"The new edition of this essential book details the present state of EU environmental law as it has developed over the last 50 years. The author was personally involved in its making and enforcement, having worked for more than 30 years in the environmental department of the European Commission. The book provides therefore unique insights into this complex field. New chapters elaborate on the relationship between UK and EU law after Brexit (written by Christopher Badger) and on the global effect of EU environmental law and policy. The book is indispensable reading for students, researchers, and practising lawyers alike"--
