With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world’s most widely used material for construction from bridges to large buildings, 网页2021年12月16日 The construction ecosystem accounts for about 25 percent of global greenhouse-gas emissions (GHG). Concrete—specifically, the cement from which it is made—is the largest contributor, accounting for 4.5 percent of global GHG emissions and 7.0 percent of CO₂ emissions in 2019. 1 Ali Hasanbeigi, “Global cement industry’s GHG 网页2023年3月6日 With a growing number of industries and sectors moving toward net-zero emissions, a significant amount of value is at stake in cement.
