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

Petrobras developed two Cardano-based applications to track sustainability claims tied to aviation fuel and renewable diesel as part of an ongoing research collaboration.

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.
