Cement emissions intensity has remained relatively stable since 2018, at just under 0.6 t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinker-to-cement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.

Cement Plants: Coke. Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel's volatiles are lost without ...

Arpita. 17 Apr. Bituminous coals make the best coke and are in any case the most common, and these are most often used in the cement industry, although steam coals are occasionally used. When burning a pulverised fuel, higher volatiles are preferred because they speed up ignition and allow a coarser grind to be used.
