We measure company health, safety and environmental (HSE) performance using a range of leading and lagging indicators. Leading indicators include metrics for training, leadership commitment, employee involvement and the quality of incident investigations. Lagging indicators include incidents, near misses and days away from work. Leading indicators help drive continuous improvement in our safety performance, while lagging indicators help us assess the success of our safety management efforts. All SWN employees and contractors are evaluated on and held accountable for HSE performance. We are committed to continuous improvement and hold all employees – including senor management – accountable to this goal with year-over-year HSE performance targets.

In 2020, not only did we achieve record safety performance for TRIR, DART and TRER, but we also achieved top quartile performance among our peers in safety, driving and environmental performance.
