the core of our business

We strive to keep our footprint light, like the material our business is based upon. We celebrate the inherent sustainability of aluminium which not only increases efficiency by reducing weight, but can be recycled without losing its properties. We prioritize the safety and well-being of our employees and communities, and we embrace a circular economy for the health of our planet.

Commitment to sustainability

Our company’s deep commitment to sustainability influences the business decisions we make, how we treat people, and the ways in which we create value. We conducted a Materiality Assessment to understand better the expectations from our stakeholders, and we created a Sustainability Council containing representatives from all facets of our business. We have been working hard to achieve our 2020 Sustainability targets. Annually, we track our performance and ensure accurate and transparent disclosure of sustainability data. For more information, please see our 2018 Business and Sustainability Report.

A value chain approach

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.

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 Standard certificate in August 2019. It is an important milestone and recognition of our sustainability efforts.
