The National Green Tribunal has ordered the Uttar Pradesh Pollution Control Board to submit a detailed report on establishments operating without environmental clearance in Ghaziabad district. The tribunal warned that the UPPCB could be liable for environmental compensation and the officers responsible could be prosecuted for abetting pollution. The UPPCB had previously issued show-cause notices to 20 establishments for operating without consent. However, the NGT found the report submitted by the UPPCB to be unsatisfactory.
