ADA news: Cardano tapped by Brazil’s state oil giant to track cleaner jet fuel and diesel
- On Wednesday, Petrobras announced two blockchain research projects on Cardano to track environmental claims for sustainable aviation fuel and renewable diesel, developed with the Cardano Foundation and Pontifical Catholic University .
- The collaboration aims to make sustainable fuel data auditable and verifiable for airlines and passengers seeking green fuel proof. Rafael Fraga, LATAM business development lead at the Cardano Foundation, said public blockchain builds trust by design.
- One tool uses a Book-and-Claim model for sustainable aviation fuel, issuing standardized CS-SAF tokens on Cardano that decouple environmental benefits from physical fuel, allowing airlines to claim reductions aligned with CORSIA standards.
- A second proposed model targets Diesel R, recording production and transportation checkpoints to build a complete lifecycle history, helping companies report indirect Scope 3 emissions while preventing double counting of environmental benefits.
- Both initiatives remain in the research phase with no announced timeline for commercial use, extending a relationship that began in December 2023 when the Cardano Foundation launched blockchain workshops for more than 40,000 Petrobras University employees.

ADA news: Cardano tapped by Brazil’s state oil giant to track cleaner jet fuel and diesel
Petrobras is testing the blockchain in two research projects aimed at preventing emissions benefits from being counted twice and tracing fuel data across production and use.
Petrobras Deploys Cardano to Trace SAF and Renewable Diesel in Brazil
Brazil’s state-controlled oil company Petrobras says it has built two blockchain-based applications using Cardano to help track environmental claims tied to renewable fuels. The projects focus on preventing “double counting” of sustainability benefits while improving traceability across fuel production and usage. According to an announcement from the Cardano Foundation published Wednesday, the first application tokenizes [...]
Petrobras, the energy company controlled by the Brazilian State, experiments the tracking of fuel on blockchain Cardano to verify its promises on fuels with low carbon impact. This is confirmed by two research projects announced on 30 September 2026 by the Cardano Foundation, which describes the initiative as an initial step but significant for traceability on-chain in [...]
Cardano Foundation Backs Bold Petrobras Renewable Fuel Traceability with Blockchain
TL;DR Cardano Foundation announced two initiatives with Petrobras for blockchain traceability of sustainable aviation fuel and renewable diesel. The Book-and-Claim model separates the environmental benefit from the physical fuel and allows it to be assigned to airlines, companies, or individual passengers. The second project applies digital checkpoints to the Diesel R lifecycle to strengthen scope ...
