Two legal appeals are set to be filed against the Campus IA megaproject in Seine-et-Marne, a large-scale development involving the construction of 11 massive data centers on a 90-hectare site in Fouju. According to the French business and economic news outlet Les Échos, the appeals will be submitted on September 24 and at the start of next week before the administrative court in Melun and the administrative court of appeal in Paris. These legal challenges are part of a growing opposition to the project, which has sparked environmental and urban planning concerns. The Campus IA project is funded by a 50 billion euro investment from an Emirati fund and is expected to require 1.4 gigawatts of electrical power in the long term—comparable to the power output of the EPR nuclear reactor in Flamanville. To avoid being classified under the Seveso directive, which regulates industrial sites with high risk of accidents, the project has been split into three phases. Additionally, it benefits from an accelerated approval process under the "major national interest projects" category, which allows for faster administrative decisions. The appeals are being filed by the Stop Campus IA collective, which includes environmental organizations such as France Nature Environnement and Les Soulèvement de la Terre. These groups are challenging the local urban planning plan and the environmental impact study that supported the project. Their concerns include the potential environmental damage and the impact on the local community. The opposition has gained significant traction, with an online petition gathering over 69,000 signatures in support of halting or modifying the project. The legal battle highlights the tension between large infrastructure developments and environmental protection, as well as the role of public opinion in shaping such major projects. The outcome of these appeals could have significant implications for the future of the Campus IA project and similar developments in France.
