ArcelorMittal Luxembourg headquarters takes shape with XCarb
The construction of ArcelorMittal’s new headquarters in Luxembourg is gathering pace, with the building in Luxembourg City acting as a showcase for the brand, Kallanish hears.
The steelmaker says the construction site is the largest in Luxembourg and the Greater Region. The group announced in June 2023 that the first steel beam on the 21-storey building had been installed.
Now standing at more than eight storeys high, the building is scheduled to be ready in 2027. The building is also meant as a showcase for Steligence, which ArcelorMittal calls its proprietary design philosophy, combining sustainability, innovation and flexibility in construction at scale, comprising steel, glass and green spaces.
The building’s exoskeleton is being built with its low-emission steel brand, XCarb, which is made in Luxembourg with 100% recycled steel in an EAF, using 100% renewable energy. The XCarb recycled and renewably produced steel is produced in Differdange and Belval and fabricated in the Steligence Fabrication Centre.

ArcelorMittal expands commitment to low-carbon steel with LESS membership across Europe
Global steel giant ArcelorMittal has announced that its subsidiaries in Belgium, France, Luxembourg, and Spain have joined the Low Emission Steel Standard (LESS), reinforcing the company’s leadership in producing low-carbon steel in Europe. ArcelorMittal Germany became a founding member of LESS in 2024.
What is LESS?
The Low Emission Steel Standard (LESS) is a voluntary initiative aimed at creating a credible and unified framework for labeling low-emission steel in the EU, and is already adopted by around 45 percent of European steelmakers. Although demand for low-carbon steel is increasing, most of the steel in Europe is still produced with conventional methods.
ArcelorMittal scales up XCarb® low-carbon steel
ArcelorMittal is currently Europe’s leading supplier of low-carbon steel through its XCarb® brand. In 2024, the company delivered 400,000 mt of XCarb® steel and expects that number to increase in 2025.
Policy support: EU’s Industrial Decarbonization Accelerator Act
The European Commission’s Steel and Metals Action Plan that was published in March this year has introduced mechanisms to support green steel markets. The upcoming Industrial Decarbonization Accelerator Act aims to stimulate demand for locally produced low carbon metals in public procurement and create lead markets to increase the use of low carbon steel in industries such as automotive and construction.
Challenges ahead: Insufficient policy and challenging market conditions
Despite its commitment, ArcelorMittal faces delays in its decarbonization projects due to insufficient policies and challenging market conditions. Current investments are focused on expanding electric arc furnace (EAF) capacity in Gijón and Sestao in Spain to increase XCarb® steel production.
ArcelorMittal to supply XCarb to Knauf Interfer
ArcelorMittal will supply German distribution group Knauf Interfer with CO2-reduced input material, Kallanish learns from the steelmaker.
At ArcelorMittal Europe – Flat Products, CO2 savings are achieved with the “XCarb recycled and renewably produced” label and also through the sale of “XCarb Green Steel Certificates” in line with customer requirements, the steelmaker says.
In partnership with ArcelorMittal Europe – Flat Products, Knauf Interfer will soon be using the “XCarb recycled and renewably produced” product in series production for several customer projects.
Knauf Interfer, in turn, can pass these CO2 savings on to its customers. In this way, the two partners want to safeguard the supply chain. Knauf is thus forming a central interface between steel manufacturers and customers, both through its steel service centres and through its own forming blanks and cold rolling activities, ArcelorMittal explains.
Knauf Interfer processes the steel into slit strip, sheets, formed blanks or cold-rolled precision steel for applications in segments such as drives, engines or seats.

Tubemaker Wiederholt sources CO2-reduced steel from ArcelorMittal
Wiederholt, a German producer of precision steel tube, and ArcelorMittal have signed a memorandum of understanding to use CO2-reduced steel in production, Kallanish learns from the steelmaker. Both companies have been working together for several decades.
As part of the partnership, Wiederholt intends to source hot-rolled steel from ArcelorMittal with CO2 savings of up to 65% compared to traditional production methods.
The CO2 reduction will be achieved through “XCarb Green Steel certificates” and steel with the “XCarb recycled and renewably produced” label. According to ArcelorMittal, at least 75% recycled scrap is used in the production of this steel. The CO2 savings that Wiederholt can pass on to its customers are verified by environmental product declarations (EPDs), the steelmaker says.
Wiederholt’s precision steel tube is mainly used in the automotive industry, including shock absorbers, camshafts, steering parts, cardan shafts and stabilisers. It has committed to becoming carbon neutral in Scope 1 and 2 emissions by 2030, in accordance with the Greenhouse Gas Protocol.
Separately, ArcelorMittal Germany has announced that its Duisburg long products mill has been certified by organisation ResponsibleSteel, following a two-year audit by inspection company GUTcert.
