Leading the low-carbon steel revolution
March 16, 2026

The UK has a proud history in steelmaking, but the industry today is faced with unprecedented challenges. 

From energy prices and tariffs through to global competition and uncertain market conditions, these changes are creating an opportunity – the potential for UK steelmaking to transform itself into a global leader in low-carbon steel production. 

Steel is one of the most commonly used materials in construction, underpinning almost every building project, from landmark infrastructure developments such as Hinckley Point and HS2, to the building of new homes. As this sector faces increasing pressures to reduce embodied carbon, the production techniques behind essential materials such as steel comes into greater focus. 

For the UK steel industry, producing steel responsibly means transitioning from traditionally carbon-intensive practices towards cleaner production techniques. In practice, this means: 

  • Replacing blast furnaces with Electric Arc Furnaces (EAF)
  • Using steel scrap to create new steel products
  • Transitioning towards renewable energy

The UK steel industry is pioneering this transition, with 7 Steel UK already operating EAF production and other producers following suit by adopting EAF technology in the coming years. 

The steel industry today

It’s no surprise that the UK steel industry is struggling. The global overcapacity of steel has kept competition high and prices low; volatile energy costs within the UK have increased the cost of production domestically; and a long-term dependence on imported steel are all factors that have impacted the UK steel industry. 

On the other hand, growing expectations around sustainability, traceability and embodied carbon, particularly across the construction industry, are leading to a renewal of steel production in the UK – albeit production which is more suited to a sustainable future. 

Continued investment in major UK steelworks will see new Electric Arc Furnaces in full operation in the coming years. Already, 7 Steel UK has long proved the potential of EAF steel production through its Cardiff facility. Every year over 1 million tons of steel scrap is recycled at the site and transformed into new steel which is largely supplied to domestic construction projects. 

Of course, for our steel industry to be sustainable for the long-term, targeted support is essential. The evolving steel strategy for the UK must: 

  • Prioritise domestic production over imports 
  • Support the transition to low-carbon production 
  • Protect the sector from the impact of global overcapacity 

    Why the future of steel is low carbon

    When it comes to producing low-carbon steel, there are several crucial differences compared to traditional processes. 

    Recycling steel scrap is an essential part of the process, ensuring high-quality feedstock that can be transformed into new steel. The use of Electric Arc Furnaces, rather than blast furnace production, uses electricity rather than coal which significantly reduces the carbon intensity of steel production. As the grid continues to decarbonise in the coming years, the benefits of low-carbon steel production will continue to grow. 

    7 Steel UK’s production model is built around these principles. With an Electric Arc Furnace at the heart of production in Cardiff and a clear commitment to source steel scrap within the UK, operations are prioritising environmental requirements while boosting domestic industrial resilience.  

    In practice, this set-up ensures that steel scrap is recovered, processed and transformed in the UK, keeping vital resources in circulation, reducing reliance on imported materials and volatile global supply chains, and elevating the transparency and traceability of materials used in UK construction projects. 

    These capabilities don’t come without significant investment in UK infrastructure. As well as operating an EAF as the central point of manufacturing operations, 7 Steel UK also has an established nationwide recycling capability, allowing for steel scrap to be retained, sorted and processed domestically. 

    In contrast, a significant proportion of steel imported into the UK continues to be produced through blast furnace techniques, embedding high carbon emissions before the material even reaches UK ports. While this steel may still meet specification requirements, its high carbon footprint, lack of traceability and long lead times present challenges for British projects that must comply with ever-tighter sustainability and reporting frameworks. 

    An essential domestic industry 

    With EAF-made steel already being produced in the UK, the case for strengthening the domestic steel industry moves beyond heritage and towards resilience. 

    Every year, millions of tonnes of steel are used across the UK economy. A large proportion of this is used in construction projects and major infrastructure developments – from transport through to renewable energy. Without a domestic steelmaking capability, projects are left open to the global markets which can directly impact levels of certainty, quality and compliance. 

    Low-carbon steelmaking strengthens our national resilience by aligning industrial capability with climate goals, supporting regional economies and strengthening supply chains. Domestic production also keeps the UK in control, ensuring efforts to decarbonise construction and infrastructure are not reliant on overseas production changes. 

    Additionally, this approach positions UK industry to respond to future needs, whether they’re driven by the growth of offshore wind, large-scale housing projects or new infrastructure. 

    Leading the low-carbon steel revolution

    The move towards low-carbon steel is already beginning to define the next chapter of the UK’s steel industry, with greater levels of investment in EAF production in the works and producers such as 7 Steel UK demonstrating its potential. However, for the UK to maximise its position as a leader in low-carbon steel production, alignment between government policy, industry support and market demand is essential. 

    By ensuring targeted support for the steel industry, particularly producers of low-carbon steel, the UK can realise environmental and economic gains. Alongside this, a strong domestic steelmaking industry can directly support critical sectors such as construction to prioritise local material specification and elevate decarbonisation commitments. 

    With steel producers already committing to a more sustainable future, the next step is for industry and policy to align and reinforce the potential of our domestic steelmaking capability, making it possible for the UK to lead the low-carbon steel revolution.
