ROBIN has successfully established and mobilized 5 Multi-Actor Regional Constellations (MARCs) in the 5 regions of the project, including the to-date participation of 47 members, representing all quadruple helix stakeholder groups, with the mission to drive the creation and adaptation of the ROBIN governance models throughout the project implementation. A baseline analysis of the bioeconomy policy mix, as well as the barriers and opportunities for the uptake of regional bioeconomy governance models was conducted in each region, deepened by means of 21 in-depth semi-structured interviews. An analysis of 57 bioeconomy governance models and 20 in-depth case studies resulted to the development of a typology of Circular Bioeconomy Governance Models. An inventory of 75 good practices of regional governments supporting local operators and innovation developers via business models and social measures was developed. Five workshops for co-creating new and improved regional governance models and practices with key stakeholders were held with 69 participants in total, and a value proposition and a new or improved regional governance model linked to them was created in each region. Each regional node (ROBIN’s Regional authorities with the partners of their region), inspired by a Support Actions Portfolio (SAP) of 50 support actions, developed its own detailed Regional Action Plan with 10 dedicated Support Actions, contributing to the realization of the regional governance model. In parallel, the three core tools of the project were developed: i) the Circular Bioeconomy Governance Model Canvas (CBGMC) for developing a region’s circular bioeconomy governance model ii) the Bioeconomy Policy Monitoring Tool (PMT), for the evaluation of the performance of governance models with respect to Environmental, Socioeconomic and Governance (ESG) and territorial Responsible Research and Innovation (RRI) aspects and iii) The Environmental Protection Planning (EPP) tool for the identification of potentially non-environmentally friendly practices across environmental management areas. The ROBIN Toolbox, a user-friendly, online toolbox offering guidance, knowledge and practical tools for reginal authorities in developing circular bioeconomy governance models and strategies was developed, comprising of the following main components: i) the ROBIN Knowledge Platform (inventory of regional bioeconomy governance models, inventory of good practices of regional governments supporting local operators and innovation developers); ii) the ROBIN Tools (CBGMC, PMT, EPP) and iii) the ROBIN Support Actions Portfolio (Inventory of potential Support Actions and Support Actions typology matrix). The regional nodes elaborated the plans that will guide the validation of the ROBIN Toolbox in each of each region, detailing the Toolbox validation actions and the 10 Support actions they will implement. A plan for involving other EU regional authorities in the ROBIN Toolbox beta testing was also developed. Preliminary steps were taken to set the validation plans in motion, and the the project’s Monitoring, Assessment and Evaluation (MAE) framework was developed. Finally, we commenced discussions about the exchange of best practices and lessons learnt among the regions and projects interested in regional bioeconomy governance support.
