H.R.1 – One Big Beautiful Bill Act (Public Law 119-21, enacted July 4, 2025)

The reconciliation package that systematically unwinds Inflation Reduction Act climate spending and tax incentives while expanding fossil-fuel leasing. Below are the sections that directly touch green/renewable technology, fuels, and climate policy.

---

1. Buildings, housing, and efficiency

Sec. 30002 – Recission of funds for Green and Resilient Retrofit Program for Multifamily Housing

• Explanation: It claws back unobligated IRA balances for HUD's program that funded energy-efficiency, electrification, and resilience upgrades in affordable multifamily properties. The program was designed to cut energy use ~25% and GHG emissions ~50% in low-income housing.
• Impact: It stops federal capital for decarbonizing affordable housing, likely raising tenant utility costs and heat/flood vulnerability. It also removes a major demand pull for heat pumps, solar, and low-carbon building materials in that market.

Sec. 60020 – Recission for Federal Buildings Fund conversion to high-performance green buildings Sec. 60021 – Recission for low-carbon materials for Federal buildings Sec. 60022 – Recission for GSA emerging sustainable technologies

• Explanation: These three sections rescind IRA money that would have converted GSA facilities to high-performance green buildings and purchased low-embodied-carbon concrete, steel, and glass. They also end GSA's emerging-technologies deployment program.
• Impact: Federal construction will no longer be required to prioritize low-carbon procurement, weakening market signals for domestic clean-materials manufacturers. It also slows energy-use reductions in the government's own building portfolio.

Sec. 70505 – Termination of energy efficient home improvement credit Sec. 70506 – Termination of residential clean energy credit Sec. 70507 – Termination of energy efficient commercial buildings deduction Sec. 70508 – Termination of new energy efficient home credit

• Explanation: The sections end the 25C, 25D, 179D, and 45L credits. Homeowners can claim up to $3,200 for insulation, heat pumps, etc., and up to 30% for rooftop solar, only for property placed in service before 2026; commercial and new-home incentives end mid-2026 to mid-2027.
• Impact: It removes the primary federal incentive for residential solar, battery storage, and heat-pump adoption after 2025. Builders and retrofitters will face reduced demand, likely slowing residential electrification.

2. Vehicles and transportation fuels

Sec. 60001 – Recission for clean heavy-duty vehicles

• Explanation: It rescinds EPA grants and rebates to replace school buses, garbage trucks, and other medium/heavy-duty vehicles with zero-emission models in nonattainment and disadvantaged communities.
• Impact: It halts a key federal pathway for fleet electrification where diesel pollution is highest. School districts and municipalities will lose funding that offset the upfront cost premium of electric buses and trucks.

Sec. 70501 – Termination of previously-owned clean vehicle credit Sec. 70502 – Termination of clean vehicle credit Sec. 70503 – Termination of qualified commercial clean vehicles credit Sec. 70504 – Termination of alternative fuel vehicle refueling property credit

• Explanation: Credits of up to $4,000 for used EVs, $7,500 for new EVs, and up to $40,000 for commercial clean vehicles end for purchases after September 30, 2025. The 30C credit for chargers and hydrogen/CNG stations ends for property placed in service after June 30, 2026.
• Impact: It eliminates the federal price support that drove EV adoption since 2022, raising effective purchase prices overnight. Charging-infrastructure deployment will also slow as private investment loses the 30% cost offset.

Sec. 40006 – Corporate average fuel economy civil penalties Sec. 40010 – Treatment of unobligated funds for alternative fuel and low-emission aviation technology

• Explanation: Sec. 40006 revises CAFE penalty structures, reducing financial exposure for automakers missing fuel-economy targets. Sec. 40010 redirects unobligated IRA aviation funds away from sustainable aviation fuel and low-emission technology.
• Impact: Weaker penalties reduce the regulatory push for higher MPG and EV sales mixes. Aviation decarbonization loses dedicated federal R&D money, delaying SAF scale-up.

Sec. 70521 – Extension and modification of clean fuel production credit

• Explanation: It extends the 45Z credit through 2029 but limits feedstocks to North America, excludes indirect land-use emissions from lifecycle calculations, and requires distinct rates for manure-based fuels.
• Impact: It preserves a subsidy for domestic biofuels and renewable diesel while loosening GHG accounting. It favors agricultural feedstocks but may increase lifecycle emissions compared to prior IRA methodology.

3. Power sector – wind, solar, storage, nuclear, hydrogen

Sec. 70512 – Termination and restrictions on clean electricity production credit (45Y) Sec. 70513 – Termination and restrictions on clean electricity investment credit (48E) Sec. 70509 – Termination of 5-year MACRS for solar/wind Sec. 70514 – Phase-out of advanced manufacturing production credit for wind components

• Explanation: 45Y and 48E are terminated for wind and solar facilities placed in service after December 31, 2027, and disallowed for leased residential systems. The special 5-year depreciation for solar/wind ends for construction starting after 2024. The 45X credit for wind turbine components ends after 2027.
• Impact: It removes the technology-neutral credits that replaced the ITC/PTC, effectively sunsetting federal support for new utility-scale wind and solar by 2028. Domestic wind manufacturing loses its production incentive, likely shifting supply chains overseas.

Sec. 70511 – Termination of clean hydrogen production credit

• Explanation: The 45V hydrogen credit is allowed only for facilities beginning construction before January 1, 2028, instead of 2033 under prior law.
• Impact: It shortens the investment window for green and blue hydrogen by five years, likely stranding projects in development. It signals reduced federal backing for hydrogen as a decarbonization pathway.

Sec. 70510 – Modifications of zero-emission nuclear power production credit

• Explanation: It bars the 45U nuclear credit for facilities owned or influenced by certain foreign entities.
• Impact: It preserves the credit for domestic nuclear but adds national-security screens. It does not terminate nuclear support, unlike wind/solar.

4. Industrial decarbonization and carbon management

Sec. 60006 – Recission for low emissions electricity program

Sec. 60007 – Recission for Renewable Fuel Standard GHG data

Sec. 60015 – Recission for low-embodied carbon labeling

Sec. 60024 – Recission of low-carbon transportation materials grants

• Explanation: These sections rescind EPA and FHWA programs that provided education, technical assistance, and grants to reduce power-sector emissions, improve lifecycle GHG accounting for fuels, label low-carbon construction materials, and fund low-carbon asphalt/concrete for highways.
• Impact: They eliminate federal tools for measuring and procuring lower-carbon industrial products. State DOTs and manufacturers lose incentives to decarbonize cement, steel, and asphalt.

Sec. 70522 – Restrictions on carbon oxide sequestration credit

• Explanation: It raises the 45Q credit to $17 per ton for CO2 used in enhanced oil recovery or other utilization, equalizing it with geologic storage, and bars foreign-influenced entities.
• Impact: It increases the value of carbon capture when paired with oil production while maintaining support for storage. It tilts CCUS economics toward EOR rather than pure sequestration.

5. Methane, air pollution, and climate programs

Sec. 60002 – Repeal of Greenhouse Gas Reduction Fund

• Explanation: It repeals the $27 billion green bank that provided low-cost financing for clean energy and GHG-reduction projects in low-income and disadvantaged communities.
• Impact: It eliminates the largest federal climate-finance vehicle, cutting off capital for community solar, efficiency, and resilience projects. Private leverage expected from the fund will not materialize.

Sec. 60003 – Recission for diesel emissions reductions

Sec. 60004 – Recission for air pollution monitoring

Sec. 60005 – Recission for schools air pollution

• Explanation: They rescind EPA DERA grants, national air-quality monitoring expansion, methane monitoring, and school-based pollution reduction grants.
• Impact: Communities lose funding to replace diesel engines and to deploy sensors in environmental-justice areas. Federal capacity to track methane and air toxics is reduced.

Sec. 60012 – Recission for methane emissions and waste reduction incentive program

• Explanation: It rescinds funding for EPA incentives to monitor and cut methane from oil and gas systems and postpones the IRA methane fee on excess emissions until 2034.
• Impact: It defers the primary federal price on methane leaks for a decade and removes grants for leak detection. It reduces the economic case for rapid methane abatement.

Sec. 60013 – Recission for greenhouse gas air pollution plans Sec. 60010 – Recission for greenhouse gas corporate reporting Sec. 60016 – Recission for environmental and climate justice block grants Sec. 60018 – Recission for environmental and climate data collection

• Explanation: These rescind EPA Climate Pollution Reduction Grants to states/tribes, corporate climate-disclosure support, EJ block grants, and CEQ data-collection for cumulative impacts mapping.
• Impact: State and local climate planning loses its IRA funding backbone. Transparency on corporate emissions and EJ burdens declines, limiting accountability.

6. Fossil-fuel leasing and financing expansion

Sec. 50101 – Onshore oil and gas leasing Sec. 50102 – Offshore oil and gas leasing Sec. 50103 – Royalties on extracted methane Sec. 50104 – Alaska oil and gas leasing (ANWR) Sec. 50105 – National Petroleum Reserve-Alaska Sec. 50201-50204 – Coal leasing

• Explanation: The sections mandate quarterly onshore lease sales, require at least 30 offshore sales in the Gulf and Cook Inlet, lower offshore royalty rates, end royalties on vented/flared gas, mandate four ANWR lease sales and five NPR-A sales within 10 years, and force issuance of pending coal leases while cutting federal coal royalties.
• Impact: They lock in expanded federal fossil-fuel supply through 2034, increasing long-term production potential. Lower royalties and eliminated methane charges improve economics for oil, gas, and coal operators.

Sec. 50403 – Energy dominance financing

• Explanation: It revises DOE's Title 17 financing to eliminate eligibility for projects that avoid or reduce GHGs, removes emissions-control requirements for fossil projects, and adds $1 billion for critical minerals and grid-reliability projects.
• Impact: Federal loan guarantees shift from clean-energy deployment to fossil and mineral supply projects. It explicitly deprioritizes decarbonization as a financing criterion.

Sec. 50302 – Renewable energy fees on Federal land Sec. 50303 – Renewable energy revenue sharing

• Explanation: They codify annual acreage rent for wind/solar rights-of-way on BLM land and create revenue-sharing with states/counties.
• Impact: They provide fiscal certainty for renewables on public lands but add a new cost layer, potentially raising project costs while incentivizing local support.

Final ruling

Taken together, H.R.1 does not merely trim climate spending; it structurally reverses the IRA framework by terminating consumer and business tax credits for EVs, rooftop solar, heat pumps, and efficiency by 2025-2027, ending 45Y/48E support for new wind and solar after 2027, repealing the $27 billion Greenhouse Gas Reduction Fund and dozens of EPA/DOE grant programs, postponing methane fees to 2034, and simultaneously mandating expanded onshore, offshore, ANWR, NPR-A, and coal leasing with lower royalties. The bill preserves and modestly expands support for hydrogen storage, carbon capture tied to oil recovery, nuclear, geothermal, hydropower, and North American biofuels, but the net policy shift moves federal energy strategy from emissions reduction to production maximization, which independent analyses project will raise U.S. GHG emissions 8-12% above IRA-baseline by 2035.
