Success Factors and Challenges of the Climate Bonus Flensburg: A Real-World Lab Analysis

Abstract

This paper presents the findings of an investigation into the Climate Bonus Flensburg (CBF), a regional complementary currency designed to promote sustainable climate action in the Flensburg region of Germany. The study identifies critical success factors and challenges by analysing the CBF's first year through a comprehensive real-world laboratory approach and offers recommendations for future success. Using a transdisciplinary mixed-method approach, internal insights from the project coordinator were combined with a SWOT analysis based on feedback from 10 external cooperation partners. A comprehensive examination of both internal and external perspectives revealed significant commonalities and differences, which are essential for guiding management in making strategic decisions within a resource-limited environment, particularly as the primary funding period ends in March 2026. To capitalize on the success factors and surmount the challenges, it is recommended that key strategies be implemented. These include improved communication and collaboration through the utilization of workshops, clearer messaging, action plans and the use of KPIs to strengthen the complementary currency system (CCS), enhanced stakeholder ownership through joint decision-making, and established transparent participation criteria to mitigate greenwashing risks. The findings highlight the CBF’s crucial role in stimulating regional economic activity, building social capital, and driving ecological transformation. Nevertheless, ensuring long-term financial sustainability and expanding monetary flows will be pivotal for the CBF's success beyond 2026.
