Google Stegra green steel support will take the form of environmental attribute certificates tied to as much as 91,000 metric tons of output from Stegra’s first production year. Google announced the agreement on September 17, and Swedish public broadcaster SVT independently reported the same volume.
The important distinction is between buying a physical material and buying the verified environmental attributes attached to production.
What the Google Stegra green steel agreement covers
Stegra is building the plant in Boden, northern Sweden. Its process is designed to use renewable electricity to make hydrogen, then use that hydrogen to convert iron ore into iron. Traditional blast-furnace steelmaking relies heavily on coal. Stegra estimates its approach can cut emissions by as much as 95% against that conventional route.
Google says the output is intended to meet the International Energy Agency’s definition of near-zero-emissions steel. The agreement covers environmental attribute certificates, commonly called EACs, from a portion of first-year production. An EAC records the environmental benefit associated with a unit of material, allowing a buyer to support early production and account for the attribute under the relevant contractual rules.
That structure matters because the announcement does not say 91,000 tonnes of steel will be delivered to Google construction sites. It says Google will receive the certificates connected to up to that amount. Buyers should therefore read the figure as a demand and financing signal rather than a disclosed physical procurement schedule.
Why Google is buying the attributes
Steel and concrete account for a significant share of construction emissions before a building begins operating. Google estimates that using lower-carbon materials can reduce embodied carbon in data-center infrastructure by up to 40%. The company says it used low-carbon concrete, steel or both in more than 20 construction projects during 2025.
For a first-of-a-kind industrial plant, committed buyers can be as important as technical performance. They demonstrate demand and may help a producer finance scale-up. The commercial test will be whether Stegra starts production as planned, verifies the emissions intensity, and delivers certificates under a transparent accounting method without double counting.
Facts at a glance
| Item | Detail |
|---|---|
| Certificate volume | Up to 91,000 metric tons of first-year production |
| Plant location | Boden, Sweden |
| Process | Renewable electricity and green hydrogen replace coal in ironmaking |
| Claimed emissions cut | Up to 95% versus conventional blast-furnace production |
What this means
The Google Stegra green steel deal gives an emerging industrial process a named corporate buyer for its environmental value. It does not eliminate delivery, verification or accounting risk. The next meaningful milestones are commissioning, independently measured emissions intensity and evidence that each certificate is uniquely assigned.

FAQ
Is Google buying 91,000 tonnes of physical steel?
The announcement specifies environmental attribute certificates linked to up to 91,000 tonnes, not a physical delivery commitment for the full volume.
Where is Stegra’s plant?
The large-scale plant is being built in Boden in northern Sweden.
Why does the process use hydrogen?
Hydrogen can replace coal in the ironmaking step, reducing a major source of steel-production emissions when the hydrogen is made with renewable electricity.
