Brazil’s Petrobras uses Cardano to track sustainable aviation fuel, renewable diesel

Brazilian state-controlled oil company Petrobras has developed two blockchain applications using Cardano to track sustainability data for sustainable aviation fuel (SAF) and its Diesel R renewable fuel.According to a Wednesday announcement from the Cardano Foundation, the first application, developed with PUC-Rio’s Ledger Labs, tokenizes environmental attributes associated with SAF into digital tokens designed to prevent the same claim from being used more than once.The application uses a Book-and-Claim model, which allows the environmental benefit to be separated from the physical fuel and assigned to an airline, company or passenger even if the SAF is used elsewhere.The tokens, known as CS-SAF, contain metadata aligned with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). Passengers can also claim CS-SAF tokens through an application and receive a certificate tied to their journey and associated environmental claim.Source: Cardano FoundationThe second application creates digital checkpoints to track the production, transportation and use of Diesel R, Petrobras’ renewable diesel fuel. The Cardano Foundation said the data could support Scope 3 reporti...
