Delhi has earned the tag of the world's most polluted city following the presence of high level of particulate matter in its air.
Car makers Toyota, Mahindra and Mercedes have moved Supreme Court asking that their cars be made exempt from the ban on diesel car registration it had imposed.
The companies have argued that their diesel vehicles are used in villages and for public service, and stopping their registration will greatly inconvenience people.
The court will hear the case tomorrow.
On December 16, in a bid to cut down on vehicular emissions in Delhi and NCR, the top court had baned the registration of diesel vehicles over 2000 cc.
Reacting to the ban, Mahindra had issued a statement saying, "The Company respects the order of the Honourable Supreme Court and does hope that these actions help to clean Delhi air."
Toyota Kirloskar Motor chairman Vikram Kirloskar had said the company will study the order. Toyota's bestselling Fortuner and Innova account for big sales in Delhi, which has earned the tag of the world's most polluted city following the presence of high level of particulate matter in its air.
To tackle the emission issue, the top court had issued a number of orders, including a ban on entry of trucks, commercial vehicles registered before 2005, and said taxis in NCR convert to CNG by March this year.
The Delhi government is implementing a pilot odd-even programme that is expected to cut down the number of private vehicles to half on city roads.
