Geneva temporarily made public transport free across the city on Wednesday as part of emergency measures to address a spike in harmful ozone pollution.
Authorities said ozone levels had surpassed 180 micrograms per cubic meter over 24 hours, exceeding environmental health safety limits and posing risks to residents’ respiratory health.
Officials attributed the pollution spike to high temperatures, low cloud cover, and stagnant air, which slow the dispersion of pollutants from vehicles and industrial activity.
The canton encouraged residents to switch from private cars to buses, trams, trains, and boats to reduce emissions and support more sustainable urban mobility.
Ticket inspections were suspended during the emergency period, ensuring that all public transport users could travel without charge.
High-emission vehicles are restricted on city roads between 6 a.m. and 10 p.m., with only lower-emission cars allowed to circulate.
City authorities framed the measure as part of a broader strategy to reduce nitrogen oxide emissions and protect public health while promoting environmentally responsible transport choices.
The temporary free transport initiative demonstrates how cities can use policy tools to encourage shifts toward low-carbon mobility during extreme weather and pollution events.
Urban planners said reducing reliance on private vehicles not only cuts emissions but also decreases congestion, improves air quality, and enhances overall urban resilience.
Public health officials urged vulnerable populations, including the elderly, children, and people with preexisting respiratory conditions, to minimize outdoor exposure until air quality improves.
Experts highlighted that climate change is increasing the frequency and intensity of heatwaves, making integrated urban sustainability measures essential for protecting residents and ecosystems.
Geneva’s approach reflects a growing European trend of combining short-term emergency interventions with long-term planning to transition toward greener, healthier, and more sustainable cities.
