In the last decade, -resilience- has gained increasing recognition as a theoretical framework for understanding and managing change in complex social–ecological systems. Resilience assessments are increasingly used to inform sustainability initiatives, strategies, and policies. The Lewes Pound represents a new complementary currency model in the UK, aiming to build community resilience. However, there have been no empirical studies to date assessing the socio-economic impacts of this model. This article addresses the need to understand how such currencies function by measuring whether the Lewes Pound is capable of building resilience. This is done by developing a novel framework for estimating economic, social, and environmental outcomes, which uses a mixed-methods approach. Findings suggest that complementary currencies can enhance social-ecological resilience through awareness-raising and changes in consumption. Although economic localisation – a key indicator – is lacking, there is evidence that the Lewes Pound has developed social interactions and changed consumption patterns of its users.
