GFRP rebar GFRP Sustainability — GFRP Rebar and Sustainability — The Carbon Footprint Ad

Construction's Carbon Problem

Every tonne of steel rebar produces approximately 1.8–2.2 tonnes of CO2. India is the world's second-largest steel producer and one of the fastest-growing construction markets.

Embodied Carbon: GFRP vs Steel

8mm TMT Fe500: ~0.71 kg CO2e per metre

8mm GFRP IS 18256: ~0.18–0.22 kg CO2e per metre

Result: GFRP has approximately 70% lower embodied carbon per metre.

The Service Life Multiplier

Steel structures in corrosive environments are rebuilt 2–3 times over 100 years. GFRP is built once. Over 100 years: GFRP has 80–85% lower total embodied carbon per square metre in corrosive environments.

Green Building Certifications

IGBC: Regional materials credit + innovation credits for non-corrosive reinforcement.

LEED India: Materials & Resources credits for regional sourcing.

GRIHA: Lifecycle performance alignment.
