Low-carbon steel ‒ our contribution to the decarbonization of industry
Protection of the environment and the climate, conservation of natural resources and prudent use of energy constitute key issues for Salzgitter AG. For us, protecting the climate and the environment goes beyond the observance of statutory regulations, as it plays a decisive role in shaping our corporate behavior – now and in the future. For that reason, we are playing a pioneering role in the decarbonization of the steel industry with our SALCOS® project that is without compare throughout Europe.
Climate protection
With conventional steel production, large quantities of greenhouse gases are emitted in conjunction with the manufacturing process. Therefore, showing tremendous dedication, we are driving the transition to steel production with a CO2 reduction of up to 95% compared to current methods forward, to a greater extent and scope than any other producer worldwide, and are currently firmly in the midst of the transformation.
Validated science-based climate objectives
Our science based climate objectives, which were validated by the Science Based Targets Initiative (SBTi) in 2024, are an expression of our commitment and ambition. Consequently, we are on the required climate course to adhere to the 1.5°C objective set by the Paris Climate Agreement. A progress assessment is already scheduled for 2028. With the first step of our SALCOS® program (Salzgitter Low CO2 Steelmaking), we currently find ourselves in the midst of the transformation of our primary steel manufacturing processes, and are thereby already laying the foundations for the achievement of future objectives today.

Energy efficiency and renewable energy
The economical and efficient use of energy is a key driver of sustainable business practices at Salzgitter AG. To this end, we continuously identify and tap into energy-saving opportunities and make targeted use of the technological innovation potential of our Group companies.
The systematic optimisation of our energy use, combined with the consistent increase in the procurement of external electricity from renewable sources, underlines our climate protection ambitions. In 2025, we were able to significantly increase the share of renewable external electricity to 64%.
Circular economy and resource efficiency
Steel is durable and there are almost no limits to the number of times it can be reused. Closed loops therefore form a key element of our Group strategy. We are creating the conditions for tomorrow’s circular economy by optimizing production processes but also by means of new strategic partnerships.
Expanding scrap recycling
One of Salzgitter AG’s major strategic goals is to expand our market share of recycled scrap metal. Every ton of scrap used reduces the quantity of iron ore and other primary raw materials required in steel production.
