Cardano Foundation and Petrobras Launch Blockchain Applications for Sustainable Fuels
The Cardano Foundation has announced a significant partnership with Brazilian state oil company Petrobras, focusing on the development of two blockchain applications designed to improve the sustainability and traceability of fuel supply chains in Brazil.
This collaboration marks an evolution from an initial educational initiative that began in December 2023, aimed at training Petrobras' employees on blockchain technology. The education program, which included the issuance of evolving NFTs as credentials to the first 500 participants, has now expanded into practical applications targeting sustainable aviation fuel (SAF) and renewable diesel.
Applications Overview
The first application will tokenize the SAF supply chain, creating immutable records that detail the fuel's origin, processing, and logistics. The second application is a decentralized app (dApp) that incentivizes airline passengers flying on SAF-powered routes, promoting consumer participation in sustainable fuel adoption.
As of November 2025, the partnership has progressed to active development, with plans for an incentive system to encourage the use of SAF. Additionally, a Proof of Atenas system has been developed to verify employee training and participation through NFC cards and 3D-printed totems, with pilot runs already conducted.
Significance of the Partnership
This collaboration is particularly noteworthy as it represents Cardano's first governmental partnership in Latin America, given Petrobras' majority state ownership. The initiatives aim to combat greenwashing and enhance transparency in Brazil's energy sector, aligning with the country's goal of meeting 100% of its domestic SAF demand by 2027 to 2029.
