In India, industries and projects that impact the environment must obtain two primary clearances from their respective State Pollution Control Board (SPCB): Consent to Establish (CTE) and Consent to Operate (CTO). These are mandatory under the Water Act, 1974 and the Air Act, 1981 Industry Categorisation SPCBs classify industries into four color-coded categories based on their Pollution Index (PI): • Red Category: High pollution potential (e.g., thermal power plants, large chemical units). • Orange Category: Moderate pollution potential (e.g., food processing, pharmaceuticals). • Green Category: Low pollution potential (e.g., small-scale manufacturing). Some states allow auto-renewal for this category. • White Category: Practically non-polluting; usually exempt from consent but may require simple registration
