Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's mostconsumed resource.

Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions.

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.
