Performance Targets

Companywide targets set by our board of directors, including performance measures that are part of our Short-Term Incentive (STI) Plan, are detailed below. Targets are based on ONEOK’s historical performance and top quartile peer company performance. ONEOK reviews and updates these targets annually to promote continuous improvement and communicate our high expectations for our leadership and employees. 

AGENCY REPORTABLE ENVIRONMENTAL EVENT RATE (AREER) 

AREER is an internal environmental metric that promotes continued reductions in releases and emission events. The AREER metric has been an element of ONEOK’s STI Plan for all employees since 2014.

AREER is defined as the total number of releases and excess emission events that trigger a federal, state or local environmental-reporting requirement (with some exceptions to account for events outside our control, planned maintenance and disparity in reporting requirements across our operations) per 200,000 work hours.

Since implementation of the metric, we have seen substantial overall reductions in our rate of reportable environmental events. In 2024, we set an AREER target of 0.74, which was established after taking into account the Magellan acquisition. We achieved a result of 0.33, which was 55% below the target goal (representing performance better than our target).

ONEOK's 2025 AREER target is 0.63, reflecting the EnLink and Medallion acquisitions.

SAFETY AND HEALTH

TOTAL RECORDABLE INCIDENT RATE (TRIR)

TRIR is the number of Occupational Safety and Health Administration (OSHA)-recordable incidents per 200,000 work hours. TRIR is also part of our employee STI Plan criteria, emphasizing ONEOK’s commitment to safe operations and rewarding safe behavior throughout the company. ONEOK's 2024 TRIR performance of 0.31 was nearly 23% below the 2024 target goal of 0.40 (representing performance better than our target).

While our ultimate goal remains zero, we continue to work to minimize the impact of workplace incidents.

ONEOK's 2025 TRIR target is 0.37, reflecting the EnLink and Medallion acquisitions.

TRIR reduction 23 percent better than target

ENVIRONMENT

SCOPE 1 AND SCOPE 2 GHG EMISSIONS REDUCTION TARGET

We have targeted a 2.2 million metric ton (MMT) reduction of our combined Scope 1 and Scope 2 GHG emissions by 2030. The target represents a 30% reduction in combined operational Scope 1 and location-based Scope 2 GHG emissions attributable to ONEOK assets as of Dec. 31, 2019. As of year-end 2024, we had achieved reductions totaling approximately 1.7 MMT, or 77% toward our targeted 2.2 MMT reductions.

Following recent acquisitions, we continue to evaluate and anticipate future integration of new operations and associated emissions.
