The Council of State had sentenced the French State to a fine of 10 million euros in 2021 for non-compliance with European air quality standards in five metropolises, including Grenoble (Isère).
If the State was still sentenced to two fines of 10 million euros on Monday, Grenoble is no longer overrun in terms of nitrogen dioxide concentration;

The European regulatory thresholds (40 µg/m³) are however still much higher than those of the World Health Organization (WHO), set at 10 µg/m³.
These were modified in the fall of 2021 in order to better correspond to what we now know about the health impact of this pollution.
To continue this depollution, the metropolis will deploy, from July 2023, a low-emissions zone for all vehicles.
A large part of nitrogen dioxide emissions are indeed linked to road traffic.
It should be noted that, while the Council of State's decision also takes into account the levels of fine particles (PM10), it does not concern those of fine particles of small sizes (PM2.5) linked to wood heating in an open hearth.
