Petrobras Leverages Cardano Blockchain for Renewable Fuel Tracking

Petrobras, Brazil's state-controlled oil company, has developed two blockchain-based applications using Cardano to track environmental claims tied to renewable fuels.

The first application tokenizes sustainability benefits associated with sustainable aviation fuel (SAF) and ties those attributes to the Book-and-Claim model commonly used in the sector.

A second application focuses on renewable diesel, creating digital 'checkpoints' intended to support reporting of indirect emissions along a company's value chain.
