Why in News

  • The world observed the International Day of Clean Air for Blue Skies on 7 September to raise awareness and encourage global action against air pollution.
  • The United Nations General Assembly established this annual event in 2019 to emphasize international commitments toward improving air quality.
  • India celebrates this day as Swachh Vayu Diwas to align its national pollution control goals with international efforts.

What is Air Pollution

  • Air pollution occurs when harmful gases, liquid droplets, or solid particles accumulate in the atmosphere at dangerous levels.
  • These pollutants originate from natural events as well as human activities like vehicle transport, manufacturing, construction, and open burning.
  • Clean air remains essential for maintaining human health, protecting ecosystems, and sustaining economic prosperity.
  • Particulate Matter consists of tiny solid or liquid particles floating in the air that pose severe health risks.
  • The category PM10 includes all coarse particles with a diameter measuring 10 micrometres or less.
  • The category PM2.5 consists of fine particles measuring 2.5 micrometres or less that can enter deep into the human lungs and blood circulation.
  • Because of their tiny size, PM2.5 particles cause severe heart and lung diseases, making particle reduction a vital public health goal.

Air Pollution Monitoring Systems

  • The Continuous Ambient Air Quality Monitoring System (CAAQMS) provides real-time automated tracking of major air pollutants including PM2.5, PM10, SO2, NOx, CO, O3, and NH3.
  • The Ambient Air Quality Monitoring System (AAQMS) uses both manual 24-hour sample testing and automated continuous measurements to track air quality.
  • The Online Continuous Emission Monitoring System (OCEMS) requires highly polluting industrial plants to send real-time emission data straight to regulatory authorities.

National Air Quality Monitoring Programme (NAMP)

  • The Central Pollution Control Board (CPCB) started the NAMP initiative to track air quality trends, identify policy violations, and evaluate public health risks.
  • As of March 2026, the country operates 1,646 monitoring stations spread across 603 cities in 28 States and 7 Union Territories.
  • This tracking network uses manual sampling stations alongside real-time continuous monitoring stations.
  • Citizens can check real-time air quality data for over 292 cities using the SAMEER mobile app and report local pollution complaints.

Air Quality Index (AQI)

  • The Air Quality Index (AQI) transforms complex chemical data into a simple color-coded scale to inform the public about air safety.
  • Calculations for the AQI monitor eight key pollutants: PM2.5, PM10, Nitrogen Dioxide, Sulphur Dioxide, Carbon Monoxide, Ozone, Ammonia, and Lead.
  • An AQI score between 0 and 50 indicates Good air, while 51 to 100 represents Satisfactory conditions.
  • An AQI level between 101 and 200 means Moderate pollution, whereas 201 to 300 signals Poor air quality.
  • An AQI reading of 301 to 400 represents Very Poor air, and any score from 401 to 500 marks Severe air pollution.

National Clean Air Programme (NCAP)

  • The Ministry launched the National Clean Air Programme (NCAP) in 2019 as a targeted initiative covering 130 cities.
  • This program drives source-specific pollution control plans created through cooperation between central ministries, state leaders, and local city bodies.
  • A total of 24 States and UTs together with 130 target cities have finalized customized clean-air strategies.
  • Between FY 2019-20 and FY 2025-26, the government released Rs 16,423.55 crore in performance grants, with cities spending Rs 11,575.54 crore (70.5%) so far.
  • During FY 2025-26, 108 cities successfully lowered their annual average PM10 levels compared to 2017-18 baseline levels.
