Petrobras Uses Cardano to Track SAF Claims
The Cardano Foundation says Brazilian oil company Petrobras has begun using the blockchain to record sustainable aviation fuel environmental attributes.
Updated on Nov. 8, 2026 in Oil and Gas
Petrobras has started using Cardano to track sustainable aviation fuel claims, recording the fuel's environmental attributes as transferable digital tokens. The tokens carry CORSIA-aligned metadata and can be issued, transferred, queried, or retired.
Why it matters
The tracking is intended to lower the risk that separate companies claim the same emissions benefit from one batch of fuel. Verifiable records of this kind may matter as aviation emissions rules increasingly depend on documented fuel attributes.
No quantitative figures were disclosed for the Petrobras deployment, including tracked volumes or token counts. The source does not state how many SAF batches are covered or how the system's scale compares with existing certification registries.
The players
Petrobras
Petrobras is the Brazilian state-controlled oil and gas company that is deploying the system to track its sustainable aviation fuel claims.
Cardano Foundation
The Cardano Foundation is the nonprofit body that promotes the Cardano blockchain and co-developed the tracking system with Petrobras.
PUC-Rio University's Ledger Labs
Ledger Labs is a research group at Pontifícia Universidade Católica do Rio de Janeiro that helped develop the system alongside Petrobras and the Cardano Foundation.
The details
The system represents each fuel's environmental attributes as digital tokens that remain linked to the SAF through production, shipment, and use. Each token carries CORSIA-aligned data fields, and Petrobras and the Cardano Foundation developed the system with PUC-Rio University's Ledger Labs.
Timeline
The Cardano Foundation announced on November 8, 2026 that Petrobras had begun using the system.
Market Landscape
Aviation operators face growing pressure to prove that claimed emissions reductions from sustainable aviation fuel are not double-counted across buyers. Petrobras's use of CORSIA-aligned tokens on Cardano applies the international aviation offsetting scheme to a digital record of individual fuel attributes.
For travelers and businesses that buy airline tickets or cargo space, verified sustainable fuel records could eventually affect how emissions claims are reported and priced. The system's tokens are meant to prevent the same environmental benefit from being counted twice by different parties.
The takeaway
Blockchain-based tracking is one attempt to make sustainable aviation fuel claims verifiable across the supply chain. Whether the approach scales beyond a single operator will depend on whether other producers and airlines adopt compatible records.
