According to the International Maritime Organization (IMO), emissions of sulphur oxides (SOx) are known to be harmful to human health and they contribute to ocean acidification. IMO regulations to reduce sulphur oxides (SOx) emissions from ships first came into force in 2005, under Annex VI of the International Convention for the Prevention of Pollution from Ships (known as the MARPOL Convention). Since then, the limits on sulphur oxides have been progressively tightened.
From 1 January 2020, the limit for sulphur in fuel oil used on board ships operating outside designated emission control areas will be reduced to 0.50% m/m (mass by mass). This will significantly reduce the amount of sulphur oxides emanating from ships and would have major health and environmental benefits for the world, particularly for populations living close to ports and coasts.
