a Sinks are only included in net emissions total.
b Emissions from International Bunker Fuels and Wood Biomass and Ethanol Consumption 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.
1990-2005 Trends
Total GHG emissions rose 16 percent since 1990 (increasing
1.6 percent since 2000)
Dominant gas emitted was C02, mostly from fossil fuel combustion
Methane emissions decreased by 11 percent
Nitrous oxide emissions decreased by 3 percent
HFC, RFC, and SF6 emissions have grown by 83 percent

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.
