" Sinks are only included in net emissions total.
b Emissions from International Bunker Fuels and Biomass Combustion are not included in totals.
Note: Totals may not sum due to independent rounding. Emissions weighted using GWP values from IPCC Second Assessment Report
(1996) in keeping with UNFCCC reporting guidelines.
1990-2004 Trends
• Total GHG emissions rose 16 percent since 1990 (increasing
1.3 percent since 2000)
• Dominant gas emitted was C02, mostly from fossil fuel combustion
• Methane emissions decreased by 10 percent
• Nitrous oxide emissions decreased by 2 percent
• HFC, RFC, and SF6 emissions have grown by 58 percent

b IPCC Third Assessment Report (2001)
* The methane GWP includes the direct effects
and those indirect effects due to the production of
tropospheric ozone and stratospheric water vapor.
The indirect effect due to the production of C02 is
not included.
Note: GWP values from the IPCC Second Assessment
Report are used in accordance with UNFCCC
guidelines.
Global Warming Potential (GWP) is defined as
the cumulative radiative forcing effects of a gas
over a specified time horizon resulting from the
emission of a unit mass of gas relative to a
reference gas. The GWP-weighted emissions of
direct greenhouse gases in the U.S. Inventory
are presented in terms of equivalent emissions
of carbon dioxide (C02), using units of teragrams
of carbon dioxide equivalents (Tg C02 Eq.).
Conversion:
Tg = 109kg = 106 metric tons
= 1 million metric tons
The molecular weight of carbon is 12,
and the molecular weight of oxygen is 16;
therefore, the molecular weight of C02 is
44 (i.e., 12 + [16x2]), as compared to 12
for carbon alone. Thus, carbon comprises
12/44ths of carbon dioxide by weight.
Conversion from gigagrams of gas to teragrams
of carbon dioxide equivalents:

Energy Conversions
The common energy unit used in
international reports of greenhouse
gas emissions is the joule. A joule
is the energy required to move an
object one meter with the force of
one Newton. A terajoule (TJ) is one
trillion (1012) joules. A British thermal
unit (Btu, the customary U.S. energy
unit) is the quantity of heat required
to raise the temperature of one pound
of water one degree Fahrenheit at or
near 39.2 Fahrenheit.

May include adjustments for carbon stored in fossil fuel-based products,
emissions from international bunker fuels, or emissions from territories.
Carbon Intensity of Different Fuel Types
The amount of carbon in fossil fuels per unit of energy content varies significantly by fuel type.
For example, coal contains the highest amount of carbon per unit of energy, while petroleum
has about 25 percent less carbon than coal, and natural gas about 45 percent less.
Converting Various Physical Units to Energy Units
The values in the following table provide conversion factors from physical units to energy
equivalent units and from energy units to carbon contents. These factors can be used as
default factors, if local data are not available.
