Environmental impact of shipping engines can be higher on a port-specific basis. Ultra-low sulfur diesel (ULSD) is a standard for defining diesel fuel with substantially lowered sulfur contents.

In 2016 the IMO has made new sulfur regulations which must be implemented by larger ships by 2020. Of total global air emissions, shipping accounts for 18 to 30 percent of the nitrogen oxide and 9 percent of the sulphur oxides. Sulfur in the air creates acid rain which damages crops and buildings. When inhaled,
The Sulphur Institute addresses environmental and safety issues surrounding the transportation, production, and storage of sulfur. The Sulphur Institute's program allows regulatory agencies and industry stakeholders to connect, exchange knowledge, and develop practices which improve the safety of the industry. The Sulphur Institute provides members, government and non-government agencies, and industry stakeholders accurate information on sulfur. TSI has served as a source of industry information for many publications including the Wall Street Journal. TSI is often quoted by publications within the industry as well. The information gathered by TSI is made available through a number of publications, webinars, and speaking engagements. The Sulphur
