SDGs are now being used by some corporations in formulating and expressing business strategies. However, assessing the effects of corporate activities and products regarding their contribution to SDGs is difficult. In this paper, we have developed a method for linking life cycle sustainability assessment (LCSA) with the SDGs and calculating the contribution to SDG achievement. An essential part of this approach is the weighting of LCSA impact categories, which is typically done using equal weighting. This weighting method enables compensation of negative contributions by positive contributions in different impact categories but results in ambiguity in the results. This article identifies alternative weighting methods, integrates them into a computational approach, and determines their influence on the SDG contribution scores. The analysis shows that the use of alternative weights changes SDG contribution scores. However, the same product always has the highest SDG contribution score, regardless of the weighting method used. Nonetheless, the recommendations for action with regard to the total product alternatives would change depending on the weighting method.en2212-82712023618623Elsevierhttps://creativecommons.org/licenses/by-nc-nd/4.0/Sustainable development goals (SDGs)SDG quantificationSustainable developmentLife cycle sustainability assessmentTechnikIngenieurwissenschaftenJournal Article10.15480/882.511410.1016/j.procir.2023.02.10410.15480/882.5114Journal Article
