D3.3 Recommendations on circularity indicators for WP8

Effective circular economy indicators allow actors to measure the circularity of their activities, target opportunities for improvement, and communicate their circular economy actions in a consistent and comparable way. This report presents the results of a research programme, which intended to develop indicators at the level of materials, buildings and cities.
An initial review identified around 510 existing indicators within the extant literature, representing sources from the four CIRCuIT cities and internationally. A process of indicator development and prioritisation was then conducted, resulting in a list of recommended indicators including 10 at city-level, 13 at building-level and 11 at material-/product-/component-level. In addition, a number of enablers were identified as being useful to drive the circular economy process. These indicators will assist, at the municipal level in supporting evidence-based policy and planning development, and decision-making to support circularity of material flows within buildings and throughout material lifecycles. They can be used to inform measurement of the environmental, economic and social impact of circular economy decisions and validate their benefits (or not) using LCA (Life Cycle Assessment), LCC (Life Cycle Costing) and social approaches.
