This report examines how mission governance supports city-level climate neutrality transitions across four European Mission Cities: Umeå, Oslo, Turku and Aachen. It focuses on the internal governance arrangements, coordination mechanisms, roles, mandates and institutional practices through which municipalities organise themselves to deliver ambitious climate-neutrality commitments.

Across the four cases, mission governance is understood not as a single organisational model, but as a set of structures, routines and ways of working that connect long-term political commitments with everyday administrative practice, departmental implementation and wider city partnerships.
