so the only solution in that post is to go slower to reduce emissions so with that technology as a path to zero emissions means the ship wont leave the dock.
Low sulphur fuel and scrubbers have reduced pollution as for anything else its seems to be just headlines on reduced carbon but almost nothing on how that will be achieved.
I stand by my statement that the industry has done almost nothing compared with just about every other polluting industry in all the years and just likes talking about reduced emissions.
