ArcelorMittal's path towards carbon-neutral steel production
"Enable high-performance design by using less but stronger steels for resistance-driven elements. Engage with manufacturers to understand the industry's realities and where embodied carbon lies in your project.
And most importantly: act early, collaborate, and be willing to think outside the box, as time can be the enemy of sustainability."
- Marion Charlier, PhD, Advanced Building Solutions and Sustainability Lead at ArcelorMittal
