Since its inception in the 1970s, German environmental policy has continuously evolved. This pertains to the range of regulated issue areas, the instruments used, as well as the environmental policy outcomes. The present introduction examines German environmental policy from a policy field analytical perspective and offers explanatory factors, particularly the underlying problem structures of environmental policy, its key actors, and institutions. These considerations are consolidated in a concluding theoretical chapter on environmental policy processes, which aims to provide students and researchers with an analytical tool for the examination of specific environmental policy cases. The volume was developed as a course for BA students at the FernUniversität in Hagen and combines scientific state-of-the-art standards with good comprehensibility.
