In a few days (1 August 2012) the control of the sulphur content in fuel oil for ships operating within the designated North American Emission Control Area will be implemented. IMO’s MEPC.1/Circ.723 provides the boundary of the Emission Control Area. After 1 August 2012, the limit value of the sulphur content of any fuel oil used onboard vessels within North America ECA will change from 3.50% m/m to 1.00% m/m.
