What Annex VI does is it limits the amount of sulphur content in all ships' fuel to half a percent. It requires certain diesel engines to comply with certain emission standards. It requires certain ship board incinerators to meet performance standards. It is about banning the incineration of certain substances. It is also about ensuring that ships with a mass of 400 gigatonnes or more meet energy-efficiency requirements. So there is a lot going on here on the ship, but also ensuring that the port facilities are capable of dealing with the residues and the waste that these ships need to come off.
