Global Reporting Initiative Index

Duke Energy uses the GRI Sustainability Reporting Standards to help guide our reporting. This index is based on the most recent versions of the Standards available as of May 2020 and includes the Electric Utility Sector Supplement. For most indicators, we refer users to information on our website or other public documents. For some indicators, we provide brief narrative responses. Most data in this index address calendar year 2020, in coordination with our most recent Sustainability Report.
