Bangladesh vs Canada Air quality index (AQI) and deforestation
Canada has cleaner air than Bangladesh right now: its cities average AQI 25 against 132.
At ground stations alone, which measure rather than estimate, the averages are Bangladesh 215 (9 cities) and Canada 24 (55 cities). Canada has lost more forest since 2001. Bangladesh has more tree cover in its cities.

Deforestation · 2001–2025
Which country has lost more forest, Bangladesh or Canada?
Canada has lost more: about 65.6 million ha of forest from 2001 to 2025, against 263,000 ha in Bangladesh, or 250 times as much. 899,000 ha of Canada'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: 2017, with 27,500 ha lost.
Worst year: 2023, with 8.38 million 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: 45 in Bangladesh and 59 in Canada, 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. Canada rests on 59 cities against 45, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Bangladesh vs Canada: your questions answered
Is Canada cleaner than Bangladesh?
On air quality, yes, right now: Canada's cities average AQI 25 against 132 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 Bangladesh 215 (9 cities) and Canada 24 (55 cities).
Which country has lost more forest, Bangladesh or Canada?
Canada has lost more: about 65.6 million ha of forest from 2001 to 2025, against 263,000 ha in Bangladesh, or 250 times as much. 899,000 ha of Canada'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, Bangladesh or Canada?
Bangladesh does: its measured cities average 52.9% tree cover against 33.1%, a gap of 19.8 percentage points.
How many cities are the Bangladesh and Canada figures based on?
45 measured cities in Bangladesh and 59 in Canada. 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 Bangladesh and Canada?
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.
