Court Orders on Air Pollution Control Measures

Air pollution has emerged as a critical health and environmental crisis in India.
Over the past decade, Indian courts — particularly the Supreme Court and the National Green Tribunal (NGT) — have issued several strong directives to control and mitigate air pollution, especially in urban centers like Delhi-NCR.

Legal Framework Involved

  • Air (Prevention and Control of Pollution) Act, 1981:
    • The primary legislation for preventing, controlling, and abating air pollution.
       
  • Environment (Protection) Act, 1986:
    • Provides broad powers to the central government for environmental protection, including air quality regulation.
       
  • Constitution of India:
    • Article 21: Right to life includes the right to a healthy environment.
    • Article 48A: Mandates the State to protect and improve the environment.
    • Article 51A(g): Imposes a duty on citizens to protect the natural environment.

Major Court Orders on Air Pollution

1. M.C. Mehta v. Union of India (Delhi Air Pollution Cases)

  • The Supreme Court directed the conversion of all commercial vehicles in Delhi to CNG.
  • Banned overaged commercial vehicles and restricted industrial activities contributing to air pollution.
  • Led to the creation of the Environment Pollution (Prevention and Control) Authority (EPCA) under Section 3 of the Environment Protection Act, 1986.

2. Ban on Firecrackers

  • The Supreme Court in 2018 restricted the sale and use of traditional firecrackers.
  • Introduced the concept of "green crackers" to reduce emissions.
  • Time slots for bursting crackers were strictly regulated.

3. Stubble Burning Crisis

  • In 2020, the Supreme Court took suo motu cognizance of stubble burning in Punjab, Haryana, and Uttar Pradesh.
  • Directed state governments to take immediate action to curb farm fires.
  • Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021 was enacted as a response.

4. Odd-Even Scheme Validation

  • The Delhi government’s odd-even vehicle scheme was challenged but upheld by courts as a reasonable restriction under Article 19(2) of the Constitution to control air pollution.

Key Directives by the National Green Tribunal (NGT)

  • Closure of Polluting Industries:
    • NGT has regularly ordered closure or heavy fines on industries operating without valid consent under the Air Act.
       
  • Dust Control Measures:
    • Construction sites must implement dust suppression measures.
       
  • Ban on Diesel Vehicles:
    • Diesel vehicles over 10 years old were banned in Delhi-NCR.
       
  • Penalty for Waste Burning:
    • Open burning of waste materials like plastic and rubber is strictly prohibited.

Challenges in Implementation

1. Lack of Coordination

  • Despite multiple court directives, poor coordination between central, state, and local authorities hampers enforcement.

2. Weak Monitoring Mechanisms

  • Real-time monitoring of air quality measures is still inconsistent across many cities.

3. Public Non-Compliance

  • Despite awareness campaigns, public compliance with restrictions (like burning waste or excessive vehicle use) remains low.

Recent Developments

  • Graded Response Action Plan (GRAP):
    • Implemented seasonally in Delhi-NCR based on pollution levels.
       
  • Commission for Air Quality Management:
    • Established in 2021 for better coordination and implementation of pollution control measures in NCR and adjoining areas.
       
  • Push for Electric Vehicles (EVs):
    • Courts have encouraged both governments and private sectors to shift towards EVs to reduce vehicular emissions.

Conclusion

The judiciary has played a proactive and powerful role in pushing governments and citizens towards better air quality standards.
However, strong legal orders must be matched by effective, on-ground implementation to achieve lasting improvements.
Protecting the fundamental right to a clean environment requires not just judicial activism but also administrative efficiency and public participation.
