Petrobras Deploys Cardano-Based Blockchain Apps for Sustainable Fuel Tracking

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.

The first application, developed with PUC-Rio's Ledger Labs, tokenizes environmental attributes associated with SAF into digital tokens that prevent the same claim from being used more than once.

This Book-and-Claim model 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).

Petrobras' second application creates digital checkpoints to track the production, transportation, and use of Diesel R.
