Report Parameters

This report contains information on the economic, environmental, and social responsibilities of Southern Company and its subsidiaries. To reduce use of energy and natural resources in the production of this report, and to gain more timely opportunity to update it, we're publishing it online.

Find relevant performance data at the end of each section of the report. Figures generally reference five-year trends through December 31, 2012, except where unavailable or otherwise noted. Environmental data is from our generating plants. News and significant events cover the past two years. We update the report with current data as it is released.

To best meet the full range of expectations among our stakeholders, the organization of content in our report is largely based on Global Reporting Initiative guidelines. (The Global Reporting Initiative is a multi-stakeholder group seeking to provide a trusted and credible framework for sustainability reporting for any company. For more on GRI, visit www.globalreporting.org.) Applicable subjects from the guidelines are indexed to the pages that fulfill each respective section.

To determine the materiality of topics included in the GRI guidelines, we survey peers, review policy and plans from management and directors, and compile data from regulated and voluntary activities. After drafting the report and reviewing it internally, we circulated advance copies to a review panel of external stakeholders including investors, media, environmental groups, sustainability reporting experts, and peers. All comments were considered and many were incorporated into the final report. Others will help shape future actions. Several stakeholder quotes are posted in the report to balance our viewpoints on key issues.

In response to requests by shareholders, we have produced other reporting and disclosure materials in addition to this report. Find many of these materials at contacts and notices.

To help us make the report more useful and complete, we will incorporate suggestions by stakeholders to an early release of this information. We welcome you to add to this feedback and send your comments by e-mail.
