SCRIVENER No, of course not. For one thing, concrete is a low CO 2 material. The intrinsic CO 2 content per ton for concrete is ten times lower than that of steel or bricks and one hundred times lower than that of plastic. Yes, cement is carbon-intensive. But cement is just a small component in the final concrete

Limestone calcined clay cement as a low-carbon solution to

1. Introduction. Concrete production has an impact on the climate as it accounts for 5–8% of total anthropogenic CO 2 emissions . 95% of this CO 2 is produced during the fabrication of cement, half of it being released by the decarbonation of the limestone during cement fabrication. Cement is, after power generation, the second largest source of anthropogenic CO 2 emissions , and also the

A new, greener cement to meet future demand - EPFL

Applied globally, it could help bring down future global CO2 emissions by several percent. Substituting a fraction of the Portland cement used to make concrete is a well-established way to cut emissions – understandably so, considering that the production of each ton of cement releases up to 800kg of CO2.
