New Classification of Industries Based on Pollution Index
Context
Recently, the Central Pollution Control Board (CPCB) has revised its classification of industrial sectors based on their Pollution Index (PI), aiming to ensure more effective pollution control and regulatory oversight.
Relevance:
GS-03 (Conservation)
Key Highlights
Revised Categorization
- A total of 419 industrial sectors have been classified into five pollution-based categories:
- Red: 125 sectors (Highest pollution potential)
- Orange: 137 sectors
- Green: 94 sectors
- White: 54 sectors (Minimal pollution, no need for consent)
- Blue: 9 sectors (Newly introduced category)
Methodology Update
- Based on Pollution Index (PI) introduced in 2016
- Equal weight is given to pollution caused by: Air emissions, Water effluents and Hazardous waste generation
The New Addition—Blue Category:
- Focused on Essential Environmental Services, which help manage pollution from domestic and industrial sources
- Includes waste treatment services and other utilities.
Compressed Biogas (CBG) Plant Classification:
- CBG plants using domestic feedstock (e.g. municipal solid waste, agro-residue, weeds) now fall under Blue Category
- CBG plants using industrial waste will continue to be classified under the Red Category
Incentives for Industries: Sectors with good environmental compliance will benefit from faster and extended permit approvals
Significance:
- Encourages environment-friendly industrial practices
- Promotes sustainable development by clearly defining sectoral pollution levels
- Supports bioenergy and waste management industries
(Prelims Practice Question)
- With reference to the new classification of industries by the Central Pollution Control Board (CPCB), consider the following statements:
- The Blue category includes industries that offer essential environmental services such as waste management.
- Compressed biogas (CBG) plants using agro-residue and municipal waste are now classified under the green category.
- The Pollution Index (PI) considers air, water, and hazardous waste pollution equally while classifying industries.
Which of the statements given above is/are correct?
- 1 and 3 only
- 2 and 3 only
- 1 and 2 only
- 1, 2 and 3
Answer: A. 1 and 3 only
