Inspections, challans, refusals of entry: the Supreme Court has sought NCR vehicle-emission enforcement data from Delhi authorities and neighbouring States. Its November 6 order also requires specific proposals and a time-bound roadmap to strengthen enforcement, while fixing separate hearings on different sources of NCR air pollution.

New Delhi: Before the next hearing in its continuing NCR air-pollution proceedings, the Municipal Corporation of Delhi, the Delhi government, Delhi Police’s Traffic Department and the governments of Haryana, Rajasthan and Uttar Pradesh must file detailed responses on vehicle-emission enforcement, the Supreme Court has directed.
The order was passed on November 6, 2026 by a bench of Chief Justice Surya Kant and Justices Joymalya Bagchi and V. Mohana and uploaded on November 8. It seeks enforcement data and proposed action in a pending case; it does not finally dispose of the pollution proceedings.
Five hearings, one lead matter
The Court fixed November 23 for vehicular emissions, November 25 for solid-waste management and the burning of crop residue and firecrackers, November 26 for construction activity, power plants and other industries, and November 30 for conservation and enhancement of green cover. These hearings concern Suo Motu Writ Petitions (Civil) Nos. 12, 15, 14 and 13 of 2026, respectively.
The present petition, No. 11 of 2026, will remain the lead matter and be listed on each date. The amici were requested to submit short notes at least two days before the relevant hearing.
According to the order, five separate proceedings were registered after the March 12, 2026 judgment in W.P.(C) No. 13029/1985, each to address a different aspect of NCR air pollution. That restructuring reshaped the earlier proceedings rather than bringing them to a close.
What the authorities must put on record
Paragraph 7 asks the authorities to describe the rules and enforcement mechanisms governing commercial and non-commercial vehicles entering and travelling within Delhi and the NCR, particularly vehicles coming from neighbouring States.
Each response must explain how vehicles failing prescribed emission standards are identified, monitored and regulated, including enforcement of Pollution Under Control (PUC) certification. Details are also sought of steps to prevent the entry and operation of over-age, end-of-life and otherwise non-compliant vehicles.
Concrete figures are required: how many vehicles were inspected, challaned, denied entry or otherwise proceeded against during the relevant period. The bench also asked how Delhi and neighbouring States coordinate inter-State vehicle movement and compliance with emission norms.
Besides existing measures, the authorities must set out proposed short-term and long-term steps to reduce vehicular pollution. The order specifically requires measures to strengthen enforcement, along with a time-bound implementation roadmap.
Compliance reports and the vehicle surge
Additional Solicitor General Aishwarya Bhati, appearing for the Union and the Commission for Air Quality Management (CAQM), highlighted measures concerning vehicular emissions and stubble burning. The amici curiae pointed out, however, that compliance with earlier orders, particularly those dated January 21 and February 23, 2026, had not been properly reported.
The amici placed a graphical presentation of compliance with the Graded Response Action Plan for October 21 to November 3, 2026. The Court recorded that the data indicated a substantial decline in stubble-burning incidents across Delhi, Uttar Pradesh, Haryana and Rajasthan, while also showing a sharp increase in issues attributable to vehicular emissions.
The bench emphasised that Delhi and the NCR bear the cumulative burden of traffic from across the region, and referred to the volume of both commercial and non-commercial vehicles entering the city from neighbouring States.
In paragraph 4, the Court gave the States two weeks to place their submissions on record. These must address steps already taken, their responses to suggestions made by CAQM and the amici, and any further action they independently propose.
