Kind of. I’m wondering what percentage of that total figure is comprised of US shipping, as that could get somewhat fuzzy. Would that include all goods coming to or from the US, regardless of the flag or import company’s national origin, etc? BL, just curious about how that percentage was derived.
I dug this out of some notes for a class I once taught...
"Ocean shipping is the most energy efficient forms of freight transportation. Recent estimates show that moving goods by ocean container can be 17 times more fuel-efficient than transporting the same goods by air, and 10 times more efficient than transporting goods by road."
BUT...
"a large modern container vessel used in Trans-Pacific trade, with a maximum container capacity of 7,750 TEUs (twenty foot equivalents) or 3,875 FEUs (forty foot equivalents) using a cost of bunker fuel at $552 per ton, and with
fuel consumption of 217 tons per day, a single 28-day round trip voyage for this one vessel would produce a fuel bill of $3,353,952.
THERE'S MORE...
"Just one of the world’s larger container ships can emit about as much pollution as 50 million cars. Further, the 15 largest ships in the world emit as much nitrogen oxide and sulphur oxide as the world’s 760 million cars."
All of this was a draw to a discussion on the history of non-military nuclear powered ships.
