A bill to reduce greenhouse gas emissions and protect the climate. (Congressional Record 18 November 2025 [House] Pages H4768-H4770)

In this action, the U.S. Environmental Protection Agency (EPA) is proposing to repeal all greenhouse gas (GHG) emissions standards for fossil fuel-fired power plants. The EPA is proposing that the Clean Air Act (CAA) requires it to make a finding that GHG emissions from fossil fuel-fired power plants contribute significantly to dangerous air pollution, as a predicate to regulating GHG emissions from those plants. The EPA is further proposing to make a finding that GHG emissions from fossil fuel-fired power plants do not contribute significantly to dangerous air pollution. The EPA is also proposing, as an alternative, to repeal a narrower set of requirements that includes the emission guidelines for existing fossil fuel-fired steam generating units, the carbon capture and sequestration/storage (CCS)-based standards for coal-fired steam generating units undertaking a large modification, and the CCS-based standards for new base load stationary combustion turbines.

DoD, GSA, and NASA are withdrawing the proposed rule to amend the Federal Acquisition Regulation (FAR) titled: Disclosure of Greenhouse Gas Emissions and Climate-Related Financial Risk. Executive Order 14030, directed the Federal Acquisition Regulatory Council to consider amending the Federal Acquisition Regulation (FAR) require major Federal suppliers to publicly disclose greenhouse gas emissions and climate-related financial risk and to set science-based reduction targets. A proposed rule was published on 14 November 2022. The agencies lack sufficient time during the Biden-Harris Administration to finalize the proposal. In addition, the agencies' analysis of public comments indicates an evolving practices and standards in industry, and an evolving domestic and international regulatory landscape. Accordingly, this proposed rule is withdrawn, and the FAR case is closed. The proposed rule published on 14 November 2022, at 87 FR 68312 is withdrawn as of 13 January 2025. POC is Ms. Jennifer Hawes, Procurement Analyst, at 202-255-9194 or by email at jennifer.hawes@gsa.gov.

The USGS recently released a new report analyzing greenhouse gas emissions  including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)  associated with U.S. federal lands. Published as a follow-up to an earlier USGS 2018 report, it incorporates the latest data and methodologies, expanding the timeframe of analysis from 2005 to 2022 while providing updated estimates of ecosystem carbon emissions and sequestration. Given that U.S. federal lands are approximately 28% of the land in the United States, understanding both greenhouse gas emissions and sequestration on these lands is essential to informing land management practices that can mitigate greenhouse gas emissions.

EPA released its 50th annual Automotive Trends Report, demonstrating that model year 2023 vehicle fuel economy reached a record high while greenhouse gas emissions dropped to record low levels. The report also shows that all 14 large automotive manufacturers are in compliance with EPA's light-duty GHG program requirements through the MY 2023 reporting period. The new MY 2023 electric vehicles and plug-in hybrid electric vehicles on the road have led to 11% lower CO2 emissions. Despite these significant improvements in local air pollution that have benefited Americans, passenger cars and light trucks still accounted for nearly 17% of total U.S. GHG emissions in 2022, indicating the importance of further reductions in GHG emissions and improvements in fuel economy. This annual report reflects EPA's commitment to provide the public with information about new light-duty vehicle greenhouse gas emissions, fuel economy, technology data, and auto manufacturers' performance in meeting the nation's emissions standards. EPA's annual Automotive Trends Report is separate from the agency's regulatory process.

The Environmental Protection Agency (EPA) is promulgating a regulation to facilitate compliance with the requirements of the Waste Emissions Charge in the Clean Air Act's (CAA) Methane Emissions Reduction Program (MERP). Enacted as part of the Inflation Reduction Act (IRA), this program requires the EPA to impose and collect an annual charge on methane emissions that exceed waste emissions thresholds specified by Congress. This final rule is effective 17 January 2025.

EPA released 2023 greenhouse gas data collected under the EPA's Greenhouse Gas Reporting Program. In 2023, reported direct emissions of greenhouse gases from large stationary sources, representing approximately 50% of total U.S. emissions, were down by approximately 4% from 2022. From 2011 to 2023, total reported GHG emissions from large facilities decreased by approximately 22%, driven by a decrease in power plant emissions. This is the fourteenth year of data collection for most sectors under the GHGRP. As directed by Congress, EPA collects annual, facility-level emissions data from major industrial sources, including power plants, oil and gas production, iron and steel mills, and landfills. More than 8,100 direct emitters and suppliers report GHG data to GHGRP.

The DOE announced that it has delivered on Congress's mandate to cut emissions from new or newly renovated federal buildings through the Clean Energy for New Federal Buildings and Major Renovations of Federal Buildings Rule. By meeting the requirements of the Rule, federal buildings will reduce pollution, improve air quality, create good-paying jobs, and take advantage of cost savings from using more energy-efficient equipment. These measures will help advance the adoption of cleaner, more efficient technologies for buildings that will lead the way to achieving President Biden's Federal Sustainability Plan goal of net-zero emissions from all federal buildings by 2045. This Rule, which implements the Energy Independence and Security Act (EISA) of 2007, requires federal agencies to phase out fossil fuel usage in new federal building construction or major renovation by achieving a 90% reduction in fossil fuel use for new projects started between fiscal years 2025 and 2029 and completely eliminating on-site fossil fuel usage in new projects beginning in 2030.

The White House has just announced the first Climate Resilience Game Changers Assessment , identifying 28 critical technologies, management practices, and institutional and financial tools that can drive transformative positive impacts on our nation's climate resilience.

This package of materials is intended to be used by building owners and operators to develop a scope of work for a building-level Greenhouse Gas (GHG) Emissions Reduction Audit for operational Scope 1 and 2 GHG emissions. The aim of the scope of work template is to achieve building-level solutions that will reduce operational emissions.

EPA released its 2024-2027 Climate Adaptation Plan, which describes agency actions to address the impacts of climate change and help build a more climate-resilient nation. The plan expands the agency's efforts to ensure its programs, facilities, workforce and operations are increasingly resilient to climate change impacts. EPA plays a central role in the Administration's efforts to tackle the climate crisis and build a climate-resilient nation. The plan builds on work initiated in the 2014 and 2021 EPA Climate Adaptation Plans to incorporate climate adaptation into the agency's programs, policies, rules, enforcement activities and operations. EPA has already made significant strides partnering with other federal agencies, states, Tribes, territories and local governments to promote climate resilience across the nation, placing a particular focus on advancing environmental justice. Nevertheless, more needs to be done given the magnitude of this global challenge.

DOE announced a National Definition of a Zero Emissions Building to advance public and private sector efforts to decarbonize the buildings sector, which is responsible for more than one-third of total U.S. greenhouse gas emissions. The definition is intended to provide industry guidance to support new and existing commercial and residential buildings to move towards zero emissions across the entire sector and help the nation achieve President's ambitious climate goals, while cutting home and business energy costs. A standardized definition for zero emissions buildings will help advance next-generation clean energy solutions, drive innovation, and tackle the climate crisis, while supporting workforce development.

EPA is amending requirements that apply to the petroleum and natural gas systems source category of the Greenhouse Gas Reporting Rule to ensure that reporting is based on empirical data, accurately reflects total methane emissions and waste emissions from applicable facilities, and allows owners and operators of applicable facilities to submit empirical emissions data that appropriately demonstrate the extent to which a charge is owed under the Waste Emissions Charge. The EPA is also amending certain requirements that apply to the general provisions, general stationary fuel combustion, and petroleum and natural gas systems source categories of the Greenhouse Gas Reporting Rule to improve calculation, monitoring, and reporting of greenhouse gas data for petroleum and natural gas systems facilities. This action also establishes and amends confidentiality determinations for the reporting of certain data elements to be added or substantially revised in these amendments. This rule is effective 1 January 2025.

The Decarbonizing the U.S. Economy by 2050: A National Blueprint for the Buildings Sector, is a comprehensive plan to reduce GHG emissions from buildings by 65% by 2035 and 90% by 2050. DOE led the Blueprint's development in collaboration with the HUD, the EPA, and other federal agencies. The Blueprint is the first sector-wide strategy for building decarbonization developed by the federal government.

EPA announced a final rule, Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles, that sets new, more protective standards to further reduce harmful air pollutant emissions from light-duty and medium-duty vehicles starting with model year 2027. The final rule builds upon EPA's final standards for federal greenhouse gas emissions standards for passenger cars and light trucks for model years 2023 through 2026 and leverages advances in clean car technology to unlock benefits to Americans ranging from improving public health through reducing smog- and soot-forming pollution from vehicles, to reducing climate pollution, to saving drivers money through reduced fuel and maintenance costs. These standards will phase in over model years 2027 through 2032.

The White House Office of Domestic Climate Policy (Climate Policy Office), through the U.S. Department of Energy, seeks to create a standardized, verifiable basis for defining a zero emissions building. A broadly accepted common minimum definition for a zero emissions building, as well as a pathway for verification, is foundational to efforts by public and private entities to transition the building sector to zero emissions. The definition may serve as a framework that users can achieve through multiple pathways to influence the design and operation of buildings to substantially reduce building sector emissions.

This letter summarizes the recommendations of the Green Building Advisory Committee (the Committee), based on the third phase of work of its Federal Building Decarbonization Task Group (FBDTG).

GSA's Green Proving Ground and the Pacific Northwest National Laboratory (PNNL) published LED lighting and controls guidance for Federal buildings. This guidance is in support of the BRIGHT Act.

USGCRP is providing a series of webinars led by the authors of key chapters of this report. These chapter webinars are an opportunity for you to hear about the findings of a particular chapter from the authors themselves. Each virtual one-hour event is expected to include some time for Q&A.

The Fourth National Climate Assessment (NCA4), completed in November 2018, is a comprehensive and authoritative report on climate change and its impacts in the United States.

DOE published the "2023 Better Buildings Initiative Progress Report," which summarizes the achievements of DOE's Better Buildings public and private sector partners since the initiative's inception in 2011. The report shows that partnering entities, including more than 900 businesses, state and local governments, utilities, housing authorities, and other public and private organizations, to date have collectively saved $18.5 billion through efficiency improvements and cut harmful carbon dioxide emissions by nearly 190 million metric tons-- an amount roughly equivalent to combined annual emissions of 24 million homes. This report also includes the results of the Better Climate Challenge, an initiative that challenges major building portfolio owners and industrial partners to cut their greenhouse gas emissions by 50% within 10 years. In year one of the Challenge, partners have reported on nearly 1 billion square feet of buildings and 1,500 industrial plants. Through the Better Buildings Initiative, DOE aims to improve energy efficiency in the commercial, industrial, and residential sectors and accelerate cost-effective decarbonization solutions across the economy--supporting the Administration's efforts to lower energy costs for American families and businesses while addressing the climate crisis.

EPA announced the latest actions to phase down climate-damaging hydrofluorocarbons (HFCs) under the bipartisan American Innovation and Manufacturing (AIM) Act, building on the Biden-Harris Administration's progress in accomplishing an initial 10% reduction and helping achieve an 85% reduction by 2036. The first new action is a final rule to accelerate the ongoing transition to more efficient and climate-safe technologies in new refrigeration, heating and cooling systems and other products by restricting the use of HFCs where alternatives are already available. The second action is a proposed rule to better manage and reuse existing HFCs, including by reducing wasteful leaks from equipment and supporting a growing American industry for HFC recycling and reclamation. Under the AIM Act, the Biden-Harris Administration is phasing down HFCs to achieve a 40% reduction of HFCs starting in 2024 and an 85% reduction by 2036. Today's actions will support the national phasedown, including through an additional $4.5 billion in estimated savings for industry and consumers, while supporting good-paying American manufacturing jobs to produce the next generation of equipment and HFC alternatives.

EPA's National Compliance Initiatives (NCIs) advance the Agency Strategic Plan's objectives to improve air quality, provide for clean and safe water, ensure chemical safety, and improve compliance with our nation's environmental laws while enhancing shared accountability between the EPA and states and tribes with authorized environmental programs.

GSA has reported progress toward key sustainability goals in recent years across its buildings portfolio. In this report GSA's aggregated buildings portfolio data show it exceeded prior goals for energy efficiency, water efficiency, emissions reduction, and renewable electricity share in fiscal year 2021, however GSA officials cited lack of access to capital as a challenge it faces in meeting future federal sustainability goals. GSA officials said the scale and scope of the projects needed to achieve net-zero building emissions by 2045 will require resources beyond what has historically been available.

DOE unlocked billions of dollars in private capital to improve the efficiency and sustainability of federal facilities. DOE competitively awarded contracts to 20 energy service companies (ESCOs) to provide Energy Savings Performance Contracts (ESPCs) for federal agencies, marking the fourth generation of such contracts awarded by DOE since 1998. Energy and water infrastructure projects financed through DOE's ESPC indefinite-delivery, indefinite-quantity (IDIQ) contract offer guaranteed cost savings for federal sites. With a ceiling of $5 billion per ESCO contract, they require no upfront government funding and are designed to pay for themselves over time. Federal agencies interested in initiating their next ESPC project are encouraged to contact the Federal Energy Management Program (FEMP) to get started. Stakeholders, including federal agencies, ESCOs, and the public can visit FEMP's ESPC program page to view the awarded contracts and access further information about ESPCs

EPA announced the latest action to phase down the use of climate super-pollutant hydrofluorocarbons (HFCs), issuing a final rule to implement a 40% reduction below historic levels from 2024 through 2028. The rule aligns with the bipartisan American Innovation and Manufacturing (AIM) Act's goals to reduce the production and consumption of these climate-damaging chemicals by 85% by 2036 and help avoid up to 0.5 ?C of global warming by 2100. The final rule builds on the success of the 10% phasedown step implemented for 2022 and 2023, by establishing a similar allowance methodology to provide regulatory certainty to industry and stakeholders, ensuring the most efficient implementation under the ongoing phasedown. The United States began this historic phasedown on January 1, 2022, with a reduction of HFC production and imports to 10% below historic baseline levels. Since then, allowances are needed to import and produce HFCs. Starting in 2024 the phasedown will be 40% below historic levels, a significant decrease in the number of available production and consumption allowances compared to previous years. HFC allowances for calendar year 2024 will be allocated by September 29, 2023. The phasedown schedule under this program is consistent with the schedule laid out in the Kigali Amendment to the Montreal Protocol, which the United States ratified in October 2022.

Health Care Emissions Impact Calculator is an accounting tool specifically designed to help health care organizations measure their greenhouse gas (GHG) emissions. It was developed following the GHG Protocol and can be used to develop a GHG inventory for all scopes 1, 2, and 3 emissions at the facility and/or system level. Note to access the calculator you need to provide contact information.

The Global Electronics Council recently announced Climate Criteria for its EPEAT ecolabel. Starting in late 2023, products that have been verified to meet these criteria will be listed as Early Adopters on the EPEAT Registry. All products will have to meet the Climate Criteria by December 31, 2025. EPA coordinated comments from federal agencies for the new criteria which includes requirements for public disclosure of climate pollutants, use of renewable energy and energy reduction within the supply chain and during a product's use. The EPEAT label was developed with support from an EPA grant and federal purchasers are required to procure EPEAT registered electronics.

The NAM Climate Collaborative Health Care Delivery Working Group developed a shortlist of key actions for hospitals and health systems to reduce their greenhouse gas emissions. The NAM identified nine actions that can be used by any hospitals or health systems to start their journey to reach decarbonization goals.

EPA proposed new carbon pollution standards for coal and natural gas-fired power plants that will protect public health, reduce harmful pollutants and deliver up to $85 billion in climate and public health benefits over the next two decades. The proposal for coal and new natural gas power plants would avoid up to 617 million metric tons of total carbon dioxide (CO2) through 2042, which is equivalent to reducing the annual emissions of 137 million passenger vehicles, roughly half the cars in the United States. Through 2042, EPA estimates the net climate and health benefits of the standards on new gas and existing coal-fired power plants are up to $85 billion. The proposals would also result in cutting tens of thousands of tons of particulate matter (PM2.5), sulfur dioxide, and nitrogen oxide, harmful air pollutants that are known to endanger people's health, especially in communities that for too long have disproportionally shouldered the burden of high pollution and environmental injustice.

EPA released its 30th annual Inventory of U.S. Greenhouse Gas Emissions and Sinks (GHG Inventory), which presents a national-level overview of annual greenhouse gas emissions from 1990 to 2021. Net U.S. greenhouse gas emissions were 5,586 million metric tons of carbon dioxide equivalent in 2021, a 6% increase in emissions from 2020. The increase is largely due to a rebound in economic activity following the height of the coronavirus (COVID-19) pandemic. However, emissions have declined overall since 2005 (17%), which reflects the combined impacts of several factors, including energy market trends, technological changes including energy efficiency improvements, and the carbon intensity of energy fuel choices. For this latest release, EPA has made several important improvements, including updates to estimates for oil and gas and for flooded lands such as hydroelectric and agricultural reservoirs.

WASHINGTON (Feb. 14, 2023) – Today, the U.S. Environmental Protection Agency (EPA) announced initial guidance on the design of the Greenhouse Gas Reduction Fund (GGRF) program, created by President Biden's Inflation Reduction Act.

The DOE announced a $96 million funding opportunity to support decarbonizing the domestic transportation sector. The funding will focus on expanding electric vehicle (EV) charging accessibility, create cleaner non-road vehicles through electrification and the use of alternative fuels, and develop electric drive components and materials to maximize EV efficiency and affordability. Non-road vehicles, including agricultural and construction equipment, rail, marine and aviation, are a major source of pollution, emitting more carbon pollution than any other sector of the U.S. economy. Lowering vehicle emissions will support President Biden's goal to achieve to net-zero economy by 2050. Further, in accordance with President Biden's Justice40 Initiative, applicants for this funding must show how proposed projects will benefit traditionally disadvantaged communities that lack access to clean energy sources.

This EO directs federal agencies to pursue science-based, sustainable forest and land management; conserve America's mature and old-growth forests on Federal lands; invest in forest health and restoration; support indigenous traditional ecological knowledge and cultural and subsistence practices; honor Tribal treaty rights; and deploy climate-smart forestry practices and other nature-based solutions to improve the resilience of our lands, waters, wildlife, and communities in the face of increasing disturbances and chronic stress arising from climate impacts.

EPA develops an annual report called the Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory), that tracks U.S. greenhouse gas emissions and sinks by source, economic sector, and greenhouse gas going back to 1990. EPA has prepared the Inventory of U.S. Greenhouse Gas Emissions and Sinks since the early 1990s. This annual report, provides a comprehensive accounting of total greenhouse gas emissions for all man-made sources in the United States, including carbon dioxide removal from the atmosphere by "sinks," (e.g., through the uptake of carbon and storage in forests, vegetation, and soils) from management of lands in their current use or as lands are converted to other uses. The gases covered by the Inventory include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride.

The Interagency Task Force on Illegal Hydrofluorocarbon (HFC) Trade announced that over the past ten weeks, it has prevented illegal HFC shipments equivalent to approximately 530,000 metric tons of CO2 emissions, the same amount as the emissions from nearly 100,000 homes' electricity use in one year. As of January 1, 2022, when the EPA's HFC Allowance Allocation and Trading program went into effect, the import of HFCs requires allowances. Shipments coming to U.S. ports without proper allowances have been identified, stopped, and re-exported. In September of 2021, the task force was established when EPA issued a final rule initiating a comprehensive program to cap and phase down the production and consumption of climate-damaging HFCs in the United States, potent greenhouse gases commonly used in refrigeration and air conditioning equipment. A global phasedown of HFCs is expected to avoid up to 0.5 °C of global warming by 2100. The HFC phasedown is projected to avoid approximately 4.6 billion metric tons of CO2 from 2022 – 2050 in the United States, or nearly equal to three years' worth of U.S. power sector emissions at 2019 levels. The task force helps ensure the vast environmental benefits of the rule are realized by detecting, deterring, and disrupting any attempts to illegally import HFCs into the United States.

EPA reinstated California's authority under the Clean Air Act to implement its own greenhouse gas (GHG) emission standards and zero emission vehicle (ZEV) sales mandate. This action concludes the agency's reconsideration of 2019's Safer Affordable Fuel-Efficient Vehicles Rule Part One: One National Program Rule (SAFE-1) by finding that the actions taken under the previous administration as a part of SAFE-1 were decided in error and are now entirely rescinded. With this action, EPA is also withdrawing the SAFE-1 interpretation of the Clean Air Act that would prohibit other states from adopting the California GHG emission standards. As a result, other states may choose to adopt and enforce California's GHG emission standards in lieu of the Federal standards, consistent with section 177 of the Clean Air Act.

Across the United States, many states are developing and publishing state level GHG inventories on a regular basis. This website provides official state ghg inventories where available.

EPA's State Inventory and Projection Tool is an interactive spreadsheet model designed to help states develop greenhouse gas (GHG) emissions inventories and was developed to lessen the time it takes to develop an inventory (collecting data, identifying emission factors, etc.). The tool has two components: the state inventory tool and the projection tool. tool.

This report is a follow-on to the 2019 EPA technical report, Global Non-CO2 Greenhouse Gas (GHG) Emission Projections & Mitigation Potential: 2015-2050. This report provides U.S. domestic technical and economic mitigation estimates of non-CO2 GHGs from anthropogenic sources at the state-level. The analysis provides information that can be used to understand sub-national contributions of GHG emissions and mitigation opportunities. This web-based summary is intended to provide analysis of the abatement potential and costs of implementing specific abatement technologies. The analysis and accompanying dataset provides information that can be used by state and local-policymakers to understand mitigation opportunities in areas that may have not received the same attention as electricity generation and transportation.

The U.S. Department of Energy (DOE) released a study showing that by 2030, nearly half of medium- and heavy-duty trucks will be cheaper to buy, operate, and maintain as zero emissions vehicles than traditional diesel-powered combustion engine vehicles. Published by the DOE's National Renewable Energy Laboratory, the study finds that continued improvements with zero emission vehicle and fuel technologies will enable clean trucks to become cheaper and more readily available over the next decade.

DOD and GSA announced a Request for Information (RFI) to gather market information and capabilities in supplying carbon pollution-free electricity to the federal government. This is an important step forward in transforming how the U.S. government buys and manages electricity, and it puts the nation on a path to achieving a carbon pollution-free electricity sector by 2035. This RFI follows President Biden’s signing of the Executive Order on Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability (EO 14057), which directed the federal government to use 100% carbon pollution-free electricity on a net annual basis by 2030, including 50% on a 24/7 (hourly matching) basis. The objectives of this RFI are to: • Demonstrate the intent to achieve 100 percent carbon pollution-free electricity for federal operations by using a whole-of-government approach; • Understand the ability of industry to supply 24x7 hourly matched carbon pollution-free electricity, and gather pricing information based on scale; and • Gather information from industry on potential approaches to meeting the targets set by the Federal Sustainability Plan. This is a part of the Administration’s larger goal to combat the climate crisis, including working to curb emissions, strengthen resilience, create jobs, protect public health, catalyze private sector investment, spur innovation, expand the economy, and advance equity.

EPA released its 28th annual Inventory of U.S. Greenhouse Gas Emissions and Sinks (GHG Inventory), which presents a national-level overview of annual greenhouse gas emissions from 1990 to 2019. Net U.S. greenhouse gas emissions were 5,769 million metric tons of carbon dioxide equivalent in 2019, a 1.7 percent decrease in emissions between 2018 and 2019. While many long-term and short-term factors influence annual greenhouse gas emissions in recent years, the downward GHG emissions trend can be largely attributed to falling emissions in the electric power sector. The GHG Inventory covers seven key greenhouse gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. In addition to tracking U.S. greenhouse gas emissions, the inventory also calculates carbon dioxide that is removed from the atmosphere through the uptake of carbon in forests and other vegetation. Public review of this year's report occurred from 12 February to 15 March 2021 and comments received are posted to the docket EPAHQ-OAR-2021-0008. Responses to comments will be posted to EPA's website within 2-4 weeks following publication of this report.
