This book provides a comprehensive introduction into the making, development and implementation of European Union (EU) environmental politics. The environmental policy of the EU has made impressive progress during the last three decades. Starting off as little more than a by-product of economic integration, it has developed into a central area of EU policy making. The book explores the driving forces behind this development, identifying the central areas and instruments of EU environmental policy, and analyses the factors influencing not only the formulation, but also the implementation, of environmental measures in the complex multi-level setting of the EU. On this basis, it takes a critical look at the EU's effectiveness and problem-solving capacity in the environmental field, employing an analytical perspective based on the theoretical state of the art of EU policy studies. Thus, the book provides an overview of the major theoretical approaches available in the field. At the same time, the discussion is illustrated by a broad range of empirical findings with regard to the formulation and implementation of EU environmental policy.
