Fig. 1 LCI decomposition by final-stage inputs, using cement as an example for a product that is used in the final stage of producing the product for which an LCI is undertaken
Fig. 2 LCI decomposition by origin, using the process of producing cement as an example for the ultimate origin of impacts from one particular process
Fig. 3 Integrated coefficient matrix (I − AIH) of integrated hybrid LCA (blue-shaded areas include nonzero values, but may be sparsely populated; non-shaded areas contain zeroes; gray-shaded areas represent 1s on the diagonal; pu physical units; mu monetary units)
Fig. 4 Example transaction matrix with eight processes, three industries and five product sectors with extensions for greenhouse gas emissions (upstream and downstream cut-off matrices are shaded in green and orange, respectively)
