This new and fully updated edition of Principles of International Environmental Law offers a comprehensive and critical account of one of the fastest growing areas of international law: the principles and rules relating to environmental protection. Introducing the reader to the key foundational principles, governance structures and regulatory techniques, Principles of International Environmental Law explores each of the major areas of international environmental regulation through substantive chapters, including climate change, atmospheric protection, oceans and freshwater, biodiversity, chemicals and waste regulation. The ever-increasing overlap with other areas of international law is also explored through examination of the inter-linkages between international environmental law and other areas of international regulation, such as trade, human rights, humanitarian law and investment law. Incorporating the latest developments in treaty and case law for key areas of environmental regulation, this text is an essential reference and textbook for advanced undergraduate and postgraduate students, academics and practitioners of international environmental law. --
