This study explored how social aspects for stakeholder engagement are being addressed and incorporated in climate action plans (CAPs). This focus was chosen to address the knowledge gap in research on social conditions for climate action which has been found to provide barriers to achieving deep decarbonisation. The thesis conducted a case study of two cities, Copenhagen (Denmark) and Stockholm (Sweden). Each city’s CAP was analysed through a thematic document analysis that explored through what measures each city aim to achieve stakeholder engagement for local climate action.    Five overarching themes were identified through a literature review and used as an analysis framework: citizen engagement, private sector engagement, stakeholder collaboration, awareness development and advocacy. For both CAPs, the results showed an extensive variation for measures that contributed to each theme. The main findings were that measures should focus on developing collaborations, partnerships, networks, knowledge, awareness, skills, green procurement policies and stricter environmental regulations to support the level of stakeholder engagement needed for deep decarbonisation. Also, to focus on advocation measures, as well as measures aimed at developing knowledge and support to accelerate systematic change. In addition, it was found that cities need to focus on ensuring higher levels of equity and formalize extended citizen involvement for more inclusive and fair transitions. Findings also highlighted similarities and differences between the two CAPs, what lessons could be learned from these and connected these findings to how climate action could be further developed.
