Systems analysis could be an essential approach to shape resource efficiency policy in a sustainable long term perspective. Various actors and stakeholders with partly opposing interests form part of a highly interconnected system. The integration of causal chains, feedback loops and delays within the system are therefore central to identify the right leverage point for resource efficiency policy. In the SimRess project a participatory approach helped designing the simulation model. The present report documents and summarizes the various results of the workshops and the systems analysis.
