Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2003

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: 1990-2003 is available for public review. Annual U.S. emissions for the period of time from 1990-2003 are summarized and presented by source category and sector. The inventory contains estimates of carbon dioxide (CO

2

), methane (CH

4

), nitrous oxide (N

2

O), Hydrofluorocarbons (HFC), perflourocarbons (PFC), and sulfur hexaflouride (SF

6

) emissions. The inventory also includes estimates of carbon sequestration in U.S. forests. 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 United Nations Framework Convention on Climate Change (UNFCCC) reporting guidelines. The Inventory of U.S. Greenhouse Gas Emissions and Sinks is the latest in a series of annual U.S. submissions to the Secretariat of the UNFCCC.
