QA 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.
