On 9 July 2026, the European Commission adopted an Implementing Regulation establishing a common set of urban mobility indicators to be used across the European Union (“Implementing Regulation”). Adopted under the revised TEN-T Regulation, the new rules require Member States to collect and report data on selected sustainability urban mobility indicators (“UMIs”), providing cities, national authorities and EU institutions with a more consistent basis for monitoring progress. The Implementing Regulation is available at this link and its annex listing specific obligatory UMIs at this link.

The harmonised UMIs cover three key areas: sustainability, safety and accessibility. The Implementing Regulation sets out the technical and procedural requirements for data collection and reporting, while still allowing Member States flexibility to take account of their national, regional and local circumstances.

The Implementing Regulation will enter into force 20 days after its publication in the Official Journal of the European Union. Member States must submit their first set of urban mobility data by the end of 2027, with updates required every four years thereafter. According to the Commission, the new reporting framework represents an important step towards improving the quality and comparability of urban mobility data across the EU.
