S3 Markets connects you with verified low-carbon producers of ammonia, steel, cement, copper, and other industrial materials-delivering auditable, blockchain-backed Environmental Attribute Certificates (EACs) that count toward Tier-2-N Scope 3 Category 1 purchased goods and services.
Supplier engagement alone cannot deliver the near-term Scope 3 reductions required by modern climate commitments. S3 Markets provides a standardized, defensible mechanism to support upstream industrial decarbonization-giving you access to EACs tied to real production from vetted low-carbon producers.
Buyers use S3 EACs to demonstrate measurable emissions reductions, support producer transition pathways, strengthen climate disclosure and audit readiness, and accelerate progress toward net-zero without upending procurement plans.
S3 gives you a tool to affect emissions far upstream, where your procurement leverage is limited but your footprint is large. Our EACs represent verified low-carbon output from producers you may not directly contract with-complementing direct supplier engagement.
Every EAC is minted, allocated, and retired on a tamper-proof blockchain ledger using ERC-1155 smart contracts. This provides transparent chain of custody, a clear link between production and claims, audit-ready documentation, and confidence for sustainability, finance, legal, and assurance teams.
EACs from green ammonia producers support verifiable emissions reductions across fertilizer, refrigeration, processing, and chemical inputs-where Scope 3 intensity is under increasing scrutiny.
See Food & Beverage pageData centers, warehouses, stores, EVs, and construction rely on emissions-intensive steelmaking. S3 EACs let you support breakthrough steel technologies without renegotiating existing procurement channels.
See Technology pageCement contributes roughly 7% of global CO2 emissions. Procure EACs from producers using carbon-mineralized, low-clinker, or novel processes to demonstrate real progress on embodied carbon.
See Construction & Real Estate pageSupport lower-carbon extraction and refining pathways that reduce embedded emissions in PCs, servers, EVs, and renewable system components.
See Automotive pageStep 1
Choose EACs representing cleaner ammonia, steel, cement, copper, or other materials aligned with your most material Scope 3 categories.
Step 2
Buyers receive EACs in the S3 custodial system, with every transaction traced on-chain.
Step 3
Once allocated and paid, EACs can be retired-supporting credible climate reporting aligned with annual disclosures.
Step 4
S3 provides standardized, compliant materials for internal audit, external assurance, and ESG reporting.
Unlike offsets or generic certificates, S3 EACs are grounded in real production, real MRV, and a transparent digital infrastructure. We verify production, validate emissions, and ensure that every attribute has a defensible chain of custody from producer to buyer.
Designed with MIT engineering principles and built for global enterprises, S3 blends technical depth, blockchain architecture, and industrial decarbonization expertise to deliver credible Scope 3 solutions.
No-S3 is a complementary tool that enables deeper upstream decarbonization where your direct influence is limited.
Yes. Our EACs are designed to reflect real emissions reductions in purchased goods, aligned with leading guidance for emissions-intensive sectors.
Every transaction is recorded on-chain and accompanied by standardized MRV documentation.
