%X The cement industry is a major source of greenhouse gas-carbon dioxide (CO2) emission. According to the principles and characteristics of cement production technique, the mathematical model is established for calculating CO2 emission in cement industry from 2001 to 2010 with the emission factors of production processes and energy consumption. The results indicated that the CO2 emissions increase rapidly every year in China, with a linear relationship between the CO2 emissions and the cement outputs, the comprehensive energy and resource consumption per unit cement product. The raw processing and fuel burning accounts for about 49% and 51% in total CO2 emission of cement industry, respectively. The CO2 emission decreases from 0.69 t·t-1 in the "10th Five-year" plan to 0.65 t·t-1 in the "11th Five-year" plan. The CO2 emissions per ten thousand Yuan GDP decreases to minimum 0.3054 t in 2008, corresponding to 10.69% reduction. The result shows clearly that the saving energy, resource recycling and increase economic efficiency can greatly reduce CO2 emissions.
