Materiality
Assessment

A Materiality Assessment allows us to know what topics matter most to our stakeholders, so that we can align our sustainability efforts with their priorities. Constellium conducted a first Materiality Assessment in 2014, surveying top managers and external stakeholders. In 2017-2018, we broadened the scope. An independent third-party company surveyed around 100 internal stakeholders (top managers and other employees) along with 100 external stakeholders (investors, suppliers, and customers). Roughly half came from France and Germany, 14% from North America, and 34% from the rest of the world.
