ArcelorMittal Méditerranée committed €245 million ($256 million) to environmental projects across French facilities between 2014 & 2024, achieving a 71% reduction in overall environmental impact. The investment strategy centered on the Fos-sur-Mer plant's €76 million ($79.5 million) ladle furnace installation, receiving €15 million ($15.7 million) in French government support, delivering nearly 10% CO₂ emissions reductions by 2025. Aggressive scrap metal integration reduced liquid iron consumption, cutting annual CO₂ emissions by 400,000 metric tons. The company now prepares for electric arc furnace deployment, including a €500 million ($523 million) Maridec facility representing Europe's largest steel investment in a decade, scheduled for partial commissioning by end-2025 to address European Union climate policy requirements.
