This introductory chapter presents global environmental politics as an important area of international and transnational cooperation and as a distinct field of study. First, as an area of cooperation, global environmental politics emerged out of the need to work together internationally and transnationally to address some pressing environmental problems, such as biodiversity loss, climate change, the depletion of the ozone layer, and the rapid reduction of global fish stocks. Independent state action at the local and national levels is not sufficient to address global environmental issues: these issues require cooperation through global governance. Second, as a field of study, global environmental politics investigates the various dimensions of emerging actions on global environmental issues. It is a diverse field of study from both theoretical and disciplinary perspectives.
