At the end of October, an IMO meeting in London will decide whether to cap the sulphur content of shipping fuels by 2020 or 2025.
And although new global rules for shipping to cut sulphur pollution are due to come into force in 2020, the sulphur content of shipping fuel will still be 500 times more than road diesel.

The accept residue or FS10 was then air-dried to moisture content of 15% and shipped to the USDA Forest Products Laboratory, Madison, WI.
