Division 2—Method for calculating net abatement amount
16 Summary
The carbon dioxide equivalent net abatement amount for a reporting period is worked out by adding together the activity abatement portion for the reporting period and any activity abatement portions, and legacy abatement portions, from previous reporting periods that have accrued and have not already been used to calculate the carbon dioxide equivalent net abatement amount.
17 Net abatement amount
The carbon dioxide equivalent net abatement amount for a reporting period, in tonnes CO2‑e, is worked out using the formula (equation 1):
where:
ANmeans the carbon dioxide equivalent net abatement amount for the reporting period, in tonnes CO2‑e.
A0 means activity abatement portion A0 for the reporting period, in tonnes CO2‑e, worked out in accordance with section 19.
AAcc means the amount, in tonnes CO2‑e, that is the sum of:
(a) each activity abatement portion that:
(i) has accrued from a previous reporting period (see subsection 19(3)); and
(ii) has not been used before to calculate the carbon dioxide equivalent net abatement amount; and
(b) if the project is a transitioning project—each legacy abatement portion that:
(i) has accrued from a previous reporting period (see subsection 41(2)); and
(ii) has not been used before to calculate the carbon dioxide equivalent net abatement amount.
Note: The no double counting test in section 15A of the Act means that abatement will only be reflected in the unit entitlement for a certificate of entitlement in respect of an eligible offsets project if it has not been reflected in the unit entitlement for another certificate or project.
Division 3—Method for calculating activity abatement portions
Subdivision A—Activity abatement portions
18 Summary
The activity abatement portions for a reporting period are worked out by dividing into 7 equal portions the abatement resulting from the project’s activities during the reporting period. One portion is used to calculate the carbon dioxide equivalent net abatement amount for the reporting period and the 6 other portions accrue over time to be used in subsequent reporting periods.
19 Calculation and accrual of activity abatement portions
Calculation of activity abatement portions

EB means the baseline emissions, in tonnes CO2‑e, worked out using equation 3.
EP means the project emissions, in tonnes CO2‑e, worked out using equation 9.
Note: The result of subtracting EP from EB is divided by 7 because this is the length of the crediting period for emissions avoidance projects (see section 69 of the Act).
(2) The activity abatement portions for the reporting period are taken to be zero if:
(a) the quantity of putrescible eligible waste that is processed during the reporting period is, or is taken to be, zero; or
(b) the reporting period is not included in a crediting period for the project.
Note: The quantity of putrescible eligible waste that is processed during a reporting period is worked out using equation 6.
Accrual of activity abatement portions
(3) The activity abatement portions for a reporting period accrue as follows:
(a) A1 accrues 1 year after the end of the reporting period;
(b) A2 accrues 2 years after the end of the reporting period;
(c) A3 accrues 3 years after the end of the reporting period;
(d) A4 accrues 4 years after the end of the reporting period;
(e) A5 accrues 5 years after the end of the reporting period;
(f) A6 accrues 6 years after the end of the reporting period.
20 Activity abatement portions for certain transitioning projects
If the ERF commencement day falls within the first reporting period for a transitioning project, the activity abatement portions for the reporting period are to be worked out as if the reporting period started on the ERF commencement day.
Note: Waste that is processed by a transitioning project before the ERF commencement day is not eligible waste (see the definition of eligible waste in section 5).
Subdivision B—Calculations relating to baseline emissions
21 Summary
The baseline emissions for a reporting period are the emissions that would have resulted if the eligible waste processed during the reporting period had entered landfill instead.
22 Baseline emissions

Division 4—Method for calculating legacy abatement portions
39 Summary
Legacy abatement portions are only relevant for transitioning projects.
The legacy abatement portions are worked out by dividing into 3 equal portions the abatement resulting from the transitioning project’s activities before this determination becomes the applicable methodology determination for the project. Legacy abatement portions only include abatement that has not been reflected in unit entitlement specified in a certificate of entitlement for the project.
The legacy abatement portions are used to calculate the carbon dioxide equivalent net abatement amount for the first reporting period for the project and subsequent reporting periods as the portions accrue.
40 Timing of calculation
Legacy abatement portions for a transitioning project are worked out once, during the first reporting period for the project.
41 Calculation and accrual of legacy abatement portions
(1) The legacy abatement portions for a transitioning project, in tonnes CO2‑e, are worked out using the formula (equation 21):
where:
ACFI,y means legacy abatement portion ACFI,1, ACFI,2 or ACFI,3, in tonnes CO2‑e.

(b) worked out under the applicable equation for the project that was in force for the purposes of calculating that amount for that reporting period.
ACFI,C means the amount that is the sum of the number of unit entitlement specified in each certificate of entitlement issued in respect of the project for each reporting period that ended before this determination became the applicable methodology determination for the project, in tonnes CO2‑e.
Note 1: ACFI,N will generally be the carbon dioxide equivalent net abatement amount included in the offsets report about the project for the reporting period that started when the declaration of the project as an eligible offsets project under section 27 of the Act took effect.
Note 2: The result of subtracting ACFI,C from ACFI,N is divided by 3 because this is the number of years remaining, after 1 July 2014, in the 7‑year period that started on 1 July 2010.
(2) The legacy abatement portions accrue as follows:
(a) ACFI,1 accrues 1 year after the start of the first reporting period for the project;
(b) ACFI,2 accrues 2 years after the start of the first reporting period for the project;
(c) ACFI,3 accrues 3 years after the start of the first reporting period for the project.
(3) Section 8 does not apply to a calculation under this section.
(4) In this section:
applicable equation, for a transitioning project in relation to a reporting period, means:
(a) if the Carbon Credits (Carbon Farming Initiative) (Avoided Emissions from Diverting Legacy Waste from Landfill for Process Engineered Fuel Manufacture) Methodology Determination 2012 was the applicable methodology determination for the project during the reporting period—equation 9 of that determination; or
(b) if the Carbon Credits (Carbon Farming Initiative) (Avoided Emissions from Diverting Legacy Waste through a Composting Alternative Waste Technology) Methodology Determination 2013 was the applicable methodology determination for the project during the reporting period—equation 11 of that determination; or
(c) if the Carbon Credits (Carbon Farming Initiative) (Diversion of Legacy Waste to an Alternative Waste Treatment Facility) Methodology Determination 2013 was the applicable methodology determination for the project during the reporting period—equation 15 of that determination; or
(d) if the Carbon Credits (Carbon Farming Initiative) (Enclosed Mechanical Processing and Composting Alternative Waste Treatment) Methodology Determination 2013 was the applicable methodology determination for the project during the reporting period—equation 11 of that determination.

(3) To avoid doubt, this section does not prevent the Regulator from taking action under the Act, or regulations or rules made under the Act, in relation to the project proponent’s failure to monitor a parameter as required by the monitoring requirements.
Note: Examples of action that may be taken include the following:
(a) if the failure constitutes a breach of a civil penalty provision in section 194 of the Act (which deals with project monitoring requirements), the Regulator may apply for a civil penalty order in respect of the breach;
(b) if false or misleading information was given to the Regulator in relation to the failure, the Regulator may revoke the project’s section 27 declaration under regulations or rules made for the purposes of section 38 of the Act;
(c) if the giving of false or misleading information in relation to the failure led to the issue of Australian carbon credit units, the Regulator may require all or some of those units to be relinquished under section 88 of the Act.
