From 1 January 2025, the specific aid for environmental protection and energy use will be renamed "GREEN aid". This reform is designed to encourage sustainable investment and strengthen companies' environmental commitments. In addition to the name change, this reform introduces new conditions for access, revised financing levels, a redefinition of eligible investments, a new procedure for settling the premium, and a new premium for cooling units.
The GREEN reforms will introduce several new features from 1 January 2025:
new name
the specific aid for environmental protection and energy use will be renamed "GREEN aid"
access conditions
- Eligibility of ASBLs with an economic vocation: ASBLs with an economic vocation will now have access to aid.
- Additional conditions for specific "sustainable energy use" (SEU) aid:
- Obligatory AMUREBA audit or feasibility study: Companies must undergo an AMUREBA audit or feasibility study in line with AMUREBA methodology, carried out by a certified auditor in accordance with the required procedures. This audit or study must cover the investments presented and is required for the submission of the investment aid application form. AMUREBA audits may be eligible for energy vouchers.
-
This condition is being phased in gradually:
- Energy savings in the production process:
- in 2025, for investment programmes over €25,000.
- in 2026, for all programmes.
- In the renewable sector:
- in 2025, for investment programmes over €100,000.
- in 2026, for all programmes.
- Installation of energy meters: companies must undertake to install energy meters to measure energy production or savings linked to the investments presented, at the latest by the end of the investment programme.
- Energy accounting: By the end of the investment programme at the latest, companies must undertake to carry out energy accountancy so that the effects of the investment can be measured objectively.
- Return on investment time: In terms of energy savings in the production process, investments must have a discounted return on investment time of more than three years, calculated using the AMUREBA methodology.

- Investments to comply with European Union standards already adopted and in force
- Investments in photovoltaics, biomethanisation with a unit capacity of less than 10 kW and wind power with a unit capacity of less than 50 kW and more than 1,000 kW.
- Cogeneration investments
- solid biomass turbines with a nominal unit capacity of more than 5,000 kWel
- solid biomass by gasification with a nominal unit capacity of more than 5,000 kWel
- liquid biomass
- investments in renewable hydrogen production
- investments in energy savings in the production process, whose discounted return on investment time of less than or equal to three years, calculated using the AMUREBA methodology.
- investments in renewable electricity storage
Payment of the grant
The investment threshold for the payment of the first 50% grant instalment is now set at €500,000. When the eligible investment is less than €500,000, the grant is paid in a single instalment once the investment has been completed.
Conditions for payment of the full/balance grant:
- Proof of having achieved the objectives set out in the convention or decision:
- Through an AMUREBA performance audit for investments in sustainable energy use.
- Through an inspection by experts or laboratories for investments in environmental protection.
- For investments in sustainable energy use:
- proof of having carried out an AMUREBA audit or feasibility study on the investments presented.
- proof of having energy meters to enable the objective measurement of the energy impact of the investments presented.
- proof of energy accounting.
New grant: cooling units
In brief: Aid for the replacement and modernisation of refrigeration systems has been updated following the phasing-in of European requirements to remove refrigerants that have a significant impact on global warming.
Eligible investments:
- commercial plants over 40 kWth using CO2 or NH3.
- non-commercial plants over 40 kWth using NH3, CO2 or propane.
- commercial and non-commercial plants under 40 kWth using CO2, NH3 or propane.
- energy-efficient counters.
- energy-monitoring systems installed to monitor cooling units.
Obligation to keep a register: To submit an application for investment aid, it is compulsory to keep a maintenance register (electronic or paper).
