Petrobras Taps Cardano for Blockchain-Based Sustainability Tracking
Brazil's 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. 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 second application creates digital checkpoints to track the production, transportation and use of Diesel R. This data can support Scope 3 reporting, which covers indirect emissions across a company's value chain.
