Weighting is often used in environmental systems analysis tools. One
method is Ecovalue which in its first version was published in 2011. In this
paper an updated version is presented. New factors are for exotoxicological
impacts and for particulates. The factor for climate change has been
updated. The updated set of valuation weighting factors also includes
default values in addition to low and high values. The new set is matched
with the Recipe methodology except for abiotic resources where
Cumulatative Exergy Demand is used. Results from an ICT product show
that in this case climate change, toxic impacts and resources use are
highlighted as important impact categories.
