The Ministry of Road Transport and Highways (MoRTH) has proposed extending the Pollution Under Control Certificate (PUCC) validity for BS-VI private vehicles up to six years old from one year to three years. The draft rules also introduce stricter testing intervals for older and higher-emission vehicles to improve air quality.
Key Highlights
- BS-VI private vehicles up to six years old may get 3-year PUCC validity.
- BS-VI commercial vehicles up to six years old to receive 2-year PUCC validity.
- BS-IV vehicles will require PUCC renewal every six months.
- BS-I, BS-II and BS-III vehicles must renew PUCC every three months under the proposed rules.
New Delhi, July 28: The Ministry of Road Transport and Highways (MoRTH) has issued a draft notification proposing significant changes to the Pollution Under Control Certificate (PUCC) renewal system, aimed at reducing compliance requirements for cleaner vehicles while strengthening emission monitoring for older vehicles. Under the proposal, BS-VI private vehicles that are up to six years old will receive a three-year PUCC validity, replacing the current one-year validity. Similarly, BS-VI commercial vehicles of the same age category will be eligible for a two-year PUCC validity, recognising their lower emission levels and improved environmental performance.
The draft notification introduces a graded renewal framework based on the age and emission standard of the vehicle. BS-VI vehicles between six and ten years old will be required to renew their PUCC annually, while vehicles older than ten years must undergo emission testing every six months. This approach seeks to balance regulatory compliance with environmental protection by ensuring that older vehicles remain within prescribed emission limits throughout their operational life.
The proposed rules also tighten compliance requirements for vehicles operating under older Bharat Stage (BS) emission norms. BS-IV vehicles will now require PUCC renewal every six months, compared with the existing annual requirement. Even stricter provisions have been proposed for BS-I, BS-II and BS-III vehicles, which will need to renew their Pollution Under Control Certificates every three months due to their comparatively higher tailpipe emissions. The ministry believes more frequent inspections will help reduce emissions of pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM), contributing to cleaner urban air.
Bharat Stage (BS) emission standards define permissible limits for vehicular pollutants and are aligned with European emission regulations. While BS-IV norms were implemented between 2017 and 2020, India transitioned directly to the more stringent BS-VI standards from April 1, 2020, skipping BS-V to accelerate pollution control. BS-VI fuels contain a maximum sulphur content of 10 parts per million (ppm), compared with 50 ppm under BS-IV, enabling cleaner combustion, lower emissions and improved vehicle performance. The proposed PUCC reforms are expected to support India’s broader efforts to improve air quality while easing compliance for owners of newer, environmentally friendly vehicles.
The proposed PUCC validity reforms reflect the government’s strategy of encouraging cleaner vehicle technologies while imposing stricter monitoring on older, higher-emission vehicles. If notified, the new rules will simplify compliance for BS-VI vehicle owners and strengthen India’s vehicle emission control framework.
