Constellium uses materiality assessments to identify sustainability topics affecting our activities and the aluminium value chain over the short, medium, and long term. We consolidate the risks identified and then assess and prioritize those risks.

We conducted our first materiality assessment in 2014, surveying top managers and external stakeholders. In 2017-2018, we broadened the scope by surveying close to 100 internal stakeholders and 100 external stakeholders from around the world. In 2019, with the support of an independent third-party company, we updated our assessment and performed a sustainability risk analysis involving internal top managers. In 2020, we expanded our materiality assessment to allow for more rigorous analysis and deeper insights specifically on the topics of climate change and corruption.
