This book analyzes the politics of global governance by looking at how global policymaking actually works. It provides a comprehensive theoretical and methodological framework which is systematically applied to the study of three global policies drawn from recent UN activities: the adoption of the Sustainable Development Goals in 2015, the institutionalization of the Human Rights Council from 2005 onwards, and the ongoing promotion of the protection of civilians in peace operations. By unpacking the practices and the values that have prevailed in these three cases, the authors demonstrate how global policymaking forms a patchwork pervaded by improvisation and social conflict. They also show how global governance embodies a particular vision of the common good at the expense of alternative perspectives. The book will appeal to students and scholars of global governance, international organizations and global policy studies.
