Cement Emissions. The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.
The cement production process consumes a lot of energy. According to some estimates, the cement industry contributes as much as 5% of total global CO 2 emissions (Gartner Citation 2004). The cement industry has several sources of CO 2 emissions, including fuel combustion and calcination.
