The Kerala State Pollution Control Board (KSPCB) on March 7th2025 has issued a notification regarding the revised category list of industries under the Red, Orange, Green, and White categories. The revised categorization has been implemented as per the direction of the Central Pollution Control Board (CPCB).
Key Updates:
The industries listed below have been categorized based on their potential to cause pollution. These categories were finalized following discussions in the Categorization Committee meetings held on February 11, 2025, and February 18, 2025. The committee relied on the CPCB’s Classification of Sectors into Red, Orange, Green, White, and Blue categories (January 2025) for the classification.

As of now, 310 industries that were not included in the earlier circular have been added to the updated list. The categorization ensures effective management of industries based on their environmental impact and potential for pollution.
This circular serves to ensure that industries are categorized appropriately, allowing for better regulation and environmental management in the state.
