This timely book addresses the interaction between policies addressing climate change and the rules of the WTO. The authors expertly examine the law and economics behind the application of trade rules in the area of climate, including the implications of WTO rules for domestic climate measures, the unilateral use of trade measures to attempt to force other countries to take climate action, and the role of trade measures in multilateral climate agreements. The book argues that while there is a possibility of conflict between international trade rules and progress on climate change, it need not be the case. Thus the major focus is on the ways in which trade measures can aid in addressing climate change.
