In this thoughtful and original book, social scientist Olivier Godard considers the ways in which arguments of justice cling to international efforts to address global climate change. Proposals made by governments, experts and NGOs as well as concepts and arguments born of moral and political philosophy are introduced and critically examined. Godard contributes to this important debate by showing why global climate justice is still controversial, despite it being a key issue of our times.Godard first points out the huge differences between the foundations of conflicting proposals, for instance between a cosmopolitan viewpoint and an international one. He then explores controversies over climate justice proposals and provides a rigorous criticism of those based on historical responsibility. Finally, he demonstrates how issues of justice are reconfigured by instrumental regimes of coordination, such as a global carbon market. Inspired by the French school of justification, this book shines an insightful light on the failure of climate change debates to develop a convincing standard moral and political theory.Including elements from systems theory, economics and law, this book will be of interest to scholars and students of moral and political philosophy, economics and social sciences, as well as experts working on climate negotiations and concerned stakeholders.
