1. Report Publication and Purpose
Constellium published its 2025 Sustainability Report detailing initiatives to advance a sustainable and circular aluminum economy. The report highlights innovation in decarbonization, increased recycling efforts and a commitment to safety and customer delivery across its global operations.
2. Emissions Reduction and Recycling Center Ramp-Up
Overall emissions intensity (scope 1, 2 and 3) fell by 16% versus 2024, driven by a 14% improvement in scope 1 and 2 emissions from renewable electricity procurement and energy-efficient investments. Scrap input rose to 47% of total metal, a 13% increase, largely due to ramp-up of the new Neuf-Brisach recycling center.
