Indicator: Energy consumption in transport

A graph shows final energy consumption in the transport sector between 1991 and 2017 as well as the Federal Government targets. Consumption in freight and passenger transport are shown (2005 = 100).Click to enlarge

At a glance

  • The Federal Government wants to lower final energy consumption in the freight and passenger sector by 15 to 20 % by 2030 compared to 2005.
  • However, final energy consumption in transport seems to stagnate at a high level with an upward trend in recent years. It will be difficult to reach the target.
  • Since the early nineties, freights and passenger transport have become significantly more efficient.
 

Environmental importance

Transport requires energy. Making energy available, distributing and using it are causing multiple problems in a global context.

The predominant source of energy in the transport sector is oil, which is often extracted in or transported through ecologically sensitive areas. Further energy input is needed in refining the crude oil into petrol, diesel or aviation fuel, and finally, the combustion of fuels releases pollutants such as nitrogen oxides and particulate matter. The main focus, however, is on the greenhouse gases that arise from combustion and that are responsible for the global climate change.

For all these reasons, the Federal Government decided to reduce overall energy consumption – including the energy consumption of the transport sector.

 

Assessing the development

In the long term, the development of final energy consumption in transport does not show a clear direction: until 1999, consumption initially increased, then decreased and has been increasing again since 2010. From 2005 to 2017, the final energy consumption of passenger transport rose by around 2 %. In freight transport, on the other hand, it rose by around 7 % over the same period. Nevertheless, over the same time frame, transport performance rose faster than its energy consumption. As a result, both transport sectors have become significantly more energy-efficient.

In its Energy Concept the German Federal Government set an energy-saving target for the transport sector in 2010. By 2020, final energy consumption should be 10 % below 2005 levels, and 40 % below by 2050 (BMWi, BMU 2010, in German only). In its revised Sustainable Development Strategy of 2016, the Federal Government has defined an intermediate target for 2030 (BReg 2016). By then, energy consumption in the passenger as well as in the freight transport sector should fall by 15 to 20 %. This makes it hard to reach the 2020 reduction target.

If energy consumption in the transport sector is to fall, more energy-efficient alternatives must receive more support (cf. ‘Environmentally friendly passenger transport’ and ‘Environmentally friendly freight transport’).

 

Methodology

Energy consumption in the transport sector is calculated using the tool TREMOD (Transport Emission Model), based on transport volume and specific energy consumption. TREMOD was developed by the ifeu - Institute for Energy and Environmental Research in Heidelberg, commissioned by the German Environment Agency. Methodological backgrounds are explained here.

The Federal Government determines energy consumption of the transport sector as part of its energy transition monitoring, using data provided by the Working Group on Energy Balances (AGEB) as a baseline. These, in turn, are based on fuel consumption. The data used for our indicator on the basis of TREMOD are different from those used by AGEB.
