As climate redefines economic policymaking, climate policies are reshaping the foundations of international trade law-and this book reveals how. In Climate Change in International Trade Law, the author provides an authoritative account of the emerging trade regime governing green subsidies, carbon pricing, and deforestation-free regulations beyond WTO disputes. It argues that novel rules redefine core trade law principles, increasingly linking market access to climate performance. It shows these rules interacting, revealing their transformative potential, legal and political limits. Drawing on practical experience with EU CBAM, deforestation regulations, and EU-Mercosur sustainability negotiations, it offers actionable insights for climate-aligned, equitable, coherent trade-policymaking. Essential for scholars, practitioners, and policymakers, it provides a systemic account of trade law's evolving role in climate governance and how it can drive mitigation, address inequalities, and help industries -particularly in developing countries-navigate today's changing trade landscape.
