France vs Spain Air quality index (AQI) and deforestation
Spain has cleaner air than France right now: its cities average AQI 21 against 34.
At ground stations alone, which measure rather than estimate, the averages are France 34 (33 cities) and Spain 24 (30 cities). Spain has lost more forest since 2001. France has more tree cover in its cities.
Updated . Lower is better on the US EPA index: 0–50 is Good, above 300 is Hazardous. Measured by Airleaf.

Deforestation · 2001–2025
Which country has lost more forest, France or Spain?
Spain has lost more: about 1.79 million ha of forest from 2001 to 2025, against 1.62 million ha in France. 81,100 ha of Spain's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
The whole country, from the yearly satellite maps of forest loss: unlike the city averages above, this counts every forest, not just the land around cities.
Worst year: 2010, with 143,000 ha lost.
Worst year: 2025, with 153,000 ha lost.

Reading these numbers
What a country average is, and is not
It is a mean of cities
Not a national statistic. Each figure is the average across the cities Airleaf has measured: 39 in France and 57 in Spain, each read over the same 2 km radius, on the US EPA index. Rural land and unmeasured towns are not in it.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. Spain rests on 57 cities against 39, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
France vs Spain: your questions answered
Is Spain cleaner than France?
On air quality, yes, right now: Spain's cities average AQI 21 against 34 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather. At ground stations alone, which measure rather than estimate, the averages are France 34 (33 cities) and Spain 24 (30 cities).
Which country has lost more forest, France or Spain?
Spain has lost more: about 1.79 million ha of forest from 2001 to 2025, against 1.62 million ha in France. 81,100 ha of Spain's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
Which country has more tree cover, France or Spain?
France does: its measured cities average 25.5% tree cover against 14.3%, a gap of 11.2 percentage points.
How many cities are the France and Spain figures based on?
39 measured cities in France and 57 in Spain. Every one was read the same way, so the two averages are directly comparable, but a country with more measured cities has the more settled figure.
Why are there two air quality averages for each country?
The first covers every measured city, using a ground station where one is close and a model estimate everywhere else. The second counts only cities with a current station reading, which is measured rather than estimated but covers fewer places. Airleaf's world rankings use the station figures only.
Does this cover the whole of France and Spain?
The air and tree figures are not: they are the cities Airleaf has measured, each over the same 2 km radius, so treat them as a comparison of urban air and urban tree cover. The forest figures are: they count every forest in the country.
