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.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
