Climate Impact of Nitrous Oxide (N2O) from Ammonia Based Shipping Fuel (Well-to-Wake)

This tool quantifies well-to-wake reactive nitrogen (Nr) emissions from the ammonia fuel value chain, drawing on industry insights and research literature about ammonia as an emerging marine fuel. Users are advised to run the default model inputs before making adjustments (see User Manual). The results and discussion of parameterized scenarios are detailed in the submitted journal article titled 'The climate impact of direct and indirect N2O emissions from the ammonia marine fuel value chain' by Esquivel-Elizondo et al. (2025).
