India’s Industrial Green Belt Requirements Revised for Sustainable Growth. ESG Broadcast Shares Key Takeaways.
Key Extract
The Ministry of Environment, Forest and Climate Change (MoEFCC) officially revised green belt standards for industrial areas. This major decision was formally announced in an Office Memorandum (OM) issued on October 29, 2025, by the Impact Assessment Division. The new policy effectively set revised green cover requirements for industrial estates, parks, and individual industries. The notification clearly detailed the new mandated area based strictly upon the respective pollution potential of each industrial unit.
The necessity for a green belt was initially established under the EIA Notification of 2006 which mandated prior Environmental Clearance. Earlier guidelines had standardized the EC conditions, generally stipulating a 33% green belt for most developmental sectors. A subsequent 2019 OM introduced a stricter 40% criterion for high pollution industries located in designated Critically Polluted Areas. This specific, stringent measure was implemented for compliance with a significant National Green Tribunal (NGT) order.
The following norms will supersede the OM Dated October 27, 2020 and must be followed while developing green belts/ Green cover areas. At least 10% of the total area of an industrial estate should be designated as a common green area with dense plantation, comprising approximately 2,500 trees per hectare. This green area should be developed by the owner of the industrial estate and may either be established at a single location or distributed across multiple designated areas within the premises, provided it is clearly demarcated and collectively accounts for 10% of the total estate area. Furthermore, individual industries operating within the industrial estate must also allocate a minimum area for green belt development within their premises, depending on their category: red category industries are required to maintain a minimum of 15% green belt, orange category industries 10%, while for green and white category industries, green belt development is optional with no mandatory requirement.
Individual industrial units outside industrial estates requiring Environmental Clearance (EC) must follow green belt norms as recommended by the sectoral or State-level Expert Appraisal Committees (EAC/SEAC) specified in the EC conditions. For predominantly air-polluting sectors, red category industries must allocate 25% of their area as green belt (PIₐ ≥ 80), orange category 20% (PIₐ ≥ 55), and green category 10% (PIₐ ≥ 25), while white category industries have no mandatory requirement. For other sectors, red and orange categories must maintain 20% and 15% green cover respectively, whereas green and white categories are optional with no compulsory green belt requirement.
New specifications detailed the proper development and subsequent maintenance of the crucial industrial green cover. The industrial green belt must be established along the periphery of the project area, forming a minimum width of 10-20 meters. Authorities mandated that only native species should be selected and planted densely to ensure good canopy coverage. This complete green belt area must be strategically utilized and maintained strictly within the respective industrial estate’s boundary. Proper upkeep was deemed absolutely necessary to guarantee effective carbon sequestration and sustained environmental quality.
Strategic significance lies in the comprehensive monitoring mechanism introduced to ensure strict compliance across all sectors. Industrial Estates are required to submit a half-yearly status report to both the SPCB/PCC and the IRO of MoEFCC. These reports included crucial details about canopy coverage, species, survival rates, and mandatory drone imagery. Individual industrial units must also submit half-yearly reports detailing total area, tree number, and species types to their SPCB/PCC. Furthermore, details of individual units are subject to random verification by the SPCB/PCC during routine site inspections.
