it's not perfect but it's gotten better apparently. 170 countries have signed a treaty significantly reducing the fuel sulphur content.

  The upper limit of the sulphur content of ships' fuel oil was reduced to 0.5% (from 3.5% previously) - under the so-called "IMO 2020" regulation prescribed in the MARPOL Convention. This significantly reduces the amount of sulphur oxide emanating from ships.

Ironically, a reduction in sulfur emitted from these ships may actually accelerate global warming: https://www.technologyreview.com/2018/01/22/67402/were-about...
