Purpose: Circular business models have a huge potential to lead to economic, social and environmental benefits. But in order to archive this it is crucial to reach global implementation. Therefore, the purpose of this paper is to investigate how firms can assess the potential and criteria for implementing circular business models in different global markets.

Design/Methodology/Approach: To reach the stated purpose, we have adopted a quantitative research approach and undertaken 25 explorative interviews in three large Swedish manufacturing companies and their global service network.

Findings: In this paper, a decision support tool to choose the appropriate circular business model for global implementation has been developed that facilitates the first steps towards circular business models implementation. It identifies eleven criteria that should be analysed to decide the appropriate circular business model.

Originality/Value: Circular business models have not yet reached wide implementation. One reason is that they are often presented as one fits all solutions but this is not appropriate for global implementation. Therefore, the decision tree that is developed in this paper helps companies to choose the circular business model that is most appropriate for a specific product in a specific market.
