Scope 3 Is Where Climate Commitments Break Down
Steel, cement, ammonia, long-haul trucking, and critical minerals dominate corporate emissions, but direct supplier engagement alone can't deliver reductions fast enough or far enough upstream.
Companies need a credible way to support decarbonization beyond Tier-1 suppliers without rebuilding their entire procurement stack.
A Tier-2-N Solution for Scope 3 Category 1 Emissions
S3 Markets enables buyers to support verified low-carbon production through Environmental Attribute Certificates (EACs) tied directly to industrial output.
EACs complement supplier engagement by creating demand signals and revenue for upstream decarbonization, where emissions are highest and alternatives are limited.
How S3 Markets Works
Step 2
S3 Issues Blockchain-Verified EACs
Each tonne of low-carbon production generates a traceable, auditable EAC.
Step 3
Buyers Purchase & Retire EACs
Enterprises use EACs to support real Scope 3 reductions.
Step 4
Capital Flows to Decarbonization
Contracted EAC demand improves project bankability and lowers cost of capital.
Real-World Use Cases Across Industrial Supply Chains
