The Ministry of Environment, Forest and Climate Change (MoEFCC) will launch the ‘Swachh Vayu Sarvekshan’ programme under National Clean Air Programme 2019 (NCAP) to rank cities based on their actions to improve air quality.

• The ranking will be based only on the actions taken by the cities to improve the air quality in different domains and not on the measurement of the air quality parameters to rank the cities.
• At least 131 cities are categorised into three groups based on population. The first group has 47 cities with a population of over one million, and 44 cities in the second group have people between 300,000 to one million. The third group consists of 40 towns with less than 300,000 population.
