Delhi Dust Pollution 2026: MRSM, CAQM, Art 21 for CLAT 2027

CURRENT AFFAIRS | 26 MAY 2026

An Indian Express editorial has flagged that Delhi’s Mechanical Road Sweeping Machine (MRSM) fleet remains severely underutilised — even as dust accounts for ~41% of PM10 and ~38% of PM2.5 in the capital’s summer air. The piece calls for a coordinated dust-management strategy, foregrounding the legal and constitutional scaffolding around the right to clean air.

Constitutional & Statutory Framework

  • Article 21Subhash Kumar v. State of Bihar (1991) — Right to pollution-free air and water is part of the right to life.
  • Article 48A (DPSP) and Article 51A(g) (Fundamental Duty) — Direct the State and citizens to protect and improve the environment.
  • Air (Prevention and Control of Pollution) Act, 1981 — Constituted Central and State Pollution Control Boards; declares ‘air pollution control areas’.
  • Environment (Protection) Act, 1986 — Umbrella enabling legislation enacted post-Bhopal; empowers Centre to set emission standards.
  • CAQM Act, 2021 — Created the Commission for Air Quality Management in NCR & Adjoining Areas; replaces EPCA.
  • National Green Tribunal Act, 2010 — Created the NGT; principal bench in New Delhi.

  • NCAP — National Clean Air Programme, launched 2019; target: 40% reduction in PM2.5 and PM10 levels by 2026 (revised from 2024).
  • GRAP — Graded Response Action Plan, four stages activated by AQI bands; administered by CAQM.

Mnemonic — ‘A-E-C-N-G governs Delhi’s air’

Air Act 1981 → Environment Act 1986 → CAQM Act 2021 → NCAP 2019 → GRAP (graded response). Cross-link to Art. 21 (Subhash Kumar) + Art. 48A + Art. 51A(g) — the constitutional-statutory loop on the right to clean air.

Save this for revision — air pollution is a CLAT favourite, especially in October-November set papers.
