The study - the first to assess the impact of the ZTL - reveals improvements in air quality "sensibly greater on certain routes directly affected by the reduction of traffic".
The ZTL has reduced traffic in central Paris. Airparif is also observing a measurable decrease in nitrogen dioxide pollution.
With a reduction in traffic from 18 to 29% in these two spaces, the concentration of nitrogen dioxide, a pollutant emitted by vehicles, has decreased significantly in the air of France according to an Airparif study.
A study, published on Friday 25 September, confirms the benefits of the limited traffic area on air quality in Paris. Around the ZTL, measured concentrations of nitrogen dioxide are decreasing, according to AirParif. Results that "convince that policies to reduce road traffic contribute to reducing the exposure to air pollution of the inhabitants". - Limited traffic area: in Paris, residents breathe less nitrogen dioxide (Health and well-being).
The study shows a reduction in road traffic in Paris intramuros between 2023 and 2025, particularly marked within the ZTL (-18%) covering the first four arrondissements of the capital that cars are no longer allowed to travel in the city.
Since the introduction of the zone with limited traffic (ZTL) in the centre of Paris and the redevelopment of the Porte Maillot, air quality has improved in Paris, according to a study published by Airparif on Friday. The decrease in traffic leads to a decrease in pollutant emissions.
