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. Table 6.6 Payload and weight for different truck sizes Empty weight (t) Payload capacity (t) Total weight (t) Payload/empty capacity 4 3.5 7.5 88% 6 6 12 100% 9 17 26 189% 14 26 40 186% 19 41 60 216% 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.
