Many studies have shown that the fuel efficiency of ships can be improved considerably at a net profit. This report identifies the main barriers for uptake of cost-effective measures and presents a comparative analysis of different marginal abatement cost curves (MACCs).
It transpires that the differences in the available MACCs can be largely explained by use of different emission baselines and slightly varying sets of measures. Other contributing factors are minor differences in the costs and estimated potentials of specific measures and differences in the projected fleet structure.
The report identifies three main reasons why not all cost-effective measures are currently being taken:
