AKP Phnom Penh, February 17, 2026 --

Cambodia’s air quality was assessed as “Good” from 7:00 a.m. on Feb. 16 to 7:00 a.m. on Feb. 17, 2026, according to the Ministry of Environment.

The Ministry reported that the average concentration of particulate matter during this period was 33.37 microgrammes per cubic metre (µg/m³), well below the national standard threshold of 50 µg/m³. Based on this level, the Air Quality Index (AQI) across the country was classified as “Good.”

The Ministry noted that air pollution is largely caused by human activities. During the dry season, concentrations of particulate matter PM10 and PM2.5 tend to increase, mainly due to agricultural residue burning, rice stubble burning, forest and grassland fires, open burning of waste and plastic materials, as well as naturally occurring fires.

Other major sources of air pollution include emissions from vehicles and factories, dust from construction sites, and road dust.

To maintain good air quality throughout the dry season, the Ministry of Environment called on the public and relevant stakeholders to actively participate in preventing and reducing air pollution. Key measures include preventing forest fires, grassland burning, agricultural waste burning, land clearing by fire, rice stubble burning, open burning of garbage, solid and plastic waste, textile scraps, and fires at landfill sites.

The Ministry also urged cooperation in reducing emissions from industrial facilities and vehicles, as well as minimising dust pollution from construction activities, to help ensure that Cambodia’s air quality remains at a healthy level.
