Abstract: | Background, aim, and scope Life cycle assessment (LCA) has traditionally been considered a site-independent tool, but nowadays, there is a trend towards
making LCA more site-dependent. Site-dependent characterization factors have been calculated for regional impact categories
such as acidification, terrestrial and aquatic eutrophication, and smog. Specifically, for aquatic eutrophication, characterization
factors have been proposed for large geographical areas (mainly European and North American countries). Those factors are
not detailed enough for countries which present large geographical, climatic, and economical variability such as Spain. Therefore,
this work aims to calculate the characterization factors and the normalization reference for aquatic eutrophication at a regional
level, using Galicia (NW Spain), a region with increasing problems of eutrophication, as a case study. Finally, the comparison
of the factors obtained here with literature values will be used to analyze the influence of spatial differentiation with
increasing coverage of the causality chain. |
