6.3 Transportation modes
6.3.1 Truck transport
A European semi-trailer truck has a total weight of 40 t. The empty weight is 14 t,
and the payload capacity is 26 t. The bigger the truck is, the higher the ratio of payload
and empty capacity is. 40 t trucks carrying goods between two distribution centres have
a lower emission per t km than a small truck for the distribution within a city as shown
in Table 6.6.

For the calculation of the emission of truck routes, the actual measured data as
well as the calculation of diesel consumption for a specific route can be used. In terms of
calculation, Table 6.7 gives different values for the energy consumption depending on
truck size, route and kind of cargo.
