2 Commencement
This determination commences on the day after it is registered.
3 Authority
This determination is made under subsection 106(1) of the Carbon Credits (Carbon Farming Initiative) Act 2011.
4 Duration
This determination remains in force for the period that:
(a) begins when this determination commences; and
(b) ends on the day before this instrument would otherwise be repealed under subsection 50(1) of the Legislation Act 2003.
5 Definitions
In this determination:
Act means the Carbon Credits (Carbon Farming Initiative) Act 2011.
baseline emissions has the meaning given by subsection 17(1).
baseline emissions intensity has the meaning given by subsection 17(2).
cotton area, in relation to given year and project area:
(a) means the area of land within the project area that is the aggregate of the fields that were fully planted with cotton and irrigated; and
(b) for a year in the crediting period—does not include any area of land on which the residue remaining in the field after the harvest of cotton is burnt.
Note: The cotton area is a subset of the project area and is expected to change on an annual basis due to a range of factors, including water availability and rotational cropping. The cotton area does not include parts of the project area on which cotton was not planted in a given year. The cotton area must include all fields that were fully planted with cotton and irrigated. This does not mean that partly planted fields must be excluded from the cotton area: the project area can be re-stratified to ensure that all parts of the project area on which cotton was planted and irrigated are included in the cotton area. The cotton area does not need to have a single boundary.

(i) increases the nitrogen available to the plant; or
(ii) reduces nitrogen losses from the soil; or
(iii) does both subparagraph (i) and (ii);
(e) a combination of the modifications specified in paragraphs (a)–(d).
Division 4—Emissions intensity reference period
11 Determining the emissions intensity reference period
(1) A project area in an irrigated cotton project must have an emissions intensity reference period consistent with the requirements in this Part.
(2) The emissions intensity reference period is the 6 year period starting from the day 6 years before the first day of the crediting period.
(3) The emissions intensity reference period must include a minimum of 3 years in which the project area included a cotton area.
(4) In order for a year to count for the purposes of subsection (3), the information required under Divisions 3 and 4 of Part 5 must be available for that year, and the lint yield for that year must not be zero.
(5) If information required under Divisions 3 and 4 of Part 5 is available for a year during the emissions intensity reference period in which the project area included a cotton area, and the lint yield for that year is not zero, that year must be included in the calculation of baseline emissions intensity in accordance with subsection 17(2).
(6) If the requirements in subsection (3) and subsection (4) are not met in the period mentioned in subsection (2), the emissions intensity reference period may be extended up to a maximum of 3 times, by moving the start date to a year earlier until the requirements are satisfied.
Note: Under this subsection, the emissions intensity reference period may need to be extended to 7, 8 or 9 years for the project to have 3 years of relevant cotton data and thus be an eligible offsets project.
Division 5—Project area requirements
12 Project area
Restriction on project area
(1) A project area must consist only of one or more fields on the whole of which cotton could have been grown since the beginning of the emissions intensity reference period.
Restriction on varying project area
(2) Subsection (3) applies if the project proponent applies to vary a declaration under section 27 of the Act in relation to the project area.
(3) The declaration as proposed to be varied must not include a project area that overlaps, but is not identical with, a project area identified in the declaration being varied.
Note: Project areas may be added to a project, but existing project areas cannot be divided, or increased or reduced in size.
13 Stratification
(1) The project proponent must produce a map which stratifies a project area into fields, and shows the cotton area, for each year in:
(a) the emissions intensity reference period; and
(b) the crediting period.
Note: The maps produced are required to be provided to the Regulator under sections 8 and 22.
(2) Each field identified in a map produced for the purposes of subsection (1) must be issued a unique identifier.
(3) For the avoidance of doubt, a map produced for the purposes of subsection (1) does not need to align with calendar or financial years.
Note: For the purposes of administrative simplicity, project proponents are encouraged to align the 12 month period covered by their annual map with the relevant cotton growing season rather than a calendar or financial year.
14 Mapping format and precision
(1) A map produced for the purposes of subsection 13(1) must be in a digital Geographic Information System format.
(2) The boundary of a field identified in accordance with section 13 must have a horizontal accuracy either:

Note: The Standard mentioned in paragraph (b) is available at: www.icsm.gov.au.
Part 4—Net abatement amount
Division 1—The net abatement amount
15 Method for calculating the net abatement amount
(1) 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 an irrigated cotton project that is an eligible offsets project.
(2) For each project area and for each year in the reporting period, calculate the annual project area abatement amount, in t CO2-e, in accordance with the following formula:
Image unavailable in extracted text
Note: The terms baseline emissions and project emissions are defined, for each project area and each year of the reporting period, in Division 2 and Division 3 respectively.
(3) For the reporting period, the carbon dioxide equivalent net abatement amount is the sum of all annual project area abatement amounts greater than zero.
Note: Annual project area abatement amounts that are less than zero must be reported, but are not deducted from the carbon dioxide equivalent net abatement amount. This treatment of negative annual project area abatement amounts is possible from a greenhouse gas accounting perspective because of the variance discount applied to the baseline, which reduces positive annual project area abatement amounts (see Division 2).
16 Gases accounted for in abatement calculations
(1) The following table provides an overview of the greenhouse gases and emissions sources that are relevant to working out the carbon dioxide equivalent net abatement amount for an irrigated cotton project.
(2) For a year, green manure residue is only relevant to working out the carbon dioxide equivalent net abatement amount for an irrigated cotton project if:
(a) the green manure crop is planted on an area of land that is a part of the cotton area in the year; and
(b) the green manure crop is planted prior to the cotton planting in the year; and
(c) there are no other crops planted between the green manure crop and the cotton planting in the year.
(3) For a year, synthetic fertiliser is only relevant to working out the carbon dioxide equivalent net abatement amount if the synthetic fertiliser is applied:
(a) after the harvest of the crop previous to the cotton planting; and
Note: The crop previous to the cotton planting could be a cotton crop, or a crop grown in rotation with cotton.
(b) before the harvest of the cotton area in the year.
Division 2—The baseline emissions
Note: Calculations described in this Division are performed using the Irrigated Cotton Calculator.
17 The baseline emissions
(1) For each year in the reporting period and for each project area, the baseline emissions is the product of:
(a) the baseline emissions intensity; and
(b) the lint yield in that year in the reporting period;
minus the variance discount, as specified in section 18.
(2) In this section, the baseline emissions intensity, in t CO2-e per tonne of lint yield, of the project area is the amount calculated by:
(a) for each year in the emissions intensity reference period in which information required under Divisions 3 and 4 of Part 5 is available and the lint yield is not zero:
Note: Subsection 11(5) requires the calculations in subsection 17(2) to be performed for each year in which information required under Divisions 3 and 4 of Part 5 is available and the lint yield is not zero.
(i) determining emissions, in t CO2\-e, from each of the emissions sources specified in section 16:
(A) for synthetic fertiliser—by using methods consistent with those used in the National Inventory Report; and
(B) for green manure when it is relevant to working out the carbon dioxide equivalent net abatement amount—by multiplying the emissions intensity of green manure residue, in t CO2\-e per hectare, calculated using methods consistent with those used in the National Inventory Report and assuming a yield of 2 tonnes of dry matter per hectare, by the number of hectares of green manure in the year; and
(ii) summing the amounts calculated in accordance with subparagraph (i); and
(iii) dividing the amount calculated in accordance with subparagraph (ii) by the lint yield of that year, in tonnes; and
(b) averaging the values obtained in accordance with subparagraph (2)(a)(iii).
18 The variance discount
The variance discount is 6.5% of the product of the amounts referred to in paragraph 17(1)(a) and paragraph 17(1)(b).
Note: A variance discount of 6.5% is applied to the baseline to ensure that the carbon dioxide equivalent net abatement amount excludes emissions reductions that may have occurred due to natural variation (see also subsection 15(3)). Accordingly, for a year in the reporting period, baseline emissions are 0.935 multiplied by the product of the baseline emissions intensity and the lint yield in that year.
Division 3—The project emissions
Note: Calculations described in this Division are performed using the Irrigated Cotton Calculator.
19 The project emissions
(1) For a project area, for each year in the reporting period, the project emissions is the sum of:
(a) the emissions from synthetic fertiliser, in t CO2-e, as determined using methods consistent with those used in the National Inventory Report; and
(b) the emissions from green manure in t CO2-e, in each year in which it is relevant to working out the carbon dioxide equivalent net abatement amount.
(2) The parameter specified in paragraph (1)(b) must be calculated by multiplying the emissions intensity of green manure residue, in t CO2-e per hectare, by the number of hectares of green manure in the year.
(3) The emissions intensity of green manure residue specified in subsection (2) must be calculated using methods consistent with those used in the National Inventory Report and assuming a yield of 2 tonnes of dry matter per hectare.
Division 4—Use of Irrigated Cotton Calculator
20 Requirement to use Irrigated Cotton Calculator
(1) When performing calculations for the purposes of this Part:
(a) the calculations must be performed using the Irrigated Cotton Calculator for each project area and for each year in the reporting period; and
