The Haryana government on Thursday banned 15-year-old petrol and 10-year-old diesel vehicles from roads within NCR limits.
This will apply to vehicles registered in cities falling under the territorial jurisdiction of National Capital Region such as Gurgaon, Faridabad, Sonipat and Jhajjar which cause significant air pollution.
According to the latest World Health Organisation reports, Delhi occupies the 11th position on the list of most polluted cities in the world.
The situation is particularly bad in NCR where recent pollution levels have been reported to be much higher than the acceptable limits on most days of the year, sometimes as high as 35 times the normal level.
