This article analyzes the EU, the United States and China's attitude about greenhouse gas abatement from the point of view of soft power. The conflicts of the above three countries or regions can not be explained rationally by hard power such as economy or military strength. Therefore, the annual climate conference can not effectively reach a consensus on greenhouse gas abatement by focusing on the standard of how to choose economic abatement tools and the allocation principle of carbon dioxide emissions rights. The essence of conflicts reflects national soft power contest, for example, the different acknowledges about the relationship of environment protection and economy, the value attractive and political guiding force, so to find out how soft power affect national economic policy of climate will help rise the efficiency of climate negotiation. On the other hand, as hard power is the physical carrier of soft power, both of them serve the maximization of national interests, thus the possibility of eliminate the conflicts is still exist by changing energy structure, seeking for new or substitute energy in order to develop new technology, provide new jobs and new profit growth. So when greenhouse gas abatement is closely linked with the mode of economic growth, the external problems of abatement will transform into internal problems of economic development, which makes global abatement activities possible.
