Abstract: Greenhouse gas (GHG) emissions from Chinese thermal power industry were calculated according to the sectoral method from fixed source combustion emissions of the “IPCC Guidelines for National Greenhouse Gas Inventories”. Thermal power industry emission factors and activity data from 2007 were used. Both the measurement of emission factors and subsequent data manipulations complied with the requirements of IPCC quality assurance (QA) and quality control (QC) for the calculation of GHG emissions. Results showed that CO₂ and N₂O emissions from thermal power industry in 2007 were 2.81×10⁹ and 1.56×10⁵ t , respectively. A comparison was made between the estimated emissions using the sectoral method and the reference method, which used national statistical data to directly calculate CO₂ emission from thermal power industry. The results showed relative deviations of 7.5%, 98.8% and 1.6% respectively for coal, oil and natural gas combustion. Thus, the CO₂ emission estimates for coal and natural gas combustion were not much different from these two approaches, though oil was an exception.
