Our sustainability initiative focuses on our most significant sustainability issues and opportunities. These are defined by our materiality assessment, which identifies and prioritises issues. In 2023, we updated our materiality assessment. We adopted the double materiality methodology laid out in the ESRS, which identifies and prioritises issues based on two dimensions: the impact or likely impact of Vesuvius on society and the environment, and the impact on Vesuvius’ business, creating financial risks and opportunities for Vesuvius.

Vesuvius materiality assessment


Five topics are retained as material:

Five topics were also identified that are in the extended strategic focus but not subject to formal reporting requirements:
