Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2012

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of document availability and request for comments.

-----------------------------------------------------------------------

SUMMARY: The Draft Inventory of U.S. Greenhouse Gas Emissions and 
Sinks: 1990-2012 is available for public review. Annual U.S. emissions 
for the period of time from 1990 through 2012 are summarized and 
presented by source category and sector. The inventory contains 
estimates of carbon dioxide (CO2), methane (CH4), 
nitrous oxide (N2O), hydrofluorocarbons (HFC), 
perfluorocarbons (PFC), and sulfur hexafluoride (SF6) 
emissions. The inventory also includes estimates of carbon fluxes in 
U.S. agricultural and forest lands. The technical approach used in this 
report to estimate emissions and sinks for greenhouse gases is 
consistent with the methodologies recommended by the Intergovernmental 
Panel on Climate Change (IPCC), and reported in a format consistent 
with the

[[Page 10144]]

United Nations Framework Convention on Climate Change (UNFCCC) 
reporting guidelines. The Inventory of U.S. Greenhouse Gas Emissions 
and Sinks: 1990-2012 is the latest in a series of annual U.S. 
submissions to the Secretariat of the UNFCCC. EPA requests 
recommendations for improving the overall quality of the inventory 
report to be finalized in April 2014, as well as subsequent inventory 
reports.
