Germanischer Lloyd unveils CO2-index

Germanischer Lloyd has launched a prototype CO2-index, based on MEPC/Circ.471.

The index is available for all GL classed ships. Each ship owner and management company can check the complete survey status of their GL-classed fleet. The CO2 emission will be measured on the basis of installed power, consumed fuel and transported cargo. Computed index values can be compared to other ships' indices and eventually be used to minimize emissions from transport. The CO2-index tool by GL can be used to record fuel consumption, transported cargo and distance between two consecutive ports. With carbon emission factors specified by IMO, the CO2-index is calculated for each voyage and later averaged for a still to be defined period (a year might be practical). At the end of the period, a GL surveyor will check the recorded data and eventually issues a certified CO2-index on behalf of a flag state, which is then valid for the next period. If data for more than one vessel is entered into the online tool a comparison of CO2-indices across a fleet is possible. With certified CO2-index values becoming public, the transport industry can actively further minimize emissions. Ships with a low index will transport more cargo and improve their index even further.
