1. The Canadian Association of Petroleum Producers (CAPP) has developed a reporting framework called the Stewardship Initiative. For CAPP and its members, stewardship is about the continuous improvement and transparent reporting of environmental, health, safety and social performance. Nexen has achieved the highest level, Platinum status, in stewardship reporting.
    
2. Nexen is a member of the International Petroleum Industry Environmental Conservation Association (IPIECA), which introduced voluntary sustainability reporting guidelines in 2005.
    
3. The Global Reporting Initiative (GRI) is a popular standard for sustainability reporting. In 2006, Nexen reported on approximately 55% of the GRI’s core indicators. Where we see business and stakeholder value, we are incrementally adding new GRI indicators to our report and this website.

In addition to these three guidelines, our reporting is influenced by our participation in Responsible Care®, the United Nations Global Compact initiative and Canadian Business for Social Responsibility.
