EPA Methane Regulation: A Framework Built, Then Unwound
Methane is the second-largest driver of human-caused warming after carbon dioxide, and it works fast. Over a 20-year window it traps roughly 80 times more heat per ton than CO₂, which makes cutting it one of the few levers capable of slowing warming within a single decade. In the United States, oil and natural gas operations are the largest industrial source of methane, leaking it from wellheads, venting it from equipment, and burning it off through flares. That is why federal methane policy has centered, for more than a decade, on the oil and gas sector.
It has also made methane one of the most politically contested corners of environmental law. The federal rules have been written, rescinded, rewritten, and partially dismantled across four administrations. Understanding where things stand in 2026 requires understanding that whiplash.
The Three Pillars of the 2024 Framework
By the end of 2024, federal methane policy rested on three distinct instruments, each created or strengthened under the Biden administration:
The Clean Air Act standards (NSPS OOOOb / EG OOOOc). Finalized in December 2023 and published in March 2024, this is the core rule. It set New Source Performance Standards for new, modified, and reconstructed oil and gas sources, and — for the first time at the national level — Emission Guidelines directing states to write plans limiting methane from existing sources. The rule pushed operators toward leak detection and repair programs, restrictions on routine flaring, zero-emission equipment standards, and a “super-emitter” program allowing certified third parties to flag large leaks detected by satellite or aircraft.
The Greenhouse Gas Reporting Program, Subpart W. Revised in May 2024 as the Inflation Reduction Act required, this is the measurement backbone. It governs how large oil and gas facilities calculate and report their emissions, and the 2024 revisions pushed reporting toward empirical, measured data rather than generic engineering estimates. Reliable reporting underpins everything else, including the fee described below.
The Waste Emissions Charge. Created directly by Congress in the Inflation Reduction Act, this was a per-ton fee on methane emitted above statutory thresholds by large facilities — set at $900 per metric ton for 2024, rising to $1,200 for 2025 and $1,500 thereafter. Facilities complying with the Clean Air Act standards could eventually become exempt, a design meant to reward reductions rather than simply collect revenue.
Together these formed a layered system: standards to require reductions, reporting to verify them, and a charge to penalize the worst emitters.
How the Rules Got Here: A Decade of Reversals
The current fight is not new. Federal methane regulation has followed a consistent partisan rhythm.
The Obama administration laid the foundation. In 2012 EPA set the first New Source Performance Standards for volatile organic compounds from oil and gas equipment, which curbed methane indirectly. In 2016 it issued standards that targeted methane directly from new sources and began the process — through an information request to operators — of regulating existing infrastructure as well.
The first Trump administration dismantled most of it. Between 2017 and 2020 EPA delayed compliance deadlines, then in 2020 finalized rules that rescinded methane standards across the board and removed the transmission and storage segments from regulation entirely. The 2020 action also sought to narrow EPA’s legal authority to regulate methane in the first place.
The Biden administration reversed course and went further. In 2021 Congress used the Congressional Review Act to nullify the Trump rollback, and EPA began building the expanded 2024 framework described above — notably extending regulation to existing sources for the first time. Internationally, the U.S. and EU launched the Global Methane Pledge in 2021, now joined by more than 150 countries committing to cut collective methane emissions 30 percent below 2020 levels by 2030.
The second Trump administration has moved to unwind the 2024 framework, which brings the story to the present.
Where Things Stand in 2026
The 2024 rules are being dismantled piece by piece rather than all at once. As of mid-2026, here is the state of each pillar:
The Waste Emissions Charge is effectively dead. In February 2025, Congress used the Congressional Review Act to repeal the rule implementing the charge, and subsequent legislation prohibited EPA from collecting it until 2034. The fee technically still exists in the statute — Congress did not repeal the Inflation Reduction Act provision itself — but there is no mechanism to collect it for the foreseeable future.
Greenhouse gas reporting is slated for a long delay. In September 2025, EPA proposed to push Subpart W reporting for the oil and gas sector all the way to 2034. Notably, industry groups including the American Petroleum Institute and the U.S. Chamber of Commerce filed comments opposing a full rescission, arguing that a stable federal reporting framework is preferable to a patchwork of state programs and supports U.S. competitiveness in markets that increasingly demand verified low-methane gas.
Enforcement was deprioritized early. In March 2025, EPA’s enforcement office issued guidance stating that compliance efforts would no longer focus on methane emissions from oil and gas facilities, and that enforcement actions should not shut down energy production absent an imminent threat to health or an express legal requirement.
Compliance deadlines for the core standards were extended. Through an interim final rule in July 2025 and a final rule in late 2025, EPA pushed back deadlines for several OOOOb/OOOOc provisions — including net heating value monitoring for flares, the zero-emission standard for process controllers, certain closed-vent-system and storage-vessel requirements, the super-emitter program, and the date for states to submit existing-source plans.
The standards themselves are being loosened. In April 2026, EPA finalized a rule revising two technical aspects of the 2024 standards — expanding the allowable duration of temporary flaring of associated gas and significantly reducing net-heating-value monitoring requirements for flares and combustion devices. Analysts noted that the final rule cut stringency even beyond what EPA had originally proposed. EPA estimated the change would save the industry about $2.5 billion through 2038.
A broader reconsideration is coming. EPA announced in March 2025 that it would undertake a comprehensive reconsideration of the entire OOOOb/OOOOc framework, and has signaled additional proposed amendments are in development. The April 2026 rule was explicitly framed as a “first step.”
The legal foundation is under attack. The most consequential move may be the August 2025 proposal to rescind EPA’s 2009 Endangerment Finding — the scientific determination that greenhouse gases threaten public health and welfare, which is the legal basis for regulating them under the Clean Air Act. If EPA finalizes that rescission and courts uphold it, it would not merely roll back the current methane rules; it would strip future administrations of the authority to regulate greenhouse gases under the Act at all.
What Is Still in Force
Despite the rollbacks, it would be a mistake to conclude that operators face no obligations. Most provisions of the 2024 standards remain legally in effect — only specific compliance deadlines were extended, and only the provisions explicitly listed in the extension rules were delayed. Leak detection and repair requirements, equipment standards, and reporting obligations not specifically deferred continue to apply. The flaring compliance deadline, for instance, fell in May 2026, and EPA issued guidance reminding operators of the standards even as it reaffirmed its intent to roll them back.
The picture is further complicated by states. California, New Mexico, Colorado, and others maintain their own methane rules, and some are tightening as federal enforcement loosens. State-level interpretation and implementation of the OOOO-series rules means operators with assets across multiple basins cannot rely on the federal posture alone. The practical upshot, as compliance advisors have put it, is that methane planning has not stopped — it has gotten more complicated.
The Litigation Layer
Almost every step has been challenged in court. Industry groups and Republican-led states sued over the 2024 standards; environmental groups sued over the 2025 deadline extensions, arguing EPA skipped required notice-and-comment procedures; and environmental organizations have petitioned for review of the rollback actions. The Supreme Court declined in 2024 to stay the existing-source standards. The endangerment-finding rescission, if finalized, will almost certainly trigger litigation that could reach the Supreme Court and determine the long-term scope of federal climate authority.
Why It Matters
The stakes extend beyond any single rule. Methane’s short atmospheric lifetime is exactly what makes it valuable to regulate: cuts made now slow warming quickly. The gas wasted through leaks and flaring is also, literally, salable product — a point even some industry participants make when arguing that reduction can be cost-effective rather than purely burdensome.
The deeper question raised by the 2025–2026 actions is structural. Periodic reversals of specific rules are a familiar feature of U.S. environmental policy, and a future administration could rebuild the standards much as the Biden administration rebuilt them after 2021. But rescinding the endangerment finding would be different in kind — an attempt to remove the legal ground on which any future methane rule would have to stand. Whether that succeeds is the question that will shape federal methane policy well beyond this decade.
This article reflects regulatory developments through mid-2026. Because the rules are actively changing and several actions are in litigation, anyone with compliance obligations should consult current EPA guidance and qualified legal counsel rather than relying on a summary.
