Introduction – Background, Meaning and Legislative Purpose
The Air (Prevention and Control of Pollution) Act, 1981 was enacted to prevent, control, and abate air pollution in India and to maintain the quality of air necessary for healthy living. Rapid industrialization, urban growth, and increased use of motor vehicles led to a significant deterioration in air quality, posing serious threats to public health and the environment. Recognizing these challenges, Parliament enacted this law following India’s participation in the United Nations Conference on the Human Environment, Stockholm, 1972, reflecting the country’s commitment to international environmental standards.
The primary objective of the Act is to provide a statutory framework for controlling air pollution through preventive regulation rather than post-damage remedies. The Act focuses on regulating emissions, monitoring air quality, and empowering pollution control authorities to enforce environmental standards.
Scope and Key Concepts under the Act
The Act defines “air pollutant” under Section 2(a) as any solid, liquid, or gaseous substance, including noise, present in the atmosphere in such concentration as may be injurious to human beings, other living creatures, plants, property, or the environment. The inclusion of noise within the definition expands the scope of the Act beyond conventional air pollutants.
“Air pollution” under Section 2(b) refers to the presence of air pollutants in the atmosphere. An “industrial plant,” defined under Section 2(k), includes any plant used for industrial or trade purposes that emits air pollutants. These definitions enable the Act to regulate a wide range of pollution sources, including factories, power plants, and vehicular emissions.
Institutional Framework and Powers of Authorities
The Air Act relies on the institutional framework established under the Water Act. The Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) constituted under the Water Act are empowered to perform functions under the Air Act as well. Their responsibilities include planning programs for air pollution control, advising governments, laying down emission standards, and monitoring air quality.
Under Section 19, State Governments are authorized to declare any area as an Air Pollution Control Area, enabling stricter regulation of industrial activities within such zones. This provision allows targeted intervention in areas facing severe air pollution.
Consent Mechanism and Regulatory Controls
A crucial feature of the Air Act is the consent mechanism. Section 21 mandates that no industrial plant shall be established or operated in an air pollution control area without prior consent from the State Pollution Control Board. This requirement ensures that pollution control measures are incorporated before industrial operations commence.
The Act empowers Boards to impose conditions while granting consent, including emission standards and installation of pollution control devices. Non-compliance can result in withdrawal of consent, reflecting the preventive and regulatory nature of the legislation.

Prohibition, Enforcement and Monitoring
Section 22 prohibits the emission of air pollutants in excess of prescribed standards. To enforce this provision, Boards are empowered under Sections 26 and 28 to inspect industrial plants and take samples of air emissions. These technical procedures ensure that enforcement actions are based on scientific evidence.
In cases of serious pollution, authorities may issue directions under the Environment (Protection) Act, 1986, supplementing the enforcement powers of the Air Act.
Offences, Penalties and Legal Proceedings
The Act prescribes penalties for violations under Section 37, which may include imprisonment, fines, or both. Section 40 extends liability to individuals in charge of companies, ensuring corporate accountability. Courts may take cognizance of offences upon complaints filed by the Board or by individuals after giving prior notice under Section 43, enabling limited public participation in enforcement.
Judicial Interpretation and Constitutional Linkages
The judiciary has consistently linked air quality with the right to life under Article 21 of the Constitution. In M.C. Mehta v. Union of India (Vehicular Pollution Case), the Supreme Court issued extensive directions to reduce air pollution in Delhi, including the introduction of CNG vehicles. The Court recognized that clean air is an essential component of the right to life.
In A.P. Pollution Control Board v. Prof. M.V. Nayudu (1999), the Court emphasized the importance of scientific expertise in environmental regulation, reinforcing the need for effective implementation of pollution control laws such as the Air Act.
Recent Developments and Policy Measures
Recent years have witnessed increased judicial and administrative focus on air quality management, particularly in urban areas. Measures such as stricter emission norms, expansion of air quality monitoring networks, and implementation of national clean air programs reflect the continuing relevance of the Air Act in addressing contemporary environmental challenges.

Situation-Based Questions and Answers
If an industry operates in an air pollution control area without obtaining consent, action can be taken under Section 21, including closure. If emission standards are violated, penalties may be imposed under Section 37. Citizens affected by severe air pollution may approach constitutional courts under Article 21 for enforcement of their right to clean air.
