CAI-Asia recognizes that while information and knowledge on air quality management are increasingly generated in Asia, they are fragmented in different documents and websites. To ensure that decision-makers have better access to knowledge on clean air management that can assist in policy development, CAI-Asia has been releasing publications and presentations that provide a comprehensive and comparative assessment of the status and challenges of air quality management in Asia. Starting with only 20 cities in 2003, CAI-Asia now has compiled information on air quality and pollutant levels from over 200 Asian cities. A main finding is that the air in more than six out of ten developing cities in Asia is unhealthy based on our survey of 234 cities of particulate matter, or PM10 levels against WHO interim targets, and only about one percent or three surveyed cities have clean air.
