Cardano Foundation and Petrobras, in collaboration with PUC-Rio University, have developed a blockchain system that tokenizes sustainable aviation fuel (SAF) attributes to create verifiable environmental claims in Brazil's growing SAF market. The tokens, based on the Cardano blockchain, represent SAF attributes aligned with international carbon offset standards and can be transferred or retired using a Book-and-Claim model. Petrobras began delivering SAF at Rio de Janeiro’s airport in December 2025, aiming to reduce aviation emissions significantly. This initiative enhances trust and transparency in the energy transition by linking blockchain technology with renewable fuel certification and passenger offset claims.
