Emission Efficacy & Energetic Equity, The Electric Arc Furnace Advantage

Electric arc furnace steelmaking stands at the forefront of sustainable steel production in Europe. By melting scrap steel or direct reduced iron using electrical energy, these furnaces emit far less carbon dioxide compared to traditional blast furnace-basic oxygen furnace operations. As of 2025, approximately 45% of European steel is produced via this route. Governments and companies alike recognize electric arc steel’s potential to expedite the continent’s march toward net-zero emissions by 2050, though broader awareness and support have yet to fully align.

Carbon Contrast & Clean Cutoffs, Benchmarking Low-Carbon Heights

Currently, blast furnace-basic oxygen furnace methods emit roughly 2.0 to 2.2 metric tons of carbon dioxide per metric ton of steel, while electric arc furnaces emit significantly less. Industry leaders like Alexandra Gordienko note that ongoing improvements in energy sourcing and production processes may allow electric arc products to qualify as “green steel.” Fastmarkets defines green long steel as having Scope 1, Scope 2, and Scope 3 emissions under 500 kilograms of CO₂ per metric ton, but this threshold is expected to tighten toward 300 kilograms as grids and processes improve.

Energy Intensity & Efficiency Imbalance, Electric Arcs Outconsume but Outperform Emissions

Despite lower carbon emissions, electric arc steel production consumes far more electrical energy,  approximately 0.45 MWh per metric ton compared to just 0.05 MWh for blast furnace-basic oxygen furnace operations. This energy inefficiency is due to the heat-intensive nature of melting steel electrically. While the carbon footprint per unit is lower, the electrical demand creates cost and stability challenges. Consumers and policymakers must balance emissions benefits with energy requirements to determine the true sustainability of this method.

Electricity Economics & Exorbitant Expense, Price Volatility Pressing Producers

Europe’s electricity markets have seen wild fluctuations, with wholesale prices swinging from €20–30 to above €200 per MWh since 2022. These swings translate into retail cost volatility, adding as much as €70 per metric ton of steel in production costs, which producers cannot easily pass on to customers. Compared to steel operations in the U.S. or China paying around €30–50 per MWh, European producers face steep energy premiums. These pricing obstacles risk undermining the competitiveness of electric arc steel despite its environmental advantages.

Public Purse & Policy Parity, Disparate Funding Doors for EAF Producers

Despite more than €14 billion in public support allocated to green steel initiatives by the end of 2024, funding has predominantly targeted blast furnace-basic oxygen furnace projects. Electric arc companies have seen minimal funding, especially for existing plants. Celsa’s Gordienko urges policy mechanisms such as renewable power tariffs indexed to emissions trading costs. He advocates for equal access to energy-price stability, which would help electric arc producers maintain fair competition and decarbonization momentum.

Scrap Scarcity & Supply Shortfalls, Feedstock Friction Threatening Growth

Electric arc furnaces rely heavily on steel scrap, yet Europe’s domestic market generates around 100 million metric tons annually, with 20% exported at lower prices. This dynamic limits scrap availability and drives up domestic prices by €20–40 per metric ton of steel produced. Additionally, producing low-copper, high-quality "premium scrap" for green steel requires infrastructure investments, which have lagged. Without secure scrap supply, new electric arc capacity expected by 2030 could face limiting bottlenecks.

Directive Deficiencies & Decarbonization Demands, Policy Must Push Power Progress

To scale clean steel, policy frameworks must bridge energy, emissions, and supply chain gaps. Carbon pricing, renewable energy incentives, and scrap retention policies can level the playing field. Targeted support for electricity rates and export controls could bolster electric arc producers. Collaboration among governments, industry, and finance is crucial for fostering a competitive, climate-aligned transition in steelmaking.

Competitive Cost & Carbon Confluence, A Crucial Crossroads for Green Steel

Electric arc steel embodies Europe’s ambition for greener industry, yet uncertainty in energy pricing and insufficient support threaten its viability. To capitalize on its low-carbon potential, policymakers must synchronise emissions goals with electricity economics and scrap availability. A coherent approach will ensure electric arc furnaces not only reduce carbon, but also sustain industrial scale and competitiveness in a rapidly changing global market.

Key Takeaways:

• Electric arc furnaces emit far less CO₂ but consume nearly ten times more electricity than traditional steelmaking methods.

• Price volatility in European power markets adds up to €70 per metric ton in production costs for electric arc steel.

• Scrap constraints and funding gaps for existing electric arc facilities may limit the green steel transition without targeted policy fixes.
