Delhi Chief Minister Arvind Kejriwal on Thursday launched a campaign to tackle air pollution in the national capital and urged people to switch off the engines of their vehicles while waiting at traffic signals.
Addressing an online media briefing, the chief minister said that there are one crore vehicles registered in the city.
If 30-40 lakh vehicles come on the road everyday and keep idling at traffic signals, it increases air pollution levels in the city, Kejriwal said.
