Combining theoretical and empirical approaches, this book examines the role that international public administrations play in global environmental politics in the Anthropocene. With chapters written by leading experts in the field, this text offers fresh insight into how international bureaucracies shape global policies in the complex areas of climate change, biodiversity, and development policy. International public administrations are thus recognized as partially autonomous actors with their own interests and motivations, assuming the roles of managers, orchestrators, brokers, or attention-seekers. This comprehensive resource provides scholars and practitioners with valuable insight into environmental policymaking and how international public administrations might be transformed to better address the multiple, fundamental challenges of our century.
