Annotation * Comprehensive examination of the compliance system of the UN Framework Convention on Climate Change and the Kyoto Protocol * Covers development and design of the system, obstacles to its effectiveness, the role of state and non-state parties and the importance of trade measures and other factors for compliance * Contributions from leading international political scientists, lawyers, economists and natural scientists to this crucial aspect of climate policy The international climate regime is only as good as the compliance mechanisms that ensure its effectiveness. This book is the first thorough evaluation of its compliance system, assessing its robustness and ability to cope with internal and external pressures and obstacles to meaningful compliance by national governments and other bodies such as business and industry affected by climate treaties. It covers four main themes: a comparative analysis of the formation and structure of the compliance system and the controversies that surrounded it;verification and its ability to respond to climate-specific challenges and obstacles; how external compliance mechanisms such as trade measures can work alongside internal ones; and the role of corporations and NGOs in its implementation. This will be the authoritative treatment of this essential aspect of the regime to deal with the major challenge facing the international community.
