20 Calculation of carbon stock changes by post-1989 forest land participants

• (1) A post-1989 forest land participant must calculate the emissions or removals from each carbon accounting area covered by an emissions return for an emissions return period by determining the carbon stock change in the carbon accounting area in accordance with the following formula:

  CS_change = ∑(CS_closing) − ∑(CS_opening)

  where—

  CS_change

  is the carbon stock change for the carbon accounting area in the emissions return period

  CS_closing

  is the carbon stock of each sub-area within the carbon accounting area at the end of the emissions return period, calculated in accordance with regulation 21

  CS_opening

  is, subject to regulation 20A, the carbon stock of each sub-area within the carbon accounting area at the beginning of the emissions return period, calculated in accordance with regulation 21.

  (2) If the carbon stock change for a carbon accounting area in an emissions return period is—

  • (a) positive, the change is a removal; or

  • (b) negative, the change is an emission.

  (3) This regulation is subject to regulation 20A.
