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.

Third-Party Reporting

ONEOK’s Corporate Sustainability Report is researched and compiled by a collaboration of corporate business segments with final review and approval by ONEOK executive management.

We engaged an external third party to perform attestation procedures for certain environmental and safety metrics disclosed in ONEOK’s ESG Performance Data and in our report. Metrics receiving limited third-party assurance are noted in the ESG Performance Data.

Forward-Looking Statements


Some of the statements contained and incorporated in this report are forward-looking statements as defined under federal securities laws. We make these forward-looking statements in reliance on the safe harbor protections provided under federal securities legislation and other applicable laws. These statements are not guarantees of future results, occurrences or performance. The following discussion is intended to identify important factors that could cause future outcomes to differ materially from those set forth in the forward-looking statements.

Any statements other than statements of historical fact should be considered forward-looking statements. Forward-looking statements include the information concerning possible or assumed future results of our operations and other statements contained or incorporated herein identified by words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “goal,” “guidance,” “intend,” “may,” “might,” “outlook,” “plan,” “potential,” “project,” “scheduled,” “should,” “target,” “will,” “would,” and other words and terms of similar meaning.

  • The effectiveness of our risk-management function, including mitigating cyber- and climate-related risks;
  • Our ability to identify and execute opportunities, and the economic viability of those opportunities, including those relating to renewable natural gas; carbon capture, use, and storage; other renewable energy sources such as solar and wind; and alternative low carbon fuel sources such as hydrogen;
  • The ability of our existing assets and our ability to apply and continue to develop our expertise to support the growth of, and transformation to, various renewable and alternative energy opportunities, including through the positioning and optimization of our assets;
  • Our ability to efficiently reduce our GHG emissions (both Scope 1 and 2 emissions), including through the use of lower carbon power alternatives, management practices and system optimizations;
  • The necessity to focus on maintaining and enhancing our existing assets while reducing our Scope 1 and 2 GHG emissions;

  • The profitability of assets or businesses acquired or constructed by us;
  • The risks associated with pending or possible acquisitions and dispositions, including our ability to finance or integrate any such acquisitions and any regulatory delay or conditions imposed by regulatory bodies in connection with any such acquisitions and dispositions;
  • The length, severity and reemergence of a pandemic or other health crisis, such as the COVID-19 pandemic and the measures taken to address it, which may (as with COVID-19) precipitate or exacerbate one or more of the factors herein, reduce the demand for natural gas, NGLs and crude oil and significantly disrupt or prevent us and our customers and counterparties from operating in the ordinary course of business for an extended period and increase the cost of operating our business.; and
  • Those factors listed under “Forward-looking Statements” in our Annual Report on Form 10-K for the fiscal year ended Dec. 31, 2022 (2022 Annual Report), and in our other filings that we make with the United States Securities and Exchange Commission (SEC), which are available via the SEC’s website at and our website at

These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other factors could also affect adversely our future results. These and other risks are described in greater detail in Part I, Item 1A, Risk Factors, in our 2022 Annual Report and in our other filings that we make with the SEC, which are available via the SEC’s website at and our website at All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these factors. Any such forward-looking statement speaks only as of the date on which such statement is first made, and other than as required under securities laws, we undertake no, and expressly disclaim any, obligation to update publicly any forward-looking statement whether as a result of new information, subsequent events or change in circumstances, expectations or otherwise. We also do not, and do not intend, to independently verify third-party data contained in this report or used in the estimates and assumptions necessary to certain matters discussed in this report.

This report contains statements based on hypothetical or severely adverse scenarios and assumptions, and these statements should not necessarily be viewed as being representative of current or actual risk or forecasts or expected risk. While the future events and current scenarios and efforts discussed in this report may be significant, any significance should not be read as necessarily rising to the level of materiality as that term is defined for the purposes of compliance with the U.S. federal securities laws or disclosure regulations promulgated thereunder, even if we use the word “material” or “materiality” in this report or in other materials we may release from time to time in connection with the matters discussed in this report. Moreover, given the uncertainties, estimates and assumptions inherent in the matters discussed in this report, and the timelines involved, materiality is inherently difficult to assess far in advance. In addition, given the inherent uncertainty of the estimates, assumptions and timelines associated with the matters discussed in this report, we may not be able to anticipate in advance whether or the degree to which we will or will not be able to meet our plans, targets or goals.
