The lack of a commonly accepted and inclusive definition and circularity measurement methodology hampers the transition to a more circular economy. It obstructs the development and access to finance, credit risk assessment, and transferability and replicability of projects and investments across regions and jurisdictions.

The Expert Group of Support to Circular Economy Financing proposes a sector-agnostic Categorisation system for the circular economy that defines categories of activities substantially contributing to a circular economy. This categorisation system is intended as a contribution to the future work of the Sustainable Finance Platform on the EU taxonomy of activities contributing to the circular economy objective.
