average LCI of US portland cement production. The LCI is assembled with data shared by PCA members through a survey process carried out in 2015 and represents 2014 operations. In 2014, the US cement industry generated 77,734,901 metric tonnes (85,688,036 tons) of portland cement (PCA 2015).
Depending on the particular grade of calcium carbonate, either t he plant processing and quarry operation stages of the products generally contribute the most to the cradle-to-gate life cycle impacts. This is mainly due to the high electricity use in the plant processing stage and the explosives used in the quarry operations stage.
