This book explores how EU law constrains the freedom of the EU, the Member States, and private bodies to adopt measures that seek to protect social and environmental interests abroad by placing conditions on production processes in other states. The permissibility of such process-based measures has been examined primarily within the World Trade Organization (WTO) context, but the challenges that they present are equally for the EU internal market system. Ankersmit identifies three core challenges posed by process-based measures from an EU law perspective: extraterritoriality, unilateralism and the competitive and democratic problems created by private rule-making. It examines these issues in the context of free movement, competition, public procurement, and EU tax law. This book will appeal to academics, policy makers and practitioners interested in trade and environment, the social impact of trade law, and European and international market regulation.
