92  Calculating carbon stock change for a stratum
 (1) Where a stratum is referenced in an offsets report under this determination, the calculation of the carbon stock change for the first and subsequent reporting periods must:
 (a) be carried out in accordance with:
 (i) Equation 3a for the first reporting period; and
 (ii) Equation 3b for subsequent reporting periods; and
 (b) incorporate a standard error calculation in accordance with:
 (i) Equation 3c for the first reporting period; and
 (ii) Equation 3d for subsequent reporting periods.
Calculating carbon stock for the first reporting period for the stratum
 (2) Carbon stock change for a stratum is to be calculated for the first reporting period in which the stratum is referenced using the following formula:
   Equation 3a

  where:
 =  carbon stock change for the th stratum for the reporting period in tonnes of CO2‑e (t CO2‑e).

 =  closing carbon stock for the th stratum for the reporting period in tonnes of CO2‑e (t CO2‑e):
       (a)  calculated in accordance with Equation 5a; or
       (b)  if paragraph 17(12)(d) or subsection 19(11) applies—calculated in accordance with Equation 6a; or
       (c)  given by section 96.
 =  initial carbon stock for the th stratum in tonnes of CO2‑e, given by section 93.

Calculating carbon stock for subsequent reporting periods for the stratum.
 (3) The carbon stock change for a stratum is to be calculated for subsequent reporting periods in which the stratum is referenced using the following formula:

   Equation 3b

  where:
 =  carbon stock change for the th stratum for the reporting period in tonnes of CO2‑e (t CO2‑e).
 =  closing carbon stock for the th stratum for the reporting period in tonnes of CO2‑e (t CO2‑e), calculated in accordance with Equation 5a or 6a or given by section 96.
 =  closing carbon stock for the th stratum for the most recent previous reporting period in tonnes of CO2‑e (t CO2‑e), and calculated in accordance with Equation 5a or 6a, or given by section 96.

Note: For Equation 3b,  for the most recent previous reporting period will be equal to , as given by Equation 5a or Equation 6a, as calculated for the most recent previous reporting period. If Equation 6a is being used, the amount  referred to in that equation will be the closing carbon stock for the reporting period that immediately precedes the most recent reporting period.
Calculating the standard error for the first reporting period for the stratum
 (4) When calculating the carbon stock change for the first reporting period in which a stratum is referenced, the standard error is to be calculated using the following formula:
   Equation 3c

  where:
 =  standard error for the carbon stock change for the th stratum for reporting period
