Abstract: According to non-competitive input-output tables, this paper re-calculates implied carbon dioxide emissions in exports of various industries in the period of 2002 to 2011 on the basis of removing decreased energy and carbon emissions of imported intermediate inputs. The results indicate that the total emission of carbon dioxide embodied in Chinese exports is lower than the estimations of documents of the same kind; furthermore, the proportion of implied export carbon emissions in some industries with high intensity of carbon emissions is not high; on the contrary, some industries with low intensity of carbon emissions have a comparative high proportion. The paper contends that the contrast is mainly caused by the difference of export scale in various industries. Therefore, in order to reduce the implied carbon emissions in exports, we should not only encourage the research and development of energy-saving and clean energy technology, and reduce the intensity of energy consumption and carbon emission in industries, but also cut down the production capacity and export scale of industries with high energy consumption and emission step by step, and optimize the export structure continually.
