Abstract

Many impact assessment methods use weighing factors to agregate the different environmental effects into a single score value for the total impact caused by a product life cycle. The introduction of subjectivity in the decision process during product development, by using this kind of weighting factors, should be avoided. A more objective approach uses indicators based on laws of physics, for example the notion exergy. Construction and implementation in Simapro of an exergetic indicator is illustrated in this paper.
