TRANSIENCE D3.2 Open model development strategy

This report outlines the development strategy for the MIC3 modelling framework, which aims to simulate European industry's circular economy and climate change mitigation efforts. The report leverages findings from previous research and stakeholder workshops to inform the strategy. It proposes a scheme for the development of MIC3's individual modules, including data exchange protocols, and explores the challenges of integrating circular economy and decarbonisation measures into a large, interconnected model ecosystem. The report also analyses existing policies and strategies related to the circular economy in three focal sectors: steel, cement, and plastics, highlighting both progress and gaps in integrating decarbonisation and circular economy initiatives. It then concludes by outlining a five-step open model development strategy for MIC3, emphasising the importance of iterative development and collaboration with stakeholders.
