In a significant move to combat air pollution in the National Capital Region (NCR), the Commission for Air Quality Management (CAQM) has announced a sweeping ban on all non-BS VI diesel-powered transport and commercial goods vehicles entering Delhi starting July 1, 2025. This bold step is part of a larger phased plan that will eventually cover the entire NCR.

Phased Ban Across NCR

While Delhi will implement the ban from July 1, similar restrictions will apply to Gurgaon, Faridabad, Ghaziabad, Gautam Budh Nagar, and Sonipat from November 1, 2025. The final phase will enforce the restriction across all remaining NCR districts from April 1, 2026. This phased rollout allows logistics companies and transport operators time to adapt to the new requirements.

Exemptions and Compliance Timelines

Vehicles registered in Delhi are currently exempt from the ban. However, temporary exemptions have been made for non-BS VI vehicles transporting essential goods or offering emergency services — valid only until October 31, 2026. Post that, even these vehicles must comply with the cleaner fuel norms or face penalties.

Targeting Major Polluters

The CAQM directive primarily focuses on diesel vehicles that fail to meet BS-VI standards, given their high emission levels. Permissible vehicle types under the new regime include those powered by BS-VI diesel, CNG, LNG, or electric power, encompassing Light Goods Vehicles (LGVs), Medium Goods Vehicles (MGVs), and Heavy Goods Vehicles (HGVs).

Surveillance and Enforcement at Entry Points

To ensure strict enforcement, the Delhi government is deploying Automatic Number Plate Recognition (ANPR) cameras at all 126 border entry points and 52 toll plazas. These high-tech systems will automatically identify and log vehicles based on compliance status.

According to Delhi’s Environment Minister Manjinder Singh Sirsa, 95% of the ANPR camera installations have already been completed, and additional infrastructure upgrades are underway.

Urgency Amid Rising Pollution

The directive comes in the wake of Delhi’s consistent struggle with dangerous air quality levels, especially during winter months. Commercial transport vehicles have been flagged as one of the top contributors to vehicular pollution in the region, prompting regulatory bodies to adopt aggressive curbing strategies.

Role of Transport Departments and Police

The CAQM has asked transport departments and traffic police in Delhi and neighbouring states to strictly enforce the ban. They are expected to actively monitor vehicle entries, penalize violators, and assist in identifying end-of-life or overaged vehicles.

Importance of the BS-VI Standard

Introduced in 2020, the Bharat Stage VI (BS-VI) emission norms represent India’s most stringent vehicle pollution standards. Compared to BS-IV, BS-VI vehicles emit significantly lower nitrogen oxides, hydrocarbons, and particulate matter.

Push Towards Cleaner Alternatives

The move aligns with India's broader push for sustainable transport and AatmaNirbhar Bharat. It also complements efforts to promote electric vehicles (EVs), reduce fossil fuel dependence, and accelerate the transition to green logistics solutions.

Challenges and Industry Response

While the initiative has been widely lauded by environmental groups, transport operators have raised concerns about the cost and availability of BS-VI compliant vehicles. Some industry bodies have requested financial support or incentives to aid the transition.

Conclusion

The CAQM’s strict enforcement roadmap marks a crucial step in addressing one of India’s most persistent urban challenges — air pollution. With the clock ticking towards the July 1 deadline, stakeholders across the logistics and transport sectors will need to respond swiftly to ensure compliance.

This regulatory shift not only strengthens India’s pollution control mechanisms but also sets the tone for a future-ready, eco-conscious transport ecosystem.
