Azzera has incorporated Energy Web's Verified Compute Cloud into its SAF Proof of Delivery platform, giving operators SAF compliance claims that any auditor or regulator can independently retrace. The Verified Compute Cloud produces tamper-proof records of every calculation, so results can be confirmed without trusting the system that generated them. For operators, weeks of audit prep become evidence verifiable on demand.

As ReFuelEU Aviation, EU ETS, UK ETS and ICAO CORSIA push sustainable aviation fuel from voluntary to mandatory, operators face a problem regulation did not solve: turning multi-format Proofs of Compliance from fuel suppliers into auditable emissions claims. Administrative effort returns less per claim as SAF volumes grow and infrastructure has lagged behind. Azzera's Celeste platform already supports over 45 operators and more than 700 aircraft tails across Europe and North America, tracking in excess of 500,000 flights and five million tonnes of emissions.

“We built SAF POD because the gap between SAF regulation and SAF infrastructure was widening, not closing,” says Puja Mahajan, CEO of Azzera. “Operators were being asked to substantiate emissions claims with tools built for invoicing. SAF POD treats compliance as a data problem and solves it at the data layer.”

The integration follows a joint pilot targeting three weaknesses in SAF claims: evidence not uniquely identifiable across documents, emission factors and formulas that cannot be independently retraced and calculations auditors cannot deterministically re-run. The Verified Compute Cloud addresses all three. Two European aviation emissions verifiers, Normec Verifavia and ETS Verification GmbH, joined the pilot to shape verification logic, evidence packages and auditor access protocols inside SAF POD.

“Trust and transparency are foundational to scaling sustainable aviation fuel markets,” adds Katy Lohmann, CCO of Energy Web. “Our collaboration with Azzera demonstrates how trusted digital infrastructure and verifiable computing can help establish confidence in SAF-related data, compliance processes and environmental claims.”

For operators reporting under ReFuelEU, EU ETS, UK ETS and CORSIA, the result is fewer manual reconciliations, lower disqualification risk and FEETS-eligible claims drawn from verified data. The beta programme is open to 10 operators for two months at no cost.
