This timely book explores the contribution of international human rights and investment law to advancing climate action. It presents a unique perspective on climate change in an international law context, analyzing areas of law that are critical to the achievement of the Paris Agreement’s goals in the absence of sufficient state ambition. Bringing together diverse trends and approaches, expert authors explore the opportunities and challenges of climate change in relation to human rights and investment law, illustrating the evolution of normative standards, litigation and law-making through this framework. Chapters assess the impact of normative reforms that aim to better incorporate climate commitments, the role of adjudication in ensuring the enforcement of such obligations, and the processes leading to the adoption of new climate-friendly agreements. Ultimately, both human rights and investment law are shown to both support and undermine climate considerations against the background of a marked uptick in climate-related litigation in these fields. Identifying solutions to advance international legal action on climate change, this book is a crucial resource for scholars and students of environmental, international investment, and human rights law. Practitioners and policymakers will also benefit from the practical and theoretical insights.
