Notes:

1 National totals exclude all GHGs from the Land Use, Land-Use Change and Forestry Sector.

2 Emissions from fuel ethanol are reported within the gasoline transportation subcategories.

3 The category Mineral Product Use includes CO2 emissions from the use of limestone & dolomite, soda ash, and magnesite.

Totals may not add due to rounding.
