Is this the same as Singapore's PSI?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. Singapore's National Environment Agency (NEA) reports the 24-hour Pollutant Standards Index (PSI) for five regions of the island: north, south, east, west and central. Both scales call 0–50 good and 51–100 moderate; above that the PSI runs 101–200 unhealthy, 201–300 very unhealthy and over 300 hazardous. Because the PSI averages 24 hours, it moves more slowly than an hourly reading, and NEA suggests its 1-hour PM2.5 reading for plans right now. The official figures are on haze.gov.sg.

How much forest has Singapore lost?
Since 2001, Singapore has lost about 2,220 hectares of forest (about 3,100 football pitches): 17% of the forest it had in 2000. Most of it (99%) was deforestation, forest cleared for good, mainly for towns and roads.

Singapore as a whole
21.8% of Singapore was forested as of 2024, against a 30% benchmark. Closing that gap nationally would take roughly 5.9M trees across 5.9K hectares. Source: World Bank (FAO).

Frequently asked
Air quality in Singapore: your questions answered
What is the air quality in Singapore today?
Right now the 6 cities Airleaf measures in Singapore average AQI 66 (moderate). The worst air is in Jurong Town, at AQI 84, and the cleanest in Punggol, at AQI 61. At ground stations alone, which measure rather than estimate, the average is AQI 66 across 6 cities. None of the 6 measured cities is over AQI 100 today.
Which city in Singapore has the worst air right now?
Jurong Town, at AQI 84 (Moderate) on the US EPA index. Unusually sensitive people should consider limiting long outdoor exertion.
Which city in Singapore has the cleanest air right now?
Punggol, at AQI 61 (Moderate). Both lists rank current readings, from ground stations wherever Singapore has at least three cities with one.
Is the air in Singapore safe to breathe today?
It depends on the city. 6 cities are Moderate. At the national average of AQI 66: Unusually sensitive people should consider limiting long outdoor exertion.
How much forest has Singapore lost since 2001?
About 2,220 ha from 2001 to 2025, 17% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 2,200 ha of it was cleared for good, for farms, mines or towns.
How does Airleaf measure air quality in Singapore?
Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Singapore's PSI is a different scale, explained on this page. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
