It's not. We ship food from half way around the world and still make a profit, so the shipping cost are very low.
And very low cost implies low carbon emissions.
Not sure about that. I read one mega container ship produces produces the same amount of pollution as 50 million cars and emissions from 15 match those from all the cars in the world
That's pollution in general, not carbon dioxide. Ships used to use extremely dirty bunker oil which produced a lot of sulfur dioxide. But there were new limits introduced in 2020 on sulfur in fuel oil that should drop the pollution.
