A group-model development method for LCA is built that permits one to know the choice makers' psychological types and values within the stock research on a case- and situation-specific foundation. merely by way of this, LCA effects becomes suitable in a decision-making process.

Two case reports at the modelling of recycling and different end-of-life concepts of aluminium home windows and beech wooden railway sleepers in LCA supplement the methodological part.

Marketing and lobbying, are secondary but nonetheless frequent uses of LCA-results (see also Chap. 2). Furthermore, LCA-results can be used as a basis for environmental labelling82. , the selection of a product, the selection of a supplier for the same product as procurement decisions, or the evaluation of different design options. In all these decision situations, the environmental criterion is only one among many. The financial leeway is one of the further criteria common to all decision situations mentioned84.

These in- and outputs should include the use of resources and releases to air, water and land associated with the system. The summary of the environmental interventions of a product over its life cycle is called the life cycle inventory (LCI). Step 3: Life Cycle Impact Assessment evaluates the inventoried in- and outputs with regard to their environmental implication. Several steps can be distinguished within the assessment: the classification (the assigning of inventory data to impact categories), the characterisation (the weighting of the assigned inventory data within impact categories) and the valuation (the aggregation of the impact categories by normalisation and addition).

1996:56). This kind of systematic error is concerned with if processes held relevant for the environmental impacts of a product are considered at all. This book postulates a second source of systematic error related to the setting of system boundaries (as final defining element of an input-output model) in the life cycle inventory analysis: the reductionistic way of modelling in the life cycle inventory analysis resulting in an input-output model and the representativeness and adequacy (validity) of the model in view of the characteristics of the real material and energy flows of the socio-economic system.
