Delhi Chief Minister Rekha Gupta on 2 July 2026 announced the activation of a comprehensive 'Winter Pollution Master Plan' to combat the capital's annual winter air-quality crisis, with measures running from 1 November through 28 February.

What the plan mandates

The plan enforces a strict 'No PUC, No Fuel' rule, barring vehicles without a valid Pollution Under Control certificate from obtaining fuel at petrol stations. Entry of out-of-state vehicles below the BS-VI emission standard into Delhi will be prohibited during the period, a measure aimed at curbing vehicular pollution that accounts for a significant share of the city's particulate load.

On days when air quality deteriorates sharply, up to 50 per cent of government employees may be asked to work from home. Parking fees will be raised to discourage private vehicle use, with the revenue expected to support expansion of public transport.

All large construction sites will be required to install Anti-Smog and Mist Systems, and construction activity will face additional restrictions as conditions demand. Open burning of waste, leaves, and biomass — a persistent source of localised pollution — will be completely prohibited. Drone-based surveillance will monitor compliance, with strict action promised against violators.

Context

Delhi has recorded hazardous Air Quality Index levels every winter for over a decade. The mix of local vehicular and industrial emissions, construction dust, crop-residue burning in neighbouring states, and cold-weather meteorology that traps pollutants close to the ground makes October-to-February the most dangerous air-quality period for the capital's roughly 20 million residents.

The Graded Response Action Plan (GRAP), introduced in 2017, established a stage-wise emergency framework for the Delhi-NCR region. The Commission for Air Quality Management (CAQM), created by ordinance in 2020 and enacted into law in 2021, coordinates pollution control across Delhi and neighbouring states. Delhi governments have issued annual winter action plans since 2018, each layering fresh restrictions on to the GRAP architecture.

Policy backdrop

The Winter Pollution Master Plan announced by CM Rekha Gupta sits within this established regulatory ecosystem. The Supreme Court and the National Green Tribunal have repeatedly issued directions for coordinated action across the NCR, pushing successive administrations to move earlier in the calendar year rather than react only after AQI spikes. Announcing the framework in July — well before the October onset of the pollution season — signals an intent to give agencies, construction firms, and transport operators advance notice to prepare.

The vehicle-entry restriction targeting sub-BS-VI trucks and buses builds on earlier GRAP provisions that have historically been activated only after AQI crosses specified thresholds. Making the restriction a standing rule from 1 November removes the reactive lag that has drawn criticism in past seasons.

Stakeholders and impact

Delhi residents, particularly those with respiratory conditions, stand to benefit most if enforcement is sustained. Vehicle owners and interstate transport operators will need to upgrade or reroute fleets ahead of the November deadline. Construction firms running large sites face mandatory capital expenditure on anti-smog equipment. Farmers in Punjab and Haryana, whose paddy-stubble burning contributes to Delhi's winter smog, fall outside the direct jurisdiction of this plan but remain central to any durable solution.

What's next

Attention will turn to the CAQM and the Central Pollution Control Board (CPCB), which trigger formal GRAP stages once AQI crosses defined thresholds in October-November. Coordination meetings with Punjab and Haryana on farm-fire suppression will be critical to determining whether ground-level air quality actually improves. The effectiveness of drone surveillance and the speed of penalty enforcement will be early tests of whether this year's plan translates from announcement to action.
