The digital and sustainability transitions have attracted significant attention from the public sector and substantial financial investment. These transitions are of critical importance, particularly within the European Union, which has introduced a range of legislations, funding programmes, and various initiatives to advance them. Notable examples include the European Green Deal, which focuses on sustainability, and the Digital Europe Programme, which aims to drive digital transformation and innovation within the public sector. While recent developments in both areas have gained increasing attention from the scientific community, much of the focus has been placed on explaining the one transition, neglecting the inherent interconnection between these twin transitions in practice. The concept of the twin transition highlights how sustainable and digital transformations can complement each other. Recent studies emphasise the importance of understanding this intersection, particularly in how technology contributes to sustainability efforts and supports sustainable development. In this study, we employ exploratory single-case study research of the city of Leuven in Belgium. Based on our analysis and findings from the transition management literature and perspectives, we explore emerging practices and understanding of civil servants in the twin transition initiatives. We found that the twin transition in the local government of Leuven doesn’t have a coherent strategic vision, and it is rather a high-level policy through which technology is seen as an enabler and a solution to environmental problems.
