Carbon Dioxide Emissions Associated with Bioenergy and Other Biogenic Sources

Carbon dioxide (CO2) emissions from bioenergy and other biogenic sources are generated during the combustion or decomposition of biologically-based material. Examples of biogenic CO2 emissions include, but are not limited to:

  • CO2 generated from the biological decomposition of waste in landfills, wastewater treatment or manure management processes
  • CO2 from the combustion of biogas collected from biological decomposition of waste in landfills, wastewater treatment, or manure management processes
  • CO2 from fermentation during ethanol production
  • CO2 from combustion of the biological fraction of municipal solid waste or biosolids
  • CO2 from combustion of the biological fraction of tire-derived fuel
  • CO2 derived from combustion of biological material, including all types of wood and wood waste, forest residue, and agricultural material

EPA has taken a number of actions related to biogenic CO2 emissions from stationary sources including:
