Cardano Foundation teams with Petrobras on blockchain projects for SAF and Diesel R
These initiatives address different parts of the renewable fuel lifecycle. For SAF, Cardano connects a physical fuel certificate to a digital record of the associated environmental gains, creating a clear trail from the original certificate through to the final claim. For renewable diesel, the technology links information across production, transportation and use, improving visibility over the fuel journey and the emissions-related data associated with it.
The SAF R&D project brings together Petrobras, PUC-Rio through its blockchain center Ledger Labs, and the Cardano Foundation. Sustainable aviation fuel is a lower-carbon alternative to conventional jet fuel that can be used within existing aviation infrastructure. As adoption grows, airlines and passengers also need credible ways to verify the environmental benefit associated with its use.
The project uses a Book-and-Claim model, which separates that environmental benefit from the physical fuel itself. This allows the benefit to be assigned to an airline, company or passenger even when the SAF is produced or used elsewhere. Cardano provides the traceable record behind the process, showing where the benefit originated, who it was assigned to and that it has only been claimed once.
The application also extends to individual passengers. Travelers can enter their departure and destination airports, calculate the corresponding CS-SAF amount – the digital token used to represent the SAF environmental benefit – and receive a certificate recording their route, distance traveled and allocation. This links the passenger’s claim back to the original SAF certificate.
