Deforestation · 2001–2025
Which country has lost more forest, United Kingdom or Ukraine?
Ukraine has lost more: about 1.4 million ha of forest from 2001 to 2025, against 607,000 ha in the United Kingdom, or 2.3 times as much. 19,500 ha of Ukraine'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: 2009, with 37,400 ha lost.
Worst year: 2016, with 105,000 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: 92 in the United Kingdom and 42 in Ukraine, 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. United Kingdom rests on 92 cities against 42, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
United Kingdom vs Ukraine: your questions answered
Is United Kingdom cleaner than Ukraine?
On air quality, yes, right now: United Kingdom's cities average AQI 35 against 59 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 United Kingdom 32 (81 cities) and Ukraine 108 (3 cities).
Which country has lost more forest, United Kingdom or Ukraine?
Ukraine has lost more: about 1.4 million ha of forest from 2001 to 2025, against 607,000 ha in the United Kingdom, or 2.3 times as much. 19,500 ha of Ukraine'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, United Kingdom or Ukraine?
Ukraine does: its measured cities average 40.0% tree cover against 26.6%, a gap of 13.4 percentage points.
How many cities are the United Kingdom and Ukraine figures based on?
92 measured cities in the United Kingdom and 42 in Ukraine. 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 the United Kingdom and Ukraine?
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.
