摘要：Abstract. Global production of cement has grown very rapidly inrecent years, and, after fossil fuels and land-use change, it is thethird-largest source of anthropogenic emissions of carbon dioxide. Theavailability of the required data for estimating emissions from globalcement production is poor, and it has been recognised that some globalestimates are significantly inflated. This article assembles a large varietyof available datasets, prioritising official data and emission factors,including estimates submitted to the UN FrameworkConvention on Climate Change (UNFCCC), plus new estimates for China andIndia, to present a new analysis of global process emissions from cementproduction. Global process emissions in 2018 were 1.50±0.12 Gt CO2, equivalent to about 4 % of emissions from fossil fuels.Cumulative emissions from 1928 to 2018 were 38.3±2.4 Gt CO2,71 % of which have occurred since 1990.
