High-speed rail presents major opportunities for decarbonisation of transport
2017/12/07

7 December 2017
High-speed rail (HSR) passenger activity totalled 625 billion passenger kilometres in 2015 with China, Europe and Japan together accounting for 95% of the global total. HSR is also the fastest growing passenger rail transport service worldwide - while global high-speed rail activity has grown steadily since 2005, growth accelerated to nearly 70% over 2013 to 2015, mainly as a result of a surge in China.

This shift to HSR represents an opportunity as the rail sector can play a key role in reducing CO2 emissions from transport, particularly in being able to displace short haul aviation.

The efficiency of rail is significant in relation to other modes of transport. For example, the railway sector accounted for over 6% of global passenger transport activity in 2015, yet was responsible for less than 2% of transport final energy demand and just over 4% of CO2 emissions from the transport sector. This is due to not only better energy efficiency of the rail sector compared to the road sector, but also a continued increase in rail’s dependence on electricity - and particularly renewables.
