The updated policy scenarios cover road transport differently. This results in higher fuel combustion emissions in transport in the Clean Energy Future scenario than in the other policy scenarios. By 2050, road transport combustion emissions in the Government policy scenario are slightly below their 2010 levels, but remain 31 per cent higher in the Clean Energy Future scenario.

Demand for biofuels and electric vehicles is substantially stronger in the Government policy scenario. By 2050, over 40 petajoules more electricity is used in road transport in the Government policy scenario than the Clean Energy Future policy scenario.
