Brazilian state-controlled oil firm Petrobras has developed two blockchain purposes utilizing Cardano to trace sustainability knowledge for sustainable aviation gasoline (SAF) and its Diesel R renewable gasoline.
In line with a Wednesday announcement from the Cardano Basis, the primary utility, developed with PUC-Rio’s Ledger Labs, tokenizes environmental attributes related to SAF into digital tokens designed to forestall the identical declare from getting used greater than as soon as.
The applying makes use of a Guide-and-Declare mannequin, which permits the environmental profit to be separated from the bodily gasoline and assigned to an airline, firm or passenger even when the SAF is used elsewhere.
The tokens, referred to as CS-SAF, comprise metadata aligned with the Carbon Offsetting and Discount Scheme for Worldwide Aviation (CORSIA). Passengers may declare CS-SAF tokens via an utility and obtain a certificates tied to their journey and related environmental declare.

The second utility creates digital checkpoints to trace the manufacturing, transportation and use of Diesel R, Petrobras’ renewable diesel gasoline. The Cardano Basis mentioned the info might help Scope 3 reporting, which covers oblique emissions throughout an organization’s worth chain.
The tasks are a part of an ongoing analysis and improvement collaboration that began in 2023 with blockchain training for Petrobras workers and expanded in 2025 to energy-sector analysis with PUC-Rio’s Ledger Labs. The Cardano Basis didn’t disclose gasoline volumes lined by the purposes or a timeline for broader deployment.

Blockchain finds use in sustainable aviation gasoline monitoring
Shell has additionally used blockchain to trace environmental attributes related to sustainable aviation gasoline via Avelia, a Guide-and-Declare platform launched in 2022 that makes use of blockchain to trace claims and stop double counting.
In a September update, Shell mentioned Avelia had contributed to greater than 84 million gallons of SAF getting into the worldwide gasoline community since its launch in 2022, leading to greater than 780,000 tonnes of CO₂e abatement via June 2026.
Extra not too long ago, Australia’s Viva Power signed an settlement with NoviqTech in January to analysis digital Guide-and-Declare techniques for sustainable aviation gasoline, together with how blockchain might help emissions reporting and observe environmental claims.
