LCA-kompatibla biodiversitetsmetoder för vindkraftsproduktion (Swedish)
Abstract [en]

Life Cycle Assessment (LCA) is a widely used method to assess the environmental impacts of a products entire value-chain. However, LCA currently falls short in incorporating biodiversity impacts. This study aims to evaluate different biodiversity assessment methods in regards to what biodiversity aspects they can address, how compatible the methods are with LCA, as well as how relevant they are for wind power production during use-phase. A literature review identified three different methods: InVEST Habitat Quality Model, Landscape Assessment Protocol and Species Distribution Modeling, which were then selected for further evaluation. The criteria-based evaluation shows that the three methods address multiple aspects of biodiversity, including those not addressed in contemporary LCA methods. Furthermore, the evaluation reveals a number of challenges in regards to their compatibility with the LCA-framework. To conclude, this study reveals that finding biodiversity assessment methods that can be incorporated into LCA is difficult without changing the format of how the results from the method is presented.

Abstract [sv]

Livscykelanalys (LCA) är ett verktyg som används för att bedöma den miljöpåverkan en produkt har genom hela produktkedjan. I dagsläget finns det brister i hur LCA bedömer vissa aspekter av biodiversitet. Bland annat har LCA idag inte möjlighet att bedöma alla av de fem direkta faktorerna som leder till förlust av biologisk mångfald. Denna studie syftar till att utvärdera olika metoder som bedömer biodiversitet med hänsyn till vilka aspekter av biodiversitet de kan bedöma, hur väl de kan integreras i LCA, samt hur relevanta de är för bedömning av vindkraftens påverkan på biodiversitet under användarfasen. Genom en litteraturstudie identifierades tre metoder som valdes ut för vidare utvärdering, nämligen InVEST Habitat Quality Model, Landscape Assessment Protocol och Species Distribution Modeling. En lista med 14 kriterier skapades för att utvärdera metoderna. Dessa kriterier lyfter vilka aspekter av biodiversitet metoderna kan bedöma, huruvida de är kompatibla med ramverket för LCA, samt vilka styrkor eller brister de besitter utifrån ett metodiskt perspektiv. Utvärderingen visade att metoderna kan bedöma flera aspekter av biodiversitet som inte tas upp i redan etablerade LCA-metoder. Utvärderingen synliggjorde även flera utmaningar i metodernas kompatibilitet med ramverket för LCA. Sammanfattningsvis visar denna studie att det är en utmaning att hitta metoder som bedömer biodiversitet och som även kan integreras i LCA utan att det krävs förändringar i hur resultaten presenteras.
