For added confidence, we seek further assurance that what we report is accurate. These internal systems, processes, and external bodies ensure that our reporting is credible.
Internal Assurance
Monitoring performance against sustainability criteria can be complicated. We use a number of processes internally to make sure we are accurate in our reporting.
External assurance
We work with a number of external companies to ensure we meet the highest standards, to provide challenges, and to ensure that our systems, processes and reporting are robust.
Bureau Veritas
Our sustainability data is audited annually by Bureau Veritas. This audit includes a statement of verification which covers the materiality and quality of data reported.
