62  Carbon dioxide emissions
Note If a natural disturbance occurs, carbon dioxide emissions from the resulting debris pool are subtracted from the net abatement amount in every reporting period for the rest of the crediting period, not only in the reporting period in which the natural disturbance occurs. See Equation 28.
 (1) The annualised carbon dioxide emissions, in tonnes of CO2-e per year, for each land parcel must be calculated using the following formula:
  Equation 27

  Where:
    the annualised carbon dioxide emissions, in tonnes CO2-e per hectare per year, due to natural disturbance in land parcel  in reporting period .
    the carbon stock, in tonnes C per hectare, in the debris pool following a natural disturbance in land parcel —from Equation 26A or 26B.
    0.1 being the debris decay factor.
 =  years between start of reporting period in which natural disturbance occurred 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.

Note The factor   represents the ratio of molecular weights of carbon dioxide to carbon.
 (2) For each reporting period, the annualised carbon dioxide emissions, in tonnes CO2-e per year, from all natural disturbances in the reporting period must be calculated using the following equation:

   Equation 28

  Where:
   the annualised carbon dioxide emissions, in tonnes CO2-e per year, in reporting period .
   the annualised carbon dioxide emissions, in tonnes CO2-e per hectare per year, due to natural disturbance in land parcel p in reporting period r—from Equation 27.
=  the area, in hectares, of land in land parcel affected by natural disturbance  in reporting period —from Equation 25.

 (3) The annualised carbon dioxide emissions from natural disturbances in all reporting periods must be calculated using the following equation:

   Equation 29

  Where:
  the annualised carbon dioxide emissions, in tonnes CO2-e per year, from natural disturbances in all reporting periods.
  the annualised carbon dioxide emissions, in tonnes CO2-e per year, in reporting period r—from Equation 28.

 (4) For each reporting period, the total carbon dioxide emissions from all natural disturbances must be calculated using the following equation:

   Equation 30

  Where:
  the total carbon dioxide emissions, in tonnes CO2-e, from all natural disturbances in reporting period r.
  the annualised carbon dioxide emissions, in tonnes CO2-e per year, for all reporting periods—from Equation 29.
  the number of years in reporting period.
