Energy efficiency index for transport

  • Energy efficiency improvement of 0.6%/year between 2000 and 2019, as measured by ODEX that combines the energy efficiency trends of the different modes of transport (cars, trucks and light vehicles, bus, motorcycles, air, waterways, rail).
  • Energy efficiency progress for cars was slower (0.4%/year), and quite low since 2014, because of an increase in the specific consumption of new cars, due to two main factors: a decrease in diesel shares (from 56% in 2012 to 34% in 2019) and a growing share of SUV (from 25% to around 40%).
  • After a slowdown for trucks and light vehicles since 2005, with no more efficiency progress between 2008 and 2012 because of the economic crisis, energy efficiency is improving again (0.7%/year on average since 2000, 1.1%/year since 2012).
  • Important energy efficiency progress was achieved in rail transport (2.4%/year) and domestic air (1.1%/year).

Energy efficiency index by mode (EU)

  • Discrepancies in energy efficiency gains in EU countries: from around 3%/year in Greece and Romania to less than 0.5%/year in Czechia, Luxembourg, The Netherlands, Belgium and Denmark.
