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 (EO) 13834, Efficient Federal Operations, was signed by President Trump on 17 May 2018. Section 8 of this EO revokes EO 13693.

In relation to energy and environmental performance, EO 13834 states that it is the policy of the United States that agencies shall meet such statutory requirements in a manner that increases efficiency, optimizes performance, eliminates unnecessary use of resources, and protects the environment.

Section 2, paragraph (h) of EO 13834 directs federal facilities to continue tracking and reporting on energy greenhouse gas emissions.

Efficient Federal Operations
17 May 2018
It is the policy of the United States that agencies shall meet such statutory requirements in a manner that increases efficiency, optimizes performance, eliminates unnecessary use of resources, and protects the environment. In implementing this policy, each agency shall prioritize actions that reduce waste, cut costs, enhance the resilience of Federal infrastructure and operations, and enable more effective accomplishment of its mission. This EO rescinds EO 13693.
This CEQ website links to relevant U.S. codes, public laws, guidance, and resources to assist agencies in implementing E.O. 13834.
This CEQ guidance, dated 17 January 2016, provides direction for calculating and reporting GHG emissions in accordance with E.O. 13693 directives. Agencies shall follow this Guidance to ensure consistent and transparent reporting of Federal GHG emissions. This Guidance is accompanied by appendices that provide more detailed information on inventory reporting, calculation methodologies, and emission factors. This Guidance is not designed for quantifying the reductions from individual GHG mitigation projects, nor does it include strategies for reducing GHG emissions. If an agency identifies a GHG emissions reduction activity or practice that is not covered in this guidance document, and wishes to receive GHG emissions reduction credit for such an activity or practice, the agency should consult with CEQ and the Office of Management and Budget (OMB) to receive documented approval of the proposed activity or practice and the accounting methodology beforehand.

Lessons Learned
 
Case Studies
This report, dated March 2011, presents a series of case studies describing the approaches currently being taken by four water utilities in the United States to assess their vulnerability to climate change. The case studies illustrate different approaches that reflect specific local needs and conditions, existing vulnerabilities, local partnerships, and available information about climate change. Information from these case studies will be useful to water utilities and other members of the water resources community to inform the development of strategies for understanding and responding to climate change. This report was prepared by the National Center for Environmental Assessment's Global Climate Research Staff in the Office of Research and Development.
Published by the U.S. Global Change Research Program in 2009, the report summarizes the science and the impacts of climate change on the United States, now and in the future.
