ONE FUTURE WELCOMES ASCENT RESOURCES, BOARDWALK PIPELINES, AND EQUITRANS MIDSTREAM CORPORATION

-NATURAL GAS COALITION MEMBERSHIP REACHES 20-

November 19, 2019 – Our Nation’s Energy Future (ONE Future) announced three new coalition members today – Ascent Resources, LLC., Boardwalk Pipelines, LP (Boardwalk) and Equitrans Midstream Corporation (NYSE: ETRN), bringing the total number of member companies to 20.

“We welcome these three new members to the ONE Future initiative,” said Richard Hyde, Executive Director, ONE Future. “I know these memberships will give meaningful value to our Board’s efforts and the positive reporting that the Coalition is releasing. These companies are joining a group of like-minded progressive companies that are intent on reducing methane emissions to help ensure the competitiveness of natural gas into the future.”

ONE Future member companies represent the entire natural gas value chain and account for approximately 10% of the total natural gas production, 40% of the US natural gas transmission miles and 9% of the US natural gas distribution. ONE Future companies work with each other to promote best practices and share learnings on each company’s respective science-based, technology and methods for methane reduction; though each member always has the flexibility to deploy its capital where it will be most effective.

As ONE Future members, each company will report its 2019 methane results as part of the production, gathering and boosting, processing, and transmission and storage sectors within the coalition and will hold a seat on ONE Future’s Board of Directors. The 2018 Methane Intensity Report was just released and the coalition registered a 2018 methane intensity number of 0.326%, a decrease of 41% from 2017, demonstrating that the natural gas industry can minimize methane emissions and increase production and throughput while supplying much needed energy to the U.S. and around the globe.
