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, ...
