摘要: The simplification of life cycle inventories (LCIs) by reducing the number elementary flows is a major issue regarding their use in sector-specific applications. It can ease understanding complete LCIs and focus on most relevant flows. Current that have been created for Environmental Product Declarations (EPDs) differ from databases provided academics, which more than thousand are considered, as they contain reduced list substances. In this paper, we examine consequences these simplified accuracy impact assessment (LCIA) step. We consider specific case an LCI database building products was developed France. Three environmental midpoint endpoint indicators analysed: global warming potential (GWP), photochemical ozone formation (POCP), disability-adjusted years (DALY). results 110 materials indicate not always relevant, large uncertainties were detected final results, especially describing creation damage to human health require larger GWP indicator, approximately 95% materials. analysis key each indicator enables identification missing LCI. Perspectives recommendations improve level details according methods.
