News:Minister for the Environment has said that the country will shift to Bharat Stage Six (BS-VI) vehicular emission norms from BS-IV by April 2020.
Facts:
About Bharat Stage norms:
- Bharat Stage(BS) are emission standards instituted by the Government of India based on European regulations.
- The objective is to regulate the output of air pollutants from internal combustion engine equipment.The higher the fuel standard a vehicle complies with,the less polluting it is.
- The standards and the timeline for implementation are set by the Central Pollution Control Board under the Ministry of Environment & Forests and Climate Change.
Implementation:
- In order to curb the growing menace of air pollution through the vehicles emission,the Government of India has decided to move from the existing BS – IV norms directly to the BS- VI with effect from 1st April 2020.
- The main difference between BS-IV and BS-VI (Which is comparable to Euro 6) is in the amount of sulphur in the fuel.
- BS-VI fuel is estimated to bring around an 80% reduction in sulphur content –from 50 parts per million (ppm) to 10 ppm.
- The Nitrogen Oxide(NOx) emissions from diesel cars are also expected to come down by nearly 70% and from cars with petrol engines by 25% after the implementation of BS-VI fuel.
