63  Emissions from carbon stock burnt
Note If a fire occurs, methane and nitrous oxide emissions from the fire are subtracted from the net abatement amount in the reporting period in which the fire occurs. See Equation 32.
 (1) This section applies if the natural disturbance was a fire.
 (2) For each land parcel in a stratum affected by a fire, the amount of carbon stock burnt must be calculated using the following equation:
  Equation 31

  Where:
    aboveground biomass stock, in tonnes C per hectare, in the project scenario assumed to be combusted during a fire event for parcel , in current reporting period .
    the carbon stock of logging slash, in tonnes C per hectare, remaining as debris at the end of the crediting period for all species in land parcel —from Equation 6.
    0.1 being the debris decay factor.
=   the number of years between the harvest in land parcel and the end of the crediting period.
    the annualised growth rate after harvest, in tonnes C per hectare per year, for land parcel —from Equation 18.
 =  years between start of crediting period and start of reporting period  in which natural disturbance in land parcel occurred.

 (3) Emissions of methane from the burnt carbon stock must be calculated using the following equation:
   Equation 32

  Where:
   emissions from methane (CH4), in tonnes CO2-e per hectare, due to fire in land parcel  in reporting period.
   aboveground biomass stock, in tonnes C per hectare,  in the project scenario but absent in the baseline assumed to be combusted during a fire event for land parcel in reporting period —from Equation 31.
   the burning efficiency for wildfires in the National Inventory Report.
   emissions factor for methane, in tonnes of CH4 per tonne of element in fuel burnt, from forest biomass burning in the National Inventory Report.
   elemental to molecular mass conversion factor for methane in the National Inventory Report.
   global warming potential of methane as specified in the NGER Regulations.

 (4) Emissions of nitrous oxide from the burnt carbon stock must be calculated using the following equation:
    Equation 33

  Where:
    emissions from nitrous oxide (N2O), in tonnes CO2-e per hectare, due to fire in land parcel  in reporting period.
    aboveground biomass stock, in tonnes C per hectare, in the project scenario but absent in the baseline assumed to be combusted during a fire event for land parcel , in current reporting period —from Equation 31.
    the burning efficiency for wildfires in the National Inventory Report.
    emission factor for nitrous oxide, in tonnes of N2O per tonne of element in fuel burnt, from forest biomass burning in the National Inventory Report.
    elemental to molecular mass conversion factor for nitrous oxide in the National Inventory
