The materiality assessment was used as a tool for mapping the most important topics for disclosure and reporting. In 2020 we updated the materiality matrix with an internal group composed of senior management and subject-matter experts. This group ranked 44 value creating topics by scoring them on a scale of 1 to 5. We averaged the results of this survey per topic. This input was then used to design a materiality matrix with the most relevant topics for our organization and portfolio. The matrix plots the relevance and importance of topics for both stakeholders and on the value creation for the company.
The Integrated Reporting Framework, published by the IIRC (International Integrated Reporting Council), and the Global Reporting Initiative, are used as the basis for its corporate reporting. Materiality is an important concept for both frameworks. In our approach, we have taken both frameworks into account to define our materiality matrix.
