This report aims to map data at national, regional, and global levels, for core Circular Economy (CE) Indicators of the Joint UNECE/OECD Guidelines for measuring circular economy part A: conceptual framework, statistical framework and indicators (United Nations Economic Commission for Europe [UNECE] 2023). The guidelines were developed by a Task Force that was set-up in 2021 to assess the availability and accessibility of circular economy indicators, and was formed by a significant number of international organizations1, including UNEP, and countries representatives. The members of the Task Force assessed the available information on circular economy, homogenised the concepts and definitions, as well as proposed an aspirational indicators framework that could be used by any country to assess their progress towards shifting to circular economy.
