The planetary boundaries framework - one of the most influential ideas of our age - is used to describe human-Earth relationships. It shapes global environmental policy and new economic thinking. This book takes a multidisciplinary approach to the planetary boundaries framework. It consists of eighteen chapters by scholars from disciplines ranging from international law to indigenous knowledge. Each chapter begins with an introduction before expanding into a critical analysis of the reach and limits of the boundary framework itself, with each of the nine frameworks the focus of two chapters. This volume comes at as a critical moment, when the unprecedented challenges of the climate crisis demand new approaches, tools and perspectives to questions of climate justice and sustainability. It is a valuable resource for researchers and graduate students in environmental politics and ethics, geography, and Earth system science.
