Petróleo Brasileiro S.A. – Petrobras (NYSE:PBR) has deployed two Cardano (ADA) blockchain applications for sustainable aviation fuel and renewable diesel.

The projects connect fuel certificates, environmental claims, production data and emissions records across fragmented supply chains.

“Public blockchain gives us the opportunity to make that trust part of the system by design, providing industries with a shared, verifiable foundation for the next generation of energy markets,” LATAM Business Development Lead Rafael Fraga said in a statement.

For SAF, CS-SAF tokens represent verified environmental attributes aligned with CORSIA standards and prevent duplicate claims.

Passengers can calculate allocations by route and receive certificates linking their claims to original SAF records.

The Diesel R application creates digital checkpoints across production, transport and use for lifecycle traceability.

The system supports automated minting, transfer and retirement without manual reconciliation, strengthening auditability across stakeholders.

Following the announcement, Petrobras shares were up 1.07% at $20.87.
