To regulate the pollution emitted by the vehicle, the government of India has made regulations known as Bharat Stage Emission Standards (BSES). The Central government has mandated that all vehicle manufacturers, both two-wheelers and four-wheelers, sell and register only BS6 (BSVI) vehicles from 1 April 2020.

What is meant by BS (BSES):
BSES – Bharat Stage emission standards (BSES) were introduced in the y2000.
- It is an emission standard instituted by the Government of India to regulate the output of Air pollutants from SI and CI engines.
- BS4 and BS6 emission norms are equivalent to Euro4 and Euro6 respectively.
- Currently BS4 emission norms are in place in India.
The government of India has decided to skip bs5 and implement bs6 emission norms by April 2020.
List of BS norms by year and region:
What is advantage of bs6 engines over bs4 engines?
- BS-6 emission norms are adopted from Euro 6 norms. Euro 6 norms are already adopted in European countries. Following are some of the benefits of BS6 Norms.
- Approximate 25% reduction in NOx emission in petrol engine and 68% reduction in diesel Engine.
- PM emission will reduce by approximately 80% in diesel engines.
- OBD2 will become mandatory for every vehicle. This will help in real time pollution monitoring.
- Real Driving Emission (RDE) in BS6 will measure the emission in real-world conditions and not just under test conditions.
Major reduction of pollutant in bs6 engine?
These are the major changes in bs6 over bs4.
- Major reduction in CO and HC in petrol vehicle whereas in diesel vehicle major reduction in NOx and HC and also in PM.
Some points about BS6 engine you should know:
A Green Sticker is specified for BS6 Vehicles (October 2020)
In an effort to differentiate BS6y vehicles from other vehicles, the Central Government has announced that all BS6 vehicles will bear a 1 cm green sticker. This will come into effect from 1 October 2020 and it will include the registration details. This green sticker will be placed at the top of the registration sticker, Also include colour coding for the type of fuel being used by the vehicle.
Vehicle Scrappage Policy in India:
The Union Transport Minister said that the government is all set to start the vehicle scrappage policy. Recycling clusters will be built near ports. He also said that through this initiative India, in five years, will emerge as the world’s leading automobile manufacturing hub. Under the policy, old cars, buses and trucks will be scrapped.
BS4 Vehicles Banned From From 1 April 2020:
The road transport ministry has directed all states and Union Territories (UT) in the country to stop selling BS IV vehicles in India from 1 April 2020. On the behalf of lockdown, the Ministry in its directive has also attached the Supreme court order to sell 10% BS4 vehicles of the total unsold stock, but this does not apply to Delhi and NCR region.
