In 2019, India launched 'The National Clean Air Programme' with tentative national target of 20%-30% reduction in PM2.5 and PM10 concentrations by 2024, considering 2017 as the base year for comparison. It will be rolled out in 102 cities that are considered to have air quality worse than the National Ambient Air Quality Standards. [15]
Ambient air quality criteria, or standards, are concentrations of pollutants in the air, and typically refer to outdoor air.The criteria are specified for a variety of reasons including for the protection of human health, buildings, crops, vegetation, ecosystems, as well as for planning and other purposes.

The emission standards for thermal power plants in India are being enforced based on Environment (Protection) Act, 1986 of Government of India and its amendments from time to time. [21] A summary of emission norms for coal- and gas-based thermal power plants is given in Tables 15 and 16.
The primary legislation governing air quality in India is the Air (Prevention and Control of Pollution) Act, 1981. [26] Additionally, the government introduced the National Clean Air Programme (NCAP) in 2019, aiming to reduce particulate matter (PM) pollution by 20-30% in at least 102 cities by 2024.
Functions of CPCB comes under both national level and as State Boards for the Union Territories. CPCB, under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, aims to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and to improve the quality ...
The Clean Air Act requires the EPA to set US National Ambient Air Quality Standards (NAAQS) for the six CAPs. [6] The NAAQS are health based and the EPA sets two types of standards: primary and secondary. The primary standards are designed to protect the health of 'sensitive' populations such as asthmatics, children, and the elderly.
Air quality or ambient/outdoor air pollution is represented by the annual mean concentration of particulate matter PM 10 (particles smaller than 10 microns) and PM 2.5 (particles smaller than 2.5 microns, about 25 to 100 times thinner than a human hair).
