Business leaders and governments alike are acknowledging that continued long-term value creation requires a new economic model that is less dependent on cheap, easily accessible materials and energy, and that is able to restore and regenerate natural capital. In its research to date, the Ellen MacArthur Foundation has demonstrated that the circular economy is a clear value creation opportunity. As many policymakers become interested in this promising model, they envisage the important role they can play in creating the right enabling conditions and, as appropriate, setting direction to unlock it. This report looks at the circular economy opportunity from a country and policymaker perspective, and aims to provide policymakers with an actionable toolkit to help accelerate the transition towards the circular economy.
