On 6 June 2026, the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) reported that its 132nd Enforcement Task Force (ETF) meeting had reviewed 245 inspections carried out by its Flying Squads across the National Capital Region (NCR) between 11 and 29 May 2026. The breakdown is granular: 31 inspections at construction & demolition (C&D) sites, 74 in the industrial sector and 140 of diesel-generator (DG) sets, turning up 87 violations and triggering closures, sealings and Environmental Compensation orders. It reads like a routine compliance bulletin — but it is a window into one of the most important pieces of environmental governance machinery in India, and a high-yield topic for CDS and OTA aspirants who study the environment.
Why Delhi-NCR has an air-quality "authority" at all
Delhi consistently ranks among the world's most polluted capitals, especially in winter (October–January), when a toxic mix builds up: vehicular exhaust, industrial emissions, road and construction dust, stubble (parali) burning in neighbouring Punjab and Haryana, firecrackers, and — critically — adverse meteorology. Cold air, low wind speed and temperature inversion (a layer of warm air trapping cooler, polluted air near the ground) prevent pollutants from dispersing. Because air does not respect state borders, the pollution is an airshed problem spanning Delhi, Haryana, Uttar Pradesh, Rajasthan and Punjab. Tackling it needs a body that can coordinate across states — which is exactly the gap CAQM was created to fill.
CAQM: the statutory body explained
The Commission for Air Quality Management is a statutory body established under the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021. Two features make it powerful and exam-worthy:
- It replaced the Environment Pollution (Prevention and Control) Authority (EPCA), the Supreme Court-appointed body that earlier handled NCR air quality. CAQM is a permanent, statutory authority — stronger than the ad-hoc EPCA.
- It has overriding powers: where its directions conflict with those of state pollution control boards, CAQM's orders prevail, and it can impose penalties (including imprisonment and fines) for non-compliance. This single, empowered coordinator can issue binding directions across the whole NCR airshed — solving the multi-state coordination problem.
Note the distinction examiners probe: CAQM is statutory (created by an Act of Parliament), unlike a constitutional body (named in the Constitution) or an executive body (created by a government order). The same family includes other statutory environmental bodies such as the Central Pollution Control Board (CPCB) and the National Green Tribunal (NGT) — a useful cluster to revise together with statutory commissions and bodies.
GRAP: the graded emergency-response plan
CAQM's most famous tool is the Graded Response Action Plan (GRAP) — a set of emergency anti-pollution measures that switch on automatically as air quality worsens, calibrated to the Air Quality Index (AQI). GRAP has four stages, and you should memorise the AQI bands:
- Stage I — "Poor" (AQI 201–300): ban on visibly polluting vehicles, dust control at construction sites, action against open burning.
- Stage II — "Very Poor" (AQI 301–400): intensified dust control, restrictions on diesel generators, higher parking fees to discourage private vehicles, more public transport.
- Stage III — "Severe" (AQI 401–450): ban on most construction & demolition, restrictions on certain BS-III/IV vehicles, possible school closures for younger classes.
- Stage IV — "Severe+" (AQI above 450): entry bans on polluting trucks, halt to most construction, work-from-home advisories, and the strictest curbs.
GRAP was first notified in 2017 (implemented then by the EPCA) and is now run by CAQM. The genius of "graded" response is that measures are proportionate — the economy is not shut down prematurely, but curbs escalate automatically as the air turns dangerous.
Understanding the Air Quality Index
The Air Quality Index (AQI), launched in India in 2014 under the "Swachh Bharat–Swachh Hawa" banner, converts the concentrations of major pollutants into a single, easy-to-read number from 0 to 500, across six categories: Good (0–50), Satisfactory (51–100), Moderate (101–200), Poor (201–300), Very Poor (301–400) and Severe (401–500). It tracks eight pollutants, the most health-critical being PM2.5 and PM10 (fine and coarse particulate matter). PM2.5 — particles smaller than 2.5 microns — is especially dangerous because it penetrates deep into the lungs and bloodstream. AQI is what triggers each GRAP stage, so the two concepts must be revised together.
The enforcement story in this release
The 6 June 2026 report shows CAQM's enforcement arm at work outside the crisis season. Its Flying Squads conducted 245 inspections in 19 days, found 87 violations, and proposed closure of 11 units/projects, sealing of 33 DG sets, 19 compliance directions and Environmental Compensation in 13 cases. It also issued 18 resumption orders to units that had since complied. The takeaway: CAQM is not merely an advisory or seasonal body — it runs year-round, on-ground enforcement with real teeth, which is precisely what earlier mechanisms lacked.
Tackling the sources: what is actually being done
Enforcement is only one half; source reduction is the other. On stubble burning, the government promotes in-situ management (the Pusa bio-decomposer, a microbial spray developed by ICAR-IARI that rots crop residue into the soil) and ex-situ use of paddy straw as biomass fuel and in industry, backed by subsidies on Crop Residue Management (CRM) machinery. On vehicles, the leap from Bharat Stage IV to Bharat Stage VI (BS-VI) emission norms in April 2020 sharply cut permissible pollutants, and the push for electric vehicles and cleaner public transport (Delhi's CNG bus fleet and expanding Metro) attacks tailpipe emissions. On industry, NCR units have been steered towards piped natural gas (PNG) and away from coal/pet-coke, while dust-control norms target construction sites. CAQM's job is to coordinate, monitor and enforce this whole bundle across state lines — which is why its year-round inspection data matters.
The human and economic cost
Why invest so much machinery in air? Because the stakes are enormous. Air pollution is consistently ranked among the leading risk factors for premature death in India, contributing to respiratory illness, heart disease, stroke and reduced life expectancy — with children, the elderly and outdoor workers worst affected. Beyond health, polluted air imposes a real economic cost through lost workdays, higher healthcare spending and reduced productivity, and it dents India's image during the peak winter smog. Framing CAQM's work as a public-health and economic imperative — not just an environmental nicety — is exactly the mature angle that lifts an exam answer or an SSB discussion above rote recall.
The bigger environmental-governance picture
Place CAQM in the family of laws and bodies you must know for the environment paper: the Air (Prevention and Control of Pollution) Act, 1981; the Environment (Protection) Act, 1986 (the umbrella law passed after the 1984 Bhopal gas tragedy); the CPCB and State Pollution Control Boards; and the NGT (2010) for adjudication. CAQM, with its statutory backing and overriding powers, is the specialised, regional escalation of this architecture for India's most pollution-stressed airshed. The deeper lesson for an essay: pollution is a public-health and economic problem — it shortens lives, raises healthcare costs and dents productivity — so a permanent, coordinated, data-driven enforcement body is not bureaucratic excess but a genuine governance necessity.
