This volume presents an overview of public environmental law in the EU and the US. It focuses on constitutional and administrative environmental law but also includes other areas of law such as criminal and private law (in as far as these are relevant to the understanding of public environmental law).;The book offers a comparative introduction, by editors and native authors, to the most important aspects of environmental law (prevention of pollution). It thus aspires to contribute to both ""transboundary"" understanding of different regimes for Environmental Law and to a greater co-operation between different international and European partners in their strive towards more adequate (legal) modes of protection and improvement of the environment.
