Worried about the deteriorating air quality in the national capital Delhi, the National Green Tribunal (NGT) on Friday threatened to suspend entry of Haryana, Punjab, Rajasthan and Uttar Pradesh transport vehicles if they did not switch to CNG.
“What have you done with regard to introduction of CNG stations in your areas? What are you doing about this? We had asked you to submit your response on the issue. What have you done on this?
“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 observations came during the hearing of a case filed by Vardhaman Kaushik on the deteriorating air quality in Delhi, a news agency has reported.
According to a report jointly prepared by TERI and the University of San Diego, California, about 60-80% of ozone concentration in Delhi is attributed to sources outside the city.
