Look up North American ECA - anywhere within 200 nautical miles of the coast they either have to be fitted with exhaust gas scrubbers or burn LSD (Low Sulphur Diesel)

It used to be 12 mile limit for whole world? Example military. When has this changed?
And so I have a large commercial ship. With a flick of a switch I can change from the clean expensive tank of fuel to the dirty cheap tanks of fuel. How can they catch me? Haha you think Liberia or whatever flag of convenience I'm registered with for home base is going to somehow care or try to monitor me?
Plus everything is in international waters so nobody has jurisdiction.
