I came across these answers to frequently asked questions from the U.S. Energy Information Administration.  There’s some good information on emissions and conversion factors:

 

  • How much carbon dioxide (CO2) is produced when different fuels are burned?
  • How much CO2 does the United States emit? Is it more than other countries?
  • What are the largest sources of total greenhouse gas emissions by sector for the United States?
  • Where can I find emission factors for greenhouse gases and air pollutants?
  • How much of U.S. greenhouse gas emissions are associated with electricity generation?
  • What are the largest sources of energy-related carbon dioxide emissions by fuel?
  • What are greenhouse gases and how do they affect the climate?
  • Why do carbon dioxide emissions weigh more than the original fuel?
  • Does EIA report water vapor emissions data?
  • How does the hole in the ozone layer affect global warming?
  •  How do I convert between short tons and metric tons?
