In an unprecedented move for Switzerland, Geneva has temporarily abolished public transit fares across its canton as part of emergency measures to reduce hazardous air pollution levels. The initiative aims to lower vehicular emissions amid soaring ozone levels and record-breaking heat.
Geneva’s anti-smog monitoring system recorded ozone concentrations exceeding 180 micrograms per cubic meter over a 24-hour period, well above the World Health Organization’s safety threshold. This spike coincided with temperatures reaching 37°C (98.6°F) and sustained heat warnings for western and southern Switzerland. Atmospheric conditions—including high heat, stagnant air, and cloudy skies—have intensified ozone buildup by limiting dispersion.
Starting Wednesday, all buses, trams, trains, and boats in the canton of Geneva are free to board. Ticket requirements have been suspended until pollution levels improve. Additionally, the city center now restricts vehicle access between 6 a.m. and 10 p.m. to only low-emission vehicles, aiming to further reduce nitrogen oxide and other harmful emissions.
Swiss authorities underscore that these measures, launched under an emergency protocol, are designed to encourage commuters and tourists to switch from private cars to public transit—thus curbing traffic pollution during the current crisis.
