Key policy question: Are the various passenger and freight transport modes becoming more energy efficient?

Key messages

  • Specific CO2 emissions of road transport have decreased since 1995, mainly due to an improvement in the fuel efficiency of passenger car transport. Recent EU Regulation setting emission performance standards for new passenger cars is expected to further reduce CO2 emissions from light-duty vehicles in view of the 130 g/km and 95 g/km emission targets set for 2015 and 2020 respectively.
  • Specific CO2 emissions of air transport, although decreasing, are of the same order of magnitude as for road, while rail and maritime shipping remain the most energy efficient modes of passenger transport.
  • Specific energy efficiency of light and heavy duty trucks has improved, but road transport still consumes significantly more energy per tonne-km than rail or ship freight transport.

Note: The graph shows development of specific CO2 emissions for the road transport mode, by category (passenger cars, vans, two wheelers, buses & coaches, light-duty vehicles, heavy-duty vehicles) in 1995 and 2009.

Key assessment

The specific CO2 emissions of the road sector were reduced between 1995 and 2009 by 10 % for passenger transport and 14 % for freight transport. The energy efficiency and CO2 per passenger-kilometre of passenger car transport has improved by almost 11 % over the same period and this improvement results partly from the voluntary agreement of the automotive manufacturing industries. The reductions in road freight transport are due to both technical improvements of the light and heavy-duty trucks (mainly in the engine efficiency) and increased activity of the heavy-duty trucks, i.e. higher load factors.

The combined effect of improvements in aircraft technology and increased load factors has resulted in a decrease in specific CO2 emissions of air passenger transport by 29 % between 1995 and 2009. But because transport volumes have grown faster than efficiency improvements the total emissions are still growing.

Rail is the second most energy efficient mode of both passenger and freight transport (after maritime). Specific CO2 emissions of rail transport have decreased by about 27 % from 1995 to 2009 for passenger transport, mainly due to shifting from diesel to electric trains. For freight transport the decrease over the same period was 14 % as a result of both technological improvements and increased load factors. The CO2 emission factors for electricity production represent the emissions incurred during the whole production and supply process from fuel extraction to electricity transport to the sub-stations feeding the railway network.

The energy efficiency of maritime shipping has only recorded slight changes of the order of almost 4 % in the time period considered.

Specific assessment

CO2 emissions from the new passenger car fleet in the EU‑27 decreased from 140.2 g CO2/km in 2010 to 135.7 g CO2/km in 2011. The overall trend is one where average emissions of CO2 have decreased steadily since 2000. If similar progress is made each year, then the 2020 target for passenger cars for achieving a fleet average of 95 g CO2/km will also be achieved. However, there is also discussion regarding the real fuel consumption of vehicles, and therefore CO2 emissions (see Section 4.3)

Data to monitor the average emissions of CO2 for the new van fleet are not yet available. Member States will be required to monitor and deliver this data from 2012. However, it has been estimated that average CO2 emissions for the new van fleet decreased from 203 g CO2/km in 2007 to 181 g CO2/km in 2010.
