Totals may not sum perfectly due to the rounding of source data.

“Other” includes greenhouse gas emissions from pipelines and lubricants.

Road data is a combination of data for passenger cars, light-duty trucks, other trucks, buses and motorcycles (2005-2009). Motorcycles are included in the “Other” CO2 emissions for all years prior to 2005.

“Other” CO2 for 1996 is listed as unavailable due to a change in methodology which renders that datum incompatible with previous years.

There is no “Other” category for methane and nitrogen oxide.

International bunker fuels are not included.

The Environmental Protection Agency (EPA) modifies its methodology on an annual basis.

Emissions of greenhouse gases from various source and sink categories have been estimated by EPA using methodologies that are consistent with Intergovernmental Panel on Climate Change Guidelines for National Greenhouse Gas Inventories. For additional methodological information, see: http://epa.gov/climatechange/emissions/usinventoryreport.html.

Totals may not match totals from source data due to rounding by the source.
