Petrobras Tests Cardano for Sustainable Fuel Tracking

Brazilian energy giant Petrobras is testing the Cardano blockchain to track low-carbon fuel claims, according to the Cardano Foundation. The pilot projects focus on sustainable aviation fuel and renewable diesel, using a book-and-claim model to record environmental benefits and prevent double-counting. The system tracks the origin, recipient, and timing of fuel credits, allowing for transparent emissions reporting. Cardano Foundation CEO Frederik Gregaard noted that Brazil remains a key adopter of the network, with institutional interest growing alongside recent integrations like Fireblocks support for Cardano native tokens.
