Influence of the required EEDI reduction factor application on general cargo ships GHG emissions

In order to improve energy efficiency for ships and to reduce their Greenhouse Gas (GHG) emission the Energy Efficiency Design Index (EEDI) was introduced. For every new ship the attained EEDI has to be calculated and not higher than the required EEDI, which is determined by the reference line value and the reduction factor defined in a set of time intervals. The aim of this paper is to analyze how the application of the required EEDI reduction factor will influence the general cargo ships GHG emission in future. These ships average lifetime is much higher compared to other ship types. Since the EEDI applies only to new ships it is interesting to analyze the effect of the EEDI implementation on their GHG emission in future and to compare it with the requirement of reaching mean global CO2 stabilization level in the atmosphere. The analysis showed that in order to reach the stabilization level a more stringent policy is required for general cargo ships which would encourage the implementation of innovative energy efficient technologies and result in lower GHG emission.
