# Government proposes three-phase BS7 emission norms from April 2029 2026-10-15T07:01:27+00:00 | Governance | Indian Opinion Desk Corroboration: 2 independent outlets The road transport and highways ministry (MoRTH) has proposed Bharat Stage 7 (BS7) emission norms, set for a phased rollout starting 1 April 2029. The draft gazette notification, released on 12 October, plans the first phase for cars and SUVs from April 2029, followed by small commercial vehicles in April 2030, and trucks and buses from April 2031, with some provisions extending to April 2035. The new standards will monitor particles as small as 10 nanometres, covering not just exhaust emissions but also tyre and brake wear. The proposal targets a 20 to 50% reduction in emission limits for heavy vehicles. Existing BS6 vehicles will not be banned or required to be scrapped. The final implementation timeline depends on the government's official notification. ## Indian Opinion Analysis Both Aaj Tak and Business Today report the proposed BS7 norms as a government plan with neutral, explanatory framing. Aaj Tak leads with the phased timeline from April 2029 to April 2035 and details the particulate matter testing threshold of 10 nanometres, while Business Today focuses on contrasting BS7 with the existing CAFE 3 standards, which target fuel economy and run from April 2027. Neither outlet criticises or promotes the policy, both present it as a straightforward regulatory proposal. The single difference is emphasis: Aaj Tak is more technically detailed on testing methods, Business Today is more comparative. The coverage is uniform straight reporting of the government draft. The final notification from the transport ministry will confirm whether the proposed April 2029 start date holds. ## Coverage Coverage: 2 sources, 2 neutral - aajtak.in (neutral report) Explanatory, detailed timeline and technology focus - businesstoday.in (neutral report) Comparative explainer, contrasts BS7 with CAFE 3 This brief was synthesised by AI from the 2 sources linked above, so one read covers every framing they carry.
