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 also sets additional ESG-related targets annually. These targets promote continuous improvement and communicate our high expectations for leadership and employees.
Absolute 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 2022, we had achieved reductions totaling approximately 0.5 MMT, or approximately 20% toward our targeted 2.2 MMT reductions.
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. In 2022, we achieved our second best AREER performance since the establishment of this metric. Our 2023 target represents a more than 10% improvement over 2022 performance and emphasizes ONEOK’s expectation for continued improvement.
Safety and Health
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. In 2022, ONEOK achieved its best ever TRIR results on record.
