Cement production emits carbon through the burning of fossil fuels to heat kilns (40% of emissions) and the chemical process of turning limestone and clay into cement using that heat (60% of emissions). Electrifying production facilities and making them more energy efficient can help decarbonize the former but not the latter, which …

The Cement Manufacturing Process. The production of cement involves a series of steps that transform raw materials into the final product. The process begins with the crushing and grinding of raw materials, followed by the formation of clinker, and concludes with the grinding and mixing of clinker to produce cement.

The cement production process. Cement production is energy intensive, requiring 3.3 Gigajoules of thermal energy per ton of clinker - so another source of carbon in the industry is the way plants are powered. Instead of using carbon-intensive fossil fuels, manufacturers could use carbon-neutral biomasses.

CDIAC's method for estimating process emissions from cement production by country is taken from a report by Griffin (1987) and requires that cement production data in tonnes are multiplied by a fixed factor 0.136 to obtain tonnes of carbon emitted as CO 2, i.e. 1 t of cement produced results in 0.136 × 3.667 = 0.50 t CO 2 (Boden et al., 1995).
