Historic cross-border agreements for the financing of mobility infrastructure in Greater Geneva

December 2025

On 27 November 2025, nine public authorities from the Greater Geneva area signed agreements aimed at strengthening cross-border mobility. More ambitious than an initial initiative launched eleven years earlier, this package - comprising a protocol, an agreement and a letter of intent- sets out the financing of cross-border transport infrastructure for 2027-2030.

With nearly 650,000 border crossings made every day, these agreements establish a joint governance framework, bringing together the Canton of Geneva, the Department of Ain and the Department of Haute-Savoie. The aim is to streamline commuter traffic by developing public transport services (high-level service buses, Ferney-Voltaire tram, large-capacity park-and-ride facilities, prioritisation of public transport on certain routes and redevelopment of an urban boulevard).

The agreements also provide for an increase in the financial contribution of the Cantons of Geneva and Vaud to the operation of cross-border bus lines from 40% to 60%, while the French partners would reinvest the €2.4 million annual margin to improve feeder lines. These agreements will be put to a vote in the Canton of Geneva.
