I don’t have data handy but I know that ships use a lot more diesel fuel and it’s always been a lot dirtier than trucks (look up bunker fuel)
True, I knew bunker fuel was worse, but I hadn’t looked up just how much worse.
I do remember that similar effects have happened with cleaning up particulate emissions from coal plants and industrial facilities.
