The Royal Belgian Shipowners Association (RBSA) commissioned the University College of London (UCL) Energy Institute to investigate into the CO2 emissions. In addition this, the association has also asked the university to look into the Energy Efficiency Operational Indicator (EEOI) and the recent changes in the policies such as EU MRV policy, by studying each ship’s and fleets’ data of the past five to six years.
The data gave the association a credible opinion about the advantages of the several indices measuring the energy efficiency indices. This will help the members of the association to predict the changes that the energy industry needs to make. The report explains the various challenges policymakers face while implementing MRV due to the unsure data and the haphazard ways of rectifying it.
IMO developed the Energy Efficiency Operational Indicator (EEOI) to permit vessels to track their carbon emissions. This indicator sums up the entire carbon emissions in a given time frame per unit of revenue ton-miles. The variations seen in the index are due to the amount of cargo transported per unit of time, technical efficiency of the ship, and changes in speed. However, due to the aggregation that EEOI provides it is extremely difficult to gauge the influence of these variables. Along with calculating the values of EEOI and carbon emissions in the RBSA’s owner’s fleets, this study was aimed at breaking down EEOI into sub-indices that would measure the contribution of the ballast, laden, ballast and port segments for 94 ships.
