This course examines the design and implementation of international policy relating to climate change, biodiversity conservation, and other pressing environmental challenges. Through a case study approach, we will consider how treaties, standards, and programs leverage information, incentives, and institutions to promote sustainability transitions. We will focus in particular on how national governments, corporations, non-governmental organizations, foundations, and local populations shape the formulation and implementation of environmental policy. Students will learn about major issues and concepts in international environmental governance and acquire skills in designing, analyzing, and communicating policy interventions.
