Abstract
This study quantified Well-to-Wake (WtW) GHG emissions from ship energy sources during in-port operations, in accordance with the IMO 2024 LCA Guidelines. Using 3-year field measurements from a training ship, daily WtW emissions were 4,673.4 kgCO2eq for Bunker-A and 4,642.7 kgCO2eq for Diesel Oil. Shore power achieved a 73.4% reduction in CO2eq emissions (1,243 kgCO2eq/day) compared with Bunker-A, validating its effectiveness for maritime de-carbonization. Analysis of the 1 kg emission intensity revealed that the emission intensity of Diesel Oil (4.005 kgCO2eq) was higher than that of Bunker-A (3.969 kgCO2eq) because of its superior energy density. These results establish a quantitative baseline for a GHG Fuel Intensity (GFI) framework and emphasize the necessity of integrating renewable energy into port grids.
