Climate Change Law, the first volume of the Elgar Encyclopedia of Environmental Law, provides a guide to the rapidly evolving body of legal scholarship relating to climate change. This book focuses on concepts that are of concern to researchers, students and policymakers rather than on the details of national legislation. It provides a comprehensive discussion, with more than 50 structured entries developed by experts from across the world. The coverage sets mitigation and adaptation issues in their wider context, using both international and national perspectives. The core topics include the difficulty of setting up a coherent international treaty approach, the importance of national and subnational legal action, the potential role of international and national courts, and the importance of human rights and environmental justice.
