Appalachian Basin Once Again Confirmed as Lowest Methane Intensity Major Oil and Gas Basin in the United States

prnewswire.com
CNX CNX Resources is mentioned as a member operator of the Appalachian Methane Initiative, which released a study confirming the Appalachian Basin has the lowest methane emissions intensity. The article focuses on the study's findings and the initiative's work, not specifically on CNX's individual performance or outlook. EQT EQT Corporation is listed as a member operator of the Appalachian Methane Initiative. The article highlights the initiative's study on methane emissions in the Appalachian Basin, positioning EQT as part of a group working towards lower emissions, but without specific sentiment towards the company itself. MPLX MPLX LP is identified as a member operator of the Appalachian Methane Initiative. The article discusses the positive findings of the initiative's methane emissions study in the Appalachian Basin. MPLX is included as part of this collaborative effort, but the sentiment is directed towards the initiative and the basin, not the company individually. AR Ascent Resources is mentioned as a data contributing operator to the Appalachian Methane Initiative. The article focuses on the positive findings of the initiative's methane emissions study in the Appalachian Basin. Ascent is part of this group, but the sentiment is neutral towards the company itself.

Appalachian Basin Once Again Confirmed as Lowest Methane Intensity Major Oil and Gas Basin in the United States Appalachian Methane Initiative Releases 2025 Study

PITTSBURGH, March 20, 2026 /PRNewswire/ -- The Appalachian Methane Initiative (AMI) – a coalition of leading U.S. natural gas companies working in collaboration with independent monitoring providers, technical consultants, and top-tier universities – today released the findings of its 2025 basin-wide methane monitoring program.

The 2025 report marks the second annual comprehensive study and represents a significant expansion in geographic coverage, survey frequency and measurement technologies. The results confirm, once again, that the Appalachian Basin has the lowest methane emissions intensity of any major oil and gas-producing basin in the United States.

The study, conducted in collaboration with the Energy Emissions Modeling and Data Lab (EEMDL) at The University of Texas at Austin and Colorado State University, with support from SLR International (SLR), utilized nearly 17,000 unique surveyed sites measurements across approximately 31,800 square miles (82,360 square kilometers) of the Appalachian Basin. Surveys were conducted between March and October 2025 using Bridger Photonics, Insight M and ChampionX technologies, covering nearly 6,600 oil and gas sites and approximately 140 non-oil and gas sites, including coal mines and landfills.

Together, AMI member operators, including CNX Resources, EQT Corporation, MPLX and Seneca Resources, along with data contributing operators Ascent Resources and Expand Energy Corporation (all collectively referred to herein as "AMI Operators"), represent approximately 17.9 billion cubic feet per day (bcfd) of natural gas production, accounting for more than 50% of the basin's total production.

Key Findings of the 2025 Report Include:

The Path Forward

The AMI 2025 study underscores the value of coordinated, large-scale, multi-technology methane measurement combined with rigorous scientific analysis and operational data integration. The expansion of survey coverage to nearly 98% of basin production and the addition of independent measurement methods strengthened confidence in basin-wide extrapolations and emissions intensity estimates.

Lessons from the 2025 campaign will inform future efforts, including:

"The Appalachian Methane Initiative is one of the world's most comprehensive methane emissions measurement and mitigation campaign across oil and gas operations. Unique to this initiative is the integration of multi-scale measurements with operational investigation enabling effective, rapid, and observable emissions reduction," said Arvind Ravikumar, faculty member at The University of Texas at Austin and EEMDL Co-Director. "The AMI campaign provides a global blueprint for operators to not just plan for but achieve low emissions natural gas supply chains."

About AMI:

The Appalachian Methane Initiative is a coalition of leading U.S. natural gas companies engaged with independent monitoring providers, technical consultants, and leading universities. Through a coordinated strategy to methane monitoring and a cooperative approach to emissions reduction best practices, the coalition aims to further enhance methane emissions monitoring and reductions throughout the Appalachian Basin.
