Trump will use the withdrawal to build his political reputation and to renegotiate the Paris Agreement despite its negative effects on the political credibility, international relationships, and potential long-term economic growth of the U.S. In general, the withdrawal of the U.S. from the Paris Agreement will not change the development of low-carbon technologies and the transformation trend of the global climate governance regime. However, the long-term goals and international cooperation on climate change will be affected by budget cuts in American climate change research and the cancelation of donations from the multilateral environmental fund of the U.S. If the Paris Agreement is renegotiated, the common but differentiated principle of responsibility of the United Nations Framework Convention on Climate Change will be challenged again. Nevertheless, climate change governance remains a main theme of future sustainable development. Instead of national governments, local governments and non-governmental organizations will develop strategies for technical innovation and emphasize pragmatic cooperation, thus expanding their roles in climate change governance. The capacity building on climate change research and public awareness should be enhanced as a long-term objective of global climate change governance.展开更多

An analysis of their relations in global climate governance is of great significance both for global multinational negotiations and their bilateral relations. The two parties have enhanced their cooperation on climate change since 2009 in terms of increasing willingness, broader scale, more diverse mechanisms and higher effectiveness. With the U.N. Paris Climate Conference 2015 approaching, China-US cooperation will inject much momentum into the multilateral process of reaching an ambitious agreement. However, there are also sharp divergences between China and the U.S. regarding principles, rules, and legal means. These divergences might become prominent during the Paris Conference and need to be addressed at the bilateral level.展开更多
