The Ministry of Urban Development, Government of India, and the Central Pollution Control Board (CPCB) of India, annually publish National City Rating under the Swachh Bharat Abhiyan scheme. The rating includes around 500 cities, covering 72 percent of the urban population in India.

Until 2017, India was divided into five zones for the purpose of this survey and each city was scored on 19 indicators. The cities were classified into four colours: green, blue, black, and red, green being the cleanest city, and red the most polluted. None of the cities was rated as green—the best category in the exercise. However, during the 2017-18 senses survey, the parameters of assessment were modified, and cities were categorised, based on population, into metropolis, large, medium, and small cities, and assessment took place according to this categorisation.^[1]
