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

Odaily News: Brazilian state-owned oil company Petrobras is testing the Cardano blockchain in two research projects to track environmental claims related to sustainable aviation fuel and partially renewable Diesel R.

The aviation fuel project aims to prevent companies from double-counting the same emissions reductions; the Diesel R project will record fuel production, transportation, and usage stages to support emissions reporting. Both projects are still in the research phase, and no timeline for expanded deployment or the scale of fuel coverage has been disclosed. (CoinDesk)
