Consents and categorisation
- Consent to Establish (CTE) — before setting up an industry; Consent to Operate (CTO) — before starting production; renewed periodically.
- Categorisation of industries (2016) based on a pollution index (0–100): Red (index 60 and above — highly polluting), Orange (41–59), Green (21–40), White (up to 20 — practically non-polluting, no consent required). Red category industries are generally not permitted in ecologically fragile/protected areas.
