Brazil's Petrobras Uses Cardano to Track Sustainable Fuel

TechFlow reports that on October 1, according to Cointelegraph, Brazil's state-owned oil enterprise Petrobras announced the development of two applications on the Cardano blockchain to track sustainability data for sustainable aviation fuel (SAF) and renewable diesel. This initiative is the result of a research collaboration between the company and PUC-Rio's Ledger Labs that has been underway since 2023.

The application for sustainable aviation fuel adopts a Book-and-Claim model, which tokenizes environmental attributes to ensure that carbon emission reduction benefits are not double-counted or misused; the other application establishes digital checkpoints for renewable diesel, aiming to track its production and transportation processes to support the company's Scope 3 indirect emissions reporting. To date, the project developers have not disclosed specific details regarding the fuel coverage scale or a timeline for large-scale deployment.
