ArcelorMittal Kirchberg

The future world headquarters of ArcelorMittal is currently under construction on avenue John F. Kennedy, in the Kirchberg district of Luxembourg City. Innovative and responsible, it pays tribute to Luxembourg steel with 10,000 tonnes produced in Luxembourg. Called ArcelorMittal Kirchberg Headquarters, it will house management functions for the entire Group worldwide from 2026.

A modern, responsible and “made in Luxembourg” building

Designed by the architectural firm Wilmotte et Associés, with the mission of "designing a modern and sustainable building that exploits the full potential of steel from top to bottom", the new ArcelorMittal headquarters is a showcase of the use low-emission steel in sustainable construction. The building incorporates 10,000 tonnes of ArcelorMittal steel, mainly produced in Luxembourg from XCarb^® recycled and renewably produced steel whose carbon footprint is seven to eight times lower than that of conventional steel, representing a saving of more than 10 tonnes of CO₂ per beam.

The building has a crystal appearance, spirals outward and opens onto the city through a green façade. ArcelorMittal Kirchberg Headquarters offers flexible and modular work and living spaces to guarantee an excellent working environment for employees. For example, each of the 2,600 workstations will benefit from natural light. The building will be fully compliant with three major environmental labels:

BREEAM [1], outstanding level
DGNB [2], Platinum level
WELL [3], Gold level 1

Our new global headquarters is the perfect symbol of ArcelorMittal’s purpose: “smarter steels for people and planet.
Aditya Mittal, CEO ArcelorMittal

The construction of the new ArcelorMittal headquarters in the Grand Duchy marks the desire to perpetuate and deepen the historic link between the country and the steel industry. This is a strong signal of the group’s desire to invest in Luxembourg. This is recognition of the quality of our Luxembourg steels, which represent nearly 90% of all the steel integrated into this building.
