New Delhi has become the first city in India to deploy Bharat Stage 6 Fuel for both petrol and diesel. two years ahead of the rest of the county.
- The idea behind this implementation two years ahead of the previously scheduled date of April 1, 2020, is to help battle Delhi’s long-standing terminal pollution problem.
- The BS — or Bharat Stage — emission standards are norms instituted by the government to regulate the output of air pollutants from internal combustion engine equipment, including motor vehicles. India has been following the European (Euro) emission norms, though with a time-lag of five years.
Difference between BS-IV and the new BS-VI:
- The major difference in standards between the existing BS-IV and the new BS-VI auto fuel norms is the presence of sulphur. The newly introduced fuel is estimated to reduce the amount of sulphur released by 80 per cent, from 50 parts per million to 10 ppm. As per the analysts, the emission of NOx (nitrogen oxides) from diesel cars is also expected to reduce by nearly 70 per cent and 25 per cent from cars with petrol engines.
