Petrobras Deploys Cardano Blockchain for Renewable Fuel Tracking

Brazil's state-controlled oil company Petrobras has partnered with Cardano to develop two blockchain-based applications for tracking environmental claims tied to renewable fuels. The first application focuses on sustainable aviation fuel (SAF) and tokenizes environmental attributes into digital tokens, designed to prevent double counting of sustainability benefits.

The SAF tool follows a Book-and-Claim structure that decouples environmental benefits from the physical fuel, allowing buyers to allocate benefits even when SAF is consumed elsewhere. The system carries metadata aligned with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) and enables passengers to claim tokens through an application.

The second application targets Petrobras' renewable diesel fuel, creating digital checkpoints to track production, transportation, and use of Diesel R. This data can be used to support Scope 3 reporting on indirect emissions across a company's value chain.
