This is a bug fix release. No data sources have been changed.

Corn ethanol may have been having too-high fuel production numbers in cases where the fuel year and model year were both later than 2010. The coproduct emissions and energy were not being calculated correctly for bone meal. This change will only effect tallow based biodiesel when it was using energy based allocation. While these may produce different results, neither change the default results.


  • Fixed an issue where the bone meal coproduct for biodiesel was using the wrong energy value.
  • Fixed an issue where sugar beat and sorghum based ethanols were using the wrong sequestration fraction.
  • Fixed an issue where corn, wheat, barley, pea, and sugarcane based ethanol would sometimes incorrectly increase the natural gas input.
  • Fixed some labelling.
