Climate change will bring great suffering to communities, individuals and ecosystems, with those least responsible for the problem suffering the most. Justice demands urgent action to reverse its causes and impacts. In this provocative new book, Paul Harris brings together a collection of original essays to explore alternative, innovative approaches to understanding and implementing climate justice in the future. Through investigations informed by philosophy, politics, sociology, law and economics, this book reveals how climate change is a matter of justice and makes concrete proposals for more effective mitigation.
