  • 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.

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
