Our Double Materiality Analysis (DMA), launched in 2024 and based on 2021 analysis, helps align key sustainability efforts with both financial and impact considerations. It identified four material topics that reflect our ongoing focus areas and guide actions that create long-term stakeholder value.

• Climate Change
• Circular Economy
• Workers in the Value Chain
• Own Workforce

Following the initial materiality analysis conducted in 2021, we had already defined four key areas for action: reducing carbon emissions, enhancing circularity, managing suppliers and further developing the company as an attractive employer. These align with the four material topics identified in the current DMA.
