Air quality in Sarawak today The AQI right now, city by city

Right now, Sibu has the cleanest air of the 4 cities we track in Sarawak (AQI 36, Good), and Kuching the worst (AQI 54, Moderate). Sibu has the most tree cover, at 49.2% — #13 of 56 cities measured in Malaysia.

Every city is measured the same way, over the same 2 km around its center: the air quality right now, from ground stations where there are any, and its tree cover.

Air quality is the US AQI from ground monitoring stations via OpenAQ where available, otherwise the Open-Meteo / CAMS model, refreshed hourly. Tree cover is measured within 2 km of each city center from Sentinel-2 imagery; the rank compares every city measured in Malaysia.

Is this the same as Malaysia's API (IPU)?

No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. Malaysia's Department of Environment (Jabatan Alam Sekitar) publishes its own Air Pollutant Index, the API or Indeks Pencemar Udara (IPU), every hour for each of its monitoring stations on APIMS (apims.doe.gov.my). Both scales call 0–50 good and 51–100 moderate; above that the IPU runs 101–200 unhealthy, 201–300 very unhealthy and over 300 hazardous. The two use different breakpoints and averaging times, so the numbers for the same hour often differ. For the official IPU reading, check the nearest station on APIMS.

What is causing deforestation in Sarawak?

  • Farms, pasture and plantationscleared for good58% · 1.97 million ha
  • Loggingcan grow back35% · 1.2 million ha
  • Mining and energycleared for good2.7% · 90,800 ha

Also: shifting farming, wildfires, towns and roads, storms, floods and other natural causes, unknown causes.

Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.
