The other covers Diesel R, Petrobras\u2019 diesel made partly from renewable materials such as vegetable oils or animal fats.<\/p>\n<p>\u201cBrazil has been one of the most consistent adopters of Cardano, from SERPRO in government to SENAI in industry. It&#8217;s great to see Petrobras, one of the largest firms in the region, continue to see value in on-chain provenance and traceability,\u201d Frederik Gregaard, chief executive of the Cardano Foundation, told CoinDesk.<\/p>\n<p>\u201cInstitutional interest in Cardano keeps growing, especially with x402 arriving on Cardano and Fireblocks adding support for Cardano Native Tokens. It&#8217;s never been a better time for enterprises to consider what this technology offers,\u201d Gregaard added.<\/p>\n<p>The aviation project tackles a problem with how green fuel is sold. Under a model known as book-and-claim, an airline can pay for the environmental benefit of sustainable fuel even if the fuel itself is used elsewhere.<\/p>\n<p>That arrangement needs a record of who owns the benefit and when it has been claimed, so two companies cannot count the same emissions reduction.<\/p>\n<p>The application uses Cardano to record where each benefit originated, who received it and when it was claimed, helping prevent it from being counted twice.<\/p>\n<p>In the real world, a passenger can enter their departure and destination airports, calculate the corresponding fuel benefit and receive a certificate linking their allocation back to the original fuel certificate.<\/p>\n<p>On the other hand, the diesel project would record information at each stage of production, transportation and use, joining those records into a history of the fuel\u2019s journey.<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"http:\/\/sitedemo.beget.tech\/559\/wp-content\/uploads\/2026\/10\/ecc3c5765c6b7be16d749364d51b5aff.webp\"  \/><\/p>\n<p> The fuel goes one way, the green credit goes another. (Shaurya Malwa\/CoinDesk)  <\/p>\n<p>That could help companies report Scope 3 emissions, the indirect emissions across their suppliers and customers, where the information needed often sits with other businesses.<\/p>\n<p>Both projects remain research work. The diesel model is described as proposed, and the announcement disclosed neither fuel volumes covered nor a timeline for wider use.<\/p>\n<p>Cardano also joined x402 this month, a payment standard that lets apps and AI agents pay for data or computing services as they request them. Its initial payment-processing software had been tested on Cardano\u2019s pre-production network, with commercial use on the live blockchain still to be demonstrated.<\/p>\n<p>               <span class=\"show-xs\">     <\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"http:\/\/sitedemo.beget.tech\/559\/wp-content\/uploads\/2026\/10\/66728def105d4c79590a3f28d73bc74a.jpg\"  \/><\/p>\n<h2>Know when your<br \/>coins move<\/h2>\n<p>Alerts, real-time prices, and market news \u2014 all in one app              <\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"http:\/\/sitedemo.beget.tech\/559\/wp-content\/uploads\/2026\/10\/daea2462cd06e05f874e1deb5ba0ed6b.jpg\"  \/><\/p>\n<p>         <span>4.8 based on 40K reviews in the App Store and Google Play<\/span>                                <\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"http:\/\/sitedemo.beget.tech\/559\/wp-content\/uploads\/2026\/10\/61524fb4c25ba9f47833030c5e38c608.jpg\"  \/><\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"http:\/\/sitedemo.beget.tech\/559\/wp-content\/uploads\/2026\/10\/1a9a4f5be1fccf793d4fd0a86ff11d67.jpg\"  \/><\/p>\n<p>               <\/span><\/p>\n<p><a target=\"_blank\" rel=\"nofollow noopener\" href=\"http:\/\/cryptonews.net\/news\/altcoins\/33519353\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Petrobras, Brazil\u2019s state-controlled energy company, is testing the Cardano blockchain to track claims about lower-carbon fuel, in two research projects announced Wednesday by the Cardano Foundation shared with CoinDesk.
