The future of steel sustainability: In conversation with Philippe Aubron, Head of Global Automotive at ArcelorMittal

Philippe Aubron, ArcelorMittal’s Head of Global Automotive, joined ResponsibleSteel’s Board of Directors earlier this year. We asked him a few questions on the industry’s most promising developments, growing demand for sustainable, low-emission steel, and the value of ResponsibleSteel in supporting the shift towards sustainable practices.

1. You’ve witnessed the steel industry evolve significantly over the past three decades. What do you think are the most important changes shaping the sector today?

Over the past 30 years, the steel industry has undergone a profound transformation. Today, the most significant change is the shift toward sustainability and decarbonisation. This is driven by both regulatory pressure and customer demand, particularly in sectors like automotive. Digitalisation and advanced manufacturing technologies are also reshaping how we produce and use steel, enabling greater efficiency, traceability, and innovation. The industry is no longer just about volume and cost—it’s about value, responsibility, and long-term impact.

2. What role do you see ResponsibleSteel playing in helping the industry deliver on its sustainability commitments?

ResponsibleSteel provides a credible, independent multistakeholder standard that supports transparency and continuous improvement across a broad range of ESG criteria. It helps steelmakers demonstrate responsible practices and gives customers confidence in the sustainability of their supply chains. Importantly, ResponsibleSteel is also working to align with other standards, such as the Low Emission Steel Standard (LESS) and the Initiative for Responsible Mining Assurance, to ensure interoperability and reduce complexity for producers and customers alike. This harmonisation is essential to building trust and accelerating the transition across the industry.

3. What value does ArcelorMittal see from being part of ResponsibleSteel?

The ResponsibleSteel International Production Standard is not just about emissions—it encompasses over 500 ESG criteria, from biodiversity to human rights. As the industry evolves, ResponsibleSteel will be instrumental in setting credible benchmarks and enabling customers to make informed choices. The Production Standard has been warmly received by all ArcelorMittal sites that have undertaken the certification process, which proved valuable in helping to identify opportunities to further improve ESG practices and performance. It has served to strengthen our management systems, ensuring we continue to embed robust ESG standards across our operations.

4. Where (regionally or technologically) do you see the most promising developments in sustainable steel production emerging?

ArcelorMittal is already producing low carbon emission steel in various locations around the world, although Europe remains a frontrunner due to its regulatory ambition. However, the technological path is complex and requires strong policies to address global steel overcapacity, unfair trade, carbon leakage, clean energy cost and availability, and prioritising scrap for circularity and decarbonisation within the EU. A framework to address these issues and more was set out by the European Commission in its Steel and Metals Action Plan which was published earlier this year. However, what is lacking is speed of implementation—the framework outlined in the Steel and Metals Action Plan needs to be converted into effective legislation. We remain hopeful that this can be achieved as soon as possible.

5. As Head of Global Automotive for ArcelorMittal, how is demand for low-emission and sustainable steel evolving among automotive customers? What are going to be the industry’s biggest challenges in meeting this demand?

Automotive OEMs are increasingly integrating sustainability into procurement, driven by Scope 3 emissions targets and consumer expectations. Demand for low-carbon steel is gradually increasing, but the real challenge lies in scaling supply to meet demand at a competitive cost. While some customers are already securing volumes for upcoming vehicle launches, the majority remain hesitant to absorb the higher cost associated with the 'green premium'—despite clear signals that the shift is underway. The industry must overcome high production and energy costs, limited availability of green inputs, and the need for harmonised standards. Also, more work can be done to increase circularity—for example, scrap steel buybacks—and recycling, and therefore create closed loops.

6. What drew you to join the ResponsibleSteel Board at this moment in the industry’s transition?

This is a pivotal moment for the steel industry. The decisions we make now will shape the sector’s impact on climate, communities, and the economy for decades to come. I joined the ResponsibleSteel Board to help ensure that the transition is ambitious, credible, and inclusive. With my background in automotive and global operations, I hope to bring a practical perspective to the table and help bridge the gap between producers and end-users.
