Air Emissions

Air emissions from ocean going vessels are regulated by the International Maritime Organization through the work of the Marine Environmental Protection Committee (MEPC).


Important progress has been achieved over the past decade in regulating marine air emissions through the efforts of signatories to the IMO’s International Convention for the Prevention of Pollution from Ships (MARPOL).

From January 1 2015, under the North American Emissions Control Area, the allowable sulphur content in marine fuel oil was reduced to 0.1% for all vessels transiting within 200 nautical miles of Canada and the US .

While representing an important and sustained investment in coastal air quality, the North American ECA and other regional ECAs represent a significant increase in fuel costs to the marine industry.
