S 147 establishes a federal grant program to help communities create accessible clean air centers and provide free, certified air filters to low-income households with vulnerable members (such as seniors, people with asthma, or disabilities) during wildfire smoke events. Local air pollution agencies receive grants to partner with community groups, set up clean air centers in smoke-prone areas, and distribute at least 1,000 certified air filters per program to eligible households - along with filter replacements - at no cost. The program requires educational materials on filter use, post-distribution surveys to assess effectiveness, and annual reports to Congress on implementation and outcomes. This directly supports households at high health risk from wildfire smoke in underserved communities.
HR 346, the Preserving Choice in Vehicle Purchases Act, amends the Clean Air Act to clarify that state emissions standards directly or indirectly limiting sales of new internal combustion engine vehicles (ICE) would not qualify for federal EPA waivers. It adds a specific definition to the law, requiring states to avoid restrictions on ICE vehicle sales to maintain waiver eligibility. The bill also mandates the EPA to revoke existing waivers granted between January 2022 and the bill's enactment if those waivers didn't comply with the new definition. This directly affects states with their own vehicle emission standards (like California), the EPA's waiver approval process, and automakers selling vehicles in those states.
Closing Loopholes for Oil and other Sources of Emissions Act or the CLOSE Act This bill amends the Clean Air Act to revise requirements for hazardous air pollutants. Specifically, the bill allows (1) emissions from oil or gas exploration or production wells and emissions from pipeline compressors or pump stations to be aggregated with emissions from other similar sources and regulated as a major source of toxic air pollutants, (2) emissions from those wells to be aggregated for purposes of emissions standards for hazardous air pollutants, and (3) emissions from oil or gas production wells to be regulated as an area source of toxic air pollutants. The Environmental Protection Agency must (1) issue a final rule adding hydrogen sulfide to the list of hazardous air pollutants; and (2) revise the list of air pollution sources within 365 days after issuing the rule to include categories and subcategories of major sources and area sources of hydrogen sulfide, including oil and gas wells.
This bill would cancel a specific Environmental Protection Agency (EPA) rule finalized in March 2024 that reconsidered national air quality standards for particulate matter. It directly affects the EPA’s regulatory authority and would prevent the implementation of that rule, impacting industries and communities subject to particulate matter air quality standards. The key mechanism is a direct nullification of the EPA’s final rule (89 Fed. Reg. 16202), declaring it "shall have no force or effect." This policy change would revert to prior air quality standards without altering the broader regulatory framework.
This bill amends the Clean Air Act to update the definition of fossil fuel, explicitly including "fuel for ocean-going vessels" alongside home heating oil and jet fuel. It directly affects the shipping industry by requiring the Environmental Protection Agency (EPA) to issue regulations within one year of enactment to implement this updated definition. The key mechanism is changing the statutory definition to ensure ocean vessel fuels are covered under existing fossil fuel regulations, potentially influencing future clean fuel standards for ships. The EPA must also submit a report to Congress on implementation within one year of finalizing these regulations.
The Clean Cloud Act of 2025 requires data centers and cryptocurrency mining facilities with more than 100 kilowatts of power to annually report their energy consumption and sources to the Environmental Protection Agency. The bill establishes regional greenhouse gas emissions baselines that decrease by 11% each year from 2026 through 2034, with fees assessed on facilities and utilities when their energy use exceeds these baselines. Fees start at $20 per kilowatt-hour above the baseline in 2026, increasing annually with inflation, and funds collected will support program administration, lower residential energy costs, and clean energy projects like zero-carbon power generation. This law directly affects data centers, cryptocurrency mining facilities, and the electric utilities that serve them, aiming to increase transparency about energy sources and reduce carbon emissions from these energy-intensive operations.
HR 4994, the Safe Air on Airplanes Act, requires the Federal Aviation Administration to update regulations to phase out bleed air systems in aircraft. It prohibits new aircraft designs from using these systems, mandates filters to remove oil fumes in new aircraft by 2031 (7 years after enactment), and sets a 30-year phase-out schedule for existing aircraft designs (25% without bleed air by 2031, 50% by 2041, 100% by 2051). The bill directly affects aircraft manufacturers and airlines, as it changes requirements for cabin air systems that pull engine air for ventilation. These changes focus on modifying manufacturing standards and air quality systems in turbine and turbo-prop aircraft.
HR 2218 (Stop CARB Act of 2025) would block California from enforcing its own emissions standards for construction equipment, farm machinery, and locomotives by repealing federal provisions that allow states to set stricter rules. It specifically repeals Section 177 of the Clean Air Act, which authorizes California’s vehicle standards, and invalidates all existing waivers permitting California’s regulations (including those for nonroad engines) upon enactment. The bill also denies any pending waiver applications and removes references to California’s standards from other Clean Air Act sections. This directly affects California’s regulatory authority over emissions for these specific equipment types and vehicle categories.
This bill establishes a tax on imported oil and natural gas based on the methane emissions from their production in the exporting country. The tax amount is calculated using the same emissions charges that would apply to U.S. producers under Clean Air Act rules, scaled to the volume of the imported product. It aims to incentivize foreign producers to reduce methane emissions by making high-emission imports more expensive, while giving U.S. producers with lower emissions a competitive advantage. The tax would apply to imports after December 31, 2025, and includes provisions for international cooperation to align methane standards globally.
S 173 increases taxes on aviation fuel used by private jets and non-commercial aircraft, imposing a rate of 35.9 cents plus $1.641 per gallon (compared to 4.3 cents for commercial aviation), with annual inflation adjustments starting in 2026. It creates exceptions for emergency uses like medical evacuations or disaster response, and eliminates an existing exemption for certain agricultural aviation. The additional tax revenue funds a new "Clean Communities Trust Fund" to support air quality monitoring, expand public transit infrastructure near airports, and improve transportation in disadvantaged communities - requiring at least 50% of funds to target areas disproportionately impacted by air pollution. This bill directly affects private jet operators and aviation fuel suppliers while directing resources to environmental and transit projects in low-income communities.
