- BS – 6 or Bharat stage 6.
- BS – 6 is the new emission standard that all vehicles in the country will have to
adhere to from April 1, 2020. The sale of BS-4 vehicles will also cease from this day.
- The supreme court had ruled on October 24, 2019 that no BS-4 vehicle could would
be sold with effect from April 1, 2020.
- Bharat stage emission standards are emission regulations implemented by the
government to keep a check on emissions from motor vehicles.
- Finance minister Nirmala Sitaraman has already clarified that BS-4 vehicles
purchase upto March 2020 will remain operational for the entire duration of the
- Introduced first in 2000, the current BS-4 norms were enforced in the year 2017,
after BS-2 and BS-3 norms which were enforced in 2005 and 2010 respectively. BS-
5 have been skipped in order to have a more standard to curb pollution level.
- Basically, for companies who are making petroleum products like petrol and diesel
vehicles. The content of Sulphur Nitrogen will go down so that the exhaust, the
elements are prescribed that the Sulphur Dioxide, Nitrate Oxide, Carbon Monoxide
as such poisonous gases their limits must go down considerably.
- From BS-4 to BS-6, skipping BS- 5, so in short period of time both the refineries
which make petroleum products and for auto – manufacturer who make auto,
quality of fuel itself will not serve the purpose.
- The car or vehicle should also have facility to take that fuel and the exhaust should
come out at much lower level so that there is full combustion and the particular
matter is reduced, the exhaust does not contain higher component of Carbon
Monoxide, Sulphur Dioxide, Nitrate Oxide and some other gases.
- Both the Refineries have to work better quality fuel the automobile company have
to work for new technology in combustion. If, both are ready we can have cleaner
atmosphere because the transport sector does contribute to air pollution in a
Difference between BS-6 and BS-4
1. Sulphur content must be minimal.
2. In case of BS-4 and BS-3 on the implementation day, North-East and Kerala were
3. But this time, we are implementing the entire process single day across the
country, there is no faced implementation.
- Vehicles that move across the country are trucks, there are 85% of the
commercial vehicles population now, the truck operates are neither buying BS-4
vehicles no they will be in a position to buy immediately BS-6 vehicles because
BS-6 vehicles when introduced on April 1, very few people have data available to
- A change – whenever we have introduction of BS-2, BS-3 and BS-4 used to have
it in phase manner.
- Not only sale and production, even registration will stop on 31st March.
- Preparedness, industries are well prepared, lots of two wheeler companies and
other companies have already rolled on BS-6 vehicles 5-6 months before.
- Right from BS-1 to BS-2 to BS-3 to BS4, the adoption was done in phase manner.
First, the NCR town, major town, towns in other states and their after in in
- Auto manufacturers – most of them are International German companies, US
companies, Japanese companies and Korean companies and they are supplying
automobiles which are suitable for BS 6.
- BS-6 fuels and vehicles irrespective of usage must come to the country because
the country cannot afford this polluted atmosphere. The government has to
ensure that if they are going to add BS 6 vehicles, there could be reason they
could have taxation, concession and customers to be encourage.
- The people who have invested in BS-6 vehicles, diesel and petrol vehicles, they
have to face competition from CNG, LNG and Hydrocell vehicles as well as
- Effective GST today is about 38-40% for smaller vehicles, some roll back of GST
is required as we see the cost analysis.
- When transmitted from BS1 to 2 to 3 to 4 there was also always improved fuel
efficiency so that vary selling point for industries dealers and government. The
way structure is happening from BS-4 to BS-6 it improves, it reduces the
emission phenomena but fuel efficiency will remain same or say small reduction.
- 20% of the pollution in air is due to transport sector, in due course maybe in 5 to
6 years our cities will become clearer.
