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.1
