Petrobras dey Use Cardano to Trace Renewable Fuels

Petrobras, Brazil’s state-controlled energy company, don develop two blockchain applications through ongoing research and development collaboration, the Cardano Foundation announce on September 30. The projects dey tackle two different challenges: how to track who dey receive the environmental benefit wey relate to sustainable aviation fuel, or SAF, and how to connect production, transportation, and use data for Diesel R, Petrobras’ renewable fuel brand.

Cardano Dey Track SAF Environmental Claims

The SAF project bring together Petrobras, the Cardano Foundation, and Ledger Labs, the blockchain research center for the Pontifical Catholic University of Rio de Janeiro, wey people sabi as PUC-Rio.

Sustainable aviation fuel na lower-carbon alternative to conventional jet fuel wey fit work inside existing aviation infrastructure. The application dey record the environmental benefit wey relate to im use and dey track how dem allocate am.

E dey use Book-and-Claim model, wey separate the physical movement of fuel from the right to claim the benefit. Airline, company, or passenger fit receive allocation even if dem produce or use the SAF for another place.

Cardano dey connect the original fuel certificate to digital record wey show where the benefit originate, who receive am, and whether person don claim am. The system design make e no allow duplicate claims and still preserve the history wey dem need for verification.

Example: passenger fit receive certificate wey link to SAF wey dem use for another place inside the aviation system. The claim go refer to that documented fuel use, without require make the passenger own aircraft use the same fuel.

Passengers Dey Receive Certificates for Individual Journeys

The application get workflow for individual travelers. Passengers go enter their departure and destination airports, and the system go calculate the corresponding amount of CS-SAF, the digital token wey represent the SAF environmental benefit.

The certificate wey come out go record the route, distance wey person travel, and the allocation. Each CS-SAF allocation go link the passenger claim back to the original fuel certificate, so that people fit check the source.

This one give the passenger-facing process clear steps: select journey, calculate the allocation, and receive certificate wey get traceable record behind am.

Diesel R Dey Connect Supply Chain Emissions Data

The second project, wey Petrobras develop with PUC-Rio, apply Cardano to Diesel R. The model wey dem propose create digital checkpoints across production, transportation, and use, to combine information from those stages into continuous fuel lifecycle record.

The approach dey support Scope 3 emissions reporting, wey cover indirect greenhouse gas emissions across company wider value chain. To gather that information, e dey often require records from suppliers, logistics providers, and other organizations wey dey use separate systems.

The Diesel R model intend to connect those records so that people fit check their origins and how dem use am for emissions accounting. Cardano dey provide shared verification layer for information wey for normal situation go sidon across different companies and databases.

Rafael Fraga, LATAM Business Development Lead for the Cardano Foundation, talk say trust for environmental data na requirement for the energy transition.

E emphasize the need to establish where information dey come from, how e dey move, and who fit rely on am as supply chains dey become more complex.

For Diesel R, the intended result na traceable basis for emissions audits. Auditor fit follow reported figure back to the relevant production, transportation, or use record, even when the supporting information dey come from different companies.
