Problem
Airlines and aviation companies need to demonstrate verifiable Scope 3 emissions reductions from Sustainable Aviation Fuel, but existing SAF credit markets often rely on paper-based claims without a direct link to physical fuel batches, making audits and CDP reporting difficult.
Solution
GSC offers book‑and‑claim certificates for Sustainable Aviation Fuel that are directly tied to physical SAF batches recorded on refinery mass‑balance ledgers. Each certificate includes per‑batch carbon‑intensity metrics, feedstock type, production pathway, and geography, and is retired on a public registry with a unique ID. The certificates meet ISCC EU and CORSIA standards, allowing customers to cite them in CDP filings and audit processes. GSC operates the Global SAF Stack—a self‑hosted mass‑balance engine and registry—providing an end‑to‑end, audit‑ready chain of custody from feedstock to retirement. This infrastructure ensures that purchased credits represent real, delivered fuel rather than unbacked claims.
Target Audience
Primary customers are airlines, aviation fuel purchasers, and corporate sustainability teams that need credible SAF credits to meet regulatory, reporting, and investor requirements.
