In 2020, ONEOK began reporting sustainability information using SASB’s standards for reporting financially material impacts. In addition to focusing on topics of financial materiality, SASB provides industry-specific disclosure standards which aim to drive consistency and comparability of sustainability reporting. The table below provides ONEOK’s performance data aligned with the recommended metrics for the SASB Extractives and Minerals Processing – Oil and Gas Midstream Sector (EM-MD, Version 2018-10).
