This book presents a new framework for the trade and environment debate and discusses the ways in which the EU and the WTO address this topic: positive, negative and non-integration. It analyses areas like food safety and renewable energy from the perspectives of legal and political science, and economics, and includes contributions focusing on various approaches, such as harmonisation, regulatory cooperation and judicialisation. In the 21st century, especially in our current times, where free trade and economic integration are increasingly being called into question, it is even more vital to find convincing normative answers and ways to address the very complex relationship between trade and environmental policies. Debunking some of the myths concerning positive and negative integration and the relationship between the two, this book is a valuable contribution to the debate on globalisation.
