Circular economy business models allow Europe to address the challenges posed by the increasing scarcity and depletion of natural resource to ensure sustained economic development, minimise environmental impact and maximise social welfare. Transitioning from linear to circular economy business models, however, is not simple. There are numerous obstacles at company and value chain levels, as well as from EU and local level policy perspectives. This report provides a simple, yet rich overview of the barriers and enablers of circular economy business models as identified by stakeholders, drawing upon a range of interviews, workshops and events, and a survey conducted with representatives of the European business sector.
