This leading monograph on European Environmental Law is now completely updated and revised. Taking into account new case law of the European Courts, recent environmental directives and regulations and the new provisions of the Lisbon Treaty. This book provides an in-depth analysis of important legal issues of European environmental law. What are the legal grounds for EU environmental policy and on what principles are directives and regulations based upon? To what extent precludes EU environmental regulation more stringent national environmental standards? What are the requirements the Court of Justice has imposed on the Member States implementing environmental directives? How and to what extent can European environmental law be relied upon and challenged before national courts and the European Courts? How do the Treaty rules on the internal market and undistorted competition interfere with national environmental policy? Answers to these and other questions can be found in this book. The book discusses all major environmental directives and regulations, integrating important judgments of the Court of Justice on their interpretation. Furthermore, national case law on the application of European environmental law is also being taken into account.
