Summary
Functional unit: 
One tonne cargo transported one km
Goal and scope of the summary: 
Interest in new fuels for marine propulsion is growing, mainly as a result of environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Different fuels and technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment. In order to measure the environmental performance of maritime fuels, this study analyzes the life cycle of four fuel types: heavy fuel oil, marine gas oil, liquefied natural gas and Fisher-Tropsch diesel produced from natural gas combined with two abatement technologies. The geographical location is set to the North Sea and the Baltic Sea and the time perspective is 2015 to 2020. The studied system includes extraction of raw materials, production and transportation, bunkering, storage and finally combustion of fuels for the transportation of one tonne cargo 1 kilometre. The study will thus include all activities from raw material extraction to the release of waste to the environment.

I was unaware of this and

I was unaware of this and also never thought about the life cycle of marine fuels. Anyways by reading your post my knowledge has been updated.
