March 12, 2025: Delhi, which continues to be the most polluted capital in the world, has ordered a ban on old vehicles to combat air pollution. Starting March 31, vehicles older than 15 years will no longer be allowed to refuel at petrol pumps. This move aims to curb vehicular emissions and reduce pollution in the city.

Additionally, the Delhi Transport Department has directed that No Objection Certificates (NOCs) be issued for de-registered diesel vehicles between 10-15 years old, allowing them to be transferred to other states. However, no NOC will be issued for diesel vehicles older than 15 years, and such vehicles will be scrapped.

The Delhi government has also started scrapping old petrol and diesel vehicles and procuring electric ones to fight air pollution. Moreover, all high-rise buildings, hotels and commercial complexes in Delhi are ordered to install anti-smog guns to reduce pollution.
