Abstract

Until now, impact assessment within LCA has mainly focussed on the substance hazard for some impacts, whereas, for other impacts, substance fate is included in the assessment as well. The main goal of this paper is to define the position of fate modelling in LCIA, and to specify the requirements for a general LCA fate model. A proposal is made to clearly distinguish an impact-category independent fate analysis from a separate exposure analysis and an impact-category related impact analysis, and to use a global multimedia model as a modelling basis. This modelling basis might be supplemented with substance-specific models for a number of substances.
