NEW DELHI: Having enforced Bharat Stage (BS) IV fuel emission norms in the major metropolitan cities from April 1, the Centre has decided to enforce BS III norms across the rest of the country from October 1.
The BS III will be with respect to two-, three- and four-wheelers. The Centre could not enforce the norm from April 1 as the refinery companies were not prepared.
BS IV norms will come into force in Lucknow and Sholapur from May 20.
While the notifications to enforce the two decisions are set to be issued soon, the Ministry of Road Transport and Highways will also be issuing a post-fact notification in respect of enforcement of BS III norms for two- and three-wheelers in the National Capital Region and other mega cities.
