Part 2—Savanna fire management projects
8 Savanna fire management projects
(1) For paragraph 106(1)(a) of the Act, this determination applies to an offsets project that:
(a) aims to reduce the emission of methane and nitrous oxide from fire by using fire management primarily in the early dry season; and
(b) is carried out in a savanna that includes land in either or both of the following:
(i) the high-rainfall zone;
(ii) the low-rainfall zone.
(2) A project covered by subsection (1) is a savanna fire management project.
Part 3—Project requirements
Division 1—General
9 General
For paragraph 106(1)(b) of the Act, to be an eligible offsets project, a savanna fire management project must meet the requirements in this Part.
Division 2—Additionality
10 Requirement in lieu of newness requirement
(1) For subparagraph 27(4A)(a)(ii) of the Act, the requirement in subsection (2) is in lieu of the newness requirement for a project to which this determination applies.
(2) The project must be a savanna fire management project.
11 Requirement in lieu of regulatory additionality requirement
(1) For subparagraph 27(4A)(b)(ii) of the Act, the requirement in subsection (2) is in lieu of the regulatory additionality requirement for a savanna fire management project.
(2) A project area must not include land where fire management for the primary purpose of reducing emissions from fire is required to be carried out by or under a law of the Commonwealth, a State or a Territory.
Division 3—Project area
Note A savanna fire management project may be declared with one or more project areas.
For reporting purposes, the proponent may choose to divide the project and give the project areas different reporting schedules, provided that they all satisfy the reporting period requirements under the Act.
However, whatever the reporting schedule for each project area, the method under this determination requires that the abatement calculations are made for each year of the crediting period, and reported on.
12 Requirement to be in high or low rainfall zone
Every part of each project area must be:
(a) in the high rainfall zone; or
(b) in the low rainfall zone.
Note A project may be carried out on both land in the high rainfall zone and land in the low rainfall zone.
13 Requirement to have specified vegetation fuel types
A part of a project area that is in:
(a) the high rainfall zone; or
(b) the low rainfall zone;
must contain at least one of the vegetation fuel types listed for that zone in Schedule 1.
14 When separate project areas in different rainfall zones are needed
A project area for which the project proponent intends to calculate net annual project abatement without using SavBAT 2 must be wholly within either the high rainfall zone or the low rainfall zone.
15 Variations to project areas
(1) This section applies to a savanna fire management project if:
(a) the Regulator has declared that the project is an eligible offsets project; and
(b) the project proponent proposes to vary the declaration after lodging the first offsets report.
(2) The project, as it is proposed to be varied, is not an eligible offsets project if it would include a project area that overlaps, but is not identical with, a project area identified in the declaration.
Note 1 The effect of this section is that project areas may be added to a project, but that an existing project area cannot be divided, or increased or reduced in size.
Note 2 In the case of a project to which the Regulator approved the application of this determination under subsection 130(2) of the Act, the declaration would identify the project area of the project under the relevant earlier savanna-burning determination.
Division 4—Project activity
16 Project activity
(1) The project must be one in which:
(a) fire management is carried out in each project area in the early dry season; and
(b) fire management may also be carried out in each project area in the late dry season.
(2) The fire management must be carried out with the intention of ensuring that, in each project area, the early dry season burn for a year in the crediting period is greater than the average early dry season burn during the baseline period.
(3) The fire management may be combined with natural or constructed barriers to extinguish fires or reduce their spread.
(4) The project must not be one in which the project proponent attempts to increase the proportion of the annual area burnt by all fires in a project area in the early dry season by a method other than fire management.
Example The project cannot be one in which stocking densities are deliberately increased in or adjacent to the project in the late dry season for the primary purpose of reducing fuel loads.
(5) For subsection (2), the early dry season burn for a particular project area and for a particular calendar year is the ratio of the area burnt within that project area during the early dry season to the total area burnt within that project area during that year.
Part 4—Net abatement amount
Division 1—Preliminary
17 Operation of this Part
For paragraph 106(1)(c) of the Act, this Part specifies the method for working out the carbon dioxide equivalent net abatement amount for a reporting period for a savanna fire management project that is an eligible offsets project.
18 Simplified outline
This section sets out a simplified outline of the method specified in this Part.
• First, the project proponent must develop and validate a vegetation fuel type map in accordance with Division 2. There is an exception to this requirement for projects that are transitioning from an earlier savanna-burning determination, in which case the project proponent is able to rely on existing vegetation maps for those parts of the project that are transitioning.
• Second, the project proponent must calculate the carbon dioxide equivalent net abatement amount for the relevant reporting period—see Division 3 and, where the calculation is to be performed manually, see also Division 4. This involves the following:
(a) The carbon dioxide equivalent net abatement amount, , is calculated by summation of the adjusted net annual project abatement, , for all years in the relevant reporting period—see Subdivision 1 of Division 3.
(b) The adjusted net annual project abatement, , is calculated, for each year , as a function of the net annual abatement for that year, , and the ‘uncertainty buffer’ for the previous year, —see Subdivision 2 of Division 3.
(c) The net annual abatement for year , , can be calculated either by using the offsets reporting functionality of SavBAT 2 or, in many cases, by following the steps set out in Division 4—see Subdivision 3 of Division 3.
(d) The net annual abatement for year , , is a function of several variables. One variable is the annual fossil fuel emissions in calendar year for fossil fuel type and greenhouse gas , , which must be calculated manually, in accordance with Subdivision 4 of Division 3, regardless of whether is calculated using SavBAT 2 or by following the steps set out in Division 4.
• The project proponent is only able to calculate the net annual abatement for year , , without using SavBAT 2, if the relevant project area is wholly within either the high rainfall zone or the low rainfall zone.
• If the project consists of more than one project area, then:
(a) the project proponent must carry out the steps set out in Division 3 and, where appropriate, Division 4 separately for each project area; and
(b) the carbon dioxide equivalent net abatement amount for the reporting period is the sum of the carbon dioxide equivalent net abatement amounts, , for each project area.
19 Overview of gases accounted for in abatement calculations
When making calculations under this Part:
(a) the greenhouse gases listed in Table A must be taken into account in relation to the specified project activities; and
(b) no other gases or project activities may be taken into account.

20 References to factors and parameters from external sources
(1) If SavBAT 2, or a calculation in this determination, includes a factor or parameter that is defined or calculated by reference to another instrument or writing, the factor or parameter to be used for a reporting period is the factor or parameter referred to in, or calculated by reference to, the instrument or writing as in force at the end of the reporting period.
(2) Subsection (1) does not apply if:
(a) the determination specifies otherwise; or
(b) it is not possible to define or calculate the factor or parameter by reference to the instrument or writing as in force at the end of the reporting period.

Note A single vegetation fuel type map may cover more than one project area.
(6) The project proponent must assign to each pixel a code as follows:
(a) if the area represented by the pixel is dominated by a particular vegetation fuel type—the code for that vegetation fuel type;
(b) otherwise—‘ineligible’.

(a) greater than the area of land occupied by any other vegetation fuel type; and
(b) greater than the area of land that is not occupied by a vegetation fuel type.
Transitional rule
(8) If:
(a) a person was the project proponent for a project that was declared eligible under an earlier savanna-burning determination; and
(b) a vegetation map was validated in accordance with that determination (the transitioning vegetation map); and
(c) the Regulator approves the application of this determination to that project under section 130 of the Act;
then:
(d) the transitioning vegetation map is taken to be a vegetation fuel type map that complies with this Division; and
(e) the vegetation class in the transitioning vegetation map referred to in Table B is taken to refer to the corresponding code referred to in the table.

(a) applying Equation 1 to each project area; and
(b) summing each of the values so calculated.
Subdivision 2—Calculation of adjusted net annual project abatement
25 Outline
This section outlines the calculation of the adjusted net annual project abatement, , that is performed under this Subdivision.
• The adjusted net annual project abatement, , is calculated by adjusting the net annual project abatement, , to manage the risk of the project containing some year(s) in which emissions are higher than the average annual baseline emissions. This is achieved by means of a ‘uncertainty buffer’, , which is added to in years in which net annual abatement is greater than zero and subtracted from in years in which net annual project abatement is less than zero. The value of the uncertainty buffer is calculated at the end of each calendar year. At the beginning of the project, including transitioning projects, the value of the uncertainty buffer is zero.
• The amount stored in the uncertainty buffer is capped at a maximum, , which is equal to 5 per cent of the average annual baseline emissions. The uncertainty buffer is only added to if the uncertainty buffer in the preceding year is less than the maximum value, and where net annual project abatement is greater than zero.
• If SavBAT 2 includes the functionality to calculate adjusted net annual project abatement, the project proponent may either use SavBAT 2 to perform the calculation, or may perform it manually. If SavBAT 2 does not include that functionality, the project proponent must perform the calculation manually, in accordance with this Subdivision.
26 Calculation of adjusted net annual project abatement
(1) Subject to subsection (2), for each calendar year in the crediting period, the project proponent must calculate adjusted net annual project abatement, , in accordance with this section.
(2) The project proponent may use SavBAT 2 to calculate adjusted net annual project abatement if SavBAT 2 includes the functionality to perform that calculation.
