Environmental regulation in the United States has succeeded, to a certain extent, in solving the problems it was designed to address; air, water, and land, are indisputably cleaner and in better condition than they would be without the environmental controls put in place since 1970. But Daniel Fiorino argues in The New Environmental Regulation that—given recent environmental, economic, and social changes—it is time for a new, more effective model of environmental problem solving. Fiorino provides a comprehensive but concise overview of U.S. environmental regulation—its history, its rationale, and its application—and offers recommendations for a more collaborative, flexible, and performance-based alternative.
