'Principles of International Environmental Law remains the definitive treatise on this vitally important area of international law. The international community faces unprecedented environmental challenges and this work provides a comprehensive assessment of the capacity of environmental norms and institutions to address these threats. The work is an essential reference for anyone interested in the role of international law in preserving a safe operating space for humanity and the environmental systems we depend on in the Anthropocene.' Tim Stephens, University of Sydney Law School 'This book makes one reality brutally clear - that international environmental law cannot and must not be viewed as a subject for international lawyers, scholars, and students to alone savour. Rather, this book illuminates the complex, and often-hidden, ways in which international environmental law permeates both the study and practice of law much more generally. Simply put, this is exactly the book that will allow international environmental law to escape its specialist field billing and to capture the wide attention of all those seeking to understand law and its relationship to the future of this planet.' Natasha Affolder, University of British Columbia 'International environmental law continues to grow in significance and complexity. This new edition by two of the leading contemporary experts in the field is welcome and timely. It provides what must be the most comprehensive and accessible account of the key treaties relating to the environment and the underlying environmental principles of international law. The treatment of international trade and investment law as it affects the environment is especially valuable.' Richard Macrory, Emeritus Professor of Environmental Law, University College London 'This is a 'must have' volume for all interested in international environmental law. It is remarkable in its scope and ambition. It locates the subject within the broader framework of public international law and is attuned to contemporary developments in governance practice and theory as well as law. One can only wonder at the breadth of knowledge and insight of the authors.' Joanne Scott, European University Institute, Florence 'This fourth edition of Principles of International Environmental Law firmly establishes this classic text as the authoritative guide for academics, practitioners and students alike. Written in an accessible manner and clearly structured, this book offers a comprehensive overview of the rules of public international law that have environmental protection as their goal. The authors have succeeded in striking the right balance between breadth of coverage and analytical depth. This book is, indeed, a treasure trove of knowledge and information.'
