The overarching objective of this project is to contribute to the development of a multilateral policy framework for collaborative or "joint" implementation between countries of the United Nations Framework Convention on Climate Change by examining the roles of Japan, the United States and China in developing regional and global solutions to the climate change problem. In order to achieve this objective, I propose to (1) compare the national approaches of Japan, the US and China to climate change, including policies concerning collaborative or "joint" implementation of activities to prevent climate change, (2) view these policies in the context of the global climate change regime, (3) examine the opportunities for bilateral and trilateral cooperation among Japan, the US and China to address the climate change problem, and ( 4) evaluate these countries' roles as both models and catalysts in developing a global framework on joint implementation of the Climate Change Convention.
