Australia's light-vehicle fleet is undergoing change, with the pace increasingly influenced by the alignment of vehicle technology, market availability, and government policy.

Recent research from the National Transport Commission (NTC) indicates that emissions intensity from new light vehicles has declined over the past two years, representing some of the largest reductions observed in more than two decades. This change is associated with the growth in electric and hybrid vehicle adoption, supported by policies that have improved accessibility to these vehicles.

New-vehicle decisions have the greatest impact

The NTC's analysis tracks emissions intensity over time using new-vehicle sales data, showing that current purchasing decisions determine emissions outcomes for decades. With light vehicles typically remaining in service for close to 20 years, improvements at the point of sale are significant.

Data indicates that battery electric vehicles (BEVs) accounted for approximately 13% of new registrations in 2024, with the majority added to the fleet since 2021. Hybrid vehicles have also increased in number, contributing to emissions reductions across passenger vehicles and SUVs.

Although internal combustion engines continue to dominate the overall fleet, the report confirms that emissions from new vehicles are declining, a trend aligned with the expansion of EV options and supporting policy frameworks.

Policy signals are influencing fleet behaviour

According to the National Automotive Leasing and Salary Packaging Association (NALSPA), the timing of these emissions reductions is linked to government policy.

"The rise in EV uptake and the decline in Australia's vehicle emissions coincide with the introduction of the EV FBT exemption," stated Rohan Martin, Chief Executive of NALSPA.

"The EV tax reduction has lowered the upfront cost of electric vehicles, making them more accessible to a broader range of Australians. Many workers, including teachers and nurses, report that they would not have transitioned without the assistance provided by the FBT exemption."

NALSPA's data indicates that uptake has been higher in outer metropolitan areas, where longer commutes increase the impact of fuel and running-cost savings.

"Families in outer suburbs are adopting the EV tax cut at higher rates. Running-cost savings are particularly relevant in these areas, where residents face longer commutes and higher fuel expenses," Martin added.

Progress achieved, but challenges remain

Despite recent gains, the NTC report notes that Australia remains in the early stages of vehicle electrification. Electric vehicles represent only around 2% of the total light-vehicle fleet, and the country continues to lag behind international markets in emissions performance.

On average, new passenger vehicles sold in Australia emit approximately 35% more CO2 than their European equivalents, reflecting both vehicle choice and slower historical adoption of electrified powertrains.

"Supporting the transition to more fuel-efficient vehicles through novated leasing and the EV FBT tax cut is important for reducing emissions and meeting national targets," Martin stated.

"Novated leasing contributes to emissions reductions by enabling more frequent replacement with newer, more efficient vehicles, supporting turnover into lower-emission models."

The role of fleets in the transition

For fleet operators, fleet purchasing decisions are among the most direct mechanisms to influence national emissions outcomes. Fleets generally acquire newer vehicles more frequently, which accelerates the adoption of lower-emission technologies and affects the used-vehicle market over time.

Independent modelling by Magenta Advisory, cited by NALSPA, indicates that extending the EV tax cut for a decade could halve vehicle emissions compared with ending the policy earlier, while generating over AUD 2 (US$ 1.30) in economic, health, and environmental benefits for every AUD 1 invested, increasing to AUD 3 by 2030.

"Maintaining the EV tax cut supports continued adoption of new EVs and increases the availability of second-hand EVs," Martin explained. "International data shows that EV uptake is most effective when buyer incentives are paired with supply measures until key benchmarks are reached."

Alignment is influencing change

The NTC report demonstrates that Australia's fleet transition is influenced by the combination of policy, market supply, and fleet economics, rather than technology alone.

For fleets planning their next replacement cycle, the data indicates that decisions made today will determine emissions, costs, and operational performance into the 2030s and beyond.
