Newcastle receives it's fair share of coal pollution, but all coal ships etc are brought in via tugboats. I don't believe they are at anywhere near full steam until a little way out to sea. So they do some care, but probably not enough.
However, they do use poorer quality fuels and belch huge amounts of smoke. Terrible. Great read. Thanks.
"Confidential data from maritime industry insiders based on engine size and the quality of fuel typically used by ships and cars shows that just 15 of the world's biggest ships may now emit as much pollution as all the world's 760m cars. Low-grade ship bunker fuel (or fuel oil) has up to 2,000 times the sulphur content of diesel fuel used in US and European automobiles."
