21 Calculation of carbon stock

• (1) For the purposes of regulation 20, the carbon stock of a sub-area must be calculated by—

  • (a) using—

    • (i) table 1 or 2 of Schedule 6 for non-FMA participants, or the table required under regulation 22E for FMA participants, to calculate the forest carbon stock of the sub-area other than from any above ground residual wood and below ground roots from previously cleared trees referred to in subparagraph (ii) (T₁); and

    • (ii) if relevant, table 3 or 4 of Schedule 6 for non-FMA participants, or the table required under regulation 22E for FMA participants, to calculate the carbon stock of the sub-area from above ground residual wood and below ground roots from previously cleared trees that are to be treated as decaying on the land under regulation 22(h) (T₂); and

  • (b) adding together each of the figures for carbon stock referred to in subclause (1)(a) (T₁ + T₂).

  (2) The following formula must be used to calculate the carbon stock of a sub-area under subclause (1)(a)(i):

  A × C = T₁

  where—

  A

  is the area, in hectares, of land in the sub-area

  C

  is the figure for carbon stock per hectare from table 1 or 2 in Schedule 6 for non-FMA participants, or the table required under regulation 22E for FMA participants, that reflects—

  • (a) the forest type of the sub-area; and

  • (b) the age of the trees; and

  • (c) if the forest type is Pinus radiata and a table in Schedule 6 is being used, the region in which the sub-area is located

  T₁

  is the forest carbon stock of the sub-area, other than from any above ground residual wood and below ground roots from previously cleared trees, in tonnes of carbon dioxide.

  (3) The following formula must be used to calculate the carbon stock of a sub-area under subclause (1)(a)(ii):

  A × C × Y/10 = T₂

  where—

  A

  is the area, in hectares, of land in the sub-area

  C

  is the figure for carbon stock per hectare in the above ground residual wood and below ground roots from cleared trees from table 3 or 4 in Schedule 6 for non-FMA participants, or the table required under regulation 22E for FMA participants, that reflects—

  • (a) the forest type of the residual wood decaying on the sub-area; and

  • (b) the age of the trees when cleared; and

  • (c) where the forest type cleared was Pinus radiata and a table in Schedule 6 is being used, the region in which the sub-area is located

  Y

  is 10 minus the number of years up to 10 since the trees were cleared (including the year in which the trees were cleared)

  T₂

  is the carbon stock of the sub-area from above ground residual wood and below ground roots from any cleared trees, in tonnes of carbon dioxide.

  (4) Application of the tables in Schedule 6 or any participant-specific table required under regulation 22E is subject to the rules in regulation 22.
