Environmental Indicators & Engineering: an alternative for weighting factors
نویسندگان
چکیده
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.

متن کاملA Monetary Valuation Weighting Method for Life Cycle Assessment Based on Environmental Taxes and Fees
Weighting in life cycle assessment (LCA) is a controversial subject due to its dependence upon value judgements. One of the issues that has to be dealt with is whose values that shall be reflected. In a democratic society, a fair candidate to put forward would be the government. In environmental economics taxes and fees set up by governments to protect natural resources and the environment are ...
