Summary
Brazil’s state-controlled energy company Petrobras is testing the Cardano blockchain in two research projects to trace environmental claims related to sustainable aviation fuel and partly renewable Diesel R. The aviation project aims to prevent double counting of emissions reductions by tracking the ownership and claims of fuel benefits, while the diesel project seeks to record the fuel’s production, transportation, and use. Both projects remain in the research phase with no timelines or volumes disclosed.
Why it matters
The source indicates these projects could improve transparency and traceability of emissions reduction claims, important for environmental reporting and market integrity. The aviation project addresses challenges in the book-and-claim model, preventing companies from claiming the same environmental benefit twice. The source does not provide further analysis on broader market or policy impacts.
Key context
The aviation fuel project helps airlines link emissions reductions to passengers’ flight paths by issuing certificates relatable to original fuel benefits. The diesel project aims to support Scope 3 emissions reporting, where companies need data from upstream suppliers. Brazil has been an active adopter of Cardano technology, with Petrobras joining other government and industry users in the region.
Key numbers and entities
Petrobras, Brazil’s state oil company, and the Cardano Foundation are involved. Frederik Gregaard, CEO of the Cardano Foundation, commented on Petrobras’s adoption. Cardano recently joined the x402 payment standard, though commercial use of this technology is still pending.
What remains unclear
The source does not specify when these projects might expand beyond research, what volumes of sustainable fuels might be involved, or exact details of the technical implementation. It also does not clarify potential regulatory recognition or integration with other emissions tracking systems.
