The green panel constituted the committee comprising officials from the Ministry of Environment and Forests (MoEF), Central Pollution Control Board (CPCB), Delhi Pollution Control Committee (DPCC) and Shriram Laboratory to collect samples for a duration of one week.
"CPCB, DPCC, Shriram Laboratory, Ministry of Environment and Forests to prepare a complete and comprehensive report on ambient air quality in at least 10 different sites in NCT Delhi for a period of one week. The samples shall be collected during peak and non-peak hours," a bench headed by NGT Chairperson Justice Swatanter Kumar said.
Noting that the Supreme Court was already hearing a case related to air pollution in the capital, the green panel said it would restrict its orders to "places other than Delhi".
On December 18, the tribunal had refused to vacate its order banning registration of new diesel-run vehicles, saying it would not interfere with the apec court order which has taken a similar stand.
The apex court has now extended the bar on registration of diesel-run SUVs and high-end cars in the National Capital Region till April 30.
