The government is set to roll out BS-VII emission norms, aligned with Euro 7 standards, in a phased manner starting April 2029 to curb harmful pollutants amidst heightened pollution risks across Indian cities.
The updated standards will establish stricter limits on emissions such as nitrogen oxides, hydrocarbons, and particulate matter. The road transport ministry has approved the proposed timeline, with draft notifications for vehicle categories expected over the coming days, according to officials familiar with the matter.
Unlike the transition to BS-VI in April 2020, officials stated that the implementation of the new standards will not require changes in refinery infrastructure for producing suitable petrol and diesel. However, the automobile sector will be required to upgrade engine technologies to comply with the rules.
Key Points Of The BS-VII Emission Norms
- Rollout spans six years across three phases from April 2029 to April 2035.
- New cars and SUVs manufactured from April 2029 are covered in the first phase.
- Small goods delivery and pick-up vans follow in 2030, with buses and heavy-duty vehicles scheduled for April 2031.
- Regulations for two-wheelers will be notified at a later date.
- Existing vehicles and their operational life, including BS-VI compliant models, will remain unaffected.
Phased Implementation Timeline And Vehicle Categories
The implementation will be structured across three phases spanning six years, running from April 2029 to April 2035 to give the automotive industry and testing agencies adequate time for adaptation. New cars and SUVs manufactured from April 2029 will lead the rollout.
Small goods delivery and pick-up vans will follow in the second phase starting in 2030. Buses and heavy-duty commercial vehicles are scheduled to comply with the standards beginning April 2031.
The regulatory framework broadens monitoring from controlled laboratory tests to ensure vehicles meet prescribed limits under real-world driving conditions throughout their operational life. Furthermore, independent testing agencies will conduct in-use compliance checks under a newly introduced market surveillance concept.
Stringent Emission Limits And Non-Exhaust Sources
Under the finalized norms for cars and SUVs, cut-off limits for standard emission components remain unchanged compared to BS-VI. However, the particulate number threshold has been reduced from 23 nanometres to 10 nanometres to improve filtration of ultrafine particles that penetrate deeper into lungs and were previously unregulated.
The transition will have a greater impact on trucks and heavy-duty vehicles, with standards aiming for a 20% to 50% reduction in emissions across various pollutants. Officials noted that BS-VII goes beyond tailpipe emissions by regulating non-exhaust sources such as brake wear and tyre abrasion.
The rollout structure aligns fully with Euro 7 implementation schedules, which began in November 2026 for light-duty vehicles and May 2028 for heavy-duty vehicles, extending to 2035 for full implementation.
Frequently Asked Questions
When will the BS-VII emission norms start?
The BS-VII emission norms are scheduled to begin in a phased rollout starting with new cars and SUVs manufactured from April 2029, with full implementation extending up to April 2035.
Do BS-VII emission standards affect existing vehicles?
The proposed BS-VII emission standards will not affect existing vehicles or their operational life, including those currently compliant with BS-VI standards.
