Cement sector CO2 emissions double in 20 years

World: The total volume of CO2 emissions released during cement production have more than doubled over the past 20 years, a study has revealed. In 2021 CO2 emissions from the manufacture of cement came to 2.6Bnt, more than 7% of all emissions, according to Robbie Andrew, a greenhouse gas emissions scientist at the CICERO Center for Climate Research in Norway and the Global Carbon Project. In 2001 the CO2 emissions from cement production were just 1.2Bnt.

Driven by China, the global cement sector’s CO2 emissions have now more than tripled in the 30 years since 1992, recently increasing by 2.6% a year. The drivers are not just that more cement is being made, but that the CO2 intensity of production has risen by 9.2% per tonne, according to the International Energy Agency. This is due to a switch from production in mature markets to developing ones, with China again a dominant factor.
