Global Reporting Initiative

AEP’s 2017 Corporate Accountability Report was prepared according to the Global Reporting Initiative (GRI) Sustainability Reporting Guidelines Version 4 (G4). The GRI guidelines provide a voluntary reporting framework used by organizations around the world as the basis for sustainability reporting. We are using the G4 standards, as well as the Electric Utility Sector Supplement, for reporting on industry-specific information.

In 2016, GRI migrated from being a voluntary framework to a set of standards. AEP is not reporting against the standards in this report. We will evaluate the use of the new standards and determine how to apply them in the future to our already robust disclosure.
