Categorisation of Industries
- The Ministry of Environment, Forest and Climate Change categorises industries based on their pollution index score.
- Pollution index is the scale on a score of 0 to 100 for measuring the pollution potential of an industry.
- The Central Pollution Control Board (CPCB) classified certain industries into the orange category.
- The classifications are aimed at enhancing ease of doing responsible business.
- All organisations except those in white category need clearance from concerned regulatory authorities before commencing any construction or related activities (such as modernisation and expansion)
The categories specified by the Ministry based on the score are as follows:
- White: score up to 20,
- Green: score of 21 to 40,
- Orange: score of 41 to 59, and
- Red: score of 60 and above.
These industries being classified are:
- Building and construction projects with built-up area up to 20,000 square metres and waste water generation of 50 kilo litres or more per day,
- Construction and demolition waste processing plants, and
- Gold assaying and hallmarking centres. If the water waste generation of the concerned building and construction projects is 100 kilo litres or more per day, the projects will be classified into the red category.
