In an effort to tackle the menace of air pollution, Prime Minister Narendra Modi will today launch the first national air quality index in ten cities across the country.

The index will inform the public about the level of pollution in the air on a daily basis in real-time. The AQI is a global standard used to understand air quality. It takes various parameters available in our national air quality standard and presents it as a cumulative on a 6 colour coded scale. Dark green denotes the cleanest and maroon denotes the most polluted.

A World Health Organization study shows that 13 Indian cities figure among the 20 most polluted cities of the world. The project's aim is also to enhance public awareness and involvement in efforts to improve air quality.

According to environment minister Prakash Javadekar, the service will be expanded to 46 cities with a population of 1 million or more each and 20 state capitals in the next couple of years.
