Transport is Australia’s third-largest and fastest-growing source of emissions, accounting for 23% of the total. Without intervention, it is expected to become the leading source of emissions by 2030. The increase in transport emissions by 3.6% from 2022 to 2023 is largely attributed to a rise in on-road diesel vehicles, which have seen an 84% growth since 2014. Passenger cars and freight trucks are significant contributors to emissions, making up 44% and 23% of all transport emissions respectively. To reduce emissions, the focus has turned to electrifying vehicles, with electric trucks emerging as a more efficient and faster option compared to hydrogen trucks. Research evaluating the lifecycle emissions of low-emission trucks in Australia compared electric and hydrogen trucks across various truck types. Electric trucks showed lower emissions intensity than hydrogen trucks, with the latter sometimes emitting three times more. The study emphasized the need for a lifecycle analysis to assess the overall carbon footprints, taking into account production, use, and recycling phases. The analysis, conducted under various energy mix scenarios, indicated that a transition to a fully renewable scenario with a mix of electric and hydrogen trucks could reduce freight emissions by 76%. However, challenges in cutting emissions from manufacturing, maintenance, and disposal processes were highlighted. Industry readiness for the transition to low-emissions trucks was also examined, with concerns raised over high purchase costs and customer acceptance of green freight services. Most operators acknowledged the importance of decarbonization but expressed uncertainties about absorbing the initial costs.
