The target of the developed Tiered approach is

by the CML (Guinée, 2002) or ReCiPe (Goedkoop et al., 2009) method). Furthermore, related databases have already been established, e.g. GaBi or ecoinvent (UNEP and SETAC, 2011).
In comparison, for SLCA several impact categories have been proposed (Benoit and Mazijn, 2009, Neugebauer et?al., 2014 and Weidema, 2006), but they PP242 are still under discussion, as related impact pathways are lacking and the focus has so far been on the representation of stakeholder groups without bridging the gap towards impact assessment (Neugebauer et al., 2014).
