150,000 tonnes of physical SAF moved by our founding team
SAF & SAFc transaction advisory
Transactions Backed by Real Fuel
GSC advises producers and buyers on SAF and SAFc transactions. We structure the commercial terms, introduce the counterparty, and assemble the compliance documentation — so the certificate you retire is anchored to a physical SAF batch that actually moved through a known refinery's mass-balance ledger, not paper attribution. Settlement is principal-to-principal between you and your counterparty; GSC never takes title.
Real, delivered SAF
Every transaction we advise is anchored to a physical batch on a refinery's mass-balance ledger. We help you trace each tonne from feedstock to delivery before the producer issues the certificate.
ISCC EU + CORSIA-eligible
Structured against certification standards your auditor and CDP filing already recognise. No bespoke scheme, no methodology you have to defend internally.
Audited retirement
Each certificate is retired on an established third-party registry of record, with a public retirement ID you can cite directly in disclosures, supplier responses, and CDP submissions.
Feedstock & CI disclosed
Per-batch carbon-intensity score (gCO2e/MJ), feedstock type, production pathway, and geography. No black boxes — the attributes your sustainability team needs are on the certificate.
Three Steps, Forty-Eight Hours
A typical SAFc transaction moves fast. Most buyers go from first call to indicative terms within two business days.
Scope
Tell us your volume, vintage, retirement window, and any preference on CI score or feedstock. A 20-minute call is usually enough.
Match
Within 48 hours we come back with indicative terms sourced across our refiner and producer network. You contract directly with the counterparty — GSC structures the deal and never sits on the title or the funds.
Retire
The producer issues the certificate and it is retired on an established third-party registry of record. We support you through issuance and retirement, and hand over the documentation for your reporting and audit file.
A Fuel Network, Not a Paper Marketplace
Most SAFc you can buy today comes from intermediaries with no physical fuel relationships and no view of the underlying batch. GSC is the other kind of advisor.
The advice comes from moving real fuel
The founding team has moved 150,000 tonnes of physical SAF — built on years of relationships with refiners, producers, and aviation fuel distributors. Every transaction we advise draws on that network, not a paper marketplace.
Software that keeps your audit file straight
GSC gives clients record-keeping software — the Global SAF Stack, built by Thalassis — to document and report their own SAF and SAFc activity. Certificates are issued and retired on established third-party registry infrastructure; the Stack is your evidence layer on top of it, not the registry.
Scope 3 Is Tightening Faster Than Supply
CSRD reporting expectations, SBTi target-setting, and CDP disclosure scoring now all reward credible aviation emissions accounting. For most disclosing companies, business travel and freight are the hardest line items to address — and SAFc is the only book & claim mechanism that maps cleanly onto them.
The market is moving from voluntary to expected inside 24 months. Available SAFc supply is finite and concentrates in a small number of vintages. Buyers who scope and lock volumes early get the CI scores and prices they want. Buyers who wait take what's left.
Lock the vintage. Retire on schedule. Disclose with evidence.
