Brazil’s largest energy giant tests Cardano to fix carbon double-counting
Petrobras, Brazil’s state-controlled energy firm, is testing Cardano to observe sustainable aviation gas advantages and stop double-counting.
The Cardano Foundation stated on Sept. 30 that an ongoing analysis and growth collaboration had delivered applications for sustainable aviation fuel (SAF) and Diesel R, Petrobras’ renewable gas model.
The SAF challenge addresses an issue that arises when the customer of a gas’s environmental profit is totally different from the customer or person of the gas itself. Its Book-and-Claim mannequin lets an airline, firm, or passenger obtain that profit even when the SAF is produced or used elsewhere.
Petrobras developed the SAF platform with PUC-Rio University’s Ledger Labs and the Cardano Foundation. According to the Foundation’s case study, it represents SAF environmental attributes as standardized CS-SAF tokens on Cardano.
Those tokens may be created, transferred, checked, and retired. Retirement prevents the identical attribute from being claimed once more, whereas the digital file traces the allocation again to the unique gas certificates.
The crypto analogy is double spending: stopping reuse of a digital asset, utilized right here to an environmental declare.
Travelers can enter departure and vacation spot airports, calculate a CS-SAF allocation and obtain a certificates displaying their route, distance and allocation, the Foundation says. That declare stays linked to the unique SAF certificates.
The tokens carry metadata aligned with CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation.
In guidance published June 16, the Roundtable on Sustainable Biomaterials says Book-and-Claim adjustments neither the bodily gas a purchaser makes use of nor its related emissions. Airlines ought to disclose supported reductions individually from operational emissions.
Different value-chain contributors could make distinct claims, so long as their disclosures don’t misrepresent the general discount.
Cardano utilization past aviation
The Diesel R challenge, developed with PUC-Rio, proposes checkpoints throughout manufacturing, transportation and use. Its intention is a steady fuel-lifecycle file that might assist Scope 3 reporting, which covers oblique emissions throughout an organization’s wider worth chain.
That would join data held by suppliers and logistics suppliers, giving emissions reporting a extra traceable supply-chain historical past. The Foundation describes this structure as a proposed mannequin inside the R&D work.
The SAF platform illustrates how Cardano can file the allocation and retirement of environmental advantages. Commercial use stays unquantified, because the Foundation’s disclosures present no transaction volumes or income figures.
