We participate in numerous associations and initiatives aiming at improving industry sustainability in our different markets. Through these actions, we engage with our customers, suppliers, regulators, and NGOs. Stakeholder engagement also happens through regular one-to-one dialogue, particularly with customers and suppliers, whom we expect to share our values.

We take strict measures to ensure responsible sourcing. Our initiatives have earned us external recognition from various bodies, including EcoVadis.

Sourcing and Suppliers

At Constellium, sustainability does not simply mean establishing our own social, environmental, and ethical standards, but also ensuring that our values are reflected across the supply chain. Our responsible sourcing policy relies on commitment, assessment, and progress.

Our Supplier Code of Conduct

We only want to work with suppliers who are as serious about sustainability as we are. We have a dedicated Responsible Supply Chain Management Policy and Supplier Code of Conduct aligned with UNGC principles. It applies to Constellium’s suppliers, subsidiaries, consultants, contractors, and affiliates. For any inquiries or concerns regarding non-compliance with our Responsible Supply Chain Management Policy, please contact us at sustainability(at)constellium.com

Assessment of our Suppliers

We are evaluating all our key suppliers with the EcoVadis assessment. We also conduct on-site audits of suppliers identified as carrying the most risk.


Evaluations and audits are not a tick-box exercise but translate into specific actions by our purchasing team.


The Aluminium Stewardship Initiative (ASI) is a global, multi-stakeholder, non-profit standards setting and certification organization. It works towards responsible production, sourcing, and stewardship of aluminium, following an entire value chain approach. Through extensive stakeholder participation and consultation, ASI has designed Standards that provide a shared platform to address key issues and create B2B incentives for their implementation.

ASI certification logoASI’s new Certification program covers all stages of the value chain for aluminium, including bauxite mining, alumina refining, aluminium smelting, semi-fabrication, product design and manufacturing, and recycling. The ASI’s Performance Standard covers critical issues for the entire aluminium value chain including greenhouse gas emissions, waste management, material stewardship, biodiversity and human rights.  ASI’s Chain of Custody (CoC) Standard links responsible production with responsible sourcing and thus increases the emphasis on sustainability issues in procurement.

As a founding member of the ASI, we actively helped launch its Certification program including Performance Standard and Chain of Custody Standard in December 2017. Our casting and rolling operations in Singen, Germany, have received the Aluminium Stewardship Initiative (ASI) Performance & Chain of Custody Standard certificate in 2019 and started producing ASI certified products for our customers in 2020. Our extrusion lines in Singen and our Automotive Structures operations in Gottmadingen and Dahenfeld, Germany have received the ASI’s Performance Certificate in October 2020. As of December 1, 2020, our Neuf-Brisach facility in France has been fully certified with the ASI Performance and Chain of Custody standards. This will allow our plant to provide ASI certified products, by sourcing from ASI-certified suppliers and also directly from our recycling unit. It is an important milestone and recognition of our sustainability efforts.

We will continue to certify other sites of our operations and help our key metal suppliers with their certification processes, to foster the contribution of aluminium to a sustainable society.
