Emissions from the Cement Industry 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.
