ArcelorMittal supports JLR's Cornerstone circular vehicle project with XCarb^® steel

JLR (Jaguar Land Rover) has unveiled its new Cornerstone concept demonstrator, developed with more than 40 partners to showcase circular solutions for future vehicles. The project features 49 components designed to increase recycled content, improve repairability and reduce CO₂ emissions. ArcelorMittal is proud to contribute to JLR's initiative with XCarb^® recycled and renewably produced steel, used in key components including the side impact beam and tunnel topper.

These components demonstrate how collaboration across the automotive value chain - in this case with JLR, ArcelorMittal and Gestamp - can accelerate the adoption of scalable solutions for next-generation vehicles.

The side impact beam and tunnel topper components achieve:

• Up to 88% circular content
• CO₂e emissions reduced by 59% compared with conventional solutions

The announcement comes shortly after JLR presented ArcelorMittal with a Certificate of Recognition in the "Visionary" category at the company's Global Supplier Conference in June 2026. The certificate acknowledged ArcelorMittal's contribution to material optimisation, innovative steel solutions and support for JLR's net-zero ambitions, further highlighting the strength of the partnership between the two companies.

The Cornerstone project is a great example of how ArcelorMittal is helping automotive customers advance decarbonisation through innovative steel solutions.

To support customers in reducing embedded emissions, ArcelorMittal has developed the XCarb^® recycled and renewably produced steel portfolio.

This offer combines high levels of recycled scrap with steel production powered by renewable electricity. A key example is ArcelorMittal’s electric arc furnace (EAF) facility in Sestao, Spain. Operational since 2022, the plant produces flat steel using scrap as the primary raw material and electricity sourced from renewable energy.

The facility has an annual production capacity of approximately 1.6 million tonnes and demonstrates that low-CO₂ steel production can already be achieved at industrial scale.

Grades within the XCarb^® recycled and renewably produced portfolio are backed by a guaranteed minimum recycled content of at least 75 percent and production using 100 percent renewable electricity. Depending on grade and scrap availability, even higher recycled content levels may be achieved.

ArcelorMittal is also strengthening this pathway for the future. Planned investments such as the electric arc furnace project in Dunkirk represent a major next step in expanding low-CO₂ flat steel capacity in Europe.
