Data Verification & Assurance

Independent data assurance and verification processes for our Sustainability Report are conducted at both the local facility and Group levels by independent third parties.

Asset Level Data

Environmental and some selected social performance data of operationally controlled assets, which have been operating for a full calendar year, have been independently verified by an external service provider directly engaged by each asset in the different countries in which they operate. Our aggregated Group Sustainability Report data makes use of the verification work done at the asset level. Our verified asset level data are accessible via our Asset Performance Statistics, available here.
