Increasingly, environmental rights are being recognized as enforceable human rights, both substantive and procedural. Environmental law can no longer be viewed merely as a matter for policy choices in legislation. This new casebook shows how international and national court cases in Europe, Africa, Asia, and the Americas have begun to interpret treaties, national constitutions, and human rights legislation to protect the environment through the recognition of rights. For the first time, these rich developments are brought together in a book suitable as a primary text for classes and seminars.
