D3.5 – Open database of policies & technologies

This report describes the methodology used for the generation of the open database of policies and technologies for industrial circularity performance and decarbonisation, which includes circular economy (CE) and decarbonisation interventions across the three core sectors of the project: steel, cement/concrete, and plastics. This database categorises key CE strategies and interventions based on two classificatory axes: the 9Rs framework (refuse, rethink, reduce, reuse, repair, refurbish, remanufacture, repurpose, recycle), and the approach of Narrowing, Slowing, Substituting, and Closing resource loops (NSSC). As most CE measures lead to or overlap with decarbonisation strategies, the database includes a list of technologies and associated costs that contribute to decarbonisation through increased circularity performance. This database complements the Policy Matrix, developed in D3.3., by considering parameters that can be used to transform policy interventions into modelling inputs, so that they can effectively be modelled in MIC3. The dataset also considers key technologies and their associated costs for circularity and decarbonisation. This supports the modelling efforts for the quantification of the costs of the circular and low-carbon transition as part of the model development undertaken in WP4 and, critically, the modelling exercises in WPs 7, 8, and 11.
