47  Calculating net carbon stock in a CEA at the end of reporting period
Carbon stock in ith CEA at end of reporting period—new plantation CEA
 (1) If the ith CEA is a new plantation CEA, its carbon dioxide equivalent carbon stock at the end of the reporting period (CP,i) (in tonnes CO2‑e) is calculated using the following equation:
  Equation 14

  where:
 is the C mass in forest debris (in tonnes C per hectare) for the ith CEA in the last month of the reporting period—from the project scenario simulation.
 is the C mass of trees (in tonnes C per hectare) for the ith CEA in the last month of the reporting period—from the project scenario simulation.
 is the area (in hectares) of the ith CEA.
Carbon stock in ith CEA at end of reporting period—conversion CEA, permanent planting (environmental) CEA or continuing plantation CEA
 (2) If the ith CEA is a conversion CEA, continuing plantation CEA or a permanent planting (environmental) CEA, its carbon dioxide equivalent carbon stock at the end of the reporting period (CP,i) (in tonnes CO2‑e) is calculated using the following equation:
  Equation 15

  where:
 is:
 (a) if the ith CEA is a conversion CEA or a continuing plantation CEA—the net baseline carbon stock for the ith CEA—from equation 3; and
 (b) if the ith CEA is a permanent planting (environmental) CEA—the net baseline carbon stock for the ith CEA—from equation 6.
n is:
 (a) if fewer than 180 months have been completed since the ith CEA was defined—the number of months completed; and
 (b) otherwise—180.
 is:
 (a) if the ith CEA is a conversion CEA or a continuing plantation CEA—the predicted long-term average project carbon stock for the modelling period for the ith CEA—from equation 8; and
 (b) if the ith CEA is a permanent planting (environmental) CEA—the predicted long-term project scenario carbon stock for the modelling period for the ith CEA—from equation 9.
Note: Essentially, the effect of this equation is to credit the proponent with 1/15 of the expected increase in the quantity of sequestered carbon in the CEA in each of the first 15 years of the project. This increase is averaged for conversion and continuing plantation CEAs, and based on carbon stocks at the end of the reporting period for ex-plantation CEAs. In practice, the amounts credited are likely to vary slightly from one reporting period to the next because  and  are re-calculated for each reporting period, and the scenarios used in the calculations are modified to reflect events that occurred during the reporting period. This recalculation may continue to produce adjustments after the initial period of 15 years. The calculation is done monthly to facilitate reporting more frequently than yearly.
