Assurance
Our Corporate Assurance function has accountability and responsibility for providing internal assurance to the management, directors and board committees that our policies, standards and controls are:
- Adequately designed and effective for their intended purpose
- Consistently implemented by all Rio Tinto sites on a timely basis and as designed
- Working effectively
In addition, we have used the independent professional services firm PricewaterhouseCoopers to assure selected Group level sustainable development performance data across four specific sustainable development risk areas. A statement from PricewaterhouseCoopers and the criteria against which they provided their assurance are available below:
