Siemens Mobility increases share of “green steel” in production
With a new agreement with voestalpine, Siemens Mobility is
further increasing the share of “green steel” in its rail vehicle production.
The goal is to source around one-fifth of the steel supplied in 2025 from the
CO₂-reduced
Greentec Steel Edition of the steel and technology company voestalpine. The new
agreement also includes an option for additional quantities over the next three
years. The purchase expands the "Green Steel for Bogies" pilot
project, which began in 2022 at the Siemens Mobility global competence center
for bogies in Graz. In the future, around 3,000 bogies will be produced there
annually with an increasing proportion of CO₂-reduced material – an important step towards an even
more climate-friendly railway industry.
“By increasing the use of green steel, we are making a
significant contribution to the sustainability of the railway industry. At the
same time, this strengthens our competitiveness and resilience and consolidates
our pioneering role as a provider of sustainable mobility solutions," says
Andreas Mehlhorn, Head of Sustainability at Siemens Mobility.
The premium products in the Greentec Steel Edition are
produced at the voestalpine site in Linz using a CO₂-optimized
production route and generate up to 70 percent less emissions than conventional
steel. Siemens Mobility already uses CO₂-reduced steel in bogies,
locomotives, and passenger coaches and plans to gradually increase its share.
With this agreement, Siemens Mobility is consistently
pursuing its sustainability strategy. By the end of fiscal 2030, the company
intends to achieve a 90 percent reduction in CO₂e emissions in its own operations
and to reach net-zero greenhouse gas emissions across the value chain by fiscal
2050. The use of CO₂-reduced steel significantly contributes to achieving
these goals and makes rail, as the most environmentally friendly mode of
transport, even more sustainable.
In mid-September, voestalpine presented Siemens Mobility with
the certificate for the declaration of greenhouse gas (GHG) emissions for the
quantities supplied to date. This ensures full transparency and traceability
along the supply chain.
