To complement our existing HSE&SR audits and inspections, we conduct a two-pronged external review process for our sustainability reporting.

The sustainability practice group at PricewaterhouseCoopers (PwC) reviewed selected quantitative information in Nexen’s Sustainability Report 2006 and provided the conclusion that the data in the report is stated fairly. PwC’s review is available on page 43 of the Sustainability Report 2006.

We also assembled a team of diverse experts and stakeholders representing Nexen’s employees; communities where we operate (Balzac, Alberta; Wood Buffalo, Alberta; Lloydminster, Alberta/Saskatchewan); non-governmental organizations (Pembina Institute); youth (University of Calgary student); academia (University of Calgary); and First Nation (Siksika Nation). The Pembina Institute’s multistakeholder evaluation of Nexen’s Sustainability Report 2006 is available on page 42 of the Report.
