Fig. 2: Key environmental impact results of cement manufacturing in China.
From: Modernizing cement manufacturing in China leads to substantial environmental gains

a compares the key environmental impacts of cement manufacturing based on three major CMTs. The bubble size represents the share of the selected impact category accounting for the sum of one CMT’s LCA normalization results. b shows the geographical location of two selected cases at the provincial level. c illustrates the evolution of the PMF environmental impact caused by cement manufacturing based on three cement kilns in 2002, 2006, 2010, 2014, and 2018.
