Cement CO2 Emissions

• Cement production is an important source of CO2 emissions, accounting for 1.8 Gt CO2 in 2005. Half of cement process CO2 emissions are due to the chemical reaction in cement clinker production. These process emissions are not affected by energy efficiency measures. Yet it might be possible to reduce clinker production by 300 Mt with more ...

Cement Production

Cement production is one of the largest industries in the world. Annual world production in 2013 was approximately 4 GT (of which, about half was in China). It is produced in kilns at around 1400o C (2500 o F), and approximately 750 kg (1650 lb) of CO 2 are released for each tonne (2205 lb.) that is made.

Cement – Analysis

Initial estimates suggest that 4.3 Gt of cement were produced globally in 2020. This is a modest increase from 4.2 Gt the previous year, driven in large part by infrastructure-related stimulus projects in China. China is the largest cement producer, accounting for about 55% of global production, followed by India at 8%.
