Abstract

This report has been prepared by the SETAC Europe Scientific Task Group on Global And RegionaL Impact Categories (SETAC-Europe/STG-GARLIC) that is installed by the 2nd SETAC Europe working group on life cycle impact assessment (WIA-2). This document is background to a chapter written by the same authors under the title "Climate change, stratospheric ozone depletion, photo-oxidant formation, acidification and eutrophication" in Udo de Haes et al. (2002) . The chapter summarises the work of the STG-GARLIC and aims to give a state-of-the-art review of the best available practice(s) regarding category indicators and lists of concomitant characterisation factors for climate change, stratospheric ozone depletion, photo-oxidant formation, acidification, and aquatic and terrestrial eutrophication. Backgrounds on a selection of general issues relevant in relation to LCA and characterisation of impact in LCA are given in another background report from Potting and Klvpffer (2001) .
