(6) For the avoidance of doubt, if any of the proposed boundary of a carbon estimation area would result in the boundary overlapping the boundary of an exclusion area—then the boundary of the carbon estimation area must align with the boundary of the exclusion area.
Division 3.3 Project operation
3.7 Stocking density
Twelve months after the planting of a carbon estimation area, the stocking density of the planting must have the potential to achieve a minimum crown cover of 20% of the carbon estimation area.
Note The potential to achieve crown cover can be demonstrated by multiplying the stocking density (trees per hectare) by the mature crown area (in hectares).
3.8 Biomass harvesting exclusion

Part 4 The net abatement amount
Division 4.1 The net abatement amount
4.1 The net abatement amount
Note See paragraph 106(1)(c) of the Act.
For an eligible offsets project to which this Determination applies, the carbon dioxide equivalent net abatement amount in relation to a reporting period for the project is taken to be the change in carbon stock for the project area less the project emissions—see section 4.15.
Division 4.2 Calculations—Preliminary
4.2 General
In this Part:
(a) all calculations are in respect of activities undertaken, or outcomes achieved, during a reporting period for the eligible offsets project; and
(b) if a calculation refers to a factor or parameter prescribed in the NGER Measurement Determination or the NGER Regulations, the person carrying out the calculations must apply, to the whole reporting period, the NGER Measurement Determination or NGER Regulations in force at the time that the offsets report was submitted or was required to be submitted, whichever is earlier.
4.3 Greenhouse gas assessment boundary
When making calculations under this Part:
(a) the carbon pools and emission sources and the corresponding greenhouse gases in the following table must be taken into account; and
(b) no other gases, carbon pools or emission sources may be taken into account.
Table of gases accounted for in the abatement calculations.
| Carbon pools and emission sources | Greenhouse gas |
|---|---|
| Live above-ground biomass | Carbon dioxide (CO2) |
| Live below-ground biomass | Carbon dioxide (CO2) |
| Dead plant material and debris | Carbon dioxide (CO2) |
| Fuel use | Methane (CH4)Nitrous oxide (N2O)Carbon dioxide (CO2) |
| Fire | Methane (CH4)Nitrous oxide (N2O)Carbon dioxide (CO2) |
4.4 Baseline for the project
For the purposes of paragraph 106(4)(f) of the Act:
(a) the baseline for a project in relation to a reporting period is the carbon stock that the carbon estimation areas for the project would have had in the absence of the project if the land use and management had continued as they were during the baseline period for the project; and
(b) the baseline amount is taken to be zero.
Note The baseline amount will not normally be precisely zero for land that has the potential to achieve forest cover, but will be small enough to be taken to be zero for the purposes of this Determination.
4.5 Potential to achieve forest cover required for calculations
(1) The carbon stock of a carbon estimation area that does not yet have the potential to achieve forest cover must be recorded as zero.
Note Potential to achieve forest cover is demonstrated by having sufficient planting density or stocking density, in stems per hectare, to achieve 20% crown cover at maturity.
(2) For the purposes of calculating carbon stock, the modelling commencement date in the RMT must be the date on which the last planting occurred within the carbon estimation area as demonstrated by:
(a) remotely-sensed imagery; or
(b) other documented evidence that demonstrates to the satisfaction of the Regulator the planting of the carbon estimation area.
4.6 Changes in carbon estimation areas
All calculations under this Part must be done on the basis of the carbon estimation areas of the project as they stood at the end of the current reporting period.
4.7 Use of Reforestation Modelling Tool (RMT)
(1) The RMT must be used to determine:
(a) the initial carbon stock for each carbon estimation area (View image in the official source) at the beginning of the reporting period;
(b) the carbon stock for a carbon estimation area at the end of the reporting period (View image in the official source);
(c) the tree layer carbon emitted to the atmosphere for each month of a reporting period (View image in the official source);
(d) the debris layer carbon emitted to the atmosphere for each month of a reporting period (View image in the official source); and
(e) the emissions from fire within a carbon estimation area (View image in the official source).
(2) To determine the parameters specified in subsection (1), the project proponent must collect and provide and record input data to the RMT in the format required by the tool including the following information:
(a) the area and modelling point latitude and longitude data for each carbon estimation area; and
(b) forest management information as specified in section 5.5 for each carbon estimation area.
Model settings for RMT
(3) The ‘mixed species environmental planting’ species setting in the RMT must be used in conjunction with the information specified in subsection (2) for the purposes of carrying out the calculations in Division 4.3.
(4) The regime setting appropriate for the establishment method used in the RMT must be selected and must be one of the following:
(a) ‘Non-harvested regime, planting density : direct seeding’;
(b) ‘Non-harvested regime, planting density : high (>= 1,200 stems/ha)’;
(c) ‘Non-harvested regime, planting density : low (<= 800 stems/ha)’;
(d) ‘Non-harvested regime, planting density : medium (~ 1,000 stems/ha)’.
Division 4.3 Calculation of carbon stock change
4.8 Step 1—Calculate the initial carbon stock of the project area
Note This step is relevant only for a pre-existing project, where the planting began before the declaration date. The carbon stock that had accumulated by that date must be calculated because the project proponent is not entitled to credits for it. As the RMT is updated, it is possible that the revised calculations of the initial carbon stock could change the output significantly. This Division takes that possibility into account.
(1) For the first offsets report, the initial carbon stock (View image in the official source) is:
(a) for a project other than a pre-existing project—zero; and
(b) for a pre-existing project—the carbon stock for the project area at the declaration date.
(2) Initial carbon stock must be re-calculated for each reporting period, using the current version of the RMT, as follows:
| Equation 1a |
|---|
Where:
 = initial carbon stock (in tonnes C) for the project area, calculated for the purposes of the current reporting period (rc).
 = carbon stock (in tonnes C) for the ith carbon estimation area within the project area on the declaration date, determined using the RMT as it stood at the end of the current reporting period (rc).
i = the ith carbon estimation area, where n is the total number of carbon estimation areas within the project area.
4.9 Step 2—Calculate the carbon stock of the project area at the end of a reporting period
The carbon stock for the project area must be calculated at the end of each reporting period as follows:
| Equation 1b |
|---|
Where:
 = carbon stock (in tonnes C) for the project area at the end of the current reporting period (rc).
 = carbon stock (in tonnes C) for the ith carbon estimation area within the project area at the end of the current reporting period (rc), determined using the RMT.
i = the ith carbon estimation area, where n is the total number of carbon estimation areas within the project area.
4.10 Step 3—Calculate the carbon stock change for the project area
(1) The carbon stock change for the project area for the first reporting period must be calculated as follows:
| Equation 2a |
|---|
Where:
 = carbon stock change (in tonnes C) for the project area for the first reporting period (rc).
 = carbon stock (in tonnes C) for the project area at the end of the first reporting period (rc)—see equation 1b.
 = initial carbon stock (in tonnes C) for the project area, calculated for the purposes of the first reporting
period (rc)—see equation 1a.
(2) The carbon stock change for the project area for subsequent reporting periods must be calculated as follows:
| Equation 2b |
|---|
Where:
 = carbon stock change (in tonnes C) for the project area for the current reporting period (rc).
 = carbon stock (in tonnes C) for the project area at the end of the current reporting period (rc)—see equation 1b.
 = carbon stock (in tonnes C) for the project area at the end of the previous reporting period (rp)—see equation 1b.
 = initial carbon stock (in tonnes C) for the project area, calculated for the purposes of the current reporting period (rc)—see equation 1a.
 = initial carbon stock (in tonnes C) for the project area, calculated for the purposes of the previous reporting period (rp)—see equation 1a.
4.11 Step 4—Convert the carbon stock change to CO2‑equivalent (CO2-e)
The carbon stock change in CO2-e for the project area for the reporting period is calculated as follows:
| Equation 3 |
|---|
Where:
 = carbon stock change (in tonnes CO2\-e) for the project area for the current reporting period (rc).
 = carbon stock change (in tonnes C) for the project area for the current reporting period (rc)—see equation 2b.
 \= global warming potential of carbon dioxide as specified in the NGER Regulations.
Division 4.4 Calculation of project emissions
4.12 Step 1—Calculate methane and nitrous oxide emissions
(1) Emissions of methane due to biomass burning for the project for the reporting period are calculated as follows:
| Equation 4 |
|---|
Where:
 = emissions of CH4 (in tonnes CO2\-e) from biomass burning for the project area (EP) for the current reporting period (rc).
 = tree layer carbon (in tonnes C) for each carbon estimation area (i), emitted to the atmosphere for each month (t) of the current reporting period (rc) determined using the RMT.
 \= debris layer carbon (in tonnes C) for each carbon estimation area (i), emitted to the atmosphere for each month (t) of the current reporting period (rc) determined using the RMT.
 = —derived constant calculated from the product of carbon mass, emission factor and molecular mass fraction.
 \= global warming potential of methane as specified in the NGER Regulations.
i = the ith carbon estimation area, where n is the total number of carbon estimation areas within the project area.
t = month in the current reporting period, where tp is the last month of the previous reporting period and tc is the last month of the current reporting period.
(2) Emissions of nitrous oxide due to biomass burning for the reporting period are calculated as follows:
| Equation 6 |
|---|
Where:
 = emissions of N2O (in tonnes CO2\-e) from biomass burning for the project for the current reporting period (rc).
 = tree layer carbon (in tonnes C) for each carbon estimation area (i), emitted to the atmosphere for each month (t) of the reporting period determined using the RMT as it stood at the end of the current reporting period (rc).
 \= debris layer carbon (in tonnes C) for each carbon estimation area (i), emitted to the atmosphere for each month (t) of the reporting period determined using the RMT as it stood at the end of the current reporting period (rc).
 = —derived constant, calculated from the product of carbon mass, emission factor and molecular mass fraction.
 \= global warming potential of nitrous oxide as specified in the NGER Regulations.
i = the ith carbon estimation area, where n is the total number of carbon estimation areas within the project area.
t = month in the current reporting period, where tp is the last month of the previous reporting period and tc is the last month of the current reporting period.
(3) Total emissions due to biomass burning for the reporting period are calculated as follows:
| Equation 7 |
|---|
Where:
 = total emissions (in tonnes CO2\-e) from biomass burning for the project for the current reporting period (rc)
 = emissions of CH4 (in tonnes CO2\-e) from biomass burning for the project for the current reporting period (rc)—see Equation 4.
 = emissions of N2O (in tonnes CO2\-e) from biomass burning for the project for the current reporting period (rc)—see Equation 6.
4.13 Step 2—Calculate emissions from fuel use
(1) Emissions from fuel use for the project for the current reporting period are calculated in accordance with this section.
(2) The quantity of fuel use for each fuel type (f) for the project for the current reporting period is calculated as follows:
| Equation 8 |
|---|
Where:
 = quantity of fuel type (f) (in kilolitres) combusted within the current reporting period (rc).
 = quantity of fuel type (f) (in kilolitres) combusted in month (t) for:

(b) transport energy purposes.
t = month in the current reporting period, where tp is the last month of the previous reporting period and tc is the last month of the current reporting period.
Note Where fuel information is provided on an annual basis the monthly data can be determined by dividing the annual figure by twelve and the result substituted for View image in the official source.
(3) The fuel emissions for each fuel type (f) and each greenhouse gas (carbon dioxide, nitrous oxide and methane) for the reporting period is calculated as follows:
| Equation 9 |
|---|
Where:
 = fuel emissions for each fuel type (f) and each greenhouse gas (j) for the current reporting period (rc).
 = quantity of fuel type (f) (in kilolitres) combusted within the current reporting period (rc)—see Equation 8.
 = energy content factor of fuel type (f) (gigajoules per kilolitre), as prescribed in Schedule 1 of the NGER Measurement Determination.
 = emission factor for gas type (j) (carbon dioxide, nitrous oxide and methane) for fuel type (f) (in kilograms CO2‑e per gigajoule) as prescribed in Schedule 1 of the NGER Measurement Determination.
(4) The total emissions from fuel use for the project for the reporting period are calculated as follows:
| Equation 10 |
|---|
Where:
EP,E,rc = total project fuel emissions (in tonnes CO2\-e) for the current reporting period (rc).
EP,f,j,rc = fuel emissions for each fuel type (f) and each greenhouse gas (j) (carbon dioxide, nitrous oxide and methane) (in tonnes CO2\-e) for the current reporting period (rc)—see Equation 9.
f = denotes the fth type of fuel, where p is the number of different types of fuel.
j = denotes the jth type of greenhouse gases (carbon dioxide, methane or nitrous oxide) emitted where q is the number of different types of greenhouse gases emitted from combustion of fuel type (f).
4.14 Step 3—Calculate total project emissions
The project emissions in CO2-e for the project for a reporting period are the sum of the total emissions due to biomass burning as specified in section 4.12 and the total emissions from fuel use as specified in section 4.13.
Division 4.5 Calculating the carbon dioxide equivalent net abatement amount
4.15 Calculating the carbon dioxide equivalent net abatement amount
Note See paragraph 106(1)(c) of the Act.
For an eligible offsets project to which this Determination applies, the carbon dioxide equivalent net abatement amount for the project in relation to a reporting period is taken to be the amount (View image in the official source) calculated as follows:
| Equation 11 |
|---|
Where:
 = project abatement (in tonnes CO2‑e) for the current reporting period (rc).
 = carbon stock change (in tonnes CO2\-e) for the project for the current reporting period (rc)—see Equation 3.
 = total project emissions from biomass burning (in tonnes CO2‑e) for the current reporting period (rc)—see Equation 7.
 = total project fuel emissions (in tonnes CO2\-e) for the current reporting period (rc)—see Equation 10.
