- Climate change — Environmental disputes — Specific treaties — Treaties, observance
This introductory chapter provides an overview of international climate change law. It begins by discussing the factors that make climate change a challenge for international policymakers. The chapter then looks at three perspectives that have dominated the international policy response to climate change — climate change as an environmental problem, as an economic problem, and as an ethical one. In addition, it charts out the broad scope of international climate change law into a vast and complex web of principles, rules, regulations and institutions that will henceforth be referred to as ‘the UN climate regime’. The chapter also tackles the recurring themes and subject matter of international climate change law, before turning to the ways in which international climate change law engages with a multitude of treaty regimes, actors, and other international bodies.
