Emissions for ships does not apply in international waters for most of the planet, so they tend to be clean(ish) in territorial waters, then switch over to any old cheap crap when outside.
When I was at GE delivering vessel control and propulsion systems, it was quite an eye opener as to the lengths the vessel designers went to to make this all happen, extra tanks, extra pumps, fuel heaters, different engine/governor/avr mappings etc etc.
They have at least introduced ballast water cleaning systems to try to stop the carrying of invasive species around the planet (some of which were even massive power consuming microwave setups)
