The Punjab Pollution Control Board (PPCB), on November 24, 2025, issued an order referencing earlier communications regarding the adoption of CPCB’s updated framework for harmonized classification of industrial sectors. These CPCB directions dated February 12, 2025, March 25, 2025, and corrigendum dated November 11, 2025, superseded all earlier categorizations and mandated uniform classification into Red, Orange, Green, White, and Blue categories.
To classify left-out industrial sectors not covered in the CPCB schedule, the Board had constituted a Committee under the Chairmanship of its Member Secretary via Office Memorandum dated March 19, 2025. Based on the Committee’s recommendations, PPCB has now approved the inclusion of six additional sectors under the Orange category, eleven sectors under the Green category, and the introduction of a “Miscellaneous” category within the Red and Orange categories for better regulatory clarity.
The updated sectoral lists have been circulated for information and necessary implementation by all concerned authorities.
