ADA Advancing Regulated Asset Tokenization as Brazil’s Petrobras Brings Sustainable Aviation Fuel Certificates to Cardano

Brazil’s state-controlled energy company Petrobras has begun using the Cardano blockchain to track environmental claims linked to its sustainable aviation fuel, according to a Wednesday report from the Cardano Foundation. The system converts the fuel’s environmental attributes into digital tokens intended to prevent the same claim from being used more than once, addressing double-counting in carbon markets. By tracking the fuel through production, shipment and use, it aims to improve supply-chain traceability and emissions reporting. The Cardano Foundation had said in late September that Petrobras was testing the blockchain.
