Background
On 22 January 2026, the Ministry of Environment publicized a campaign in Pursat province to promote clean action and the implementation of measures to prevent and reduce public air pollution. The statement was presented by ministry spokesperson Khvay Atitya, Secretary of State, in coordination with the Department of Air Quality, Noise and Vibration Management under the General Department of Environmental Protection and with participation from provincial and municipal authorities and local educational institutions.
According to the ministry, the clean sky campaign launched by the Minister of Environment on 15 November 2023 forms part of the ministry’s environmental strategy focused on cleanliness, greenness, and sustainability.
Scope of Application
The update concerns the Ministry of Environment’s nationwide public air quality monitoring and its implementation of measures to prevent and reduce air pollution. The ministry stated that monitoring covers Phnom Penh and provinces across the country through fixed stations, satellite-linked equipment, and mobile air quality inspection vehicles.
The statement also refers to inspections of factories and other potential sources of air pollution as part of ongoing ministry action.
Key Provisions or Decisions
The ministry stated that Cambodia is not causing transboundary air pollution to neighboring countries and that the country’s air quality has not yet been affected by pollution. It attributed recent fog conditions observed over the past week to weather variation rather than smog or degraded atmospheric air quality.
According to the ministry, public air quality is monitored regularly through 59 monitoring locations, including 12 in Phnom Penh and 47 in other provinces. The ministry also reported the use of one satellite-based air quality monitoring system and three mobile air quality monitoring vehicles for inspections nationwide.
The ministry said data from these monitoring devices and stations show that air quality in Phnom Penh and the provinces remains good and complies with standard levels.
Implications for Investors, Businesses, or Compliance
The statement indicates continued ministry monitoring of factories and other potential emission sources as part of public air pollution prevention and reduction measures. Businesses operating facilities with possible air emissions should note that environmental inspections and monitoring activities are being strengthened nationwide.
The update does not announce a new legal instrument, penalty, or compliance requirement, but it confirms ongoing administrative implementation of pollution prevention measures under the ministry’s environmental management mandate.
