| Affected parties | Environmental NGOs, companies receiving state aid and public administrations in the EU |

Companies receiving state aid in sectors with environmental impact—energy, industry, transport, agriculture, infrastructure—face a new regulatory risk from 13 June 2025. The Implementing Regulation (EU) 2025/905, which amends Regulation (EC) No 794/2004, activates an internal review mechanism that responds to the conclusions of the Aarhus Convention Compliance Committee in matter ACCC/C/2015/128.
The corrigendum published on 17 July 2026 corrects technical and drafting errors in the original text, but does not alter the substance of the regulatory change: environmental NGOs now have a formal avenue to question European Commission decisions on state aid.
What does this regulation establish?
The Aarhus Convention guarantees access to information, public participation and access to justice in environmental matters. Matter ACCC/C/2015/128 specifically questioned that environmental organizations did not have an effective avenue to challenge before the European Commission its own decisions on state aid with environmental impact.
Regulation (EU) 2025/905 resolves this gap by introducing an internal review mechanism within the procedure regulated by Regulation (EC) No 794/2004. The specific changes compared to the previous regulation are:
| Aspect | Before (original Regulation EC 794/2004) | After (with Regulation EU 2025/905) |
|---|---|---|
| NGO access to decision review | No formal mechanism specific to environmental organizations | Internal review mechanism enabled for environmental NGOs |
| Aarhus Convention follow-up | No follow-up procedure for matter ACCC/C/2015/128 | Procedure incorporated into state aid procedures regulation |
| Procedural updates | Text without procedural updates from Regulation 2025/905 | Other procedural updates included in the same Regulation |
The corrigendum published in July 2026 does not modify the substance of these changes: it only corrects technical or drafting errors detected after the original publication on 13 June 2025.
Economic and operational impact
The impact is not a direct fine or fixed cost. The risk is operational and legal certainty: state aid already approved by the European Commission can be subject to internal review at the request of an environmental NGO, which may result in:
- Suspension or revision of the aid granted, with the consequent impact on the financial planning of the beneficiary company.
- Legal and management costs to defend the compatibility of the aid received with environmental regulations.
- Project delays financed wholly or partly with state aid if the decision is suspended during the review process.
- Greater reputational scrutiny for companies in sectors with high environmental exposure.
For public administrations that notify aid to the Commission, the change means incorporating the environmental dimension as a more rigorous prior analysis element, anticipating possible review requests.
Who does it affect?
- Companies receiving state aid with environmental impact: especially in energy, heavy industry, transport, agriculture and large infrastructure sectors.
- NGOs and environmental organizations: obtain a formal avenue to request internal review of European Commission decisions, without needing to go directly to courts.
- Public administrations that notify state aid to the European Commission: must anticipate environmental analysis in their notification files.
- Legal advisors and consultants specialized in state aid and European environmental law.
- CFOs and financial directors of companies that have received or are processing state aid in sectors with environmental component.
Practical example
A company in the industrial sector receives state aid approved by the European Commission to modernize a production plant. The investment has an environmental component: the plant is located near a protected area and the project involves emissions during the construction phase.
With the new mechanism activated by Regulation (EU) 2025/905, an environmental organization that believes the Commission did not correctly evaluate the environmental impact when approving that aid can submit a formal internal review request to the Commission itself. If the review succeeds, the company could see the aid already granted conditioned or revised, with direct impact on its business plan and financing.
This scenario, previously without clear procedural avenue, is now a real and formalized risk that must be incorporated into the regulatory risk analysis of any company receiving state aid in sectors with environmental dimension.
What should companies do now?
- Identify if you receive or process state aid with environmental component: review whether the aid received or in process involves impact on the environment, protected areas, emissions or natural resources.
- Evaluate exposure to the new review mechanism: assess with your legal advisor whether the Commission decision that approved your aid could be subject to an internal review request by an environmental NGO.
- Incorporate environmental regulatory risk into financial planning: if there is exposure, consider scenarios of review or partial suspension in your projections.
- Strengthen environmental documentation of aid files: whether you are a beneficiary company or a notifying administration, ensure that environmental analysis is correctly documented and justified in the file.
- Follow the evolution of procedure ACCC/C/2015/128: the conclusions of the Aarhus Convention Compliance Committee in this matter are the origin of the change and may generate additional developments.
Frequently asked questions
What is the internal review mechanism of Regulation EU 2025/905?
It is a formal procedure by which environmental organizations can request the European Commission to review its own decisions on state aid when they consider that they have an environmental impact not correctly evaluated. This mechanism is introduced in Regulation (EC) No 794/2004 in response to the conclusions of the Aarhus Convention Compliance Committee in matter ACCC/C/2015/128.
Since when can NGOs request internal review of state aid?
The mechanism has been in force since 13 June 2025, the date of entry into force of Implementing Regulation (EU) 2025/905. The corrigendum published on 17 July 2026 does not modify this date or the substance of the mechanism.
Can an NGO challenge state aid that has already been approved and received?
The internal review mechanism allows environmental organizations to request review of European Commission decisions, including those already adopted. If the review succeeds, the Commission could reconsider its decision, which could affect aid already granted. The beneficiary company should evaluate this risk with its legal advisor.
Which sectors have the greatest risk of having their aid reviewed?
The sectors with the greatest exposure are those with direct environmental impact: energy (especially fossil fuels or large infrastructure), heavy industry, transport, intensive agriculture and construction or infrastructure projects in sensitive areas. There is no closed list in the regulation: the criterion is the existence of environmental impact in the aid decision.
What is matter ACCC/C/2015/128 of the Aarhus Convention?
It is a case processed before the Aarhus Convention Compliance Committee in which it was questioned that environmental organizations did not have effective access to justice against European Commission decisions on state aid. The conclusions of that committee are the direct origin of the internal review mechanism introduced by Regulation (EU) 2025/905.
