Petrobras tests Cardano to track cleaner jet fuel and diesel

Brazil's state-controlled oil giant Petrobras is testing Cardano in research projects to trace cleaner fuels through its supply chain, using $ADA to prevent double-counting of sustainable aviation fuel credits and verify renewable diesel production. The pilots put fuel supply-chain provenance on a public blockchain so emissions benefits can be checked without being counted twice — a core integrity problem in carbon-credit accounting.

• The effort adds to Cardano's growing enterprise adoption beyond payments, in supply-chain and real-world-asset tracking.
• No scope details or rollout timeline beyond the two pilot projects were disclosed.
