Abstract: The objective is to know how the CO2 emits and how much the CO2 emits due to the cement manufacture in both direct and indirect ways with the increasing concerns about the global warming and the cement plants emitting huge CO2. A precise method to calculate CO2 emissions including three processes was established in this paper and a case study was provided. From the case of 23 typical plants in China, we can see the amount of CO2 emissions at the right level. The summary of CO2 emissions consists of emissions from raw materials, fuels and electricity. The average result of the 23 typical plants is 0.74 t CO2 per ton clinker in this study. Therefore, CO2 emissions from these typical cement plants were pictured and then measured. The creative point is that an approach provides a basic framework to identify various situations in different cement plants in China and other in the rest of the world. The framework would be useful in quantitatively evaluating CO2 emissions for government to know precisely CO2 emissions in the cement plants.

Key words: carbon dioxide emissions| greenhouse gas| cement manufacture| coal combustion
