First 'car-free' day in Paris sees massive drop in pollution and noise "Airparif, which measures city pollution levels, said levels of nitrogen dioxide dropped by up to 40% in parts of the city on Sunday 27 September - and there was almost one-third less nitrogen dioxide pollution on the busy Champs Elyées than on a similar Sunday.

Bruitparif, which measures noise, said sound levels dropped by half in the city centre.

...City mayor Anne Hidalgo said on Twitter: “We might envisage days without cars more often … perhaps even once a month.”"
