Streamlined LCA

z Limitations in terms of:y timey costy datay analytical approach

z 80% of environmental impacts are decided at the product design phase

z Streamlining the LCA process

Streamlined LCA

z Screen with inviolates list: activities or choices that are obviously incorrect from an environmental standpoint

z Limit or eliminate components or processes of minor importance

z Limit or eliminate life-cycle stagesz Include only selected environ. impactsz Include only selected inventory parameters

4

Streamlined LCA

z Limit consideration to constituents above threshold weight or volume

z Limit or eliminate impact analysisz Use qualitative rather than quantitative

informationz Use surrogate data

Streamlined LCA

Develop a rating for each element in the matrix.For Graedel, 0 = very high impact, 4 = very low impact

Example: Automobiles

z Comparison between the automobile in 1950 vs. 1990

z Evaluate impacts during various stagesz In addition to air emissions:

y tiresy oils, brake fluid, hydraulic steering fluidy hoses, batteries, ...
