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.
