Methodology and use of EEOI, as described in these Guidelines,
provide an example of a transparent and recognized approach for assessment
of the GHG efficiency of a ship with respect to CO2 emissions.
The Guidelines are considered to be suitable for implementation within
a company environmental management system.
Implementation of the EEOI in an established environmental management
system should be performed in line with the implementation of any
other chosen indicator and follow the main elements of the recognized
standards (planning, implementation and operation, checking and corrective
action, management review).
When using the EEOI as a performance
indicator, the indicator could provide a basis for consideration of
both current performance and trends over time.
One approach
could be to set internal performance criteria and targets based on
the EEOI data.
