The author integrates ancillary benefits into the theory and explores the implications for international policy measures. Because of the private character of ancillary benefits, the author is able to treat climate policy as an impure public good which in turn has an impact on the efficient climate protection level. He highlights the general failures of the standard approach to climate policy design and goes on to propose a new approach to international negotiations on climate change. He suggests a flexible matching scheme which would help overcome free-rider incentives and which would have considerable advantages over traditional co-operative designs.

By proposing a novel framework for the analysis of, and solution to, the problem of global warming, this book will be welcomed by environmental and ecological economists, policymakers and researchers of political science.
