Petrobras tests Cardano, tracking sustainable aviation fuel and diesel

Petrobras, the Brazilian state-controlled energy company, 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 emission 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 the production, transportation, and use of fuel, compiling it into a full-process history of the fuel, which helps companies report Scope 3 emissions.

Frederik Gregaard, CEO of the Cardano Foundation, stated that Brazil has consistently been one of the most stable adopters of Cardano, from government agencies like SERPRO to the industrial sector like SENAI. Petrobras continues to value the benefits of on-chain traceability and transparency. He mentioned that with the launch of x402 on Cardano and Fireblocks increasing support for Cardano native tokens, institutional interest continues to grow.
