Standards and Frameworks

To help guide ONEOK’s environmental, social and governance (ESG) performance disclosures, we reference several recognized reporting standards and frameworks, including the Sustainability Accounting Standards Board (SASB) and Global Reporting Initiative (GRI) standards for voluntary ESG reporting and Task Force on Climate-related Financial Disclosures (TCFD) recommendations for voluntary disclosure of climate risks and opportunities. For SASB reporting, ONEOK references the Extractives and Minerals Processing Sector – Oil and Gas Midstream (EM-MD, Version 2018-10) standard. For GRI reporting, ONEOK references GRI 1: Foundation 2021 (available as of Oct. 5, 2021) and GRI 11: Oil and Gas Sector Standard 2021. Additionally, ONEOK reports industry-specific ESG data aligned with the Midstream ESG Reporting Template, developed by the Energy Infrastructure Council (EIC) and GPA Midstream Association.
