Fig. 10. Sensitivity analysis for aggregate LCA impact for Cases 4–8T. Parameters are listed
in Table 3 and changes that incurred less favorable results (compared to the base cases) are indicated with a (−) sign for each case and parameters that incurred more favorable results (compared to the base cases) are indicated with (+) signs for each case. Parameters that do not impact the LCA impacts are not shown. The Impact 2002+ method only accommodates non-renewable resource impacts, and thus the aggregate LCA impact for total resources cannot be determined.
