Air Pollution is an important environmental issue in India, affecting the public health, economic growth and the quality of life. Caused due to rapid industrialisation, urbanisation and vehicular emissions, the problem of air pollution has been out of control. In this article, we are going to cover all about Air Pollution in India and ways to control it.\u00a0<\/span><\/p>\r\n

Air Pollution<\/span><\/h2>\r\n

Air Pollution refers to the contamination of the atmosphere and the environment due to harmful substances that affect human health, ecosystems and the climate.\u00a0<\/span><\/p>\r\n

Air Pollution appears in the form of gases, solid particles and the combination of both.\u00a0<\/span><\/p>\r\n

Causes of air pollution include industries, vehicles, burning of fossil fuels and natural processes like dust storms.\u00a0<\/span><\/p>\r\n

Air pollution is one of the most serious forms of environmental pollution all over the world.\u00a0<\/span><\/p>\r\n

Air Pollution in India Severity<\/span><\/h2>\r\n

The deterioration in the quality of air in India has been an alarming issue in India for over two decades:\u00a0<\/span><\/p>\r\n

    \r\n\t
  • India is ranked as one of the most polluted countries all over the world, with high levels of particulate matter. (PM2.5)<\/span><\/li>\r\n\t
  • In 2021, about 97% of the population will have been exposed to PM2.5 levels exceeding WHO\u2019s air quality guidelines, putting people at risk for severe health problems.\u00a0<\/span><\/li>\r\n\t
  • Urban cities like Delhi and other metropolitan cities have constantly failed to meet the air quality standards.\u00a0<\/span><\/li>\r\n\t
  • Small towns and medium sized cities are also now a victim to rising levels of pollution.\u00a0<\/span><\/li>\r\n\t
  • Apart from the particulate matter, pollutants such as nitrogen oxides, sulfur dioxide and toxic compounds are contributing to the crisis.\u00a0<\/span><\/li>\r\n<\/ul>\r\n

    Air Pollution Effects<\/span><\/h2>\r\n

    Air Pollution in India has the following effect:\u00a0<\/span><\/p>\r\n

      \r\n\t
    • Health Impacts:\u00a0<\/b><\/li>\r\n<\/ul>\r\n
        \r\n\t
      • Causes respiratory diseases like asthma, bronchitis, and chronic obstructive pulmonary disease (COPD).<\/span><\/li>\r\n\t
      • Increases the risk of cardiovascular problems and premature deaths.<\/span><\/li>\r\n\t
      • According to the Health Effects Institute (2018), annual deaths from air pollution in India are projected to rise from 1.1 million in 2015 to 1.7 million in 2030.<\/span><\/li>\r\n<\/ul>\r\n

                    • Reduces labour productivity owing to illness-related absenteeism.<\/span><\/li>\r\n\t
                    • The annual economic cost of air pollution in India is estimated at over $150 billion.<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ol>\r\n

                      Air Pollution Controlling Measures\u00a0<\/span><\/h2>\r\n

                      In order to control air pollution, the Government of India has taken up the following measures:\u00a0<\/span><\/p>\r\n

                        \r\n\t
                      • The Air (Prevention and Control of Pollution) Act, 1981 provides a legal foundation for regulation of air pollution all over India.\u00a0<\/span><\/li>\r\n\t
                      • The Central Pollution Control Board (CPCB) and State Pollution Control Boards have the power to monitor and regulate air quality.\u00a0<\/span><\/li>\r\n\t
                      • The National Ambient Air Quality Standard provide permissible limits for 12 key pollutants, forming a basis for monitoring and compliance.\u00a0<\/span><\/li>\r\n\t
                      • Introduction of cleaner fuels like CNG, LPG and biodiesel.\u00a0<\/span><\/li>\r\n\t
                      • Setting up nationwide monitoring networks to assess ambient air quality.\u00a0<\/span><\/li>\r\n\t
                      • Enforcement of Bharat Stage VI (BS-VI) vehicle emission norms nationwide since 2020.<\/span><\/li>\r\n\t
                      • Adoption of common pollution control facilities to reduce industrial emissions.\u00a0<\/span><\/li>\r\n\t
                      • Promotion of green crackers and installation of Smog Towers in high-pollution zones.\u00a0<\/span><\/li>\r\n<\/ul>\r\n

                        Air Pollution Air Quality Index (AQI)<\/span><\/h2>\r\n

                        The Air Quality Index is a simple, colour coded system that provides people with accessible information on air quality. It uses a \u201cone number-one colour-one description\u201d model to make data easy to understand.\u00a0<\/span><\/p>\r\n

                          \r\n\t
                        • AQI covers eight pollutants: PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb.\u00a0<\/span><\/li>\r\n\t
                        • The quality of air is divided into six categories on the basis of pollutant concentration and health impact: Good, Satisfactory, Moderately Polluted, Poor, Very Poor, and Severe.<\/span><\/li>\r\n\t
                        • Each category indicates potential health risks, ranging from minimal effects to severe health impacts even on healthy individuals.<\/span><\/li>\r\n<\/ul>\r\n

                          National Clean Air Programme (NCAP)\u00a0<\/span><\/h2>\r\n

                          The National Clean Air Programme was launched in 2019, as a national strategy to fight against air pollution.\u00a0<\/span><\/p>\r\n

                            \r\n\t
                          • Aims to achieve a 20-30% reduction in PM levels by 2024. (2017 was base year)<\/span><\/li>\r\n\t
                          • Revised to aim for a 40% reduction by 2026.\u00a0<\/span><\/li>\r\n\t
                          • The key focus areas include strengthening monitoring networks, public awareness and capacity building.\u00a0\u00a0<\/span><\/li>\r\n<\/ul>\r\n

                            Air Pollution Institutional Measures: CAQM and CAP\u00a0<\/span><\/p>\r\n

                            The Commission for Air Quality Management was set up by the Air Quality Management in NCR and Adjoining Areas Act, 2021 to ensure balanced action in MCR and neighboring states.\u00a0<\/span><\/p>\r\n

                            Comprehensive Action Plan has been designed for Delhi-NCR to meet air quality standards through:\u00a0<\/span><\/p>\r\n

                              \r\n\t
                            • Time-bound targets for clean air.<\/span><\/li>\r\n\t

                            • Emergency response systems to reduce exposure during pollution peaks.<\/span><\/li>\r\n\t
                            • Addressing both seasonal sources (stubble burning, firecrackers) and consistent sources (vehicular and industrial emissions).<\/span><\/li>\r\n<\/ul>\r\n

                              Graded Response Action Plan (GRAP)\u00a0<\/span><\/h2>\r\n

                              GRAP was introduced in India in 2017 as an emergency response framework for Delhi-NCR<\/span><\/p>\r\n

                                \r\n\t
                              • It prescribes graded measures based on AQI levels (Moderate, Poor, Very Poor, Severe, and Severe+).<\/span><\/li>\r\n\t
                              • The plan ensured incremental actions, such as traffic restrictions, construction bans, and industrial shutdowns during severe pollution episodes.<\/span><\/li>\r\n\t
                              • Implementation requires coordination among 13 agencies across Delhi, Haryana, Uttar Pradesh, and Rajasthan.\u00a0<\/span><\/li>\r\n<\/ul>\r\n
