Transport emissions: how Australia’s states and territories compare

Transport is a major source of greenhouse gas emissions in Australia. Several factors affects transport emissions across Australia's states and territories, including population size, urban planning, geographic challenges, and transport policies.

New South Wales

Has one of the highest transport emissions in Australia, largely due to its significant population and extensive road network, leading to high levels of vehicle use and congestion.


Also reports high transport emissions, with Melbourne's sprawling urban area and heavy reliance on road transport contributing significantly to the state's greenhouse gas output.


Exhibits high transport emissions, driven by the state's large geographic area, which necessitates extensive road transport, and a heavy reliance on road freight.

Western Australia

Despite its lower population, WA has considerable transport emissions due to long travel distances and a strong dependence on road and air transport, especially in remote areas.

South Australia

Has relatively moderate transport emissions, influenced by Adelaide's compact urban form and the state's efforts to promote public transport and cycling.


Reports lower transport emissions compared to other states, benefiting from its smaller population, lower vehicle usage, and efforts to increase the use of renewable energy in transport.

Australian Capital Territory

Has the lowest transport emissions, attributed to its small size, well-planned urban infrastructure, and aggressive policies to promote electric vehicle use and public transport.

Northern Territory

Despite its small population, the NT has high per capita transport emissions, largely due to the reliance on road transport across vast distances and limited public transport options.
