• Industrial Sectors having Pollution Index score of 60 and above – Red category
  • Industrial Sectors having Pollution Index score of 41 to 59 – Orange category
  • Industrial Sectors having Pollution Index score of 21 to 40 – Green category
  • Industrial Sectors having Pollution Index score incl.& upto 20 – White category

The newly introduced White category of industries pertains to those industrial sectors which are practically non-polluting such as Biscuit trays etc. from rolled PVC sheet (using automatic vacuum forming machines), Cotton and woolen hosiers making (Dry process only without any dying/washing operation), Electric lamp (bulb) and CFL manufacturing by assembling only, Scientific and mathematical instrument manufacturing, Solar power generation through photovoltaic cell, wind power and mini hydel power (less than 25 MW).

The salient features of the “Re-categorization” Exercise are as follows :

  • Due importance has been given to relative pollution potential of the industrial sectors based on scientific criteria . Further, wherever possible, splitting of the industrial sectors is also considered based on the use of raw materials, manufacturing process adopted and inturn pollutants expected to be generated.
  • The Red category of industrial sectors would be 60.
  • The Orange category of industrial sectors would be 83.
  • The Green category of industrial sectors would be 63.
  • Newly introduced White category contains 36 industrial sectors which are practically nonpolluting.
  • There shall be no necessity of obtaining the Consent to Operate for White category of industries. An intimation to concerned SPCB / PCC shall suffice.
  • No Red category of industries shall normally be permitted in the ecologically fragile area / protected area.

The purpose of categorization is to ensure that the industry is established in a manner which is consistent with the environmental objectives. The new criteria will prompt industrial sectors willing to adopt cleaner technologies, ultimately resulting in generation of fewer pollutants. Another feature of the new categorization system lies in facilitating self-assessment by industries as the subjectivity of earlier assessment has been eliminated. This “Re-categorization” is a part of the efforts, policies and objective of present government to create a clean & transparent working environment in the country and promote the Ease of Doing Business.
