| Abstract: | Life Cycle Impact Assessment (LCIA) results are typically reported as individual scores, or as a breakdown of the most direct inputs; either as absolute values or relative scores. It is proposed to report not only the direct or primary LCIA scores, but also the impacts from secondary and tertiary processes. A graphical technique to report LCIA results is described where a combination of pie and donut charts, with the inner most layer representing direct impacts and subsequent outer layers representing preceding indirect impacts, is presented. An MS-EXCEL spread sheet is presented where the methods and outcomes are shown. This can then be used to display LCIA results. It is possible to present both primary and indirect impacts in a single figure. Significant indirect impacts contributing to the total score of an LCA are clearly visible. |
