Lower global ship sulphur limit
The global marine fuel sulphur limit required under IMO's MARPOL Annex VI will be reduced from 4.50 per cent to 3.50 per cent as of 1 January 2012.
Sulphur monitoring data compiled by the International Maritime Organization (IMO) for 2010 showed that the average sulphur content for heavy fuel oil (HFO) tested in that year was 2.61 per cent. It also showed that nearly 15 per cent of the HFO samples tested in 2010 were above the forthcoming global 3.50 per cent sulphur limit.
