Air Act 1981 — Ecological Framework
Ecological Framework
The Air (Prevention and Control of Pollution) Act, 1981, is India's primary legislation for combating air pollution. Enacted in response to global environmental concerns post-Stockholm Conference 1972, and drawing strength from constitutional provisions like Article 48A and 51A(g), its core objective is to prevent, control, and abate air pollution.
The Act defines 'air pollutant' broadly to include any substance injurious to life or environment, and 'air pollution' as its presence in the atmosphere. It establishes a robust institutional framework, designating the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) as the key implementing agencies.
These Boards are empowered to advise governments, plan pollution control programs, set ambient air quality and emission standards, conduct research, and monitor air quality. A crucial regulatory tool is the 'consent mechanism', requiring industries to obtain consent from SPCBs to establish or operate, subject to compliance with emission standards and installation of pollution control equipment.
State Governments can declare 'air pollution control areas' to impose specific restrictions. The 1987 amendment significantly strengthened the Act by increasing penalties and granting Boards direct powers, including closure of defaulting industries.
While facing challenges in enforcement and scope, the Act remains a cornerstone of India's environmental law, complemented by other legislations like the Environment (Protection) Act, 1986, and enforced by bodies like the National Green Tribunal.
Recent initiatives like the National Clean Air Programme and stricter BS-VI norms further reinforce its objectives.
