Air pollution has been recognized by the World Health Organization (WHO) as a severe environmental and health threat caused by various factors, including household and industrial emissions of greenhouse gases, vehicular exhaust, agricultural activities, and inefficient environmental management. In response to the pressing concern of air quality, notably the significant impact of PM2.5 on daily life and public health, the Thai government has worked in collaboration with, among others, academics and civil society organizations to address the air pollution crisis.
