CO2 Emissions Profile of the U.S. Cement Industry

CO2 Emissions Profile of the U.S. Cement Industry

cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production. In addition to combustion-related emissions, cement production also is a source of process-related emissions resulting from the release of CO2 during the calcination of limestone.
