New Delhi: The Supreme Court on Monday observed that the ban on registration of diesel vehicles over the capacity of 2000cc will continue until further notice.

The top court, however, said that it was willing to go easy on the order banning diesel-run all-India tourist permit taxis which ferry BPO employees in Delhi-NCR region.

On December 16 last year, senior advocate Harish Salve recommended all diesel-run taxis be banned from the roads of Delhi NCR unless they convert to CNG. The SC had considered the recommendation and given a deadline of March 1, 2016.

The Delhi government, along with the Centre and Environment Pollution Control Authority (EPCA) then came together and announced that the taxi permits for all diesel taxis will be renews only under one condition – if they switch to a greener CNG option. This had caused massive traffic jams across the city bringing the city almost to a standstill.

The Supreme Court had earlier, on April 30, refused to extend the deadline given to diesel taxis to switch to CNG, and banned the cabs from plying on the Delhi-NCR roads from May 1.

There are around 55,000 diesel-run taxis with all-India permit.
