Municipal and regional actors have key roles to play in society’s transition to sustainability. However, co-creating sustainable visions and effective governance towards these is a complex challenge and decision-makers often lack an overarching systems perspective. This can lead to solutions in one area causing problems in another, unnecessary goal conflicts, and slow progress. Despite some progress in addressing sustainability issues, capacity to coordinate efforts across sectors to address the full scope of the challenge is often missing. 

The primary aim of this work was to explore how leaders in municipalities and regions can be sufficiently supported in their missions to enhance cross-sectoral strategic sustainable development (SSD) work. This was pursued together with eight Swedish municipalities, two Swedish regions, one Finnish region, and the Swedish eco-municipalities network. An action research project was carried out in two phases over a total of seven years. 

The first phase involved investigating, through focus group discussions, practitioners’ perspectives on what hinders and enables effective sustainability transitions. This revealed a reductionist view also on barriers and enablers and confirmed the need for a more holistic systems perspective. 

The action research included testing of a preliminary model for implementation of the Framework for Strategic Sustainable Development (FSSD) in support of long-term SSD work across sectors. The model was evaluated through observations, dialogues, round-table discussions and a survey, regarding strengths, weaknesses, barriers, and enablers, and was found to be helpful as an illustration of how such work could ideally play out in municipal and regional contexts. However, without external expert facilitators, the work with the model was seen to fade out and needs for complementary tools to avoid that were identified, developed, and combined with the implementation model into a support portfolio. A key asked-for support was ways to involve and engage top leaders into active participation upfront and an approach to achieve this was explored together with one of the participating municipalities. Furthermore, a vagueness in how social sustainability is approached was frequently observed, which called for a study to build a nuanced understanding of municipal social sustainability work.

The second phase of the action research project included a deepened case study of the Finnish region. Despite advanced collaboration platforms and structures, parts of the SSD approach still seemed to have eroded somewhat over time. This circumstance, and other observations, lead to a study of what is required for long-term continuation of SSD work in municipalities and regions, resulting in eight conditions for continuity to be regularly considered.

The combination of the FSSD as core, its implementation model, complementary tools, and the eight conditions for continuity constitutes a support portfolio for SSD work in municipalities and regions as a final collective contribution of this thesis work. This will be further tested and refined in new contextual settings.
