This bill amends section 45Q of the Internal Revenue Code to allow a per‑metric‑ton CO2e tax credit for methane captured from mining activities. It adapts 45Q’s mechanics—crediting per metric ton of CO2e and the existing administrative framework—to mine methane captured and put to energy use or otherwise utilized without significant release.
The change makes mine methane capture a tax‑credit‑eligible activity under federal law, broadening 45Q beyond carbon dioxide and engineered CO2 storage. The provision targets emissions from active, abandoned, and surface mines and establishes measurement and delivery requirements that will shape project design, verification, and midstream connections.
At a Glance
What It Does
Adds a new paragraph to section 45Q to apply 45Q’s per‑ton credit structure to 'qualified methane' captured at mining sites and delivered for energy use or utilization, and defines the equipment and facilities that qualify.
Who It Affects
Mine operators, methane capture project developers, midstream pipeline and gathering operators, energy generators that combust or inject captured methane, and taxpaying entities claiming 45Q credits.
Why It Matters
The bill creates a federal incentive that could make mine‑methane projects financially viable, shift investment toward capture infrastructure at mines (including abandoned sites), and require new measurement, verification, and compliance connections to regulated pipeline systems.

What This Bill Actually Does
The bill inserts a dedicated 'Methane Capture' paragraph into section 45Q, so taxpayers can claim the existing 45Q credit on a per‑metric‑ton CO2e basis for methane captured at mining operations. It repurposes 45Q’s structure—normally applied to carbon oxide—by substituting 'methane capture' terminology and CO2e measurement units where appropriate.
The credit applies when the methane is either injected for energy use in a compliant pipeline or gathering system, or used directly for heat or energy with only de‑minimis atmospheric release.
A 'qualified facility' under the bill is an individual methane source at a mining site (for example, a borehole, well, or vent shaft). To qualify, construction of the facility or of the methane capture equipment must begin before January 1, 2036, and the facility must capture at least 2,500 metric tons CO2e of methane in a taxable year.
The bill requires source‑level measurement and verification, with verification at the point of injection or utilization, linking the credit to traceable, auditable emission reductions.The bill also ties injection eligibility to pipeline and gathering systems that comply with certain integrity and leak‑monitoring requirements in federal pipeline safety regulations. By defining 'methane capture equipment' as equipment that connects a qualified facility to an existing or new pipeline or to energy generation equipment, the text effectively nudges projects toward physical interconnection with midstream or on‑site energy use rather than venting or flaring.Finally, the legislation is retroactively effective for qualified methane captured after December 31, 2024.
Practically, that means projects already capturing methane in 2025 may be eligible if they meet the bill’s measurement, utilization, and verification rules, and if construction of relevant equipment commenced before the 2036 cutoff.
The Five Things You Need to Know
The bill adds paragraph (10) to 45Q(f), expressly extending 45Q’s per‑metric‑ton CO2e credit framework to 'qualified methane' captured from mining activities.
To qualify, a 'qualified facility' must begin construction (of the facility or methane capture equipment) before January 1, 2036 and capture at least 2,500 metric tons CO2e of methane during a taxable year.
Credit eligibility requires that captured methane be injected for energy use into a pipeline or gathering system that meets federal pipeline integrity and leak‑monitoring requirements, or be used for heating/energy with no more than de‑minimis methane release.
The bill mandates source‑level measurement of methane and verification at the point of injection or utilization as a condition for claiming the credit.
The amendments apply to qualified methane captured after December 31, 2024, creating retroactive applicability for captures occurring in 2025.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act’s short title: 'Methane Reduction and Economic Growth Act.' This is purely formal and does not change substantive rules, but the title signals the bill’s dual intent of emissions reduction and economic stimulus for capture projects.
Creates a 'Methane Capture' paragraph in 45Q
Adds a new paragraph (10) to 45Q(f) making mine‑sourced methane eligible for the 45Q credit by substituting methane terms and CO2e units into the existing statute. Mechanically, this means the statutory per‑ton credit calculation and many administrative provisions of 45Q are available for methane capture projects once the other bill conditions are met.
Specifies eligible uses and delivery routes for captured methane
Sets out three mutually exclusive paths for eligible utilization: injection into a pipeline meeting specific integrity and leak‑monitoring standards, injection via a gathering system that feeds such a pipeline, or direct use for heat/energy so long as methane release is no more than de‑minimis. This provision ties tax eligibility to real, usable energy offtake rather than uncontrolled releases.
Defines 'qualified facility', applies capture thresholds, and updates cross‑references
Defines an eligible 'individual source' (borehole, well, vent shaft) and imposes a minimum annual capture threshold (2,500 metric tons CO2e). It requires substitution of methane language across related 45Q subsections and adjusts statutory mechanics that previously referenced capture capacity to instead reference historic captured amounts.
Retroactivity to calendar year 2025
Specifies the amendments apply to qualified methane captured after December 31, 2024. The retroactive start means captures occurring in 2025 can qualify provided projects meet the statutory construction and measurement/verification conditions.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Mine operators that can deploy capture systems: The credit makes otherwise marginal capture installations potentially economic, particularly at sites with persistent methane emissions (active or abandoned).
- Project developers and EPC firms building methane capture systems: Demand for capture equipment, interconnection work, and measurement/verification services should increase.
- Energy generators and aggregators that accept or use captured methane: Facilities that combust or inject mine methane get access to new fuel streams and can partner with project owners to monetize credits.
- Communities near methane‑emitting mines: Reduced fugitive emissions can improve local air quality and lower greenhouse‑gas footprints, delivering public health and environmental benefits.
- Taxpayers or investors purchasing 45Q credits via tax equity structures: The expanded eligible project set creates new investment opportunities for tax equity markets familiar with 45Q transactions.
Who Bears the Cost
- Mine operators required to install capture equipment and pay upfront capital and operating costs: Projects must meet construction, interconnection, measurement, and verification requirements before claiming credits.
- Midstream pipeline and gathering operators facing interconnection and compliance burdens: Pipeline integrity and leak‑monitoring obligations are prerequisites for some eligible pathways and could require upgrades or contractual obligations.
- IRS and federal agencies responsible for verification and administration: The statute’s measurement and point‑of‑injection verification requirements will create new compliance and audit workloads for tax authorities.
- Smaller mines and diffuse sources excluded by the 2,500 mt CO2e threshold: These sites will not qualify and may need different, non‑tax policy supports to address emissions.
- Potential downstream purchasers if credits depress market prices for capture services: Market shifts could redistribute value from capture operators to larger, credit‑oriented investors.
Key Issues
The Core Tension
The bill balances two legitimate goals—rapidly reducing high‑global‑warming‑potential methane emissions from mines and incentivizing economically viable capture projects—against the risk that subsidizing captured methane as an energy commodity may lock that methane into continued combustion and fossil‑fuel markets; the central dilemma is how to design a tax incentive that reliably yields net climate benefits without simply subsidizing additional usable fossil gas.
The bill’s core mechanics look simple: fold mine methane into 45Q. In practice, enactment will raise several implementation questions.
First, the statute requires source‑level measurement and verification at the point of injection or use, but it does not create a new federal measurement standard or designate a certifying body; IRS guidance and interagency rulemaking will be necessary to define acceptable measurement technologies, frequency of verification, and audit trails. That gap creates short‑term uncertainty for project developers deciding what monitoring investments are sufficient.
Second, the delivery conditions (pipeline integrity and leak‑monitoring compliance) tie tax eligibility to pipeline safety rules and to the practical availability of pipeline or gathering interconnection. Many mine sites—especially remote or small operations—lack nearby pipeline infrastructure, so projects may face high interconnection capex that the credit may or may not offset.
The 2,500 metric‑ton CO2e annual capture threshold and the 2036 'construction‑begins' cutoff create a clear economic floor and a timeline that favors larger, well‑capitalized projects and may encourage a near‑term rush to begin construction.
Finally, the bill boosts the economic value of captured methane but does not address lifecycle implications: captured methane used as fuel still results in CO2 emissions when combusted, and making more methane available to energy markets can extend fossil fuel use unless coupled with parallel policy goals (e.g., displacing higher‑emission fuels or pairing with electrification). Ensuring that credits represent genuine and additional climate benefits will depend on tight verification, clear baselines, and careful IRS/agency guidance about double‑counting and credit stacking with other programs.
