Petrobras Tests Cardano Blockchain to Track Sustainable Aviation Fuel and Diesel R

Odaily Planet Daily News – Petrobras, the Brazilian national oil company, is testing the Cardano blockchain in two research projects to track sustainable aviation fuel and environmental claims related to partially renewable Diesel R. The aviation fuel project aims to prevent companies from double-counting the same emission reductions, while the Diesel R project will record fuel production, transportation, and usage processes to support emission reporting. Both projects are still in the research phase, and no timeline or scale for expanded deployment has been disclosed yet. (CoinDesk)
