The first delivery is scheduled for 2026 and will be used in the latest generation of the Alstom Metropolis metro cars**. The partnership supports both companies’ ambitious climate targets and SBTi commitment and contributes to Europe’s goal of becoming climate-neutral by 2050.
“Remaining competitive and accelerating the green transition is fundamental to Europe’s future. Stainless steel is the most versatile industrial material, heavily needed for transportation solutions to reduce emissions and playing a vital part also for innovation and technological progress. Europe needs frontrunner companies throughout the value chain to drive the green transition forward. We are excited to take the next step with Alstom to support our customers’ decarbonization journey. The Circle Green contract with Alstom is volume-wise the biggest for us in the mobility sector and is due to be used in a first metro car project in Europe,” saidRolf Schencking, president for Business Line Advanced Materials at Outokumpu.
The collaboration between Outokumpu and Alstom supports Alstom’s goal to reduce emissions from procured goods and services with 30% by 2030. It will enable Alstom to integrate a higher steel scrap content rate in its products.
“Outokumpu’s Circle Green will be used for the outer layer of the metro cars. Our partnership is fully in line with the eco-design process we have applied for years for the design of our products and services. Using stainless steel with lower carbon emissions compared to standard steel will contribute in our efforts to significantly reduce our CO₂ emissions,” said Véronique Andriès, sustainability and CSR vice president at Alstom.
*Global average carbon footprint of stainless steel (2024): 7 kg CO₂e per kg of stainless steel (Outokumpu’s calculation based on data provided by CRU, worldstainless, and Kobolde & Partners AB). Outokumpu Circle Green CO₂ emissions: down to 0.5 kilos of CO₂e per kg of stainless steel. For the specific Alstom collaboration, Outokumpu Circle Green reached a reduction of up to a minimum of 85% lower carbon footprint compared to the global industry average, without compromising the superior stainless steel product features.
