Abstract [en]

This study is primary divided into two parts; updating the existing Exotax98 (monetaryvaluation method) including the characterisation methods to an update named Ecotax02, andapplying it on a case study. Updating Ecotax98 to Ecotax02 includes a revision of the taxesfrom which Ecotax98 is based on, and recalculation of the weighting factors and the weight ofreference values. Among the advantages of using weighting methods in general is the abilityto aggregate impact categories and to compare them individually. This is done in the casestudy part.

The case study also shows that this ability is important and that leads us to see what kind ofinterventions that matters the most with different weighting methods and that Ecotax02 didput some substances in focus that was less prioritised in the other methods and vice versa.

Abstract [sv]

Denna studie är huvudsakligen uppdelad i två delar. Den första delen är uppdatering avexisterande Ecotax98 metoden (monetär viktningsmetod), uppdateringen omfattar ävenkaraktäriseringsmetoderna som hör till Ecotax. Den andra delen består i att utvärdera metodenpå en fallstudie. I uppdateringen av Ecotax98 till Ecotax02 ingår revidering av miljöskatteroch miljöavgifter som metoden baseras på. Bland de fördelar som hör till metoden ärmöjligheten att kunna aggregera olika effektkategorier och sedan jämföra dessa sinsemellan.Detta utförs i fallstudien.

Fallstudien påvisar också att aggregering av effektkategorier är viktigt för att utröna vilkaämnen eller emissioner som betyder mest för resultatet för de olika viktningsmetoderna.Ecotax02 metoden visade sig prioritera många andra ämnen eller emissioner gentemot deandra i studien jämförda viktningsmetoderna och vice versa.
