Container ships versus trucks and trains

This data-file tabulates c10 examples for the fuel economy of container vessels, which is a function of their size and speed.

The most efficient container ships are 2x more efficient than typical trains and 20x more efficient than typical trucks.

We calculate that moving goods from overseas to the developed world’s c1bn consumers accounts for c0.5% of global CO2 emissions (c50% in ships, c50% in trucks). These calculations are also shown in the data-file.
