ONEOK Performance Targets

In September 2021, ONEOK announced a companywide greenhouse gas (GHG) emissions reduction target. ONEOK also sets additional ESG-related targets annually. These targets, which are highlighted below, promote continuous improvement and communicate our high expectations for leadership and employees.

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's GHG reduction target is not included in the company's STI Plan. 


Absolute GHG Emissions Reduction Target

We have targeted a 2.2 million metric ton (MMT) reduction of our combined Scope 1 and Scope 2 emissions by 2030 (a 30% reduction in total operational emissions attributable to ONEOK assets in 2019). 

Emissions reduction opportunities include:

Agency Reportable Environmental Event Rate (AREER) 

AREER is an internal environmental metric that promotes continued reductions in releases and emissions events reportable to a state or federal agency. The AREER metric has been an element of ONEOK’s STI Plan for all employees since 2014. 

Since implementation of the metric, we have seen substantial overall reductions in our AREER rate, with the exception of 2021 performance. Our 2022 target represents a nearly 5% improvement over 2020 performance and emphasizes ONEOK's expectation for continued improvement.  

 2017  2018  2019 2020 2021 2022 Target
 1.23 1.05 0.79 0.42 0.80 0.40


Total Recordable Incident Rate (TRIR)

TRIR is the number of Occupational Safety and Health Administration (OSHA) recordable injuries and illnesses per 200,000 work hours. TRIR is part of our STI Plan performance criteria for all employees. Inclusion of this metric is designed to emphasize ONEOK’s commitment to safe operations and to reward safe behavior throughout the company.  

2017 2018 2019 2020 2021 2022 Target
0.78 0.58 0.32 0.69 0.45 0.31
