing the “ideal” categories, it would be useful for undergraduate readers, and readers generally, to be offered a brief theoretical discussion of what constitutes an “ideal,” by which I assume the authors are referring to Max Weber’s concept of ideal type. 1 This, and concepts such as environmental discourse 2 , are simply not defined by the authors. In the case of environmental discourse, a mere footnote to John S. Dryzek’s The Politics of the Earth : Environmental Discourses (New York : Oxford University Press, 2005) is provided, which hardly contributes to an understanding of the theoretical underpinning and methodological application of discourse, or its relevance to the language, politics, policies, and practices of economic players such as the World Bank, International
