Not really. Many of the auto pollution controls are in use because they were mandated by CARB. California is a big enough market that it made sense to make cars that made less pollution, which brought down the cost of the pollution-control bits, which made them easier to mandate on a federal level, which then made them appear all over the country.
The US is still the largest consumer of the stuff that comes off those ships. If the ships are required to clean up their act to enter US waters, they still end up cleaner wherever they sail.
