Global Reporting Initiative Index to Indicators
We use the Global Reporting Initiative (GRI) Sustainability Reporting Guidelines to help guide our reporting. This index is based on GRI Versions 3.1 (G3), and G4, and includes the Electric Utility Sector Supplement (EUSS).
Indicators specific to the EUSS are shown as EU(#). For many indicators we refer users to information on our Web site or other public documents. For other indicators we provide brief narrative responses. Most data in this index address calendar year 2014, in coordination with our most recent Sustainability Report.
