In total, 13 specific measures for reducing CO2 emissions have been analysed for two selected case ships to illustrate the methodology. Results from this work shows that several measures are cost effective according to the proposed criterion. The results suggest that cost effective reductions for the fleet may well be in the order of 30% for technical measures, and above 50% when including speed reductions. The results of this study show that the cost effectivenessapproach for the regulation of shipping emissions is viable and should be pursued in the ongoing regulatory process
