India’s Next Emission Shift: BS-VII Rules for New Cars, SUVs Planned From April 2029

India is preparing for another major shift in vehicle pollution control, with the government proposing to introduce BS-VII emission standards for new cars and SUVs from April 1, 2029. The stricter rules are expected to tighten limits on harmful emissions, putting pressure on automakers to develop cleaner vehicles while raising questions about the cost of future models.

The Ministry of Road Transport and Highways (MoRTH) has proposed a three-phase rollout spanning six years, from April 2029 to April 2035, according to a draft gazette notification dated October 12.

Under the proposed schedule, the first phase would begin on April 1, 2029, followed by the second phase in April 2031 and the final phase in April 2035. The phased approach would give the automotive industry time to adapt its vehicle technologies and manufacturing processes to increasingly stringent pollution-control requirements.

The proposed standards seek to impose tighter limits on pollutants, including nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM), which contribute to poor air quality and pose risks to public health. The final requirements will depend on the notification being finalised after the draft process.

For motorists who already own vehicles, the proposal offers an important distinction: existing vehicles, including those complying with BS-VI standards, will not be affected by the new norms or have their permitted life curtailed under this proposal. The planned changes are aimed at new vehicles covered by the rules.

Bharat Stage emission standards regulate the amount of pollutants vehicles can release. They are aligned with European emission regulations and have been tightened over time to reduce the environmental impact of road transport.

India implemented BS-VI standards in April 2020, skipping BS-V altogether to accelerate pollution-control measures. The transition also required the use of low-sulphur BS-VI-compliant fuel and prompted manufacturers to upgrade engine and exhaust-treatment technologies.

The proposed move to BS-VII would mark another step in that transition. However, its impact will extend beyond regulatory compliance: automakers may need to invest in cleaner engine systems, testing and production upgrades, while the eventual effect on vehicle prices will depend on the final standards and the cost of meeting them.
