Air quality today

Is Thailand cleaner than India?

On air quality, yes, right now. Thailand has cleaner air than India right now: its cities average AQI 62 against 152.

At ground stations alone, which measure rather than estimate, the averages are India 165 (219 cities) and Thailand 67 (28 cities).

75% of the measured cities in India are over AQI 100 today, the point where the air stops being fine for sensitive groups, against 0% in Thailand.

Deforestation · 2001–2025

Which country has lost more forest, India or Thailand?

Thailand has lost more: about 2.84 million ha of forest from 2001 to 2025, against 2.6 million ha in India. 2.49 million ha of Thailand'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.

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: 471 in India and 31 in Thailand, 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. India rests on 471 cities against 31, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.

Frequently asked

India vs Thailand: your questions answered

Is Thailand cleaner than India?

On air quality, yes, right now: Thailand's cities average AQI 62 against 152 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 India 165 (219 cities) and Thailand 67 (28 cities).

Which country has lost more forest, India or Thailand?

Thailand has lost more: about 2.84 million ha of forest from 2001 to 2025, against 2.6 million ha in India. 2.49 million ha of Thailand'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, India or Thailand?

Thailand does: its measured cities average 32.7% tree cover against 27.3%, a gap of 5.5 percentage points.

How many cities are the India and Thailand figures based on?

471 measured cities in India and 31 in Thailand. 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 India and Thailand?

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.
