Abstract

Life cycle assessment studies (LCA) accordingto ISO 14040 and ISO 14044 andusing generic data (i.e. without regard forgeographic variability in the life cycle inventory<LCI> or life cycle impact assessment<LCIA>) are well adapted to evaluate environmentalimpacts from a global perspective.For impact categories that are notglobal in nature such as acidification, eutrophication,or toxicity, the use of genericdata can lead to results that do not reflectthe impacts accordingly. Clearly, the needfor spatial differentiation depends on thescope and boundaries of the study. However,when assessing LCIs from differentregions, or when geographical conditionsof the emission location are known, regionalizationmight increase the discriminatingpower of LCIA. Future research should befocused on developing guidelines identifyingwhen spatial differentiation is relevant,what type of differentiation is needed, andon generating and linking compatible LCIand LCIA that are both geographically specificto continents (for political reasons thisis more accepted) and situation dependentto better reflect local variations.
