Italy air quality today The AQI right now, city by city

Right now the 44 cities Airleaf measures in Italy average AQI 77 (moderate). The worst air is in Reggio nell'Emilia, at AQI 151, and the cleanest in Arezzo, at AQI 8. At ground stations alone, which measure rather than estimate, the average is AQI 88 across 18 cities. 30% of the 44 measured cities are over AQI 100 today, where the air stops being fine for sensitive groups, and 30% have Good air.

Reggio nell'Emilia, at AQI 151 (Unhealthy) on the US EPA index. Everyone should limit long outdoor exertion; sensitive groups more so.

Arezzo, at AQI 8 (Good). Both lists rank current readings, from ground stations wherever Italy has at least three cities with one.

It depends on the city. 13 cities are Good, 18 cities are Moderate, 11 cities are Unhealthy for sensitive groups, 2 cities are Unhealthy. At the national average of AQI 77: Unusually sensitive people should consider limiting long outdoor exertion.

About 547,000 ha from 2001 to 2025, 6% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 50,500 ha of it was cleared for good, for farms, mines or towns.

Perugia, with 61.8% tree cover within 2 km of its center, measured from Sentinel-2 satellite images.

Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
