"I am being told that over 50 per cent of pollution in Delhi is caused by fine particulate matter which originates from neighbouring states. The air quality in Delhi is getting worse. You should take every measure to introduce CNG stations in your states. If you don't introduce CNG in you state, we will stop your state transport," a bench headed by NGT Chairperson Justice Swatanter Kumar said.
The Tribunal directed senior officials from states of Haryana, Punjab, Rajasthan and Uttar Pradesh, besides officers of Petroleum and Natural Gas Regulatory Board, to appear before it on October 19, the next date of hearing.
The NGT in September had asked Uttar Pradesh and Haryana government to mull over the possibility of installing CNG stations in NCR while refusing to grant permission to over 10- year old diesel vehicles to ply in these areas.
On July 18, the green panel had directed authorities in Delhi-NCR to cancel the registration of all diesel-powered vehicles which are more than 10 years old.
