Sustainability reporting and governance
We have enhanced our sustainability reporting practices over the past 25 years. Each year, we aim to improve clarity, consistency and data quality across our sustainability reporting documents. To incorporate external perspectives, we conduct a formal materiality1 assessment every two years, review our material1 topics annually, and continually monitor our operating environment for emerging issues that may affect our business, including our sustainability reporting practices.
Our prioritization process
To gain insight into the issues of greatest importance to our business, our shareholders and our stakeholders, we carried out a double materiality1 assessment in 2025. We assessed sustainability topics through a dual lens: the impact that these topics have on the Company and the Company’s impact on the economy, people and the environment. The Sustainability Committee of the Board of Directors (Board) reviewed the results of this assessment.
Sustainability governance
Oversight of sustainability matters is integrated into the responsibilities of the Board and all five of our Board committees. This governance structure promotes accountability, supports our progress against sustainability goals and enables continuous improvement.
