Cement - EPA

GHG emissions from cement manufacturing are CO2 emissions from clinker production. There are no CO2 emissions from the finish grinding process, during which clinker is ground finely with gypsum and other materials to produce cement. However, CO2 emissions are associated with the electric power consumed by plant.
