In 2015, the United Nations formulated 17 ambitious goals towards transforming our world - the Sustainable Development Goals (SDG 2030). Their relation to public international law has been studied, but private law has received less attention in this context and private international law none at all. Yet development happens - not only through public action but also through private action, and such action is governed predominantly by private law and private international law. This book demonstrates an important, constructive role for private international law as an indispensable part of the global legal architecture needed to turn the SDGs into reality. Renowned and upcoming scholars from around the world analyse, for each of the 17 SDGs, what role private international law actually plays towards these goals and how private international law could, or should, be reformed to advance them. Together, the chapters in the book bring to the fore the hitherto lacking private side of transforming our world.
