Doesn't much of these sulfur emissions disperse and break down before it reaches land when they're out to sea? There's already a lot of activity to reduce emissions when ships are near land. In Norway there's a big push to provide electricity from land when the ships are docked. There are also a very big hybrid ferry that has enough battery to run electric for the first and last few minutes near land. Maersk wants to have its first carbon neutral vessel by 2023, and be net zero emission by 2050. That's probably going to be done with ammonia as fuel, which I don't think has big problems with emissions. So it seems like there's already a good amount of pressure to solve this problem. Could be better of course. But "the largest emissors don't change one bit" is pretty far from true. Shipping is not really the biggest problem in total emissions, especially for CO2, and seems to be following the development in the zero emission space quite well.
