Global decarbonization potential of CO₂ mineralization in concrete materials.

ABSTRACT: CO₂ mineralization products are often heralded as having outstanding potentials to reduce CO₂-eq. emissions. However, these claims are generally undermined by incomplete consideration of the life cycle climate change impacts, material properties, supply and demand constraints, and economic viability of CO₂ mineralization products. We investigate these factors in detail for ten concrete-related CO₂ mineralization products to quantify their individual and global CO₂-eq. emissions reduction potentials. Our results show that in 2020, 3.9 Gt of carbonatable solid materials were generated globally, with the dominant material being end-of-life cement paste in concrete and mortar (1.4 Gt y^-1). All ten of the CO₂ mineraliz
