An ongoing study by the Clean Air Initiative for Asian Cities, summarizing air quality data from 20 cities in Asia shows that, on average, there has been a moderate to slight decrease in pollution levels for sulfur dioxide (SO2), total suspended particulate matter (SPM), and fine particulates, also known as PM10. Although particulate matter remains at levels harmful to human health, SO2 levels are now, on average, below the guideline values set by the World Health Organization – proving that air quality management policies and measures can work in Asia.
