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

Paris – 05/28/2026: The Île-de-France region is currently affected by a high concentration of ozone, which is increased by the prolonged period of heat. To reduce environmental pollution and increase the use of eco-friendly means of transport, Île-de-France Mobilités has taken a temporary measure. From Thursday until Saturday inclusive, a special anti-pollution ticket for public transport will be offered at a price of 5.10 euros per day. The goal is to facilitate the use of buses, trains, and metro and to reduce private traffic.

The ozone concentration in the air has reached a maximum level in recent days, which can pose health risks to the population, especially in the Paris metropolitan area. Experts point out that ozone has a stronger effect at high temperatures and can cause respiratory problems and other health complications. Especially children, elderly people, and patients with respiratory diseases are at risk.

The transport network hopes that, thanks to this affordable anti-pollution ticket, many commuters and residents will be motivated to leave their cars and opt more for public transport. This aims to reduce pollution and contribute to environmental protection. The measure is valid for all means of public transport in the greater Paris area.

At the same time, health authorities recommend avoiding physical exertion outdoors on hot days and seeking shaded or air-conditioned places. Currently, a high alert level remains in 17 departments of the region due to heat and air pollution. A slight improvement is expected on Friday, so warnings will be gradually lifted.

Île-de-France Mobilités works jointly with environmental and health authorities to ensure the protection of the population while promoting environmentally friendly behavior. In the past, the transport network has already implemented similar measures in response to increases in pollutants to improve air quality. The current offer also aims to send a message in favor of sustainable mobility in the region.

In addition to reducing traffic emissions, it is recommended to use public green spaces and drink enough water to mitigate the effects of the heat wave. Authorities make a call to citizens to pay attention to alerts and act responsibly. The evolution of the pollution situation is being closely monitored to introduce new protective measures if necessary.

Overall, the introduction of the anti-pollution ticket demonstrates how regional transport and environmental policies can go hand in hand to address the challenges of climate change and air pollution. Residents of Île-de-France are encouraged to take advantage of this opportunity to temporarily change their mobility habits towards more sustainable alternatives.
