Sustainability

Materiality Assessment

Why It Matters

Focusing on What Matters Most

To remain resilient and deliver long-term value, it is crucial that we proactively identify and manage the issues that matter most to our business and our stakeholders. Our materiality assessment is a core part of this process, helping us to stay on top of industry trends, navigate operational challenges, and meet stakeholder expectations. By identifying and prioritising these key matters, we can focus on our efforts and resources where they will have the greatest impact.

Our Approach

We conduct materiality assessment as a cornerstone of our sustainability strategy. This comprehensive process allows us to identify risks and opportunities that may influence our business while also evaluating the impact of our operations on nature. We annually review these material matters, risks and opportunities to ensure our sustainability strategy remains relevant and responsive to a changing landscape.

Our process is designed for comprehensive coverage and relevance. We engage with a wide range of key stakeholders, including our suppliers, customers, investors, and policymakers. In conducting our assessment, we refer to leading industry frameworks, such as the Sustainability Accounting Standards Board (SASB) and the European Sustainability Reporting Standards, to ensure our approach is aligned with global best practices.
