To Lyon tower, France Low-carbon concrete Mix used: engineered concrete with CEM I (50%) + slag (50%) + limestone filler

Cement is responsible for 85% of concrete’s CO2 emissions ​although it only accounts for 12% of its composition​. Clinker, its main constituent (produced by firing limestone and clay), ​is responsible for cement’s high carbon footprint due to:

– Heating of cement plant ​ furnaces to 1500°C (1/3)

– ​The chemical reaction that releases carbon during firing (2/3)

Where do concrete’s CO2 emissions come from?
