Sep 25, 2025 | Posted by Abdul-Rahman Oladimeji

Microsoft has signed a deal with green steel company Stegra for the supply of low-carbon steel for use within its data centers.  The agreement will see Stegra deliver green steel, which it claims is up to 95 percent less carbon-intensive than conventional steel, to Microsoft's data center equipment suppliers.

"Integrating near-zero emission steel into our data center construction is a critical advancement in reducing embodied carbon at scale," says Jennifer Weitzel, corporate vice president of engineering, construction, and procurement at Microsoft. "This collaboration with Stegra enables us to decarbonize our infrastructure, while maintaining the performance and reliability standards required for hyperscale environments."


"Through the environmental attribute certificates, the green value can be sold to Microsoft, a player of a unique size that can really help move the needle in the right direction. It's impressive that Microsoft has chosen to team up with Stegra and together put something completely new on the steel market that will incentivize bigger volumes and more locations for steel production with close to zero emissions," said Stegra CEO, Henrik Henriksson.
