Aid is granted in the form of a capital grant or interest relief.

Who is concerned

Businesses concerned

The financial aid is available to any business or natural person holding a business permit.

Eligible costs

An applicant's guide (guide du requérant) is made available to help fill in the application.

The financial support scheme provides for several types of investment (schemes) which may be eligible for public financial aid:

  • investments enabling businesses to exceed EU environmental protection standards or to increase the level of environmental protection despite the absence of such standards;
  • early adaptation to future EU standards;
  • investments in energy efficiency measures;
  • investments in high-efficiency cogeneration;
  • investments in the production of energy from renewable energy sources;
  • investments in the remediation of contaminated sites;
  • investments in the district heating or cooling distribution network;
  • investments in the recycling or re-use of waste;
  • investments in energy infrastructures;
  • aid for environmental studies.


All businesses which meet the general conditions that apply to State aid are entitled to this type of aid.

How to proceed

Filing an application

In any case, aid applications must be submitted prior to starting the works, i.e. before:

  • the beginning of construction works in relation with the investment;
  • the first legally binding order of equipment or any other commitment making the investment irreversible.

The purchase of land and the preparatory work such as applying for and receiving authorisations and carrying out feasibility studies are not considered as a commencement of works.

In the case of a repurchase of assets, the commencement of works is the moment the assets which are directly related to the acquired establishment are purchased.

Applicants have to complete the application form for investment aid for a project on environmental protection and join the supporting documents listed in the form.

They can use the applicant's guide (guide du requérant) in force at the time of the application to compile their application file.

Once the application is completed and signed by a person authorised to sign on behalf of the company, the application must be submitted in electronic format or sent by post to the Ministry of the Economy. In the event of a submission by post, the following must be indicated on the envelope:
