Concrete construction "offsets around one half" of emissions caused by cement industry says IPCC

Around half of the carbon emissions from cement production are reabsorbed by the material when used in buildings and infrastructure, according to the latest IPCC climate report.
The "cement carbonation sink" absorbs an estimated 20 million tonnes of carbon every year, according to an overlooked section of the report published earlier this month ahead of the Cop26 climate conference.
"Direct CO2 emissions from carbonates in cement production are around four per cent of total fossil CO2 emissions,
