We engaged two third-party organizations to provide independent assurance of the content of our reporting in 2021.

Bureau Veritas has provided independent assurance of the accuracy, reliability and objectivity of the information included in our Creating Share Value and Sustainability report, and that it covers our material issues. The assurance process was conducted in line with the requirements of the AA1000 Assurance Standard (AA1000AS v3) Type 2 at moderate level of assurance.
