1. Introduction

Air pollution is a pressing environmental issue in India, severely impacting public health, biodiversity, and the climate. The need for a specific legal mechanism led to the enactment of the Air (Prevention and Control of Pollution) Act, 1981, aimed at preventing, controlling, and reducing air pollution through administrative and legal interventions.

2. Historical Background

Following the 1972 Stockholm Conference on Human Environment, where India participated, environmental protection became a global concern. Recognising the need for focused legislation, the Government of India enacted the Air (Prevention and Control of Pollution) Act, 1981, using its power under Article 253 of the Constitution to implement international agreements.

3. Objectives of the Act

  • To provide for the prevention, control, and abatement of air pollution.
  • To maintain and restore the quality of air.
  • To establish Central and State Pollution Control Boards for effective implementation.
  • To set standards for emission from industrial plants and automobiles.

4. Key Definitions (Section 2)

Term Definition
Air Pollutant Any solid, liquid, or gaseous substance in the atmosphere in such concentration as may be injurious (Sec. 2(a))
Air Pollution The presence of any air pollutant in the atmosphere (Sec. 2(b))
Emission Any solid or liquid or gaseous substance coming out of any chimney, duct, etc. (Sec. 2(j))
Control Equipment Equipment designed to control the emission of air pollutants (Sec. 2(e))

5. Authorities under the Act

11. Conclusion

The Air (Prevention and Control of Pollution) Act, 1981 was a pioneering effort in India’s environmental legislation.
