Shipping via sea is the cheapest and least greenhouse gas producing way to ship things.
AFAIK all ships still run on fuel. Esecially the huge ones.
While a lot of emmissions are “hidden” in the infrastructure, ships still have infrastructure: the ports and terminals weren’t always there like the sea. Less infrastructures than other modes to be sure, but certainly not “free”.
Well there’s a clear thing you need to do now: go figure out the proportion of greenhouse gasses for a given shipped item caused by shipping. Someone has done the research, seems like you ought to find it.
