    According to different studies, air pollution in India has reached to an alarming level. Delhi has been ranked as the top most polluted city of the world, and 13 out of top 20 polluted cities are in India. Sensing the need of checking air pollution, central government with assistance of SAFAR have created an air quality index to keep a tab on the quality of air , and levels of key pollutants.

    Launched in various metros all over country, Air quality index monitors level of eight key pollutants, No2, CO, O3, CO2, NH4, Particulate matter 2.5, Particulate matter 10 and black carbon. It has adopted a colour coded approach where red displays severe to very severe level of pollution, amber depicts moderate pollution, while green colour displays relatively safe concentration of pollutants.

    Although, Air quality index is an informative tool to make citizens aware of the ambient air quality,its utility is restricted due to lack of actionable output. No advisories are generated on the basis of air quality, there are no built up mechanisms to regulate traffic or close schools in event of severe air quality.Thus, policies should be integrated with air quality index to make it more meaningful.
