Corporate Social Responsibility has for long been on the agenda in the business world and recently, it has also become a political agenda in the European Union. Focusing on international supply chains and their control based on studies of law in several European jurisdictions, this book aims to advance the discussion on the application and enforcement of CSR. Drawing parallels to US and Canadian law, the book explores to what extent private law tools can be used as an enforcement device and it ultimately asks if what we are witnessing is the formation of a new area of law, employing the interplay of contract and tort - a law of "production liability", as a corollary of the concept of "product liability".
