The bill, titled the "MARKET CHOICE Act," introduces a new subtitle to the Internal Revenue Code imposing a tax on domestic greenhouse gas emissions. This tax applies to combusted fossil fuels, emissions from specified industrial processes, and certain product uses, starting at $35 per metric ton of carbon dioxide equivalent in 2027 and increasing annually. Exemptions are provided for noncombustive uses and for carbon capture and storage, with specific regulations to be established by the Secretary and Administrator. To prevent carbon leakage and encourage global emission reduction, the bill establishes a border greenhouse gas adjustment mechanism. This mechanism levies a tax on imported greenhouse gas-intensive products and provides rebates for exported domestic products, ensuring consistency with international agreements. The Secretary of the Treasury, in consultation with the Commissioner, is tasked with establishing the methodology and procedures for these adjustments. A significant portion of the revenue generated from the new carbon tax, specifically 75%, will be deposited into the newly created Rebuilding Infrastructure and Solutions for the Environment Trust Fund (RISE Trust Fund) . From this fund, 70% of the amounts are appropriated to the Highway Trust Fund for infrastructure improvements. Additionally, 10% is allocated for annual State grants to eligible low-income households, distributed based on each state's contribution to total United States greenhouse gas emissions. Further allocations from the RISE Trust Fund include funding for weatherization programs, assistance for displaced energy workers, the Airport and Airway Trust Fund, the Leaking Underground Storage Tank Trust Fund, and the Abandoned Mine Reclamation Fund. Significant portions are also directed towards coastal flooding mitigation, Advanced Research Projects Agency-Energy (ARPA-E), carbon capture and removal research and development, energy storage research, reforestation, and agricultural conservation programs. The bill also repeals Federal motor vehicle and aviation fuel taxes and modifies qualifying advanced coal project credits. The legislation amends the Clean Air Act to implement a moratorium on EPA's authority to regulate greenhouse gas emissions based on their greenhouse gas effects, for sources subject to the new carbon tax. This moratorium is set to expire in 2039, but can be lifted earlier if specific cumulative emission targets are not met. Exceptions to this moratorium include regulations for new motor vehicles, nonroad engines, and aircraft emissions, as well as certain oil and gas facilities and wastewater treatment plants. Title I also establishes a National Climate Commission , a bipartisan body tasked with setting emissions reduction goals for 2031 and every five years thereafter, based on scientific findings. The Commission will review existing federal policies, assess progress towards these goals, and issue reports with recommendations to the President, Congress, and States. Funding for the Commission's activities is authorized, supplemented by private sector donations, with transparency requirements for all funding and expenditures. To support workers impacted by energy sector transitions, the bill mandates assistance for displaced workers in fossil energy and nuclear power sectors for a period of 10 years. This assistance can include worker retraining, relocation expenses, early retirement benefits, health benefits, block grants for economic redevelopment in affected communities, and transfers to the 1974 United Mine Workers of America Pension Plan. Beyond climate and energy, the bill includes the "KO Cancer Act," which appropriates additional funds to the National Cancer Institute for cancer research and requires a report on cancer drug shortages. It also establishes a Department of Defense Coordinator for engagement with communities affected by PFAS contamination. The "National Bipartisan Fiscal Commission" is created to review and recommend a legislative package for Congress to stabilize long-term deficits and debt, with its recommendations subject to expedited consideration in both the House and Senate. This commission is granted subpoena power and is exempt from the Federal Advisory Committee Act. The "Restriction of Trading and Ownership of Certain Financial Instruments by Members of the House of Representatives" title amends House rules to prohibit Members from owning or trading specific financial instruments, with exceptions for widely held investment funds and government bonds. The "End Banking for Human Traffickers Act" aims to increase the financial industry's role in combating human trafficking by requiring reviews of anti-money laundering procedures and enhancing international standards for eliminating trafficking. The "SAFER Schools Act" directs the Cybersecurity and Infrastructure Security Agency (CISA) to convene a rulemaking advisory committee to develop recommendations for requiring the installation or modification of interior and exterior doors in federally funded schools to enhance security. It authorizes $100 million annually for ten years for grants to implement these security measures. The "Let America Vote Act" requires states to permit unaffiliated voters to participate in primary elections for federal office and incentivizes similar provisions for state and local elections, while also prohibiting non-citizens from voting in any taxpayer-funded election. Finally, the bill mandates a review of intelligence sharing with Ukraine by the Director of National Intelligence to assess its impact on U.S. and allied security. It designates Election Day as a legal public holiday. The "Fairness to Veteran Small Businesses for Infrastructure Investment Act" amends existing law to include veteran-owned small businesses as disadvantaged business enterprises for infrastructure projects. The "Justice for ALS Veterans Act" extends increased dependency and indemnity compensation to surviving spouses of veterans who die from amyotrophic lateral sclerosis (ALS) and requires a report on other medical conditions that should receive similar treatment.
