The Paris transport consortium introduces a three-day anti-pollution ticket due to the high concentration of ozone

Paris – 28.05.2026: The Île-de-France region is currently affected by a high concentration of ozone, exacerbated by the prolonged heat period. To reduce the environmental impact and increase the use of sustainable means of transport, Île-de-France Mobilités has adopted a temporary measure. From Thursday until Saturday inclusive, a special anti-pollution ticket for local public transport will be offered at the price of 5.10 euros per day. The goal is to facilitate the use of buses, trains, and subways and reduce private traffic.

The ozone concentration in the air reached a peak in recent days, with possible health risks especially in the Paris metropolitan area. Experts emphasize that ozone has greater effects at high temperatures, causing respiratory disorders and other health problems. Children, the elderly, and people with respiratory diseases are particularly at risk.

The transport consortium hopes that the reduced-price anti-pollution ticket will motivate many commuters and residents to leave their cars at home and prefer public transport. This should help reduce pollution in the region and promote environmental protection. The measure applies to all public transport in the greater Paris metropolitan area.

At the same time, health authorities recommend avoiding physical efforts outdoors during hot days and seeking shaded or air-conditioned places. Currently, a high alert level for heat and air pollution still applies to 17 departments of the region. Slight improvement is expected on Friday, so the alerts will be gradually lifted.

Île-de-France Mobilités collaborates with environmental and health authorities to ensure the protection of the population while promoting environmentally friendly behavior. In the past, the consortium has adopted similar measures in case of increased pollutant concentrations to improve air quality. The current initiative also aims to send a signal for sustainable mobility in the region.

Besides reducing traffic-related emissions, it is recommended to use public green spaces and to drink adequate amounts of water to alleviate the effects of the heat wave. Authorities invite citizens to carefully follow the alerts and to behave responsibly. The pollution situation will be constantly monitored to adopt further protective measures if necessary.

Overall, the introduction of the anti-pollution ticket demonstrates how regional transport and environmental policies can work in synergy to address challenges arising from climate change and air pollution. The inhabitants of Île-de-France are encouraged to take this opportunity to temporarily change their mobility habits toward more sustainable alternatives.
