|Table A.3. Carbon Dioxide Uncontrolled Emission Factors|
|Fuel||EIA Fuel Code||
Factor (Kilograms of CO2 Per Million Btu)**
|Distillate Fuel Oil||DFO||73.16|
|Municipal Solid Waste||MSW||41.69|
|Refined Coal||RC||93.3||Assumed to have emissions similar to Bituminous Coal.|
|Residual Fuel Oil||RFO||78.79|
|Synthesis Gas Derived from Coal||SGC||*||Factor is based on the fuel source used to produce the synthesis gas|
|Synthesis Gas Derived from Petroleum Coke||SGP||*||Factor is based on the fuel source used to produce the synthesis gas|
|Waste Coal||WC||93.3||Assumed to have emissions similar to Bituminous Coal.|
* Factors for synthesis gas derived from coal and synthesis gas derived from petroleum coke are based on the fuel source used to produce the synthesis gas.
** CO2 factors do not vary by combustion system type or boiler firing configuration.
