Impact assessment in SLCA: sorting the sLCIA methods according to their outcomes

摘要: Social Life Cycle Assessment (SLCA) is a tool assessing the social aspects of products and services. This article step forward from Guidelines wishes to clarify different impact assessment (IA) methods covered in how these would provide types information regarding product system. The outcomes resulting sLCIA are discussed through analysis three by for SLCA (UNEP 2009): Taskforce’s method, Hunkeler’s (2006) Weidema’s (2006). In order highlight outcomes, we analyze “nature” indicator results, sources stressors, way IA results linked Different provided depending on approach used. We stress that use pathways allows impacts. which compares state dimensions context system with international consensus, assesses “social performances.” Regarding needs look at other levels than unit process capture issues. Finally, two approaches used connect system: one carrying quantitative link between inventory functional all result pathways, other, weighting according relative importance an activity variable. features outcomes. Depending assessed. When stressors collected organizational level, e.g., country, sector, or enterprise, assessed becomes context, can be called “context units” parallel processes. SLCIA will also characterization models analysis: impacts versus performances. difference require further reflections. Two Guidelines. One uses Performance Reference Points allowing evaluation position dimension reference consensus. second one, closer LCA, derived technical nature processes, pathways. Choosing feasibility deriving variables broader set issues semiquantitative indicators ongoing issue requires research. Currently, choice informed availability indicators.
