Investment aid for environmental and energy studies and advisory services
Do you want to request financial aid for an environmental or energy study or advisory service?
Under the Law of 8 December 2025, the Ministry of the Economy offers aid to companies commissioning studies or advisory services directly linked to investments eligible under the Environmental Law.
Article 12 covers the following types of studies and services:
- Environmental studies — feasibility studies, environmental impact assessments and diagnostic studies linked to eligible investments
- Energy audits — in-depth energy audits going beyond the mandatory audits required under the Law of 5 August 1993 on the rational use of energy
- Advisory services — expert advice and consultancy directly linked to an eligible environmental or energy investment
Please note: No aid may be granted for energy audits carried out solely to comply with the mandatory audit requirements of the Law of 5 August 1993. Aid is only available for audits that go beyond what is legally required.
Please note: The aid is granted regardless of whether the conclusions of the study or advisory service are followed by an eligible investment. The study does not need to lead to a funded project.
We can advise you on:
- whether your study or advisory service qualifies as directly linked to an eligible investment under the Environmental Law
- which type of study or service is covered and how to document the link to the investment
- how to prepare and submit your application via MyGuichet.lu before the study begins
Maximum amount of financial aid
The eligible costs are the full cost of the study or advisory service when it relates entirely to eligible investments. Where only part of the study relates to eligible investments, only the corresponding portion of the costs is eligible.
| Small company | Medium company | Large company | |
| Aid rate | Up to 80% of eligible costs | Up to 70% of eligible costs | Up to 60% of eligible costs |
Please note: There is no minimum aid threshold for Article 12. Unlike other articles under the Environmental Law, the EUR 50,000 and EUR 100,000 minimum thresholds do not apply.
Please note: The application must be submitted before the study or advisory service begins. Any commitment made before the application is submitted will render the application inadmissible.

The full cost of the study is eligible

No minimum aid threshold
Article 12 is explicitly exempt from the minimum thresholds that apply to other articles. Companies of any size can apply regardless of the amount of aid requested, making this measure accessible to small-scale studies and advisory missions. -
Aid is independent of the investment outcome
