Scope4 — Blockchain-secured, AI-verified CBAM compliance. No greenwashing. No spreadsheets. Just cryptographic truth.

The European Union's Carbon Border Adjustment Mechanism (EU Regulation 2023/956) requires every EU importer of steel, cement, aluminium, and fertilisers to report the exact production-embedded carbon emissions of each shipment and purchase CBAM certificates from 2026 onward. Today, most companies handle this with self-reported PDFs, email chains, and spreadsheets — a system where greenwashing is trivially easy and independent verification is impossible.

Scope4 is a B2B compliance platform that solves this by combining three layers: multi-party blockchain attestation on Solana, a deterministic AI agent pipeline, and a real-time compliance dashboard.

How it works: Three parties independently attest to the shipment — the Seller declares the production emissions intensity and facility reference, the Importer declares the shipment quantity and invoice details, and the Logistics Partner confirms the cargo weight and route. All three attestations are sealed on Solana as immutable on-chain records via a custom Anchor smart contract. Only when all three parties have signed does the AI pipeline trigger automatically.

The AI pipeline uses a neuro-symbolic architecture. The Validation Agent (pure TypeScript, no LLM) cross-checks the three inputs — if the seller's declared weight and the logistics partner's confirmed weight differ by more than 5%, it flags a trust score downgrade. The Calculation Agent (pure TypeScript, no LLM) computes CBAM tax exposure using official EU Commission default emission factors, with a legally required strict separation between production-embedded emissions (CBAM liable) and transport emissions (internal analytics only). The Reporting Agent (Gemini 2.5 Flash) then generates a professional, legally-structured compliance report — complete with a blockchain methodology statement and an official digital signature — that is designed to replace old-school paper audit certificates.

We deliberately keep AI away from the math. A CBAM calculation wrong by 3% due to an LLM hallucination is a legal liability. So Gemini is used only for what it excels at: writing professional, human-readable summaries from hard mathematical facts.

The result is a compliance pipeline where the Solana blockchain guarantees that no party silently altered the data, and AI ensures the regulatory analysis is fast, neutral, and auditable. Scope4 directly supports the EU's Net Zero by 2050 goal by making CBAM enforcement accurate, tamper-proof, and scalable.
