  "account": "Brazilian oil giant Petrobras has utilized Cardano technology to create two applications aimed at verifying sustainability claims related to sustainable aviation fuel (SAF) and renewable diesel fuel. This research collaboration with PUC-Rio’s Ledger Labs commenced in 2023 and expanded in 2025. The first application tokenizes the environmental attributes of SAF into digital tokens, employing a Book-and-Claim model to prevent double claims. These tokens, labeled CS-SAF, contain metadata that aligns with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). Additionally, passengers can claim CS-SAF tokens and receive certificates tied to their journey. The second application involves digital checkpoints for Diesel R, Petrobras' renewable diesel fuel, supporting Scope 3 reporting, which includes indirect emissions. The projects are part of a broader research and development initiative, with the Cardano Foundation not disclosing specific fuel volumes or deployment timelines.",
