Petrobras tests Cardano, tracking sustainable aviation fuel and diesel

According to CoinDesk, Brazil's state-controlled energy company Petrobras is testing the Cardano blockchain to track statements related to low-carbon fuels.

The Cardano Foundation announced two research projects on Wednesday, one focusing on sustainable aviation fuel, which is a low-carbon aviation fuel alternative that can be used in existing aircraft and airports, and the other on Diesel R, which is diesel produced by Petrobras using renewable materials such as vegetable oils and animal fats.

The aviation fuel project targets the book-and-claim model in green fuel sales: airlines can pay for the environmental benefits of sustainable fuel, even if the fuel itself is used elsewhere. This model requires recording the benefit attribution and claiming time to avoid double counting the same emissions reduction.

The application records the source, recipient, and claiming time of each benefit through Cardano. In real scenarios, passengers can input their departure and destination airports to calculate the corresponding fuel benefits and receive a certificate linking their quota to the original fuel certificate. The diesel project records information on fuel production, transportation, and usage, compiling it into a complete fuel process history, which helps companies report Scope 3 emissions.

Frederik Gregaard, CEO of the Cardano Foundation, stated that Brazil has been one of the most stable adopters of Cardano, from government agencies like SERPRO to industrial sectors like SENAI, and Petrobras continues to value the on-chain traceability and transparency.

He mentioned that with x402 landing on Cardano and Fireblocks increasing support for Cardano native tokens, institutional interest continues to grow.
