The €5.10 anti-pollution pass renewed in Île-de-France on June 24.

The heatwave and the ozone pollution peak that have been plaguing Île-de-France for days show no sign of easing. For this Tuesday, June 24, 2026, Île-de-France Mobilités is extending the €5.10 anti-pollution pass, available from network opening. It allows unlimited travel across all Île-de-France lines (metro, RER, bus, tram, Transilien) from 00:00 to 23:59, with Noctilien service included until 5:59 a.m. the following morning. The Police Prefecture is also maintaining the différentiated circulation restrictions across the regional territory.

This pass is not automatic: its activation is decided daily by Île-de-France Mobilités based on real‑time air quality, monitored by Airparif, the reference authority for pollution monitoring in Île-de-France. To know whether it will be active the following day, check the official confirmation on IDFM’s website or via their apps. Note that it must be repurchased every day: a ticket bought the day before does not cover the next day.

How to buy the anti-pollution pass this Tuesday, June 24, 2026?

The anti-pollution pass can be loaded directly onto a Navigo Easy card, or bought through the Île-de-France Mobilités app and the Bonjour RATP app. Ticket counters and vending machines at RATP and SNCF stations also offer it. Do you have a Navigo Liberté+ subscription? You can purchase the pass and load it onto your card or in the app, where it will be prioritized at validation.

Free carpooling and water fountains at train stations

Because of the pollution spike, carpooling is being offered this Tuesday through the Covoit IDFM and Lignes de covoiturage IDFM apps, a practical option for those who can’t avoid driving. A simple way to cut traffic and pollutant emissions at no extra cost.
