The Harvard Project on International Climate Agreements is a global, multi-disciplinary effort intended to help identify the key design elements of a scientifically sound, economically rational, and politically pragmatic post-2012 international policy architecture for addressing the threat of climate change. It has commissioned leading scholars to examine a uniquely wide range of core issues that must be addressed if the world is to reach an effective agreement on a successor regime to the Kyoto Protocol. The purpose of the project is not to become an advocate for any single policy but to present the best possible information and analysis on the full range of options concerning mitigation, adaptation, technology, and finance. The detailed findings of the Harvard Project are reported in this volume, which contains twenty-seven specially commissioned chapters. A companion volume summarizing the main findings of this research is published separately as Post-Kyoto International Climate Policy: Summary for Policymakers.
