Blockchain-based system for carbon accounting in intermodal transportation

Supply chain logistics significantly contribute to global CO 2 emissions, with transportation as the largest source of emissions. Carbon accounting plays a critical role in monitoring, measuring, and reporting emissions across supply chains, helping to identify key carbon-intensive areas. This is important in intermodal transportation, where switching between different transportation modes optimizes efficiency and cost but complicates emissions tracking and accountability of emissions. Current methods lack transparency, hindering effective monitoring. Blockchain offers a decentralized solution, enabling secure and transparent carbon accounting. This paper proposes a blockchain-based system for carbon accounting in intermodal transportation emissions using Ethereum smart contracts.
