A mere two months before the IMO‘s new Carbon Intensity Indicator (CII) regulations for the maritime industry come into force, shipping lines have started to raise concerns about the rating scheme’s impact on global transport and IMO’s approach to calculating CII.
MSC, Maersk and Hapag-Lloyd have claimed the rules were “not sensible” or even counterproductive. MSC stated that enforcing the CII could reduce effective container vessel capacity by up to 10% if less efficient ships reduce sailings speed to remain compliant.
The question whether these concerns are justified or possibly overblown is not easy to answer. Some of the recent criticism is valid, but side effects of the CII introduction will depend upon each carrier’s fleet, vessel size and age, sailing speeds, and routes served.
