"We keep talking, sometimes make statements and suggestions, but the point is that AQI is already touching 400," the CJI said.
The bench also flagged the large number of vehicles on roads connecting Delhi to neighbouring areas, including Ghaziabad, Greater Noida, Gurugram and Faridabad.
"Look at the roads in Delhi and the roads connecting Delhi with the NCR. Take a look at any road and the kind of vehicles moving on them. That is the major problem," the CJI said.
