According to data from the Ministry of Environment and Forestry (KLHK) [https://databoks.katadata.co.id/tags/klhk](https://databoks.katadata.co.id/tags/klhk), Indonesia's air quality [https://databoks.katadata.co.id/tags/udara](https://databoks.katadata.co.id/tags/udara) in 2021 showed a slight improvement compared to 2020.

KLHK recorded a national Air Quality Index (AQI) score of 87.23 in 2021. This figure is 0.02 points higher than the 2020 national AQI of 87.21.

This achievement also exceeded the target set in the National Medium-Term Development Plan (RPJMN), which aimed for a national AQI score of 84.2 in 2021.

KLHK reported that in 2021, 28 provinces achieved their AQI targets, while 6 other provinces remained below target. Nevertheless, the majority of Indonesian provinces are considered to have good air quality.

The AQI has a score range of 1-100, calculated based on the annual average concentration of polluting gas compounds in the lowest atmospheric layer (ambient air) in regencies/cities.

The polluting gas compounds used as AQI parameters are sulfur dioxide (SO2) and nitrogen dioxide (NO2).

SO2 is generally emitted from industrial activities and diesel vehicles using solar or other sulfur-containing fuels.

NO2 is emitted from coal-fired power plants, charcoal burning, motor vehicles, and other community activities using gas and gasoline fuel.
