News: The National Green Tribunal (NGT) has directed pollution control boards of all States to obtain information from all local bodies pertaining to pollution caused by dairy farms and submit relevant data to the Central Pollution Control Board (CPCB).


The directions came when the green panel was hearing a set of pleas seeking remedial action for compliance of environmental norms by the dairies.

Directions given by NGT

  • The State pollution control boards and pollution control committees were directed to furnish factual and action-taken reports to the apex pollution control body by April 2020.

  • Private operators, including cooperative societies or other entities, not falling within the jurisdiction of local bodies, may also furnish the requisite information to the State PCBs within one month.

Way ahead

The State PCBs/ PCCs (pollution control committees) may publish an appropriate notice on the subject within two weeks requiring furnishing of information and also adopting all necessary safeguards in the matter.

Various categories of industries

  • The Ministry of Environment, Forest and Climate Change (MoEFCC) has developed the criteria of categorization of industrial sectors based on the Pollution Index which is a function of the emissions (air pollutants), effluents (water pollutants), hazardous wastes generated and consumption of resources.

  • The Pollution Index PI of any industrial sector is a number from 0 to 100 and the increasing value of PI denotes the increasing degree of pollution load from the industrial sector.
