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

* 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.
