Inventory and input-output analysis of CO2 emissions by fossil fuel consumption in Beijing 2007

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 + 07 t, 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 (3.12 t/1E + 4 Yuan) is 0.65 times larger than that of primary industries (1.89 t/1E + 4 Yuan) and 1.58 times larger than that of tertiary industries (1.21 t/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 + 08 t, respectively. Results of this study provide a sound scientific database for effective policy making in Beijing to reduce CO2 emissions. (C) 2012 Elsevier B.V. All rights reserved.
