While this is true, if you were to calculate the last-mile carbon cost it would be much, much higher. A full container of goods costs about 60 gallons of diesel to ship across the world. That same container costs 60 gallons to move 360 miles from a port. Delivery vehicles drive approximately 0.8 miles per package delivered, and get around 10-20mpg delivering, so each package costs 1/10 to 1/20 of a gallon of fuel to deliver from the depot to your door. Assuming there are 4000 eventual packages in a container, the last mile delivery for the container is 200-400 gallons. Obviously this is not the case where the final destination is a large receiver, but even then there are still significant transportation impacts in most cases. I hate the fact that when I read the part about sulfur dioxide I’m like, well, that’s good at least lol. There’s some evidence that cleaning up ship emissions might be a significant contributor to recent sea temperature acceleration, since the cloud seeding effect from ocean shipping has been drastically reduced.
