Ireland’s transport decarbonisation plans took another step forward as gov.ie confirmed the publication of a new report setting out how Hydrotreated Vegetable Oil, or HVO, should be prioritised across transport and other parts of the economy. The new HVO report signals that while renewable fuels can help cut emissions in the near term, limited supply means government policy must direct HVO to the sectors that need it most.
Published by the Department of Transport on 7 August 2026, the report examines rising demand for HVO and assesses how State policy can support the most efficient use of this renewable fuel both before 2030 and in the years beyond. The work is part of a broader evidence-based approach being developed across government departments and agencies as Ireland works toward Climate Action and European decarbonisation targets.
gov.ie HVO report sets out priorities for scarce renewable fuel
The central message of the report is clear: HVO should be treated as a transitional and strategically limited resource. Rather than being used everywhere, the fuel should be prioritised where electrification or other zero-emission alternatives are less available.
According to the Department of Transport, this approach reflects the practical challenge of balancing:
- decarbonisation goals
- energy security
- affordability
- sustainability requirements
- supply constraints in renewable fuels
The report supports the view that biofuels such as HVO remain important in the short term, especially for hard-to-abate areas including aviation, freight and maritime transport. That position also fits with wider policy frameworks involving Climate Action, Transport and Public Expenditure planning.
Why HVO still matters in Ireland’s transport mix
Although electrification remains the long-term direction of travel, HVO can help reduce emissions during the transition. This matters for sectors where battery-electric or other clean technologies are not yet fully scalable. The report therefore aligns with several policy strands, including the Renewable Transport Fuel Policy, the Road Haulage Strategy, ports planning and sustainable aviation fuel measures.
The findings are likely to be relevant not only to the Department of the Taoiseach and Finance discussions around climate investment, but also to agencies and public bodies monitoring infrastructure, regulation and industrial transition.

How the Revenue Commissioners, NTA and other bodies may watch the outcome
While the report comes from Transport, its implications stretch much wider. Bodies such as the National Transport Authority (NTA), Revenue Commissioners, Environmental Protection Agency (EPA), Central Bank and enterprise agencies will all have an interest in how renewable fuel use affects costs, compliance, logistics and investment decisions.
Other sectors named in the wider public policy landscape, from Housing and Local Government to Enterprise, Trade and Employment, may also monitor future decisions where HVO intersects with construction, fleet management and supply chains. In practical terms, the hierarchy is expected to help policymakers decide where support measures should be concentrated if fuel availability tightens.
Stakeholder input shaped the final recommendations
The research was carried out by Ricardo consultants between October 2025 and May 2026. Officials from the Department of Transport and the Department of Climate, Environment and Energy oversaw the process through a dedicated working group, supported by engagement with suppliers, distributors, brokers, industry groups and government bodies.
That collaborative method gives the report additional weight, especially as agencies such as the Workplace Relations Commission (WRC), Health Service Executive (HSE), An Garda Síochána and other public service fleet operators continue exploring lower-carbon operational models.

What the HVO report means for Irish climate policy
The gov.ie publication does not suggest HVO is a permanent solution. Instead, it reinforces that renewable liquid fuels should bridge the gap while Ireland scales up electrification and other zero-emission technologies. That makes the hierarchy important: it helps ensure a scarce renewable resource is used where it can deliver the greatest system-wide value.
For policymakers, transport operators and industry, the takeaway is straightforward. The gov.ie HVO report provides a roadmap for smarter fuel allocation, helping Ireland stay aligned with European obligations while keeping focus on the longer-term shift away from fossil fuels.
