Abstract:

We have to take consideration of spatial transfer in responsibility division and pollution control of regional carbon emissions to develop a fair and workable scheme for emission reduction and governance. There are different industrial structures and consumption patterns among different regions in China, and there are frequent regional trade, so the embodied carbon emissions and pollution emissions in trade need to be estimated. Using multi regional input-output model, we calculated carbon emissions and SO2 emissions in Jiangsu Province from the perspective of producers and consumers, respectively. In the view of producer, Jiangsu’s carbon emissions and SO2 emissions are 101.07 Mt C and 1.155 0 million tons, respectively. From the view of consumers, the carbon emissions and SO2 emissions in Jiangsu are 118.94 Mt C and 1.245 5 million tons, respectively. The results showed that Jiangsu is a net carbon emission and net SO2 absorption area, that the net carbon emission is 17.87 Mt C and the net SO2 absorption is 90 500 tons. The embodied carbon emissions and SO2 emissions in each sector are estimated as well. The sources in the top four sectors of embodied carbon emissions and SO2 emissions and the sources of carbon emissions and SO2 emissions in the final demands are analyzed. The embodied carbon emissions and SO2 emissions in metal smelting and rolling processing industry, chemical industry, electric power and heat production and supply industry and construction industry occupy more than half of Jiangsu’s total embodied carbon emissions and SO2 emissions. The embodied carbon emissions and SO2 emissions in metal smelting and rolling processing industry mostly come from Hebei, Shanxi, Henan and Gansu. The embodied carbon emissions of chemical industry are mainly from Liaoning, Xinjiang and Shanxi, the embodied SO2 emissions come from Henan, Shanxi, Liaoning, Xinjiang. In electric power and heat production and supply industry, the embodied carbon emissions of electric power and heat production and supply industry are mainly from Anhui, Shanxi, Liaoning and Henan, and the embodied SO2 emissions mostly come from Henan, Shanxi and Liaoning. In construction industry, the embodied carbon emissions are mainly from Hebei, Henan and Anhui, and the embodied SO2 emissions mostly come from Henan, Shandong and Hebei. Jiangsu faces great pressure of industrial structure adjustment in the future.

Key words: embodied carbon emissions, embodied SO2 emissions, multi regional input-output model
