Analysis of estimated index values of ships that have entered the fleet since 2009

Sketch of a book (default image for publications

There is little publicly available information on how the design efficiency of ships that have entered the fleet since 2009 has developed. The IMO has published the energy efficiency design index (EEDI) of a limited number of ships launched since 2012, but the sample of ships is small and the time period limited. The published data show clearly, however, that estimated index values (EIV) and EEDIs of ships are well correlated.

Study of historical trends in ship design efficiency

This first-time study of the historical development of the efficiency of new ships shows that, in fact, the efficiency of new ships has actually deteriorated since 1990 by 10% on average. This demonstrates the failure of market forces to reduce ship and shipping emissions and emphasizes the need for regulation.

Monitoring of bunker fuel consumption

Monitoring of fuel consumption and GHG emissions from international shipping is currently under discussion at the EU level as well as at the IMO. There are several approaches to monitoring, each with different characteristics. Important differences exist with regards to the costs of the equipment, operational costs, the accuracy of the measurements, and the potential to monitor emissions of gases other than CO2. Moreover, some approaches offer more opportunities to improve the operational fuel-efficiency of ships and fit better to possible future policies than others.The following report discusses these approaches.

Regulated Slow Steaming in Maritime Transport: An Assessment of Options, Costs and Benefits

This report studies the impacts of vessel speed on emissions, technical constraints and other experiences with regard to slow steaming and current speed regulations. Moreover, it analyses the legal feasibility of speed limits and feasibility of implementation, possible policy designs and the associated social costs and benefits of speed limits.
