India proposes BS-VII vehicle emission rules starting April 2029

India proposed Bharat Stage VII (BS-VII) vehicle emission standards to address pollution from brakes and tyres, battery durability, and testing under realistic driving conditions.

The Ministry of Road Transport and Highways proposes a phased rollout starting with passenger cars from April 1, 2029, light commercial vehicles in 2030, and heavy trucks in 2031.

For cars, the draft retains principal tailpipe limits for carbon monoxide, nitrogen oxides, and particulate matter, while lowering the particle-number measurement threshold from 23 to 10 nanometres.
