This paper measures accurately the CO2 embodied in international trade in China from 1995 to 2005 by constructing a non-competitive input-output model. The study shows that Chinese export brought about 1/4 to 1/3 of CO2 emissions in production while import fulfilled 1/5～1/4 of CO2 emissions in consumption. The proportion of CO2 embodied in Chinese net export of those in production increases gradually. China has shared a great deal of CO2 emissions for foreign countries. In addition, China has saved more and more CO2 because of import of intermediate input. From the perspective of industry structure, China’s foreign trade facilitates CO2 emissions reduction and the pollution terms of trade become slightly better, but the contribution for foreign trade to CO2 emissions reduction decreased from 2 000. Therefore, in order to reduce the pressure of CO2 emission, China should control the scale of export and adjust the structure of international trade pertinently.
