Example 6:
A 24 t truck transports 3 t of fashion goods from Berlin to Dresden. The distance
is 250 km. The route is mainly flat. Fashion goods are volume goods. So the total diesel
consumption is
F
= 3 t x 250 km x 0.033 l/t km = 24.75 l.
6.3.2 Train transport
Train transportation can take place with diesel engines or the train can use
electrical energy. As for the truck, the higher the total weight of the train is and thus the
weight of the transported good, the lower the specific energy consumption is per t km
for the transported good. If electricity is used, the CO
2
emission depends on the energy
mix for the energy production (see Table 6.8).

Example 7:
A train runs from Barcelona to Hamburg. The distance is 1,800 km. Heavy
machine parts are sent in a 2 TEU container. The total route is electrified. The total
weight of the train is 2,000 t. The energy consumption is:
F
= 2 TEU x 1,800 km x 0.307 kWh/t km = 1,105.2 kWh.
6.3.3 Sea transport
For the sea transport different kinds of vessels exists. The most important are:
• General cargo vessels.
• Dry bulk carriers.
• Liquid bulk carriers.
• Container carriers.
• Roll-on-roll-off vessels.
