According to the *World Air Quality Report* from IQAir, Indonesia had the worst air quality in ASEAN in 2022.

IQAir measured this based on the high concentration of particulate matter (PM) 2.5 in Indonesian air.

PM 2.5 are particles with a diameter of approximately 2.5 micrometers (1 micrometer = 0.001 millimeter).

Because of their extremely small size, these particles can remain suspended in the air for a long time, and can be inhaled by humans, triggering health problems such as asthma, lung disease, heart disease, and even cancer.

These particles generally originate from wood burning, stove smoke, motor vehicle exhaust, energy combustion residue from power plants and industries, and cigarette smoke.

There are also naturally occurring particles classified as PM 2.5, namely plant spores, pollen, wildfire smoke, and volcanic ash.

According to the World Health Organization (WHO), the ideal air quality standard has a PM 2.5 concentration weight of between 0 and 5 micrograms per cubic meter.

However, IQAir recorded an average PM 2.5 concentration in Indonesian air in 2022 of 30.4 micrograms per cubic meter. This figure is six times higher than the WHO ideal standard, making Indonesia's air quality the worst in ASEAN.

"Air pollution in Indonesia originates from coal-fired power plants, forest fires, and peatland degradation, while pollution in large cities mainly comes from vehicle emissions," said the IQAir team in their report.

Cambodia had the best air quality in the region, with PM 2.5 concentration levels as shown in the graph. Meanwhile, two other ASEAN countries, Brunei Darussalam and Timor-Leste, were not included in the index.

IQAir obtained this data from hundreds of air monitoring stations belonging to government agencies, research institutions, and private companies spread across 296 cities and 9 Southeast Asian countries.

The data collected from these monitoring stations were then validated and recalibrated using IQAir's platform.

"With this data, IQAir wants to inform and inspire governments, educators, researchers, non-profit organizations, companies, and the public to collaborate in raising awareness of air quality," said the IQAir team.
