Too big, too heavy and too slow to change: road transport is way off track for net zero

"The need to cut the emissions driving climate change is urgent, but it’s
proving hard to decarbonise road transport in Australia. Its share of the
nation’s total greenhouse gas emissions doubled from 8% in 1990 to 16% in 2020.
New vehicles sold in Australia have barely improved average emissions
performance for the last decade or so.

The federal government publishes emission forecasts to 2035 – 15 years short of
2050, the net-zero target date. Our newly published study forecasts road
transport emissions through to 2050. The estimated reduction by 2050, 35–45% of
pre-COVID levels in 2019, falls well short of what’s needed.

Our findings highlight three obstacles to achieving net zero. These are:
Australia’s delay in switching to electric vehicles; growing sales of large,
heavy vehicles such as SUVs and utes; and uncertainties about hydrogen as a
fuel, especially for freight transport. These findings point to policy actions
that could get road transport much closer to net zero."
