Voestalpine has signed a new agreement with Siemens Mobility to expand the use of CO2-reduced steel in rail vehicle manufacturing. Under the deal, roughly 20pct of the steel Siemens will use in 2025 will come from Voestalpine’s Greentec Steel Edition, with an option for additional volumes over the next three years.
The partnership builds on the “Green Steel for Bogies” pilot launched in 2022 at Siemens Mobility’s global bogie competence center in Graz. The facility produces around 3,000 bogies annually, and an increasing share will now incorporate Voestalpine’s low-emission steel, a key step toward more sustainable rail transport.
Produced at Voestalpine’s Linz site, Greentec Steel Edition products use a CO2-optimized process that cuts emissions by up to 70pct compared to conventional steelmaking. Siemens Mobility already employs CO2-reduced steel in bogies, locomotives, and passenger coaches, with plans to gradually expand its use across operations.
This collaboration supports Siemens Mobility’s sustainability targets, a 90pct reduction in operational CO2 emissions by 2030 and net-zero across its value chain by 2050. Voestalpine also issued Siemens Mobility a greenhouse gas (GHG) emissions certificate for supplied materials, ensuring full transparency and traceability throughout the supply chain.
