ArcelorMittal faces uncertainty over the pricing of steel produced at its upcoming low-carbon plant in Dunkirk, France, highlighting broader challenges in the European steel industry’s transition to greener production. The €1.3 billion facility, set to begin operations in 2029, will feature an electric-arc furnace designed to reduce greenhouse gas emissions per tonne of steel by approximately two-thirds compared to traditional blast furnaces. However, the technology comes with significantly higher costs.

Bruno Ribo, chief executive of ArcelorMittal France, stated that the company currently lacks clear visibility on how rapidly demand for green steel will grow or whether customers will be willing to pay a premium for it. He noted that while the company has made pricing assumptions, particularly regarding European car manufacturers who are among the largest steel consumers in the region, there remains a high level of uncertainty.

Green steel production generally carries a cost premium of 20 to 30 percent due to substantial upfront investments and elevated electricity consumption. Additionally, decarbonized steelmaking relies on a higher proportion of recycled steel, which poses technical challenges because of the variability in scrap metal composition, according to Ribo.

The decision to proceed with the Dunkirk project followed sustained lobbying by ArcelorMittal and steel industry groups for increased protection from cheaper imports, which have impacted European producers amid weakening demand. Data from Eurofer, the association representing the European steel industry, shows that steel imports from outside Europe increased to 26 percent of regional supply in 2025 from 20 percent in 2016, while EU production declined from 69.3 million tonnes to about 57.3 million tonnes in the same period. Axel Eggert, Eurofer’s director-general, described the ongoing influx of imports as abnormal, especially given their persistence despite a downturn in demand.

In response to these pressures, the European Union implemented measures earlier this year to mitigate the impact of imports and support domestic producers. These include the carbon border adjustment mechanism, which imposes equivalent carbon costs on imports, and new trade quotas introduced in July that reduced duty-free steel imports by 47 percent compared to 2024 levels. Additionally, the EU has eased certain obligations under its emissions trading system by delaying the phaseout of free carbon permits by four years.

ArcelorMittal has secured electricity for the Dunkirk plant from the nearby Gravelines nuclear power station with guaranteed pricing through an agreement with French state energy company EDF, alongside subsidies from a French energy certificate program. Despite improved conditions boosting the share prices of major European steelmakers—including Thyssenkrupp, Salzgitter, and ArcelorMittal—decarbonization efforts remain cautious.

In Germany, Thyssenkrupp has paused talks with India’s Jindal Steel, which had planned a €2 billion investment into green steel technologies supported by government subsidies. Thyssenkrupp continues to face difficulties finding buyers willing to assume its steel unit’s pension liabilities, estimated at around €2.7 billion, with previous negotiations having stalled. Unions have proposed listing the steel division publicly to attract investment.

Several other European producers have delayed or scaled back decarbonization initiatives due to concerns over energy security and the competitiveness of higher-cost green steel. Germany’s Salzgitter recently confirmed plans for a new electric-arc furnace supported by €200 million in government funding, while Sweden’s SSAB has postponed projects due to permitting and electricity grid challenges. Czech steelmaker Třinecké Železárny has also deferred similar plans.

Analysts note that while such projects were originally framed as part of an ambitious industry transition, the absence of promised subsidies, clear regulatory frameworks, and an established hydrogen infrastructure has led many firms to scale back expectations. ArcelorMittal’s Dunkirk facility itself is a reduced version of an initial €1.8 billion proposal that included multiple electric-arc furnaces and a direct-reduction plant. The company has also discontinued a comparable German project.

Former ArcelorMittal Europe chief executive Geert Van Poelvoorde emphasized that the Dunkirk electric-arc furnace will only replace one blast furnace at the site, limiting financial exposure. He added that France remains among the few European countries where the economics for green steel production are viable, citing challenges to obtaining competitively priced electricity in Germany and the lack of reliable backup power for nuclear and renewable energy in neighboring countries.

The tightened EU import quotas are projected to reduce steel imports by about 10 million tonnes annually. However, analysts caution that if imports remain elevated or demand fails to increase, additional volume entering an already balanced market could further depress steel prices. Overall, while market sentiment shows some improvement, the steel industry’s path to decarbonization continues to face significant economic, technological, and geopolitical hurdles.
