National Clean Air Campaign

Context: Four years since the Centre launched the National Clean Air Campaign (NCAP), analysts found that progress has been slow and pollution only incrementally reduced in most cities.

About National Clean Air Campaign:

• It was launched by the Ministry of Environment Forest and Climate Change in January 2019.
• It is the first-ever effort in the country to frame a national framework for air quality management with a time-bound reduction target.
• It seeks to cut the concentration of coarse (particulate matter of diameter 10 micrometre or less, or PM10) and fine particles (particulate matter of diameter 2.5 micrometre or less, or PM2.5) by at least 20% in the next five years, with 2017 as the base year for comparison.
• The plan includes 103 non-attainment cities, across 23 states and Union territories, which were identified by the Central Pollution Control Board (CPCB) on the basis of their ambient air quality data between 2011 and 2015.
• Non-attainment cities: These are those that have fallen short of the National Ambient Air Quality Standards (NAAQS) for over five years.

About National Ambient Air Quality Standards (NAAQS):

• National Ambient Air Quality Standards are the standards for ambient air quality set by the Central Pollution Control Board (CPCB).
• The CPCB has been conferred this power by the Air (Prevention and Control of Pollution) Act, 1981.
• Ambient Air Quality Standards contains 12 pollutants.
• The pollutants that are covered under the NAAQS include: Sulphur dioxide (SO2), Nitrogen dioxide (NO2), PM10, PM2.5, Ozone, Lead, Carbon monoxide (CO), Arsenic, Nickel, Benzene, Ammonia, and Benzopyrene.

About Central Pollution Control Board (CPCB):

• The Central Pollution Control Board (CPCB), statutory organisation, was constituted under the Water (Prevention and Control of Pollution) Act, 1974.
• Further, CPCB was entrusted with the powers and functions under the Air (Prevention and Control of Pollution) Act, 1981.
• It serves as a field formation and also provides technical services to the Ministry of Environment and Forests of the provisions of the Environment (Protection) Act, 1986.
• Principal Functions of the CPCB, as spelt out in the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981,
  • 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 of air and to prevent, control or abate air pollution in the country.
• The National Air Monitoring Programme (NAMP) has been established with objectives to determine the present air quality status and trends and to control and regulate pollution from industries and other source to meet the air quality standards. It also provides background air quality data needed for industrial siting and towns planning.
