Its Book-and-Claim model lets an airline, company, or passenger receive that benefit even when the SAF is produced or used elsewhere.<\/p>\n<p>Petrobras developed the SAF platform with PUC-Rio University&#8217;s Ledger Labs and the Cardano Foundation. According to the Foundation&#8217;s case study, it represents SAF environmental attributes as standardized CS-SAF tokens on Cardano.<\/p>\n<p>Those tokens can be created, transferred, checked, and retired. Retirement prevents the same attribute from being claimed again, while the digital record traces the allocation back to the original fuel certificate.<\/p>\n<p>The crypto analogy is double spending: preventing reuse of a digital asset, applied here to an environmental claim.<\/p>\n<p>Travelers can enter departure and destination airports, calculate a CS-SAF allocation and receive a certificate showing their route, distance and allocation, the Foundation says. That claim remains linked to the original SAF certificate.<\/p>\n<p>The tokens carry metadata aligned with CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation.<\/p>\n<aside id=\"cs-inline-newsletter-1\" class=\"cs-inline-newsletter\" data-inline-newsletter=\"\" data-newsletter-placement=\"article-midpoint\" data-newsletter-pending-label=\"Joining\u2026\" data-newsletter-pending-status=\"Joining The Catalyst\u2026\" data-newsletter-email-required-message=\"Before sending, please provide your email address.\" aria-labelledby=\"cs-inline-newsletter-1-title\" aria-describedby=\"cs-inline-newsletter-1-copy\">\n<div class=\"cs-inline-newsletter__inner\">\n<div class=\"cs-inline-newsletter__content\"> <span class=\"cs-inline-newsletter__eyebrow\"> <i class=\"fa-regular fa-envelope\" aria-hidden=\"true\"\/> The Catalyst <\/span><\/p>\n<h2 id=\"cs-inline-newsletter-1-title\" class=\"cs-inline-newsletter__title\">What\u2019s moving crypto.

Its aim is a continuous fuel-lifecycle record that could support Scope 3 reporting, which covers indirect emissions across a company&#8217;s wider value chain.<\/p>\n<p>That would connect information held by suppliers and logistics providers, giving emissions reporting a more traceable supply-chain history. The Foundation describes this architecture as a proposed model within the R&amp;D work.<\/p>\n<p>The SAF platform illustrates how Cardano can record the allocation and retirement of environmental benefits. Commercial use remains unquantified, as the Foundation&#8217;s disclosures provide no transaction volumes or revenue figures.<\/p>\n<\/div>\n<p>Adoption,Enterprise,Featured,Tokenization,Cardano,Cardano Foundation,regulationCardano,Cardano Foundation,regulation#Brazils #largest #energy #giant #tests #Cardano #fix #carbon #doublecounting1790808349<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Petrobras, Brazil&#8217;s state-controlled energy company, is testing Cardano to track sustainable aviation fuel benefits and prevent double-counting.
