Ireland’s latest HVO report puts a sharper focus on where hydrotreated vegetable oil should be used to deliver the biggest climate benefit. Published on gov.ie by the Department of Transport on 7 August 2026, the new analysis examines the hierarchy of use of HVO across transport and other sectors, helping policymakers, businesses and public bodies understand where this renewable fuel makes the most sense.
The report looks at HVO in the context of limited renewable energy supply, competing sectoral demand and the availability of zero-emission alternatives. In simple terms, it asks a crucial national policy question: where should HVO be prioritised when electrification or other cleaner options may already exist?
gov.ie publishes new HVO report for Ireland’s transport transition
The publication outlines the most efficient use of HVO across all transport modes, while also considering non-transport applications. This matters for departments and agencies working across Climate Action, Transport, Finance and Public Expenditure, as well as state bodies such as the National Transport Authority (NTA), Environmental Protection Agency (EPA) and the Office of Government Procurement (OGP).
Because HVO is a renewable diesel substitute, it is often seen as a practical short-term emissions reduction tool. But the report signals that Ireland must be selective. If battery-electric, rail, or other zero-emission solutions are already viable, HVO may be better reserved for harder-to-abate uses.
- It evaluates HVO use across transport modes
- It compares HVO with available zero-emission alternatives
- It also considers demand from non-transport sectors
- It supports evidence-based decision-making for public policy
Why the hierarchy of use matters
The core idea behind the HVO report is efficiency. Renewable fuels are not unlimited, so using them where they replace fossil energy most effectively is critical. This aligns with broader Irish government priorities involving the Department of the Taoiseach, Revenue Commissioners, Central Bank, CSO and agencies supporting national decarbonisation and infrastructure planning.

What the HVO report could mean for transport, industry and government planning
The release of the HVO report may help shape future decisions across public transport, freight, heavy-duty vehicles and sectors where immediate electrification is more difficult. Bodies linked to road safety, regulation, procurement and service delivery — including the Road Safety Authority (RSA), Health Service Executive (HSE), Workplace Relations Commission (WRC) and An Garda Síochána — all operate in an environment where fleet decarbonisation is becoming more urgent.
For policymakers, the report offers a framework rather than a blanket endorsement of HVO. That distinction is important. It suggests renewable fuel policy should sit alongside investment in charging, public transport, clean technology and smarter energy allocation.
- Prioritise HVO where alternatives are limited
- Accelerate zero-emission solutions where they are already practical
- Use evidence to guide sector-by-sector fuel choices

Key facts from the publication
The HVO report was published by the Department of Transport on 7 August 2026 and is available through gov.ie. Its focus is the hierarchy of use of HVO across transport and other sectors, with particular attention to efficient deployment relative to renewable energy availability and zero-emission alternatives.
Conclusion
The publication of this HVO report marks an important step in Ireland’s cleaner transport planning. By using the HVO report to identify where renewable fuels add the greatest value, gov.ie and the Department of Transport are reinforcing a more targeted, practical approach to decarbonisation — one that balances immediate emissions cuts with long-term zero-emission progress.
