Green steel is no longer a concept. It is entering commercial production. SSAB delivered the world's first fossil-free steel to Volvo in 2021 and is converting its Oxelosund plant to electric arc furnace (EAF) by 2025. Stegra (formerly H2 Green Steel) has pre-sold offtake agreements covering over 1.5 million tonnes per year. ArcelorMittal offers XCarb green steel certificates verified by DNV. The market exists, but it is small, fragmented, and confusing.
Premium ranges quoted in the market span 15% to 40% above conventional steel. The reality is more nuanced. Some products command EUR 350 per tonne above hot-rolled coil on long-term contracts. Others trade at just EUR 50 on the spot market. Some carry no premium at all outside Europe. For procurement professionals, the gap between marketing and reality is the single biggest risk. This article provides a framework for evaluating green steel claims, understanding certification schemes, and making purchasing decisions that deliver real emissions reductions at defensible cost.
The Premium Landscape: What You Are Actually Paying For
Green steel premiums exist, but they vary wildly by region, product type, and contract structure. Understanding these variables is the first step in separating real value from inflated claims.
In Europe, Fastmarkets tracks a weekly green flat steel premium differential against the hot-rolled coil index. That assessment stood at EUR 100 to 170 per tonne in January 2026, having peaked around EUR 200 in late 2023 before falling to EUR 50-75 per tonne in late 2024 as European steel demand weakened. Through 2025, the premium stabilised in the EUR 120 to 180 per tonne range, suggesting that European buyers with long-term sustainability commitments are prepared to sustain a premium of that order for certified flat steel. In long-term bilateral contracts with automotive customers, mills offering carbon-certified HRC with emissions below one tonne of CO2 per tonne have quoted premiums as high as EUR 200 to 350 per tonne.
Outside Europe, the picture is starkly different. In China, buyer willingness to pay is capped at approximately USD 20 per tonne against a production cost premium near USD 140. That gap makes commercial green steel production in China economically irrational without regulatory compulsion. In the United States, Fastmarkets' green steel HRC differential has sat at zero since its launch in May 2024. The reason is structural: approximately 70% of US steel production already uses the EAF route, which is inherently lower-carbon. Domestic buyers see no reason to pay extra for a marginal improvement they already get by default.
This regional divergence has direct implications for procurement strategy. A CPO sourcing steel in Europe faces a real, measurable premium. A CPO sourcing in North America or Asia faces a market where green premiums are, for practical purposes, nonexistent. The premium is a European phenomenon, and even there it is concentrated in flat products for the automotive sector.
The Volume Problem: Tiny Market, Huge Claims
The most important fact about green steel procurement is how small the certified market actually is. Global crude steel production reached approximately 1,886 million tonnes in 2024, according to the World Steel Association. Against that, the volume of steel that is genuinely certified to an independently verified carbon intensity threshold, and on which a premium has actually been paid, is estimated at well under 5 million tonnes. That is roughly 0.25% of world output.
Commercial market research reports quote wildly inconsistent figures for the size of the green steel market, ranging from USD 4 billion to over USD 700 billion for 2024. These figures are almost useless for procurement decisions. They define "green steel" so broadly, often including all EAF production regardless of carbon intensity or certification, that they bear no relationship to the market in which a verified price premium is actually transacted. A procurement officer relying on these headline numbers will overestimate available supply and underestimate the competition to access it.
Automotive Dominates. Everything Else Lags.
Of all the industries that buy steel, only one is currently paying a meaningful green premium at any significant volume: automotive. The reasons are specific to that sector. Car manufacturers face stringent Scope 3 emissions reporting obligations. Steel is a small share of vehicle cost but a significant share of its lifetime carbon footprint, particularly for electric vehicles where tailpipe emissions are eliminated. A premium-segment manufacturer like Mercedes-Benz or Porsche can absorb EUR 150 to 350 per tonne of green steel without meaningfully affecting its vehicle pricing.
The math is revealing. Steel accounts for roughly 830 kg of a typical passenger car. A green premium of EUR 200 per tonne adds approximately EUR 165 to the manufacturing cost of a vehicle. That is less than 1% of the average transaction price for a premium-brand car. No other major steel-using sector shares this combination of high value-added end product, consumer-facing sustainability narrative, and regulatory Scope 3 pressure.
Every other sector lags far behind. Construction, which consumes roughly 49% of global finished steel through long products like rebar, sections, and wire rod, has essentially no functioning green premium market. Contractors buy to specification at the lowest price. Offshore wind and energy infrastructure show emerging willingness but volumes remain tiny. White goods and industrial machinery show low to moderate interest, constrained by tight product margins. The consequence is that the majority of certified green flat steel currently traded flows to a small number of premium automotive buyers through private bilateral contracts at undisclosed prices.
"The premium is real in Europe but ranges very widely — from negligible on the spot market to EUR 350 per tonne on certified long-term contracts — making headline figures misleading without context."

The single biggest structural obstacle in green steel procurement is the absence of a common, independently verified definition of what green steel actually is. Without one, buyers cannot confidently pay a premium, producers cannot reliably capture one, and the premium itself risks being undermined by greenwashing.
Two competing certification frameworks currently dominate the debate. ResponsibleSteel, now in Version 2.1.1 as of October 2024, offers site-level certification based on broad ESG performance with a sliding scale adjusted by scrap input. It evaluates performance across environmental, social, and governance topics throughout the steel value chain, with third-party audits from accredited bodies like DNV. Sites can achieve Core Site Certification and then progress to Certified Steel status, which adds requirements for responsible sourcing of input materials and specific decarbonization thresholds.
The Green Steel Certification Council (GSCC) takes a different approach. It sets product-level fixed carbon intensity thresholds aligned with science-based 1.5-degree targets and requires third-party verified emissions reporting. These are not simply different standards. They reflect fundamentally different views about what should count as green. A site that performs well on ESG criteria but continues to operate blast furnaces might qualify under ResponsibleSteel but fail the GSCC threshold. The Metalshub Green Steel Conference in May 2025 concluded bluntly: there is still no agreed definition of green steel.
Mass Balancing: The Biggest Red Flag for Buyers
Mass balance accounting is the most controversial practice in green steel procurement today. Under this approach, a producer blends conventional and low-carbon production in a shared process but allocates all the green attributes, on paper, to a subset of customer orders. The physical steel delivered may be identical to conventional steel, but the buyer receives a certificate stating that their tonnes are "green." Total certified green output can therefore exceed the plant's actual low-carbon production.
This approach is deeply contested. Some buyers accept it as a legitimate accounting method during a transition period. Others reject it as greenwashing. The EU's CBAM does not permit mass balance accounting. Importers must demonstrate actual facility-level emissions data. A product certified "green" under mass balance may still attract full CBAM costs. For procurement professionals, the rule is straightforward: if a supplier cannot provide facility-level emissions data verified by a third-party auditor for the specific tonnes you are buying, the green claim should be treated as unverified.
Five Questions Every CPO Must Ask Before Buying Green Steel
- What is the certified carbon intensity? Demand the actual cradle-to-gate CO2 per tonne figure, verified by a third-party auditor, for your specific order.
- Which certification scheme applies? ResponsibleSteel, GSCC, or an EPD? Each uses different thresholds. Know which one your order qualifies under.
- Is mass balance being used? If yes, the physical steel may be identical to conventional. Understand what you are actually paying for.
- What is the premium baseline? Is the premium quoted against the published HRC index for that week, or against a negotiated base price? These can differ by hundreds of euros.
- Does the supplier have physical production capacity? Many "green steel" offerings are certificates or book-and-claim arrangements backed by limited actual low-carbon output. Verify the production facility.
The Supply Pipeline: Real Projects, Real Delays
The most credible supply anchor for the certified green steel market is project-level data. Stegra in Sweden has pre-sold over 1.5 million tonnes per year of its planned 2.5 million tonnes initial output, with offtake agreements signed with Mercedes-Benz, Porsche, Scania, Volvo Group, and ZF. The plant targets 2.5 million tonnes by 2028 and 5 million tonnes by 2030. ArcelorMittal's new EAF at Dunkirk targets approximately 2 million tonnes per year of low-carbon flat steel. SSAB's HYBRIT process is moving toward industrial scale demonstration by 2026, with the company signing delivery agreements with Rheinmetall, Vattenfall, and GE Vernova.
But these projects face headwinds. Across Europe, major decarbonisation investments have been postponed, suspended, or cancelled in a pattern that is systemic. ArcelorMittal cancelled DRI and EAF investments at two German assets in June 2025. Thyssenkrupp suspended its tender for green hydrogen supply to its planned Duisburg DRI plant in March 2025. SSAB postponed commissioning of its new Lulea plant by twelve months due to power grid delays. Salzgitter pushed further stages of its Salcos project to 2028-2029. Common causes run through these deferrals: elevated electricity costs, hydrogen infrastructure immaturity, slow grid permitting, and weak near-term steel demand.
"The gap between these volumes and what the steel industry's decarbonisation requires is not a reason for pessimism. It is a reason for policy clarity."

SSAB offers two distinct products. SSAB Zero is produced using recycled steel and fossil-free electricity in EAFs, with near-zero emissions from the steelmaking process itself. SSAB Fossil-free is produced using HYBRIT technology: hydrogen-reduced sponge iron that replaces coal and coke, with water as the by-product instead of CO2. The first commercial-scale HYBRIT steel was produced in 2021, and SSAB targets industrial-scale delivery by 2026. In January 2026, SSAB signed a letter of intent with Rheinmetall, marking the first defence sector adoption of fossil-free steel. In October 2025, SSAB agreed to supply 120 tonnes for the world's first fossil-free dam gate with Vattenfall.
ArcelorMittal's XCarb brand bundles three initiatives: XCarb steel certificates (certificate-based Scope 3 emission reductions from BF-BOF operations, verified by DNV), XCarb recycled and renewably produced steel (EAF steel using recycled scrap and 100% renewable electricity), and the XCarb innovation fund. The certificates allow customers to report equivalent Scope 3 reductions under the GHG Protocol, but they are not physical green steel. They are financial instruments tied to emission reduction projects at ArcelorMittal facilities.
Stegra (formerly H2 Green Steel) is building a fully integrated green steel plant in Boden, Sweden, using hydrogen-based DRI and EAF technology powered by renewable electricity. It has secured over EUR 6.5 billion in financing and offtake agreements for more than half its planned initial capacity. The company reports achieving a 20 to 30% premium over conventional steel on its seven-year take-or-pay contracts.
The key takeaway for procurement: these three suppliers represent the bulk of genuinely certified European green flat steel production. Available supply from credible, physically producing sources is extremely limited relative to demand. Any supplier claiming to offer green steel at scale without reference to one of these projects, or a comparable verified facility, warrants scrutiny.
What CBAM Means for Your Green Steel Procurement Strategy
The EU's Carbon Border Adjustment Mechanism is the most powerful structural driver of green steel procurement. The European Commission sets China's default embedded emissions value for HRC at 3.187 tonnes of CO2 per tonne of steel, against a typical EU EAF intensity below 0.5 tonnes. At current EU ETS carbon prices, this translates to a CBAM cost of approximately EUR 145 per tonne on Chinese HRC imports. In effect, CBAM imposes a mandatory carbon cost on high-emission imports that approximates the voluntary premium currently paid for certified green steel.
For importers, the choice becomes stark: demonstrate lower actual emissions and reduce CBAM liability, or pay a carbon surcharge that will make conventional high-emission imports progressively less competitive. This mechanism will convert the green premium from an optional extra into a structural cost of market access. CPOs who build CBAM scenarios into their 2027-2030 sourcing plans will have a significant advantage over those who treat green steel procurement as a voluntary CSR initiative.
Building a Green Steel Procurement Framework
An effective green steel procurement strategy rests on four pillars. First, establish a verified carbon threshold. Do not accept supplier claims without independent third-party certification from a recognized scheme like ResponsibleSteel or GSCC. Require facility-level emissions data, not corporate averages or mass balance certificates.
Second, understand the total cost impact in context. A EUR 200 per tonne premium on steel adds roughly EUR 165 to the cost of a passenger car, less than 1% of a premium vehicle price. For a construction project using 10,000 tonnes of rebar, a EUR 100 per tonne premium adds EUR 1 million to project cost, a significant but manageable increment. Calculate the premium impact against your specific bill of materials, not against industry averages.
Third, match contract structure to market reality. The spot market for green steel is thin and illiquid. Long-term offtake agreements with producers like Stegra or SSAB offer price certainty and supply security. Bilateral contracts with carbon intensity clauses offer flexibility. Spot purchases should carry a significant scepticism discount on green claims.
Fourth, plan for premium compression. As green steel supply scales and hydrogen costs fall, the premium will narrow. Producers who structured investment cases around EUR 200 per tonne premiums indefinitely will face margin pressure by 2035. Procurement frameworks should phase down premium tolerance over time, aligning with expected cost curves.
The Bottom Line
Green steel procurement in 2026 requires more diligence than most CPOs expect. The market is real but tiny, concentrated in European flat products for automotive buyers, and built on a fragmented certification landscape. Premiums are real but vary by an order of magnitude depending on contract structure, region, and certification scheme. The absence of a common definition of green steel is the single biggest obstacle to efficient procurement.
The regulatory direction is clear. CBAM, tightening Scope 3 reporting obligations, and emerging green public procurement mandates will convert voluntary demand into mandatory compliance over the next five to ten years. CPOs who build the capability to evaluate green steel claims today, who establish relationships with verified producers, and who integrate carbon cost scenarios into their sourcing models, will be positioned to capture supply at reasonable terms. Those who treat green steel as a marketing exercise risk paying inflated premiums for unverified claims, or worse, being locked out of the certified supply chain entirely as regulatory requirements tighten.
Procurement is the lever. Use it with precision.
Frequently Asked Questions
What is the actual green steel premium in 2026?
The premium ranges from approximately EUR 50 per tonne on the European spot market to EUR 350 per tonne on certified long-term contracts with automotive buyers. The Fastmarkets weekly assessment for European green flat steel stood at EUR 100-170 per tonne in January 2026. Outside Europe, the premium is negligible or zero.
Which certification scheme should I trust for green steel?
ResponsibleSteel provides site-level certification covering broad ESG criteria and has the broadest industry adoption. The Green Steel Certification Council (GSCC) uses stricter product-level carbon intensity thresholds aligned with 1.5-degree targets. Both have value, but they measure different things. Buyers should understand which scheme applies to their specific order and what threshold was met.
Is mass balance green steel the same as physically green steel?
No. Mass balance accounting allows a producer to sell green certificates for conventional steel by blending low-carbon and conventional production on paper. The physical steel delivered may be identical to conventional steel. EU CBAM does not recognize mass balance accounting. Buyers should request facility-level emissions data verified by a third party.
How will CBAM affect green steel pricing?
CBAM imposes a carbon cost on imports based on embedded emissions. At current EU ETS prices, Chinese HRC carries an estimated EUR 145 per tonne CBAM liability. This effectively creates a mandatory carbon premium that will make green steel more competitive relative to conventional imports.
Who are the main producers of certified green steel?
The three most significant producers are SSAB (SSAB Zero and SSAB Fossil-free via HYBRIT), Stegra (hydrogen-based DRI-EAF in Sweden), and ArcelorMittal (XCarb recycled and renewably produced EAF steel, plus XCarb certificates). Combined, these producers represent the bulk of genuinely certified European green flat steel production.
