> I thought the maritime industry didn't care one bit about the environment and would use nasty fuel once in international waters? As of 2020 the sulphur limit has been lowered from the previous 3.5% to 0.5% (which is still a lot higher than modern road diesel). Alternatively, ships can use scrubbers to remove sulphur oxides from the exhaust gas. http://www.imo.org/en/mediacentre/hottopics/pages/sulphur-2020.aspx http://www.imo.org/en/mediacentre/hottopics/pages/sulphur-20...
