Several legal challenges have been launched against the construction of what would be the largest data center in Europe, located in Seine-et-Marne. The project, estimated to cost 50 billion euros, has drawn opposition from environmental and community groups who filed six legal actions against it. These challenges were submitted to the Paris administrative court of appeal by a coalition of associations, including France Nature Environnement (FNE), Terre de liens, the Confédération paysanne, and the Amis de la Terre. The data center is being funded by the Emirati investment fund MGX, Bpifrance, the French artificial intelligence startup Mistral, and the American tech giant Nvidia. According to the Regional Environmental Authority (MRAe), the project has "unusual characteristics" and is expected to consume up to 1.4 gigawatts of power at its peak. This would make its annual electricity use more than 2% of France’s total consumption and over 15% of that in Île-de-France. The legal challenges focus on several key aspects of the project. One concerns the modification of the local urban planning plan, another relates to the authorization given to RTE, the national electricity transmission company, for the project’s connection to the power grid. Four other challenges target the environmental authorizations granted by the prefect of Seine-et-Marne. A seventh challenge, described as "imminent," is expected to be filed regarding the building permit. The groups argue that the way the project is structured—divided into three separate blocks operated by different companies—allows the project developers to avoid certain regulatory thresholds, such as the "Seveso high threshold," which applies to facilities that handle hazardous materials or processes. Lawyer Louis Cofflard, representing the coalition, called the structure of the companies involved "baroque" and said they are "empty shells" with minimal financial backing. One of the companies reportedly has a share capital of just one euro and a single manager. Jean-François Dupont, an administrator of the FNE 77 association, echoed these concerns, calling the setup an attempt to "circumvent the regulations as much as possible." The legal process could take up to ten months, during which the construction of the site has already begun. The first phase of the data center is expected to be completed by 2028, with the entire site operational by 2038.
