Paris Transport Federation Issues Three-Day Discount Passes to Combat High Ozone Pollution

Paris – May 28, 2026: The Île-de-France region is currently experiencing high concentrations of ozone pollution, exacerbated by sustained high temperatures. To reduce environmental impact and promote eco-friendly travel, Île-de-France Mobilités has implemented temporary measures. From Thursday to Saturday, a special anti-pollution day ticket will be available for 5.10 euros per day. This measure aims to facilitate the use of buses, trains, and the metro, reducing private vehicle trips.

In recent days, ozone levels in the air have peaked, especially in the Paris metropolitan area, posing potential health risks to residents. Experts note that ozone effects intensify under high temperature conditions, which can trigger respiratory diseases and other health problems. Children, the elderly, and respiratory patients are particularly vulnerable.

The transport federation hopes that attractive anti-pollution tickets will encourage more commuters and residents to reduce car use and increase public transport usage, thus lowering pollutant emissions in the region and supporting environmental protection. This measure applies to all public transport in the Greater Paris area.

At the same time, health authorities advise avoiding strenuous outdoor activities during high temperatures and to stay in shaded or air-conditioned environments as much as possible. Currently, 17 departments in the region remain at high alert due to heat and air pollution. Improvements are expected on Friday, and warnings will be gradually lifted.

Île-de-France Mobilités, together with environmental and health authorities, is committed to safeguarding public health while promoting environmental awareness. Similar measures have been implemented in past episodes of elevated pollution levels to improve air quality. This discounted ticket also aims to convey the region’s commitment to sustainable travel.

In addition to reducing traffic emissions, authorities also recommend that citizens make use of public green spaces and stay well hydrated to alleviate the effects of the heatwave. Officials urge the public to heed warnings and act responsibly. The pollution situation will be closely monitored, and further protective measures will be implemented if necessary.

Overall, the introduction of the anti-pollution ticket demonstrates how regional transport and environmental policies work together to address the challenges of climate change and air pollution. Residents of Île-de-France are encouraged to take advantage of this opportunity to shift their travel habits toward more sustainable choices in the short term.
