HOUSTON, Dec. 5, 2017 – Apache Corporation (NYSE: APA) (Nasdaq: APA) today announced it has joined the Environmental Partnership, a collaboration among 25 natural gas and oil producers to accelerate environmental performance improvements in operations across the country. The partnership will leverage knowledge and expertise within the industry to develop best practices, technologies and innovations that reduce emissions. Companies will begin implementing the voluntary program January 1, 2018.

"The Environmental Partnership compliments Apache's existing efforts to reduce emissions including our membership in the ONE Future Coalition, an industry group that focuses on identifying policy and technical solutions that yield continuous improvement in the management of methane emissions associated with the production, processing, transmission and distribution of natural gas. We look forward to applying learnings from the Environmental Partnership to our overall efforts that reduce emissions from operations," said John Williams, director of Corporate Health, Safety & Environmental (HSE).

Through the ONE Future Coalition, Apache Corporation has pledged to target 0.36 percent or less of methane emitted by 2025. The company has already reduced methane emissions by 12 percent from 2015 levels.

The Environmental Partnership program includes three focus areas including a leak detection and technology program for production sources, a program to replace, remove or retrofit high-bleed pneumatic controllers, and a program for manual liquids unloading for natural gas production sources.

"This groundbreaking partnership further demonstrates the industry's leadership and commitment to responsibly developing America's energy resources while reducing emissions," said Jack Gerard, president and CEO of the American Petroleum Institute. "U.S. methane emissions have fallen over the past decade as domestic natural gas and oil production has increased significantly due to the industry's technology innovation and efforts to increase efficiencies. The Environmental Partnership seeks to accelerate emissions reductions, and we're headed in the right direction."
