The cement industry is a major contributor to carbon emissions, responsible for 5–8% of global emissions. This industry is expanding, particularly in emerging economies, and it is expected that CO2 emissions will rise by 4% by 2050. To address this critical concern, this paper identifies ten factors that contribute to carbon emissions in …

Carbonation occurs gradually in concrete as CO 2 in the air reacts with cement to form water and calcium carbonate. A 2016 paper in Nature Geoscience found that since 1930, carbonation in concrete has offset 43 percent of the emissions from the chemical transformation of calcium carbonate to clinker during cement production.
