The key role of capitals in the transport system transition

To mark World Cities Day 2025, the POLIS Capitals Working Group has published a new policy brief showcasing how capitals, which are often the most populous cities and regions, are primary agents in shaping the European mobility agenda and must be recognised as such. Bringing together 18 of the 27 EU capitals, the Capitals Working Group provides a unique platform for collaboration and dialogue among these urban leaders. Through this publication, POLIS aims to amplify the voice of capitals, highlight their specific challenges, and underline their vital contribution to achieving EU sustainability and mobility goals.

The policy brief highlights the main obstacles faced by European capitals in meeting expectations regarding their roles in international connectivity, transport user services and information, and improving air quality and sustainability. These expectations are high, given the size of capitals’ populations, economic power, and historical heritage—factors that create both infrastructure legacies and opportunities for stakeholder cooperation and innovation. However, these ambitions also require dedicated funding, clear guidelines, and strong support at the European level.
