This book provides a comparative analysis of environmental regulation in multi-jurisdictional legal and political systems, focusing on the United States, the European Union, and the international community. Each of these systems must deal with environmental interdependencies that cross local borders, in some cases creating regional problems, such as acid deposition, ozone type smog, and pollution of shared water bodies. Some transjurisdictional environmental problems are global, including stratospheric ozone depletion, climate change, and the loss of biodiversity. Other environmental problems, however, are localised in their effect on health and the environment.
