Petrobras Tests Cardano for Sustainable Aviation Fuel Tracking

Petrobras has collaborated with the Cardano Foundation and PUC-Rio's Ledger Labs to develop two research-stage applications for tracking environmental claims related to sustainable aviation fuel (SAF) and diesel. The projects are part of an ongoing research collaboration between Petrobras, the Cardano Foundation, and PUC-Rio.

The Book-and-Claim model under the SAF project allows airlines to receive environmental benefits associated with SAF, even when another operator uses the physical fuel. Digital tokens representing these benefits can be tracked and verified against recognized standards such as CORSIA. Once verified, the certificates become standardized tokens carrying information about their environmental attributes.

For passengers, an application calculates a corresponding SAF allocation based on departure and destination airports and provides a certificate showing the route, distance, and allocation, with a connection to the original fuel certificate. The digital token representing the aviation fuel's environmental benefit is called CS-SAF.
