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