This innovative book promotes a holistic, pragmatic and proactive approach to just transitions. Arguing that justice is both a goal and condition of transitions it rearticulates environmental and social challenges and rethinks the policies designed to overcome them. Éloi Laurent succinctly explores the concepts, frameworks, policy designs, and emerging institutions of just transitions and maps its progress from philosophical streams, to academic fields, to public policies embedded in institutions. Chapters explore a broad spectrum of transition policies, including those aimed at mitigating environmental inequality caused by air pollution and heatwaves, and proactive social-ecological policies such as fair carbon taxation and just mobility regulations. He discusses key examples from across the globe, spanning from food security in France, to water justice in South Africa, to disaster risk reduction in South Asia. Just Transitions is an essential resource for academics and students specialising in environmental sociology, sociology, social justice, social policy and ecology. Its pairing of theoretical insight and practical examples will also benefit policymakers and stakeholders working in environmental sustainability, climate change and public policy more broadly.
