There are substantial costs associated with the assessment and remediation of historical soil and groundwater contamination. We periodically review contamination at our sites, taking remedial action when required, and have procedures to prevent new contamination. Our Environmental Affairs Group provides support for managing these issues professionally and effectively and is also a key contributor to an integrated legacy management approach across the company.
In line with IFRS accounting rules, we make provisions for environmental remediation costs when it is probable that liability will materialize and the cost can be reasonably estimated. We have set aside €419 million which we believe is sufficient for the sites where we have ownership or responsibility (see also notes , and in the Financial statements).
