This timely Research Handbook offers an insightful review of how legal systems – whether domestic, international or transnational – can and should adjust to fairly and effectively support loss and damage (L&D) claims in climate change law. International contributors guide readers through a detailed assessment of the history and current state of L&D provisions under the UN climate regime and consider the opportunities to fund L&D claims both within and outside the UN climate system. Split into four parts, the Research Handbook investigates the current legal frameworks for L&D across both public international law and domestic law. Chapters explore foundational issues including equity and justice and give a critical assessment of the current state and potential future evolution of international legal systems. The contributing authors also discuss the challenges faced by different legal systems in dealing effectively and fairly with L&D.Providing a comprehensive overview of this important topic, this Research Handbook will be an excellent resource for climate lawyers and policymakers. It will also be an invaluable read for academics and students researching environmental and climate issues.
