Why are there no fuel options for some of the truck sizes in Final Footprints?

Options available are due to available factors, in this case the Global Logistics Emissions Council database. There are no specific fuel factors available for heavy and medium goods vehicles, and for luton and panel vans, the available options are those that exist in the GLEC database. There is no HVO or electric/hybrid based factor at present but we understand they are expanding the fuel source lists - as they become available, the tool will be updated. Note that for North American trucking (i.e. journeys in the US and Canada), there is no fuel granularity in the factors at all, so picking one over another will not change the resulting co2e, but the options have been kept for data analysis.
