There is no mention of the amount of fuel used to transport the fuel in the article. From what I know it’s a tiny fraction: boats are efficient at transporting stuff (slowly)
> Fossil fuels are roughly 40% of maritime tonnage, but in the model they represent about half of maritime freight energy because coal, oil, and gas are mostly long-haul bulk trades. Moving a ton of scrap metal a short distance and moving a ton of oil or LNG across oceans are not the same transport-energy problem, even if both show up as one ton in a cargo table.
as being exactly what was being talked about... more fuel is spent on transporting fuel due to distance it travels.
but your comment made me re-visit (i.e. more closely skim...) the article, and it's really about: "as the demand for fossil fuels is projected to decrease, (1) less long-haul shipping is needed and (2) a greater fraction of shipping will be short-haul, which will be practical for other types of freight fueling (i.e. what's shown in the figure at the top of the article)
I have no sense of how realistic the figure is. For example, I don't know the current projections for decline of fossil fuel demand over ?? year timeframe.

I kind of read this
