Air quality today
What is the air like in Rome and Turin right now?
Rome has cleaner air than Turin right now: AQI 24 (Good) against 124 (Unhealthy for sensitive groups). PM2.5 is setting the index in both.
Turin's PM2.5 is about 3.0× the WHO's 24-hour guideline of 15 µg/m³.
Both readings come from nearby ground stations.

Deforestation · 2001–2025
Which has lost more forest, Rome or Turin?
Turin has lost more: about 92 ha of forest within 10 km of its center from 2001 to 2025, against 38 ha around Rome. 46 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2022, with 9 ha lost.
Worst year: 2020, with 15 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.
More on the method on the About Airleaf page.
Frequently asked
Rome vs Turin: your questions answered
Is Rome cleaner than Turin?
On air quality, yes, right now: Rome reads AQI 24 against 124, a gap of 100 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 6 days, on modeled daily averages, Rome averaged AQI 59 against 97, and it was the cleaner of the two on 6 of those days.
Is it safe to exercise outdoors in Rome and Turin today?
In Rome, at AQI 24: Air quality is satisfactory for everyone. In Turin, at AQI 124: Sensitive groups should limit long or intense outdoor activity.
Which has lost more forest, Rome or Turin?
Turin has lost more: about 92 ha of forest within 10 km of its center from 2001 to 2025, against 38 ha around Rome. 46 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Rome or Turin?
Turin has more tree cover: 17.2% of the land within 2 km of its center against 16.2% around Rome, or about 52,847 trees against 50,894. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Rome and Turin need?
Rome needs about 43,354 more to reach its canopy target of 30%, and Turin about 54,690 to reach 35%. The target starts at 30% of the land and rises where air quality is poor.
Are Rome and Turin measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Rome vs Turin comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 16, 2026 and Sep 15, 2026), and the forest figures are published yearly.
