This report aims to map data at national, regional, and global levels, for core Circular Economy Indicators based on the Guidelines for measuring circular economy to assess the availability and accessibility of circular economy indicators. The report evaluates the importance of core indicators in targeted policymaking to advance the shift towards a circular economy and presents country examples of what has been achieved in selected countries. Instances of how circular economy indicators could be used in monitoring targeted policies include resources decoupling, impact decoupling (waste generation and management, greenhouse gas emissions from production activities, pollutants discharges from production activities to water bodies), taxes and government support to circular economy business models, government and business research and development expenditure on circular economy technologies, business investment in circular economy activities and circular economy sector.
