    HighlightsWe compared the life-cycle emissions of HFO and LNG as fuels for two ships operating between Mainland China and Taiwan.Both ships emit much less NOx and SO2 but much more CO and PM when LNG is used to power ships.For cross-Strait shipping a substantial reduction in SOx and PM level can be achieved.

    AbstractWe conducted a total fuel life-cycle inventory for atmospheric emissions for two ships operating between Mainland China and Taiwan, comparing the difference that may result from operating on heavy fuel oil (HFO) and on liquefied natural gas (LNG) as fuels. In addition, we assess the global warming impact from these two fueling alternatives. We use a commercially available life-cycle assessment (LCA) software to conduct a life-cycle inventory of airborne emissions from the ship fuel use. Our findings indicate possible improvement in total fuel-life-cycle GHG emissions from the use of LNG as alternative fuel to power ships. While total GHG and CO2 emission reduced, however, methane emissions increased significantly when LNG is used as alternative fuel to power both of our case ships. Both ships exhibit great reduction in the emissions of NOx (38–39%) and CO (42–43%). The reduction is much more remarkable in SO2 (99.8%) and PM10 (97.5%). The weight of emissions from operation stage has become relatively smaller in the whole fuel life-cycle total GHG emissions, when the two ships move to operate on LNG.
