There have been a number of estimates of the magnitude of the cost to the shipping community of implementing the global 0.50% sulphur cap in 2020.
Recently, Wood Mackenzie grabbed the headlines by saying global bunker fuel costs could rise by up $60 billion annually from 2020, in a full compliance scenario, when the International Maritime Organization (IMO) regulation kicks in.
