Abstract

This chapter studies how the scope of global politics has been extended over the last half century or so to include the impact of human industrial activity on the environment. The environmental movement and ‘green theory’ have grown out of concerns with the deleterious impact of this activity and the capacity of the planet to carry the burden of ‘business as usual’ in a world driven by the imperatives of endless growth. Many now believe that the impact on the earth’s systems is so significant that the present geological period should be recognized as the ‘Anthropocene’. Climate change is probably the most prominent issue associated with the Anthropocene at present, but it is not the only one. The chapter examines a range of issues in global environment politics, starting with the reconceptualization of the present period. It then moves on to an account of the environmental movement, the emergence of various ‘green’ ideologies and theories, and the politics of science. This is essential background for considering the role of the state and its sovereign powers in the context of global environmental politics.
