After having been adopted by the International Maritime Organization (IMO) in 2008, tighter limits on the sulphur content of shipping fuel finally came into force on 1 January 2020. From this date the maximum permitted sulphur content was lowered from 3.5 to 0.50 per cent, resulting in an estimated three-quarter drop in the emissions of harmful sulphur dioxide (SO₂), linked to acid rain and a range of pulmonary and cardiovascular diseases.
The transition to the new sulphur regulation has so far happened without major problems, the IMO reported in late January. The next step is a carriage ban on non-compliant fuel oil (except for ships with exhaust gas cleaning systems installed) that enters into force on 1 March 2020, helping to support implementation of the global sulphur limit.
