Short summary
This study provides an accurate bottom-up quantification of cement carbonation sinks at national and global levels. It shows that the global CO2 uptake by cement materials increased from 7.74 Mt yr-1 in 1928 to 0.84 Gt yr-1 in 2023; for 2024, this value is projected to be 0.86 Gt yr-1. The accumulated CO2 uptake offsets about 46 % of cement process emissions. Dominance with respect to cement carbon uptake has shifted from the USA, Japan, and some European countries to emerging economies such as China and India.
