Abstract
With the most recent statistics available, a concrete emissions inventory is compiled for an input–output analysis to investigate the embodied CO2 emissions induced by fossil fuel combustion of Beijing economy in 2007. Results show that the total direct CO2 emissions amount to 9.45E+07t, within which 56.81% are released from coal combustion, 11.50% from coke combustion, 9.03% from kerosene combustion, 8.70% from natural gas and 6.40% from diesel, respectively. The average intensity of secondary industries (3.12t/1E+4 Yuan) is 0.65 times larger than that of primary industries (1.89t/1E+4 Yuan) and 1.58 times larger than that of tertiary industries (1.21t/1E+4 Yuan). The sector of Construction Industry contributes the largest share (21.98%) of CO2 emissions embodied in final demand for Beijing due to its considerable capital investment. Beijing is a net importer of embodied CO2 emissions with total import and export of 3.06E+08 and 2.00E+08t, respectively. Results of this study provide a sound scientific database for effective policy making in Beijing to reduce CO2 emissions.
