Key results

  • For passenger trains, electricity usage increased by 5.3% and diesel usage increased by 1.5% compared to 2018-19. Over the same time period, passenger kilometres decreased by 1.3%.
  • The resulting CO2e emissions for passenger trains have fallen to 35.1g CO2e per passenger km. This is the lowest level since the comparable time series started in 2011-12.
  • The amount of diesel consumed by freight trains in 2019-20 has increased by 12.5% to 172 million litres. This is the highest figure since 2015-16, and the first time that diesel use increased year on year since 2015-16. Electricity usage fell by 6.3% to 70 million kWh.
  • The resulting CO2e emissions for freight trains have increased to 27.5g CO2e per tonne km. This is the highest level since the comparable time series started in 2011-12.
