Calculate your green belt

Choose the line that matches your clearance. If your clearance states a share, enter it; it overrides the default.

This is a planning estimate, not legal advice. The conditions in your environmental clearance and consent to operate prevail.

Quick answer

How much green belt does an industrial unit need in India?

It depends on your environmental clearance. Older clearances often set 33% of the project area. For new and pending applications, a ministry memorandum of 29 October 2025 sets minimums by category: 15% (red) or 10% (orange) for units in industrial estates, 20 to 25% (red) or 15 to 20% (orange) for standalone units, and 40% for red and orange units in critically or severely polluted areas.

Common questions

Is the 33% green belt rule still in force?

For older clearances, the condition written in your clearance still applies. For new and pending applications, the 29 October 2025 memorandum sets category-based minimums instead.

What planting density should we use?

The memorandum refers to 2,500 trees per hectare for common green areas in industrial estates. Your clearance may set a density, rows or widths; change the density in the calculator to match.

Can part of the green belt be outside our site?

The memorandum allows planting beyond the minimum to be done off-site, with at least five years of watering and protection. Check what your clearance allows.

Which species should we plant?

Native, pollution-tolerant species in several layers suit most sites. See our green belt guide and confirm the list with the State Forest Department.

Can Grow Billion Trees plant and maintain our green belt?

Yes. We survey the site, plan species, plant with our team, care for the trees for three years and report on GreenTrack. Green belt work is priced per project after a site survey.
