Cao, Zhi; Myers, Rupert J.; Lupton, Richard C.; Duan, Huabo; Sacchi, Romain; Zhou, Nan et al. (2020): The sponge effect and carbon emission mitigation potentials of the global cement cycle. In nature communications 11 (1), p. 3777. DOI: 10.1038/s41467-020-17583-w.
"Cement plays a dual role in the global carbon cycle like a sponge: its massive production contributes significantly to present-day global anthropogenic CO2 emissions, yet its hydrated products gradually reabsorb substantial amounts of atmospheric CO2 (carbonation) in the future. The role of this sponge effect along the cement cycle (including production, use, and demolition) in carbon emissions mitigation, however, remains hitherto unexplored. Here, we quantify the effects of demand- and supply-side mitigation measures considering this material-energy-emissions-uptake nexus, finding that climate goals would be imperiled if the growth of cement stocks continues."
