Paris has made some incredibly ambitious and highly controversial policy changes to improve the city's air quality. In the meantime, there's a new app from Valeo to determine the state of the air quality in the city.

Jake Richardson shares news of a new app by Valeo that provides a real-time air quality map of the city of Paris, and could eventually navigates users around the areas with the worst air quality.
Valeo equipped 19 vehicles, 15 Keolis public transportation vehicles and four G7 Green taxis, with particle sensors. "Valeo’s sensors are designed to collect information on the concentration levels of various pollutants, including fine particles (PM 10 and PM 2.5), carbon monoxide, nitrogen dioxide, sulfur dioxide, and ozone," explains Richardson.
"Once recorded, these data points are fed into an instantaneous air quality index (AQI) map."
Eventually the app developers hope to allow navigation services that allow users to avoid areas in the city with the worst pollution.
