(e.g. the Critical DilutionVolume, CDV – EU Ecolabel scheme)

• Case study designed to compare the USEtox models (1.01, 2.0) and theCDV approach in assessing the ecotoxicity impact of a virtual ‘down-the-drain’ product defined as an aqueous mixture of linear alkylbenzenesulfonate (LAS), benzisothiazolinone (BIT), alachlor, acetic acid, ethanol,acrylic acid and zinc sulphate

• Reduced model system used (only two life cycle stages, i.e. ‘upstream’and ‘downstream’ the production stage) to enable a focused study ofecotoxicity modelling.

• Major contribution (99.6%) of the downstream ‘disposal’ stage to thecharacterization factor (CF) calculated for the product (USEtox)

• Significant divergences between the absolute and relative downstreamCF (USEtox) and CDV calculated for the product and in-going substances,respectively

• LCA-based tools eventually more relevant to assess global impacts (e.g.greenhouse gas) than local impacts (e.g. ecotoxicity)?

• EU Product Environmental Footprint (PEF) project initiated in 2013-2016involving the first large-scale application of the USEtox model (consensusmodel for calculating (eco)toxicity impact scores in LCA – Rosenbaum etal., 2008) to a variety of in-market products
