Emission to air/soil/water Multi-compartment fate modelling Emission to water Mono-compartment fate modelling Average sensitivity of species Acute-to-chronic factors Most sensitive trophic group Safety factors More than ten input parameters Two input parameters Comparison limited by result uncertainty Comparison possible • EU Product Environmental Footprint (PEF) project initiated in 2013-2016 involving the first large-scale application of the USEtox model (consensus model for calculating (eco)toxicity impact scores in LCA – Rosenbaum et al., 2008) to a variety of in-market products (e.g. before resource water depletion or climate change for laundry detergents) Aug Aug 2015 Apr Apr 2016 May May 2016 Nov Nov 2016 2017 Kickoff Work + Report SETAC Nantes SETAC Brussels Contribution to on-going discussion
