| Abstract: | In addition to fuels, passenger and freight transport require vehicles and infrastructure. As with fuels, the provision of goods and services that are needed for the operation of transport involves the consumption of energy and the emission of greenhouse gases. The energy consumed and greenhouse gases emitted due to fuel use by vehicles are referred to as direct requirements, while indirect requirements of energy and greenhouse gases are embodied in the goods and services mentioned before. Indirect requirements form a significant part of the total energy and greenhouse gases required for a given transport task. They depend on the transport mode, ranging from 10% to 50% for freight transport and from 25% to 65% for passenger transport. These indirect requirements have to be taken into account when options for reducing the energy consumption and greenhouse gas emissions of the transport sector are to be evaluated. |
