Book excerpt: This second edition of Philippe Sand's leading textbook on international environmental law provides a clear and authoritative introduction to the subject, revised to December 2002. It considers relevant new topics, including the Kyoto Protocol, genetically modified organisms, oil pollution, chemicals etc. and will remain the most comprehensive account of the principles and rules relating to environmental protection and the conservation of natural resources. In addition to the key material from the 1992 Rio Declaration and subsequent developments, Sands also covers topics including the legal and institutional framework, the field's historic development and standards for general application. This will continue to be an invaluable resource for both students and practitioners alike.
