• Google will acquire environmental attributes tied to as much as 91,000 metric tons of Stegra steel produced during the plant’s first year.
• Stegra expects its hydrogen-based production process to cut emissions by up to 95% compared with conventional blast furnaces.
• The agreement could help Google reduce embodied carbon emissions from data centre infrastructure by up to 40%.

Google targets construction emissions

Google is backing Stegra’s planned green steel plant in northern Sweden, seeking to accelerate commercial demand for one of the industrial technologies considered critical to global decarbonisation.

The technology company will receive environmental attribute certificates, or EACs, linked to a portion of Stegra’s initial steel production. The agreement covers up to 91,000 metric tons during the plant’s first year of operation.

Stegra is developing what the companies describe as the world’s first large-scale, green hydrogen-based plant designed to produce near-zero emissions steel. Its output is intended to meet the International Energy Agency’s definition of near-zero emissions steel production.

For Google, the transaction addresses a growing climate challenge: emissions embedded in the materials used to build data centres. Demand for digital infrastructure is rising rapidly, driven in part by artificial intelligence and cloud computing. That growth is placing greater scrutiny on the carbon footprint of concrete and steel before facilities begin operating.

Google estimates that using lower-carbon construction materials could reduce embodied emissions from its data centre infrastructure by up to 40%.

Replacing coal with renewable hydrogen

Traditional blast furnaces use coal to convert iron ore into iron, creating substantial carbon dioxide emissions. Steel production is among the hardest industrial activities to decarbonise because of its high heat requirements and dependence on carbon-intensive processes.

Stegra’s Boden plant will instead use renewable electricity to produce green hydrogen. That hydrogen will react with iron ore, replacing coal during the ironmaking process.

The company estimates that this approach can reduce emissions by up to 95% compared with conventional blast furnace production. Achieving that reduction at scale would carry significance well beyond Sweden. Steel remains central to buildings, transport networks, energy systems and industrial equipment.

Still, early green steel facilities face high capital costs, technology risk and uncertain customer demand. Large corporate purchase commitments can improve revenue visibility and help developers secure financing.

Certificates create an early market

Google will not necessarily receive all the physical steel covered by the agreement. Instead, it will acquire the associated environmental attributes through certificates.

EACs allow buyers to support lower-emissions production and claim the environmental benefits associated with a defined volume of material. Their use is intended to build demand while physical supply chains and procurement systems mature.

The model could give steelmakers a financial incentive to invest in cleaner production. It may also help buyers address emissions that sit outside their direct operations, including those generated by construction suppliers.

However, certificate-based markets require credible accounting and clear ownership rules. Companies must demonstrate that environmental benefits are not counted more than once. They also need transparent baselines for comparing near-zero emissions materials with conventional alternatives.

The IEA definition provides one benchmark, but buyers and investors will continue to examine production data, electricity sources and certificate integrity.

Implications for executives and investors

The agreement shows how procurement can become a climate finance instrument. Long-term demand from large buyers can support industrial projects that might otherwise struggle to compete with established, carbon-intensive facilities.

Google is also working with initiatives including the Sustainable Steel Buyers Platform to expand the market for lower-emissions building materials. In 2025, the company integrated low-carbon concrete, steel or both into more than 20 construction projects.

For executives, the deal highlights the need to include embodied carbon in capital planning, supplier engagement and climate governance. Investors will also need to assess whether corporate procurement commitments create dependable revenue for emerging industrial technologies.

European policy will remain central. Carbon pricing, renewable power availability and standards for low-emissions materials will shape whether green steel becomes commercially competitive.

If Stegra delivers at the promised scale, Boden could provide a template for cleaner heavy industry. Its wider impact will depend on rigorous certification, stable policy and enough buyers willing to pay for industrial decarbonisation.
