The bill amends Internal Revenue Code section 45Q to create a new mine methane capture incentive credit. It extends the existing carbon‑capture tax framework to methane emitted from mining activities by adding a dedicated paragraph that treats captured methane as a creditable greenhouse‑gas reduction on a per‑metric‑ton CO2e basis.
The amendment defines which methane counts, what equipment qualifies, where the captured methane must go or how it must be used, and sets technical and size thresholds for eligible projects (including a 2,500 metric‑ton CO2e annual capture minimum and a construction start cutoff). The rule design favors projects that inject methane into regulated pipelines or use it in controlled energy applications, and the credit applies to methane captured after December 31, 2024.
At a Glance
What It Does
The bill inserts a new paragraph into §45Q that treats ‘‘qualified methane’’ captured at mining sources as eligible for the 45Q per‑metric‑ton tax credit, substituting methane‑specific terms where §45Q previously referenced carbon oxide. It requires measurement at the capture source and verification at the point of injection or use, and ties eligibility to specific uses or pipeline standards.
Who It Affects
Operators and owners of underground, surface, and abandoned mines who capture methane; companies that build or operate capture equipment and gathering systems; pipeline owners and utilities that receive and transport the gas; tax equity investors and firms that advise on 45Q claims.
Why It Matters
It creates a direct federal tax incentive to monetize mine methane reductions, potentially unlocking investment in capture infrastructure at mines that can meet the technical rules. The design choices—pipeline integrity requirements, capture thresholds, and verification points—will determine which projects can realistically access the credit and how developers structure deals and financing.

What This Bill Actually Does
The bill does not create a new separate tax program; it extends the existing §45Q credit to methane captured from mining activities by adding a mine‑methane specific paragraph. Rather than inventing a new rate or mechanic, it tells the tax code to treat ‘‘qualified methane’’ on the same per‑metric‑ton CO2e basis used for carbon capture, but substitutes methane‑oriented terminology and eligibility rules.
That means taxpayers will claim a 45Q credit calculated per metric ton of CO2e equivalent of methane captured, subject to the same broader §45Q framework unless explicitly modified.
To be eligible, methane must be captured from mining activities (including underground, surface, and abandoned or closed mines) and measured at the source. The bill insists on verification at the point where the methane is injected or used, which shifts attention to metering and recordkeeping at both the capture site and downstream connection.
It defines ‘‘methane capture equipment’’ narrowly as the hardware that connects the mine source to either a pipeline system or energy generation equipment, so the credit hinges on achieving an end use or injection pathway that meets the statute’s conditions.The statute sets several practical gates. A ‘‘qualified facility’’ is an individual capture source (borehole, well, vent shaft) where construction begins before January 1, 2036, methane capture equipment construction also begins before that date, and the source captures at least 2,500 metric tons CO2e of methane in a taxable year.
Acceptable uses are limited: the methane can be injected into pipelines that comply with DOT pipeline integrity standards (49 C.F.R. §192) and specified leak‑monitoring rules, into gathering systems that feed such pipelines, or used to produce heat or other energy so long as releases to atmosphere are no more than de‑minimis. The bill explicitly replaces references to enhanced oil recovery with these methane end‑use pathways.Finally, the amendment is retroactive to captures after December 31, 2024.
That effective date matters for project timing, tax planning, and any pre‑existing capture operations that might now qualify; however, the construction‑start cutoff and the 2,500 metric‑ton floor will limit eligibility to reasonably large or fast‑moving projects. Implementation will require IRS guidance on measurement standards, allocation rules when multiple parties participate in a capture‑to‑market chain, and interaction with state pipeline and air regulations.
The Five Things You Need to Know
The bill adds a methane‑specific paragraph to §45Q so captured mine methane is eligible for the 45Q per‑metric‑ton CO2e tax credit, using the CO2e definition in §45Z(d)(2).
A ‘‘qualified facility’’ must begin construction (the facility and its methane capture equipment) before January 1, 2036 and capture at least 2,500 metric tons CO2e of methane during the taxable year to qualify. , Eligible uses are limited to injection into pipelines that comply with 49 C.F.R. §192 integrity rules (and related leak‑monitoring provisions), gathering systems that feed such pipelines, or controlled energy uses that involve no more than de‑minimis methane release. , The bill requires methane to be measured at the capture source and verified at the point of injection or utilization, putting metering and verification obligations on both capture site operators and receiving systems. , The amendment applies to methane captured after December 31, 2024, making recently installed capture systems potentially retroactively eligible if they meet the other statutory tests.

Short title
Provides the act’s name: ‘‘Methane Reduction and Economic Growth Act.’
Adds a mine‑methane paragraph to §45Q(f)
Inserts paragraph (10) into §45Q(f), establishing ‘‘methane capture’’ as an eligible activity by directing the tax code to treat qualified methane like qualified carbon oxide for per‑metric‑ton crediting while substituting methane‑specific terms. The change cross‑references existing §45Q machinery (credit calculation, transfer/claim rules, recapture rules where applicable) except where the new paragraph explicitly amends particular subsections.
Eligible uses and technical compliance for captured methane
Specifies two broad categories of acceptable end uses: (1) injection by the taxpayer into pipelines that meet DOT pipeline integrity management standards (49 C.F.R. §192) and certain leak‑monitoring provisions, or into gathering systems that feed such pipelines; and (2) controlled uses for producing heat or energy with only de‑minimis atmospheric release. This is a practical gate: projects that cannot establish a compliant downstream pathway or that vent methane will not qualify.
Qualified facility, thresholds, and measurement rules
Defines ‘‘qualified facility’’ as an identifiable capture source (borehole, well, vent shaft) where construction (of the facility and methane capture equipment) begins before January 1, 2036, and that captures at least 2,500 metric tons CO2e of methane in a taxable year. It also defines ‘‘qualified methane’’ and requires measurement at the capture source with verification at injection/use, and defines ‘‘methane capture equipment’’ as the hardware linking source to pipeline or energy equipment—placing clear responsibility on project developers for metering and equipment selection.
Effective date
States the amendments apply to qualified methane captured after December 31, 2024. That makes projects that began operations in early 2025 potentially eligible, subject to meeting the statute’s capture volume and construction‑start criteria.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Mine operators and owners (including projects at active, closed, or abandoned mines) — The credit creates a monetizable revenue stream for methane capture projects that meet the pipeline or controlled‑use rules, improving project economics for larger mines and those with access to downstream buyers.
- Investors and tax‑equity providers — The familiar §45Q structure makes the credit deployable into tax‑equity financing models, offering an income stream tied to measurable tons CO2e captured.
- Pipeline and energy‑offtake companies — Companies that can accept mine methane into compliant pipelines or use it for heat‑or‑power generation gain new feedstock opportunities and commercial incentives to build gathering and conditioning capacity.
- Equipment vendors and engineering firms — Demand for methane collection, metering, conditioning, and connection equipment will rise where projects seek to meet the statute’s technical gates.
Who Bears the Cost
- Mine operators (especially small operations) — They must install capture equipment, build connections to compliant pipelines or energy systems, and implement source and injection metering; projects below the 2,500 MT CO2e floor likely cannot recoup these upfront costs.
- Pipeline owners/operators and utilities — Receiving systems must comply with DOT §192 integrity and leak‑monitoring standards for the credit to apply, potentially requiring additional monitoring, inspection, or contractual assurances.
- IRS and Treasury (administration and enforcement) — The agency will face administrative burdens to develop guidance, handle verification disputes, and audit technical claims, and the Treasury forgoes revenue equal to claimed credits (the fiscal cost depends on uptake).
Key Issues
The Core Tension
The bill balances environmental integrity against practical access: tight technical rules (metering, DOT pipeline standards, a 2,500‑metric‑ton floor, and construction‑start deadlines) protect against weak or easily gamed credits but favor larger, better‑funded operators—potentially leaving smaller or legacy‑site projects, which could still reduce emissions locally, without access to federal support.
Several implementation challenges and trade‑offs are embedded in the bill’s language. First, the measurement and verification rule—measure at the capture source and verify at point of injection or use—creates a two‑node compliance chain that will require harmonized metering standards and clear allocation rules when multiple entities touch the gas.
The statute leaves technical specifics to IRS guidance, and without standardized testing and verification protocols there is risk of inconsistent treatment, disputes over quantity or CO2e conversion, and audit exposure.
Second, the 2,500 metric‑ton CO2e annual threshold and the construction‑start cutoff (before January 1, 2036) concentrate benefits on larger or well‑financed projects. That reduces administrative complexity and limits small‑scale, high‑cost projects that may have negligible climate impact, but it also excludes many community or orphan‑mine projects where capture could be locally beneficial.
The pipeline integrity and leak‑monitoring conditions assure environmental integrity but raise practical barriers where pipelines or gathering systems do not exist or where operators cannot meet DOT contractual or technical requirements.
Finally, the bill’s reliance on the existing §45Q framework raises familiar questions: how credits are allocated among owners and contractors; whether capture projects can double‑count reductions in voluntary carbon markets or state compliance programs; and how the credit interacts with state permitting, methane regulation, or operator liability. These unresolved implementation items will determine whether the credit translates quickly into operational capture projects or remains legally and administratively hard to deploy.
