Data and how we report
Identifying material sustainability issues
Building on the materiality assessment conducted in 2023, we worked with an external agency to validate the assessment for the purposes of the 2024 sustainability report, considering the external landscape and developments relating to sustainability and ESG.This process identified no significant changes from 2023.
Verification and assurance
Our verification methods include data reviews by reporting businesses and subject matter experts, second line functional and group reviews as well as third line reviews by internal audit.
We ask Deloitte to provide limited external assurance for several key sustainability metrics to the internationally recognized ISAE 3000 (revised) standard. Read the Deloitte assurance statement on page 48 of the Sustainability Report 2024.
Our basis of reporting outlines the approach and scope used for data collection and forms the basis for assurance of sustainability performance data.
