Countrywide ban on the sales of non BS-IV vehicles to be implemented

As an act to counter the goliath threat of vehicle pollution in the country, Indian government has finally decided to mandate the BS-IV emission norms throughout the country. At present these norms are put into effect only in the metros such as New Delhi, Mumbai, Kolkata, Chennai and Hydrabad. In the rest of the country, selling of BS-III complaint vehicles is still allowed legally.


Government plans to extend the compulsion of BS-IV norms to the rest of the country, implementation of which would be carried out in different phases. The next ones on the ladder are Jammu & Kashmir, Punjab, Haryana, Uttarakhand, Himachal Pradesh and UP where BS-IV norms will be forced from this October. Later, in April 2016, Kerala, Karnataka, Odisha, Telangana, Pune & Thane in Maharashtra and Surat in Gujarat would be covered under this scheme.

Implementation of BS-IV norms throughout the country is certainly a welcoming step from the environment point of view but immediate steps are also necessary to migrate towards the higher standards like BS V & BS VI because these norms need high standards of infrastructural capabilities like higher grade fuel and more efficient engine technology.
