Delhi and its surrounding cities have some of the worst air quality in the world. But beneath the headlines about winter smog spikes, a steadier, less-glamorous enforcement machine has been grinding away — and the numbers it is now producing reveal just how entrenched the sources of pollution remain.

The Commission for Air Quality Management in NCR and Adjoining Areas (CAQM), the statutory body responsible for clean air across Delhi, Haryana, Uttar Pradesh, Rajasthan, and Punjab, held its 134th Enforcement Task Force (ETF) meeting on July 6, 2026. The update it released gives a rare, concrete look at where the pollution is coming from — and what is being done about it.

What the Flying Squads Found

CAQM’s Flying Squads conducted 173 inspections between June 14 and June 30, 2026. Of those, 62 turned up violations — a 36% violation rate that reflects the difficulty of achieving compliance across a sprawling, industrialised region.

The breakdown is telling. Of the 62 violations found, 31 were in the industrial sector and 24 were related to diesel generator (DG) sets. Construction and demolition sites accounted for just 7. The industrial and DG set numbers are consistent with what CAQM has been finding through 2026 — in an earlier reporting period from May, 87 violations were found across 245 inspections, with DG sets again the leading offender category.

The remedies proposed in this round include closure of 4 units or projects, sealing of 27 DG sets, and the imposition of Environmental Compensation (a financial penalty) in 17 cases. DG sets — large diesel generators used as backup power by factories, offices, and commercial buildings — are a major and chronically under-regulated source of particulate matter and nitrogen oxides in the NCR.

The Cumulative Picture

Since CAQM’s Flying Squads began their enforcement drives, the commission has inspected 27,750 entities across the NCR. Of 1,802 Closure Directions issued to date, 1,424 Resumption Orders have been granted — meaning the unit demonstrated compliance and was allowed to restart. That leaves a significant tail of entities still under examination or facing closure, pointing to the scale of the enforcement challenge.

Beyond the inspection programme, CAQM has been tightening the regulatory environment across the board in 2026. A new rule — “No PUC, No Fuel” — comes into force across the entire NCR from October 1, 2026, requiring all vehicles to present a valid Pollution Under Control Certificate before being able to purchase petrol or diesel. The sustainable transport implications are significant: the rule is expected to bring millions of older, poorly-maintained vehicles into the compliance net or off the road.

Industrial emissions standards are also tightening. Large and medium industries will face a stricter particulate matter limit of 50 mg/Nm³ from August 1, and all industries from October 1.

Why This Matters Beyond Delhi

Air environment sustainability in the Indo-Gangetic Plain is one of India’s most urgent public health challenges. The NCR’s annual average AQI target for 2026 is a 15% reduction from the five-year average — an ambitious goal that requires sustained enforcement rather than seasonal crisis response.

CAQM’s work is often overshadowed by the dramatic GRAP (Graded Response Action Plan) orders that dominate winter news cycles. But the Flying Squads and ETF meetings happening year-round are arguably more important — they are the mechanism through which baseline pollution from factories, generators, and construction sites gets held to account between the headline crises.

For anyone who cares about carbon reduction and clean air as a quality-of-life issue, the slow, methodical work of 173 inspections and 62 penalty notices may be less satisfying than a dramatic policy announcement — but it is exactly the kind of structural accountability that makes long-term improvement possible.
