  • Automotive manufacturers have to comply to sell their vehicles in India
  • Applicable to all two wheelers, three wheelers, fourwheelers and construction equipment vehicles.
  • Government of India has decided to leapfrog from the exiting BS – IV norms to the BS- VI, thereby skipping the BS – V norms, and to implement the BS – VI norms with effect from 1st April 2020.
  • Stringent and at par with global standards.

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%, 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% and 25% from cars with petrol engines.
