%X The comparison of domestic and international calculation methods of CO2 emission from cement production has important reference value for establishing national calculation standards of CO2 emission from cement production. At present, international organizations like Intergovernmental Panel on Climate Change(IPCC)and World Business Council for Sustainable Development (WDCSD) have promulgated a series of universally applicable methods, and a number of developed countries have also proposed their own calculation systems. In this paper, we first briefly introduced the domestic and international calculation methods of CO2 emission from cement production, and performed a comparison of these methods from four aspects, including operational boundaries, raw material calcination emissions, fuel combustion emissions and indirect emissions. Then we made a discussion about the accuracy and applicability of those methods. The conclusions are as follows: 1) Those systems are approximately same in the framework of calculation process, but there are differences in operational boundaries, calculating methods and CO2 emission factors; 2) WBCSD-Cement Sustainability Initiative provides the methods of setting operational boundaries for countries or enterprises to choose the scope of accounting and reporting; 3) On plant level, calcination CO2 can be calculated in two ways: based on the quantity and composition of the raw mix consumed or based on the clinker produced plus discarded dust. The two approaches are, in theory, equivalent. On country level, the latter approach is usually adopted; 4) CO2 from fossil kiln fuels (coal, fuel oil and natural gas) is calculated based on fuel consumption, net calorific values, and CO2 emission factors. For China, low calorific value is applicable; 5) On country level, the emissions of external production of electricity consumption should be included in the gross emissions, while indirect emission savings such as heat and power exports should be subtracted from the total. On the basis of the above, we finally put forward the primary calculation process for establishing national CO2 emission factor system of cement production, and then discuss the further research direction. The research results are hopeful to provide a scientific basis for compiling national greenhouse gas inventory of cement production and calculating CO2 emissions of different provinces in China.
