Our Mission: Make Sustainable Materials the Default, Not the Exception

The construction industry is responsible for 39% of global carbon emissions. We can't solve climate change alone — but together, we can make a dent.


GreenChainz exists to make verified sustainability data as accessible as product pricing. No more hunting through PDFs. No more fragmented research. No more greenwashing.


Every architect, contractor, and manufacturer on this platform is part of the solution. You're not just sourcing materials — you're voting for a livable planet with every RFQ you send.


This is bigger than any one company. This is our home. This beautiful blue and green planet. And the only way out of this mess is if we all work together.

How It Works

🔍 For Architects & Contractors

Search and filter sustainable materials by EPDs, certifications (LEED, FSC, Cradle to Cradle), embodied carbon, and recycled content. Compare products side-by-side and send RFQs directly to suppliers.

🏭 For Suppliers

Showcase your sustainable products to qualified buyers. Upload EPDs, certifications, and product specs. Receive RFQs from architects actively sourcing materials.

✅ Verified Sustainability Data

Every product's sustainability claims are founder-verified. We integrate with EPD International, Building Transparency (EC3), and leading certification bodies.
