International Environmental Law is a new textbook written for students, practitioners, and anyone interested in the subject. The overall aim of the book is to provide a fresh understanding of international environmental law as a whole, seen in the light of climate change, biodiversity loss, and the other serious environmental challenges facing the world. The book has also been kept deliberately manageable in size by careful selection of topics and by adopting a cross-cutting synthesis of regulatory interaction in the field. This enables the reader to place international environmental law in the broader context of public international law in general, revealing at the same time that international environmental law is experimental ground for developing new legal approaches towards global governance. To this end, the authors have combined theory and practice.Apart from discussing concepts, rule-making and compliance, the book looks at options for improved coordination, harmonisation and even integration of existing multilateral environmental agreements, analysing how conflicts between various environmental regimes can be avoided or, at least, adequately managed. The authors argue that an appropriate management of international environmental relations must address the North-South divide, which continues to be a major obstacle to global environmental cooperation. Furthermore, the authors emphasise the growing human rights dimension of international environmental law.This book is an ideal ‘door opener’ for the further study of international environmental law. Focusing on ‘international environmental governance’ in a comprehensive way, it serves to explain that each institution, each actor, and each instrument is part of a multi-dimensional process in international environmental law and relations.
