Stainless steel – a sustainable choice of materials

Durable, robust and low-maintenance

Stainless steel boasts resilience and versatility – whether it is used for façades, containers, building structures or industrial applications. With the right selection of materials in a suitable application environment, stainless steel offers virtually maintenance-free properties for decades to come.

Lightweight, efficient and resource-saving

If low weight is to be combined with high load-bearing capacity, stainless steel is a sustainable solution. In the mobility and transport sectors in particular, every kilogram of material saved contributes to a reduction in energy consumption and resource requirements.

Low life cycle costs and carbon footprint

Minimal maintenance effort leads to low follow-up costs over the entire life cycle. At the same time, stainless steel supports a low-carbon value chain – making a decisive contribution to achieving company-wide sustainability goals.

Transparent origin and certified environmental standards

Accessible environmental data and certifications enable transparent traceability along the supply chain. Thus Scope 3 emissions, for example, can be accurately tracked – an important aspect for companies in energy-intensive industries.

Welcome to industrial evolution

For a decade, companies had to choose between stainless steel and sustainability. This has now come to an end: Outokumpu Circle Green® offers 100% stainless steel with only 7% of the regular carbon footprint.

"If all the stainless steel worldwide were produced to this standard, global CO₂ emissions could be reduced by up to 364 million tonnes per year, which would make a significant contribution to decarbonising the industry."
