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.
