A Fuel Mandate? Here’s What the Federal Budget Actually Said About Renewable Diesel
“
We will introduce a demand measure that provides certainty for new Australian low carbon liquid fuel production and stimulates investment in new, clean fuel refining capacity.”
If you procure diesel for a fleet, a construction site or a mine, you’ve probably heard “mandate” floated around renewable diesel this year. The 2026–27 Federal Budget, handed down in May gave that conversation more substance, but it did not announce a renewable diesel mandate. Here’s what was actually announced, what it means, and why it matters for businesses using or considering renewable diesel (HVO).
What the Budget Actually Committed To
The Budget confirmed that the Government will work with industry to introduce a demand measure for low carbon liquid fuels (LCLF). In practice, that means the Commonwealth wants to create stronger and more predictable demand for Australian-made low carbon fuels, including renewable diesel and sustainable aviation fuel (SAF).
That commitment sits alongside the $1.1 billion Cleaner Fuels Program, which is designed to support domestic production of low carbon liquid fuels. It also sits within the broader fuel security package announced in the Budget.
What was not announced was a quota, start date or compliance design. The Budget signals intent, not an operational rule.
Why “Demand Measure” Is Not Necessarily A Mandate
A mandate and a demand measure are related, but they are not the same thing. A mandate usually means a fixed legal obligation, such as a blending requirement or usage target. A demand measure is broader and could take several forms, including a mandate, procurement settings, incentives or other policies that create a market for low carbon fuels.
That distinction matters because the Budget did not lock in the policy design. It opened the door to one or more mechanisms, but it did not spell out how compliance would work.
The legislative pathway is also still unsettled. The Budget gives little indication of the Government's preferred approach, and given objectives spanning fuel security, domestic production, refining capacity and decarbonisation, implementation may draw on a combination of legislative instruments rather than a single statute – for example, amendments to existing fuel security and fuel quality legislation for a supply-obligation model, or a bespoke framework if the Government instead pursues a certificate-based market.
What Already Exists
Prior to the budget, there was no national rule requiring industry to use renewable diesel today. Industries like mining remain under the general Safeguard Mechanism, not a fuel-specific federal obligation.
State policy is different. For example, the NSW EPA has proposed coal mine licence conditions that would progressively reduce diesel emissions and require lower-emissions alternatives over time.These proposals are still separate from any federal low carbon liquid fuels policy. Queensland has a biofuels mandate for fuel sellers, which requires 0.5% of all diesel fuel sold by fuel wholesalers to be biobased diesel (biodiesel).
Moving forward, the consideration of possible mechanisms isn’t new. Back in 2024, the Department of Infrastructure ran a public consultation - ”A Future Made in Australia: unlocking Australia's low carbon liquid fuel opportunity”. That process tested industry appetite for several demand-side mechanisms and helped inform the Government's March 2025 decision to allocate $250 million toward LCLF innovation, and ultimately the Budget's commitment to introduce a demand measure. The options it canvassed at the time were:
A hard mandate – a fixed minimum proportion of LCLF in fuel supply, increasing over time, similar in structure to the EU's ReFuelEU aviation mandate.
A low carbon fuel standard – a performance-based carbon-intensity requirement across the fuel mix, with tradeable credits for flexible compliance (closer to schemes like California's LCFS).
Non-binding targets – voluntary uptake goals without a regulatory enforcement mechanism.
A sector-limited approach – applying any of the above only to certain sectors (aviation is the most likely starting point) or to businesses above a size threshold.
Where Australia Stands Globally
Globally, mandatory renewable fuel blending in road transport is already common. Aviation has moved even faster with several regional economies having already moved:
Singapore: 1% SAF requirement from 2026, rising to 3-5% by 2030
South Korea: 1% mandate for international uplift from 2027
Japan: consulting on a 10% SAF target by 2030
Indonesia, Malaysia, India, Thailand: mandates or roadmaps in place or in development
Industry Reaction
Industry reaction has been generally supportive, but cautious. The positive takeaway is that a demand measure gives producers and investors more certainty than supply support alone.
The caution is that the Budget still does not say what the measure will be, when it will start or which sectors will be covered. Design work is expected to feed into the Transport and Infrastructure Net Zero Roadmap, with commentary since the Budget suggesting the broader policy design process could run for a further 12–24 months before an operational scheme is settled. Until those details are published, this remains a policy direction rather than a compliance obligation.
What It Means for HVO Users
The Budget did not announce a fuel mandate. It confirmed that the Government wants to create a demand measure for low carbon liquid fuels, which is an important policy signal - but still not a rule.
For now, nothing changes in day-to-day supply, pricing or compliance. If you are already using HVO, the Budget does not impose any new requirement on your business today.
