The impact categories considered in this study were: global warming for a time horizon
of 100 years (GW), acidification (A), eutrophication (E), non-renewable resource
depletion (NRRD) and photochemical oxidant formation (POF). The selection of these
categories was conditioned by the parameters available from the inventory analysis.
The inventory parameters assigned to each impact category and the sources of the
characterisation factors that allow the aggregation of the parameters within each
category,
