Brazil vs China Air quality index (AQI) and deforestation
Brazil has cleaner air than China right now: its cities average AQI 37 against 114.
At ground stations alone, which measure rather than estimate, the averages are Brazil 46 (60 cities) and China 125 (433 cities). Brazil has lost more forest since 2001. Brazil 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, Brazil or China?
Brazil has lost more: about 76.6 million ha of forest from 2001 to 2025, against 13.5 million ha in China, or 5.7 times as much. 56.2 million ha of Brazil'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: 2016, with 5.41 million ha lost.
Worst year: 2008, with 739,000 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: 304 in Brazil and 639 in China, 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. China rests on 639 cities against 304, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Brazil vs China: your questions answered
Is Brazil cleaner than China?
On air quality, yes, right now: Brazil's cities average AQI 37 against 114 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 Brazil 46 (60 cities) and China 125 (433 cities).
Which country has lost more forest, Brazil or China?
Brazil has lost more: about 76.6 million ha of forest from 2001 to 2025, against 13.5 million ha in China, or 5.7 times as much. 56.2 million ha of Brazil'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, Brazil or China?
Brazil does: its measured cities average 26.2% tree cover against 22.9%, a gap of 3.3 percentage points.
How many cities are the Brazil and China figures based on?
304 measured cities in Brazil and 639 in China. 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 Brazil and China?
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.
