Supreme Court Extends Deadline of Transition from BS IV to BS VI

With the Nation-wide Lock Down to contain the spread of Corona Virus, the Supreme Court extended transition from BS IV to BS VI by 10 more days. Initially the deadline was March 31, 2020. However, the order does not apply to the National Capital Region.


The order comes after the Federation of Automobile Dealers Association moved to the Supreme court to relax the deadline to sell their stocks of BS IV vehicles. According to the petition filed by the association, currently there are 7 lakhs unsold two wheelers, 12,000 commercial vehicles and 15,000 cars of BS IV standard.

BS VI Standard

The BS VI standard emits five times lesser than that of BS IV standard. The major upgrade that is being brought in BS VI standard is in terms of fuel. A BS VI vehicle should use BS VI fuel. The BS VI fuel has five times lesser Sulphur. Also, the nitrogen oxide levels for BS VI petrol and diesel engines are to be brought down by 70% and 25%.

The Bharat Stage Emission norms were brought in 2000 based on European Emission standards. The standards are set by the Central Pollution Control Board.

Rajasthan that was ranked 16th in 2018 was awarded the best water management status.
