An ambitious target, this presents an opportunity and need for acknowledging the lifetime impact of marine fuels for meaningful comparisons between alternative fuels. This study attempts to produce such an assessment in the context of naval marine fuel oil from well-to-tank. It focusses on the impact of receiving crude oil from different nation states and considers the lifecycle impact of that fuel based on the nature of its extraction and transport. Through this process the well-to-tank lifecycle equivalent greenhouse gas emissions index of Diesel Fuel Naval Distillate to F-76 specification is calculated to be 12.2 gCO2e/MJ. The vast majority of this number is produced by the extraction phase of the fuel, whose data is spurious at best. The large reliant of accurate data from nation states makes this a difficult process to undertake with integrity. Nations and oil extraction organisations are incentivised to under-estimate or obfuscate their environmental impact of extraction, leading to Green House Gas (GHG) indices whose accuracy is questionable. The reliability of the index is reliant on the measures of transparency present in the nations from which the data is taken.}, doi = {https://doi.org/10.24868/10684}, recid = {10684}, address = {2022-09-23}, }
