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.

More sustainability for the cement industry
Clinker is the most important component in making cement a hydraulic binder. For years, cement manufacturers have been striving to reduce the so-called clinker factor – the proportion of clinker in cement – by adding additives. This is because the higher the proportion of clinker, the more CO 2 is released during cement production.
