The global greenhouse effect may be one of the greatest challenges ever to face humankind. Policies in the developed countries aimed at the reduction of nationally produced CO2 emissions may result in the relocation of emission intensive industries into poor countries with less stringent policies. This relocation often not only leads to a simple relocation of emissions, but to an absolutely increase of emissions due to a less advanced technology in the poor countries and the failure of global greenhouse gas emissions reduction target. To overcome this difficulty, based on input-output technology, consumption-based approach to account for all the emissions attributable to the final activities of a country has been widely employed. China has been the 1st place of CO2 emissions in the world. Behind the rapid increase of CO2 emissions in China, there is the fast expansion of foreign trade in China. The study on relationship between trade and CO2 emissions could help the government understand the origin sources of CO2 emissions and make better CO2 emissions reduction policies to respond global climate change. On the basis of non-competitive input-output models, this article sets up a relationship model about CO2 emissions of anthrop industrial activities between two regions in the way of decomposing the economic activities into exporting, importing, consumption and investment. Then the authors calculates the CO2 emissions induced by consumption, investment, export and import of China respectively. The conclusion is that the augment of export and the improper export structure are the main reason of rapid increase of gross CO2 emissions in China. Especially, after China entry into the WTO, the CO2 emissions induced by net export account for a quarter of Chinese gross CO2 emissions. So it is the efficient way as well as the key task to change the export structure, expedite the high energy-using industries international transfer, and promote the industrial technology and add-value of export products.
