The Cities’ Circular Action Plans (CCAP) are roadmaps for the transition toward circular and regenerative cities. The report containing the CCAP gathers the competences of the consortium to create viable ways for the pilot cities to implement CE practices and ensures replicability. In line with the overall structure of the project, The REFLOW Cities’ Circular Action Plan operates on two levels: Project Level and Pilot Level. On a Project Level, the CCAP is described as the overall Roadmap that determines the general direction and modes of organising of the whole consortium. On a Pilot Level, the CCAP refers to the specific action plans created by the REFLOW cities, within the broader Roadmap of the project. The action plans are mainly concerned with the management and implementation of local activities aimed at achieving the pilot-specific objectives. The CCAP gathers the resources created and implemented by the project consortium to overcome the challenges encountered or expected by the pilot cities thus fostering replicability. The CCAP will turn into a living, online document that will provide resources for cities to become regenerative and implement circular economy practices. The CCAP as a digital resource will last beyond the life of the REFLOW project.
