This textbook provides a solid introduction to the theoretical and empirical aspects of environmental economics, and their links to environmental policy. It advocates drawing on the economist's toolbox as a powerful means of finding solutions to environmental problems by addressing the conflict between the societal costs of pollution on the one hand, and the financial costs of emissions reduction on the other. The book presents the main economic theory approaches to handling environmental problems and assessing the monetary value of environmental quality; the most relevant environmental policy instruments and challenges involved in their effective real-world application; and both national and global environmental problems addressed by environmental negotiations and agreements. Given its scope, the book offers a valuable basis of information for students, and for policymakers pursuing effective environmental policies.
