In an environmental existence cycle review of goods (LCA), an unambiguous, scientifically established, ‘objective’ attribution of fabric and effort flows to a product is natural fiction. this is often as a result primary epistemological stipulations of LCA as a modelling approach below the complexity of our socio-economic process. as an alternative, numerous psychological versions and values advisor this attribution. This results in a sensible version in a particular selection situation.

This booklet indicates for the 1st time how psychological versions and values impact this attribution within the existence cycle stock step of LCA. one of many key findings is that different administration ideas for a sustainable use of fabrics has to be taken into consideration for the attribution of fabric and effort flows to a product. differently, development concepts steered by means of an LCA may well prove to even irritate the environmental state of affairs if reassessed from a meta-perspective.

As a end result of this e-book, the declare of unambiguitiy (‘objectivity’) of the lifestyles cycle stock needs to be deserted. A group-model construction approach for LCA is built that permits one to understand the choice makers' psychological types and values within the stock research on a case- and situation-specific foundation. purely by means of this, LCA effects becomes suitable in a decision-making process.

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

This ebook is a ‘must have’ for researchers, specialists and practitioners within the fields of decision-oriented lifestyles cycle evaluate in addition to product-related environmental administration, modelling and decision-making.

Example text

He takes the shaking of a garden table to illustrate how different scientific disciplines develop different problem descriptions. These problem descriptions lead to totally different creative models for the solution of the problem. 4 Impossibility to validate LCA-models In a decision situation, several action alternatives are compared. The selected alternative can be understood as creative model for real world interventions. The implementation of the creative model puts the selected alternative into practice, creating ‘reality’.

Pohl et al. “ (Pohl et al. 1996:54). They refer to a first type of systematic error in the life cycle inventory analysis when they write: “Systematic errors occur when relevant processes are excluded and the model structure is therefore incomplete. For example the question of 76 see Ulrich 1981:8f; Keeney and Raiffa 1976:11 LCA as method and its modelling characteristics 39 whether one-way bottles or deposit bottles are less polluting cannot be answered without considering transport” (Pohl et al.

The need to make assumptions on the organisational principle in descriptive LCA becomes visible when, for instance, joint coproduction processes have to be allocated70; furthermore, if improvement options determined by descriptive LCA have to be considered against material and market characteristics, if re-evaluated from a meta-perspective (see Chap. 3). The assumption concerning the organisational principle as determinant of the behaviour of the socio-economic system made implicitly or explicitly during the development of the product system must also be seen as an element of complexity reduction.
