A categorization of industries based on their pollution load has been released by the Ministry of Environment, Forest and Climate Change (MoEFCC).

The purpose of the 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 the government to create a clean & transparent working environment in the country and promote the Ease of Doing Business.

Categories and criteria for categorisation

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.

For this purpose the references are taken from the the Water (Prevention and Control of Pollution ) Cess (Amendment) Act, 2003, Standards so far prescribed for various pollutants under Environment (Protection) Act, 1986 and Doon Valley Notification, 1989 issued by MoEFCC. 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. The following are the criteria on ‘Range of Pollution Index' for the purpose of categorization of industrial sectors.

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

Implications of categorisation

Non-polluting white category industries will not be required to take Consent to Establish (CTE) or Consent to Operate (CTO) at all. The industries who have taken EC will not be required to take CTE. The CTE fee shall be required to be paid by the industry, so that there is no loss of revenue to the States.
No Red category of industries shall normally be permitted in the ecologically fragile area / protected area.
