"Transport is likely the hardest economic sector to decarbonise. And road
vehicles produce the most greenhouse gas emissions of the Australian transport
sector – 85% of its total. Freight trucks account for only 8% of travel on our
roads but 27% of transport emissions.
We analysed the life-cycle greenhouse gas emissions of Australian passenger
cars and SUVs in a 2022 study. We have now looked at Australian trucks.
The 2022 study showed Australian electric cars already provided large cuts in
emissions in 2019. The reduction was 30-40% compared to the overall on-road
passenger vehicle fleet’s (life-cycle) emissions per kilometre in 2018. When
renewables take over the electricity grid from which battery electric vehicles
are charged, the cuts will be even bigger – around 75-80%.
Is it the same for Australian trucks? Our new study shows battery electric
trucks are the best road transport option for getting closer to net-zero
emissions. As the shift to renewables continues and batteries become more
durable, these trucks are expected to deliver the largest and most certain
emission cuts of 75-85% over their entire life cycle.
Hydrogen-powered (fuel cell) trucks also provide large emission cuts, but not
as much as battery electric trucks. Their future performance is the most
uncertain at this stage."
