Microsoft and Stegra Partner for Near-Zero Emission Steel in Data Centers

September 23, 2025
Stegra has announced a partnership with Microsoft to supply near-zero emission steel for Microsoft's data centers, as stated in a press release. This agreement includes the purchase of environmental attribute certificates to promote green steel demand.

Microsoft Corporation has entered into a partnership with Stegra to supply near-zero emission steel for its data centers, announced in a press release. This collaboration includes two agreements: one for the physical supply of green steel and another for the purchase of environmental attribute certificates (EACs) from Stegra's facility in Boden, Sweden.

The steel supplied by Stegra will have up to 95% lower emissions compared to conventional steelmaking. This initiative aligns with Microsoft's goal to reduce embodied carbon in its data center construction, supporting its ambition to become carbon negative by 2030. The EACs allow Microsoft to claim the use of low-emission steel in its operations, even when physical delivery isn't feasible.

Stegra's CEO, Henrik Henriksson, emphasized the importance of unconventional partnerships in driving sustainable change, while Microsoft's Corporate Vice President, Jennifer Weitzel, highlighted the critical advancement in reducing embodied carbon at scale through this collaboration. The agreements aim to signal demand for low-carbon materials and accelerate global production of green steel.
