Environmental Assessment

Verified 03 September 2025 - Directorate of Legal and Administrative Information (Prime Minister)

One environmental assessment is required for projects which, by their nature, size or location, are likely to have significant impacts on the environment or human health. We present the step-by-step approach.

Step-by-step approach

Submission for environmental assessment

Prior to the start of the work, the project owner must check if your project is subject to an environmental assessment.

An environmental assessment is required for projects that, by their nature, size or location, are likely to have significant impacts on the environment or human health.

In order to determine whether the project is systematically subject to environmental assessment, whether it can be subject to environmental assessment (case-by-case review), or whether it is not, consult the environmental assessment nomenclature :

Where the same project falls under several items in the nomenclature, a environmental assessment is required once the project reaches the thresholds and fulfills the conditions of one of the applicable entries. In this case, a single environmental assessment must be conducted for the project.

It is also possible to ask the competent service, which differs according to the location of the project:

Guadeloupe, Martinique, Reunion Island, Mayotte

The department to be contacted is the Department of the Environment, Planning and Housing (DEAL):

The department responsible for authorizing the project may decide to examine on a case-by-case basis the projects submitted to it, the thresholds of which are lower than those laid down in the nomenclature. It must inform the developer of its reasoned decision to submit the project for examination on a case-by-case basis, no later than 15 days from the filing of the file of that application or declaration.

Modifications or extensions of projects already authorized, which enter them, in their totality, within the thresholds laid down in the nomenclature or which in themselves reach those thresholds must be subject to an environmental assessment or a case-by-case examination.

Other modifications or extensions of projects subject to systematic environmental assessment or subject to a case-by-case review, which may have significant negative effects on the environment, shall be subject to a case-by-case review.

With some exceptions, maintenance and major repairs, regardless of the projects to which they relate, are not subject to environmental assessment.

The contracting authority may also, on its own initiative, carry out a request for case-by-case review with the competent service, for any project below the thresholds fixed by the nomenclature.

Case-by-case review

For projects falling under a case-by-case review according to the bill of materials, the developer shall describe :

  • The characteristics of the whole project, including any demolition work
  • The significant impacts that his project is likely to affect the environment and human health
  • If there are, the measures and the characteristics of the project intended to avoid or reduce its likely significant adverse effects.

When the same project is a matter of both a systematic environmental assessment and a case-by-case review under one or more headings of the nomenclature, the contracting authority is waived the need to follow the examination procedure on a case by case basis.

The impact assessment then covers all the impacts of the project, including construction, plant or works or other interventions that, taken separately, would be below the threshold for a case-by-case review.

The request for a case-by-case examination can be made online or by post. It is advisable to prioritize the online procedure.

Online

The request may be made by the contracting authority via the following online service :

Request for a case-by-case review prior to conducting a potential environmental assessment

By mail

For projects submitted for examination on a case-by-case basis, an application may be made by the developer by completing the following form :

Request for a Pre-Impact Assessment (Environmental Assessment)

This form must then be transmitted electronically or by registered mail the department responsible for the case-by-case examination, which shall acknowledge receipt thereof.

Disbursement of raw biodiversity data

Project promoters who have carried out an impact assessment must transmit raw biodiversity data acquired during the evaluation studies of their project.

The disbursement of raw biodiversity dataacquired during the impact assessment must be carried out before the public participation procedure starts.

This payment takes place via projects-environment.gouv.fr or via the online service Depobio :

Depobio: platform for the legal deposit of biodiversity data

Inventories carried out as part of the description of the initial status and the assessment of the significant direct and indirect impacts of a project on biodiversity must have been completed or updated less than 5 years prior to the date of filing for which they are required.

These inventories can be used as a description of the initial status for changes to the project and for other projects in the same inventory area. They can be used for the assessment of significant impacts on biodiversity of projects with similar potential impacts.

Where the prefecture considers that the inventory is insufficient in view of the project's impact or that new ecological issues arise, it may request the necessary additions or updates.

Process and objectives

Environmental assessment allows for describe andenjoy in an appropriate manner, according to each particular case, the significant direct and indirect impacts of a project the following factors:

  • Population and human health
  • Biodiversity, with special attention to protected species and habitats
  • Land, soil, water, air, energy consumption and climate
  • Physical assets, cultural heritage and landscape
  • Interaction between these factors.

The developer shall take into account the impacts resulting from the vulnerability of the project to major accident risks and disasters, where these are relevant to the project concerned.

Example :

Releases to the environment, habitats destroyed by the project, etc.

Submission of the environmental assessment application

The environmental assessment must be filed via an online service, accompanied by the impact assessment:

Consultation and submission of projects subject to impact assessment (Environmental Assessment)

It will thus be transmitted to the competent service, as well as to the local authorities and their groups interested in the project.

The developers must make available to the publicat the latest at the time of the opening of the public inquiry or of the public participation by electronic means:

  • The impact assessment. The impact assessment file shall be accompanied by a file of the raw environmental data used in the study, in an open and easily reusable format, i.e. machine-readable and usable by standardized data processing.
  • The written response which they formulated following the opinion of the prefect.

Please note

When a project consists of several works, installations, works or other interventions in the natural environment or landscape, it must be apprehended as a whole, including in the case of time and space splitting and in the case of a multiplicity of developers, so that its environmental impact is assessed in its entirety.

The competent department shall decide within 2 months of the date of receipt of the file including the impact assessment and the application for authorization.

Local and regional authorities and their groups interested in the project may be consulted and give opinions on the application. The competent department shall forward these notices to the developer as soon as it receives them.
