Every year, as winter approaches, Delhi slips into a familiar cycle of thick smog, deteriorating air quality and long queues at clinics and hospitals. Patients across age groups seek medical attention for breathing difficulties, as the capital’s winter air is often compared to smoking 20 cigarettes a day.
With pollution levels becoming a recurring concern, the Delhi government has announced a fresh set of stringent measures, scheduled to come into effect from November 1.
Delhi Government’s Pollution Fight: What’s Changing?
The new measures aim to tackle vehicular emissions, dust pollution and congestion through stricter enforcement and changes to everyday routines.
- Restrictions on commercial vehicles: A complete ban on non-BS-VI commercial vehicles entering Delhi from neighbouring states.
- Mandatory PUC checks: No fuel will be dispensed to vehicles without a valid Pollution Under Control (PUC) certificate.
- Work-from-home policy: Government and private offices have been directed to implement a 50% work-from-home policy.
- Higher parking fees: Parking fees at municipal and commercial parking lots are set to double.
- AI and drone surveillance: AI-enabled video and drone monitoring systems are set to be deployed at construction and demolition sites to penalise dust-compliance failures.
- Construction restrictions: Construction work and demolition activities are banned until the end of January.
How Bad Is Delhi’s Air Pollution?
Delhi’s Air Quality Index (AQI) currently falls in the ‘poor’ category, with readings between 201 and 300. At these levels, people may experience respiratory discomfort, reduced exercise tolerance and eye irritation, while vulnerable groups, including children and the elderly, may experience worsening symptoms.
Graded Response Action Plan (GRAP) Stage I restrictions have come into force. These include mechanical road sweeping, water sprinkling, regular removal of municipal solid waste and construction debris, a strict ban on open garbage burning, and mandatory dust-mitigation measures at construction sites.
How Have Delhi’s Pollution-Control Measures Evolved?
A comparison with the 2025 protocols points to some notable changes in this year’s approach.
Last year’s measures primarily focused on preventing garbage burning, mechanical sweeping, water sprinkling and PUC checks. This year, restrictions on diesel generators have been introduced right from GRAP Stage I. Meanwhile, restrictions on BS-IV diesel and petrol buses have been moved from Stage I to Stage II, alongside 25 new action metrics targeting dust and municipal solid waste management.
The strategy also shifts as air quality deteriorates. When the AQI enters the ‘very poor’ category of 300–400, the focus moves towards more targeted interventions. While last year’s approach emphasised vacuum sweeping along traffic corridors and action at pollution hotspots, this year’s strategy places greater emphasis on localised congestion management and strict enforcement against vehicle idling at high-density traffic intersections.

Will Stricter Enforcement Make a Difference?
Delhi’s latest pollution-control measures signal a push towards tighter monitoring, stricter compliance and more targeted interventions. From restrictions on vehicle entry and fuel dispensing to workplace changes and surveillance at construction sites, the measures seek to address multiple sources of pollution.
But as winter sets in, the real test will be implementation. For Delhi’s residents, the question remains, whether these sharper enforcement tools will finally make a tangible difference and clear the capital’s suffocating, smoke-filled skies.
