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.
