  • Q A Why cement emissions matter for climate change

    A further 40 of cement emissions come from burning fossil fuels to heat kilns to the high temperatures needed for this calcination process. The last 10 of emissions come from fuels needed to mine and transport the raw materials. Therefore cement emissions depend largely on the proportion of clinker used in each tonne of cement.

  • Improving cement grinding GCP Applied Technologies

    The majority of CO 2 produced during cement manufacture arises during clinker production due to the calcination of calcium carbonate fossil fuel burning and electricity consumption (mostly for grinding). Using a base CO 2 factor of 862kg CO 2 /t clinker each one percent drop in clinker in cement can reduce emitted CO 2 by 8-9kg/t cement.
