This paper introduces a framework aimed at evaluating stakeholder involvement within Hubs for Circularity (H4C), which play a critical role in advancing the circular economy. It demonstrates the significance of collaboration among stakeholders and the need for a structured approach to assess the effectiveness of H4C initiatives. As a result of the literature review synthesis, the paper proposes a novel and actionable framework for stakeholder engagement. It is composed of several key elements: it begins with the identification and analysis of the different stakeholder groups participating in H4C projects. Next, it advocates for a comprehensive review of the factors influencing H4C implementation through an analysis of drivers, barriers, and enablers. It also emphasizes the development of success criteria aligned with the Sustainable Development Goals to measure the outcomes of H4C initiatives. The paper concludes by proposing future research directions, such as integrating the Societal Readiness Level and utilizing social network analysis and regional input-output modeling to assess the socio-economic impacts of H4C projects. Overall, the paper highlights the critical role of stakeholder engagement and effective evaluation frameworks in the success of H4C initiatives and the advancement of sustainability goals.
