The focus of this work is to map the value and production chains of Aviation Kerosene Fuel (AKF), with particular attention to the points where decarbonization actions are being implemented and monitored. To do so, we propose the use of blockchain technology, which allows the creation of an immutable record of production and value chains for this fuel. This approach provides transparency throughout the process – from production to fueling aircraft – by ensuring the traceability of AKF s origin and its compliance with safety regulations. As a major contribution, the study proposes the tokenization of attributes related to decarbonization through NFTs (Non-Fungible Tokens), that could serve as evidence tools for end customers and even be traded in a secondary market. The decentralized and immutable nature of a Distributed Ledger Technology (DLT) not only enhances the management of metrics associated with the energy transition but also minimizes the risk of fraud, enabling the automation of transactions through smart contracts.
