The Greenhouse Gases (GHG) Program Area includes the latest guidance and information resources to aid Federal facilities in managing greenhouse gas emissions. This encompasses current guidance, policies, and trends related to climate change/global warming, calculation of carbon footprints, and the application of offsets to reduce carbon footprints.

The primary 6 GHGs of concern are: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. The main sources of these gases due to human activity are as follows:

  • Carbon Dioxide (CO2): burning of fossil fuels and deforestation;
  • Methane (CH4): livestock enteric fermentation (i.e. cows) and manure management, paddy rice farming, land use and wetland changes, pipeline losses, and covered vented landfill emissions;
  • Hydrofluorocarbons (HFCs): these items are of concern from the standpoint of global warming and the Kyoto Protocol;
  • Perfluorocarbons (PFCs): these are being used in refrigerating units as replacements for CFCs;
  • Nitrous Oxide (N2O): this is used for its anesthetic and analgesic effects as well as being used as an oxidizer in rocketry and in motor racing to increase the power output of engines;
  • Sulfur Hexafluoride (SF6): used in the electrical industry as a gaseous dielectric medium for high-voltage (35 kV and above) circuit breakers, switchgear, and other electrical equipment, often referred to as SF6. SF6 is also employed as a contrast agent for ultrasound imaging. See the DOE Safety Bulletin for more information on SF6.

Executive Order 14057: Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability was signed by President Biden on 8 December 2021.

In relation to energy and environmental performance, EO 14057 states that it is the policy of the United States that the Federal Government leads by example to achieve a carbon pollution-free electricity sector by 2035 and net-zero emissions economy-wide by no later than 2050. Through a whole-of-government approach, the United States will demonstrate how innovation and environmental stewardship can protect our planet, safeguard Federal investments against the effects of climate change, respond to the needs of all of America's communities, and expand American technologies, industries, and jobs.

EO 14057 directs federal facilities to transition Federal procurement and operations towards a focus on clean zero-emission technologies, this includes:

  • Reducing Agency Greenhouse Gas Emissions. Each agency shall reduce its scope 1, 2, and 3 greenhouse gas emissions, as defined by the Federal Greenhouse Gas Accounting and Reporting Guidance, by setting and meeting targets for fiscal year 2030 measured from a fiscal year 2008 baseline.
  • Transitioning to 100 Percent Carbon Pollution-Free Electricity. Each agency shall increase its percentage use of carbon pollution-free electricity, so that it constitutes 100 percent of facility electrical energy use on an annual basis and seek to match use on an hourly basis to achieve 50 percent 24/7 carbon pollution-free electricity, by fiscal year 2030.
  • Transitioning to a Zero-Emission Fleet. Each agency's light-duty vehicle acquisitions shall be zero-emission vehicles by the end of fiscal year 2027. Each agency with a fleet comprising at least 20 vehicles shall develop and annually update a zero-emission fleet strategy that shall include optimizing fleet size and composition; deploying zero-emission vehicle refueling infrastructure; and maximizing acquisition and deployment of zero emission light-, medium-, and heavy-duty vehicles where the General Services Administration (GSA) offers one or more zero-emission vehicle options for that vehicle class.
  • Achieving Net-Zero Emissions Buildings, Campuses, and Installations. Each agency shall achieve net-zero emissions across its portfolio of buildings, campuses, and installations by 2045 and reduce greenhouse gas emissions by 50 percent from buildings, campuses, and installations by 2032 from 2008 levels, prioritizing improvement of energy efficiency and the elimination of onsite fossil fuel use.
  • Sustainable Acquisition and Procurement. CEQ shall consider establishing Federal food procurement policies to reduce associated greenhouse gas emissions and drive sustainability in the Federal food supply chain.
  • Adapting the Federal Government to the Impacts of Climate Change. Consistent with its mission, each agency shall: develop or revise polices and processes to promote climate resilient investment that advances adaptation to climate change and protects public health and the environment; conduct climate adaptation analysis and planning for climate-informed financial and management decisions and program implementation; reform agency policies and funding programs that are maladaptive to climate change and increase the vulnerability of communities, natural or built systems, economic sectors, and natural resources to climate impacts, or related risks; and develop and enhance tools that assess climate change impacts and support climate adaptation planning and implementation.

The Implementing Instructions for EO 14057 issued August 2022 provides instructions to Federal agencies regarding the implementation of EO 14057 including agency planning, reporting requirements, and accountability.

E.O. 14057 establishes a policy that the Federal Government will lead by example to help transition the Nation to a net-zero emissions economy by 2050 by setting governmentwide goals for a 65 percent reduction in scope 1 and 2 GHG emissions by 2030 from 2008 levels and achieving net-zero emissions procurement. To achieve these government-wide goals, the E.O. requires agencies to set individual scope 1 and scope 2 reduction targets, as well as scope 3 reduction targets, and meet building, fleet, and operational goals aimed at reducing these emissions.

GHG emissions are categorized as (Scope 1, 2, or 3 and defined as follows:

  • Scope 1 emissions: GHG emissions from sources that are owned or controlled by a Federal Agency (e.g. vehicles and equipment, stationary sources, on-site landfills and wastewater treatment, fugitive emissions).
  • Scope 2 emissions: GHG emissions resulting from the generation of electricity, heat, or steam purchased by a Federal agency (e.g. purchased electricity, purchased heating/cooling, purchased steam).
  • Scope 3 emissions: GHG emissions from sources not owned or directly controlled by a Federal agency but related to agency activities (e.g. transmission and distribution losses from purchased electricity, business travel, employee commuting, contracted waste disposal).
Targets: Agencies will set individual 2030 GHG reduction targets for scope 1, scope 2, and scope 3 emissions.

For Scope 1 and 2 Emissions: Agencies must report scope 1 and 2 emissions as part of the Annual Energy Management Data Report, due annually on 31 January to DOE-FEMP.

Consistent with sections 102 and 202 of E.O. 14057 and the approach taken under previous Executive Orders, agencies must measure scope 1 and 2 reductions from a FY 2008 baseline. Consistent with section 509(c) of the E.O. and section IV.A.3 of M-22-06, DOE-FEMP must develop and provide agencies with agency scope 1 and scope 2 GHG target setting tools and instructions. The tools should take into account projected GHG reductions resulting from each agencies achievement of their CFE, ZEV, and building--related GHG goals.

For Scope 3 Emissions: Consistent with section 302 of E.O. 14057, GSA, in coordination with CEQ and OMB, must assess systems and methodologies to track and report government-wide and agency-specific scope 3 emissions. When directed, each agency must develop and submit a FY 2030 target, along with annual progress targets, based on CEQ guidance.

Metrics: Percentage reduction of emissions measured in metric tons of carbon dioxide equivalent (MTCO2e) from the baseline year as established by the E.O.

Progress Milestones: Agencies will set net annual progress targets based on CEQ guidance.

Consistent with section 503 of E.O. 14057 and section IV.A of M-22-06, agencies must track progress and provide reporting on GHG. Agency progress and performance data for GHG will be collected through established Federal reports and systems including:

  • Annual Energy Management Data Report (Annual Energy Report): Agencies submit this annual report to DOE-FEMP. It includes reporting of annual energy, and water use, CFE, investments in facility efficiency, new building design compliance, metering, and GHG emissions data.
  • Federal Automotive Statistical Tool (FAST): DOE's Idaho National Laboratory, in coordination with GSA, maintains this system for data on vehicle inventories, acquisitions, electric vehicle supply equipment (EVSE) installations, fuel use, and mileage.

In this fact sheet the Administration is announcing new actions across agencies to support American leadership on clean manufacturing. The industrial sector is also central to tackling the climate crisis, as it is currently responsible for nearly a third of domestic greenhouse gas emissions. By helping manufacturers use clean energy, efficiency upgrades, and other innovative technologies to reduce emissions, the Administration is supporting cleaner industry that can produce the next generation of products and materials for a net-zero economy. These same manufacturing improvements will also protect public health, by reducing releases of air and water pollutants and toxic materials that disproportionately harm low-income households and communities of color.
This fact sheet lays out the Biden-Harris Administration's agenda to make equitable and efficient electric options available for everyone. The Administration goals are to reduce America's greenhouse gas (GHG) emissions by 50-52% by 2030, to achieve a carbon pollution-free electricity grid by 2035, and to reach net-zero GHG emissions by no later than 2050.
This fact sheet provides information on the proposed Federal Supplier Climate Risks and Resilience Rule. This rule is part of the President's leadership to implement the first comprehensive, government-wide strategy to measure, disclose, manage, and mitigate the systemic risks that climate change poses to American families, businesses, and the economy. In addition to protecting federal supply chains, agencies are taking new actions to protect pensions and retirement plans, insurance availability, household savings and credit, state and local government programs, our financial system, and the federal budget from the financial risks of climate change.
This fact sheet outlines new steps that will catalyze action across the federal government to account for climate change impacts in budgeting, procurement, and other agency decisions, and save hardworking families money. Specifically, the President is directing agencies to: 1) consider the Social Cost of Greenhouse Gases (SC-GHG) in the development and implementation of their budgets, 2) consider the SC-GHG in federal procurement processes, and 3) consider the SC-GHG in environmental reviews conducted pursuant to the National Environmental Policy Act (NEPA) as appropriate.
Federal agencies were required to develop an adaptation and resilience plan to address their most significant climate risks and vulnerabilities. As outlined in EO 14057 and accompanying Federal Sustainability Plan, agencies will implement the actions identified in their Climate Adaptation and Resilience Plans and will provide annual updates on progress made.

The instructors will provide brief case studies highlighting how their respective organizations adapted process elements to meet their business objectives. Key questions that will be addressed include determining objectives, establishing a baseline, establishing a business as usual forecast, setting GHG reduction targets, selling to senior management, and how to devise a viable implementation plan. The instructors will also provide direction on applicable tools and references, and they will lead discussion on how to overcome some of the most challenging obstacles.
On 2 December 2023, EPA issued a final rule that will sharply reduce emissions of methane and other harmful air pollution from oil and natural gas operations -- including, for the first time, from existing sources nationwide. The final action includes New Source Performance Standards to reduce methane and smog-forming volatile organic compounds from new, modified, and reconstructed sources. It also includes Emissions Guidelines, which set procedures for states to follow as they develop plans to limit methane from existing sources. Oil and natural gas operations are the largest industrial source of methane pollution in the U.S.
This course will train experts in GHG accounting for energy efficiency projects.
The objective of the course is to provide an understanding of the current status of accounting approaches for forest and other land use projects and to go through a process of how GHG accounting for forest and other land use projects is done.
This course provides comprehensive and detailed guidance on developing forest GHG inventories.
This course will train experts in preparing inventories and emission reduction projects for landfill gas methane sites.
This course provides training to individuals who wish to be involved in the implementation of clean development mechanism (CDM) projects in the technical area TA1.2: Energy generation from renewable energy sources. The course focuses on hydropower and wind energy projects.
This course includes: an overview of existing GHG verification approaches; a step by step process for planning, executing, and completing a GHG verification; and reference case studies.

At the 2018 Winter Olympic Games, the US brought home its first-ever gold medal in cross country skiing. A huge milestone in the sport, and now with a new inspired generation of cross country skiers, how can we get them and keep them on the snow? How do we create equity in opportunity for those with barriers to access winter trails? Non-motorized winter trail networks exist throughout the US, and we will take the opportunity to gather the tribe of winter trail specialists for this particular webinar, feature a few expert panelists from different parts of the US, and invite a robust discussion. The content will touch on the universal issues of adapting to climate change and building resiliency in operations, but also consider specific geographic factors such as snow type and regional winter recreation culture. Underlying all of the tactical discussion, we will frame the discussion in the bigger picture of land conservation and stewardship. This webinar is designed for the entire tribe of winter trails professionals, stewards, and program providers of all levels of expertise from novice to expert. The discussion will be centered around groomed winter trails for XC skiers, but will also address the importance of providing opportunities for snowshoeing, fatbiking, winter hiking, and winter trail running.
Recordings of the lower carbon construction materials webinars are now available on the EPA website. The webinars covered topics related to new programs made possible by a $350 million investment from the Inflation Reduction Act such as a new carbon labelling program for construction materials and products, how to improve data on embodied greenhouse gas emissions and new programs to help businesses calculate and report these emissions.

A series of webinars for federal contractors on managing greenhouse gas (GHG) emissions is now available on YouTube. The webinars were developed by EPA and the General Services Administration (GSA) to help federal contractors aid the federal government in meeting its goal of net-zero emissions from procurement by measuring and publicly disclosing their GHGs, setting science-based targets and identifying opportunities to reduce climate impacts. Read more about the Biden-Harris administration's goals for sustainable procurement in Executive Order 14057 and the accompanying Federal Sustainability Plan.
