Retail companies in Germany are increasingly exposed to climate-related risks but often lack the awareness and capacity to adapt effectively. This case study aims to support adaptation in the business sector. It shows how the largest retail association in Germany (Handelsverband Deutschland e.V., HDE) has developed tools, guidance, and trainings, specifically tailored to the needs of small and medium retail businesses. They should help enhancing resilience towards climate-related impacts such as supply chain disruptions, physical damage to buildings, and shifts in consumer behaviour.
