This chapter explores international law relating to the protection of the environment, a relatively new field of international law that covers a broad range of concerns. The pollution of the oceans and the seas, the extinction of animal species, deforestation, and climate change: these are all concerns addressed by international environmental law. This chapter begins by providing a brief overview of the evolution of international environmental law and explains the principal characteristics of this field of international law. It further considers the interrelationship with the concept of sustainable development, which is central to modern approaches toward protecting the environment. It then explores two of the principal concerns addressed by international environmental law: first, the conservation of flora and fauna; and, second, the prevention of pollution and related environmental harm. Furthermore, the chapter discusses compliance and enforcement mechanisms. Lastly, because environmental protection measures often have implications for international trade, it briefly deals with the interrelationship between international environmental law and trade law.

Chapter 5 examines the rebuilding of the global environmental movement after the Second World War. Environmental protection did not become one of the core objectives of the newly created United Nations. It was not until the ‘environmental revolution’ of the 1960s, which transformed environmentalism from an elite concern into a mass movement with wider electoral consequences for governments, that international society began to accept environmental stewardship as a new primary institution. Within a short space of time, from the mid-1960s until the early 1970s, leading industrialised economies established environmental protection first as a comprehensive domestic duty of the state and then as a general responsibility for international society. The 1972 Stockholm conference, the first UN conference on the environment, became the equivalent of a ‘constitutional moment’ in the greening of the international normative order. This chapter traces the process through which world society actors successfully transmitted environmentalism into international society, with leading powers such as the United States providing critical leadership along the way.
