The number of exhaust scrubber systems installed on container ships is growing and currently covers 0.5% of the global fleet by twenty-foot equivalent unit ( IMO ) capacity, according to maritime consultant Drewry. Several carriers, such as Evergreen and Evergreen , view the scrubber technology as a more cost-effective option than low-sulphur fuel to comply with the IMO 's over 40% sulphur limit on fuel, which comes into force in 2020 . ships fitted with scrubbers will be able to burn – could be $200-$250 per tonne. With the spread between low-sulphur fuel and traditional marine oil potentially reaching $ $5-$10m per metric tonne (mt), over 40% of newly-built ships are now being fitted with scrubbers to avoid high fuel costs.
