The modelling of emission factors is based on technical data of 4616 sample vessels. Technical
data was collected from Lloyds Register of Shipping /Lloyds 2009/. The validity of the
sample was tested by comparing the findings with the aggregate results for CO 2 emissions
in the updated greenhouse gas study by the IMO /Buhaug et al. 2008, IMO 2009/.
Emission factors are developed for each individual vessel (EFv). The principle derivation of
emission factors uses main and auxiliary engine data, capacity data and activity data. Emission
factors for container vessels have been derived in g/TEU-km (TEU = twenty foot
equivalent unit = standard container of 20’ length), whereas for all others vessels the factors
are based on g/tonne-km. The EFv are based first on nominal carrying capacity with the subsequent
inclusion of vessel utilization and empty trips.
EFv = engine data x vessel capacity data x vessel activity data x vessel utilization factor
The final emission factors for the different vessel types, size classes and trade lanes are
then weighted averages of the vessels’ individual emission factors. In the expert modus,
specific vessel types and size classes can be selected. In the default modus of EcoTransIT
