Mapping dashboards are transformative tools in urban governance, offering real-time data visualization to support sustainable development, enhance decision-making, and foster citizen engagement. In this context, while some critics warn that mapping dashboard can embody an extremely technocratic form of city governance, others praise their potential for deeper forms of citizen engagement and participation in planning. As these tools are increasingly used by cities to achieve and monitor the transition to more sustainable futures, it is important to understand the extent to which urban dashboards are true to their participatory potential. This dissertation analyses the role of mapping dashboards in supporting sustainable urban development in Turin by drawing comparative insights from Helsinki and Copenhagen.
