Organisations as well as for strategic decisions of companies, where the relative economic size of the object of investigation The consequential approach is of relevance for policy support of governments and international The decisional approach is sensible for LCAs of product and processĭevelopment, as well as site and supplier evaluation carried out by private companies in case the relative economic size of Results and discussionThe attributional approach is sensible for environmental reporting and product labelling and declaration where the relativeĮconomic size of the object of investigation is small. Three groups to which the most appropriate LCI models are assigned. We recommend using the relative economic size to classify objects of investigation and the LCA goals related to them into The key question is how to distinguish between small, medium and large consequences. Under the conditions of mutatis mutandis (the necessary changes being made). Decision situations with medium to large potential consequences should be modelled Main featuresIndividual decision with comparatively small consequences can be modelled under ceteris paribus (other things being equal) conditions. Use and supply within the international operations of an environmental service company with headquarters in France. The framework is applied to a case study of an LCA of electricity This paper proposes criteria that help to classify typical LCA questions regarding real business cases andįind the most appropriate life cycle inventory (LCI) model. Three basically different models exist in life cycle inventory analysis: the attributional, the consequential and theĭecisional model. Time, it is often used as an illustrative example to highlight the modelling differences between decision-oriented and descriptive Background, aim and scopeElectricity use or substitution is one of the key parameters with regard to life cycle assessment (LCA) results.
