The Central Pollution Control Board (CPCB) introduced the "Blue Category" as part of its revised industrial classification based on the Pollution Index. This newly classified colour is specifically designated for essential environmental services such as waste-to-energy plants and compressed biogas facilities. These services, while crucial for sustainability, generate relatively low pollution compared to heavier industries. The Blue Category complements the existing colour-based classification system of Red, Orange, Green, and White by providing a distinct slot for low-pollution but essential infrastructure. It also offers a two-year extension for consent validity, encouraging the growth of environmentally responsible sectors.
