(ii) for a measurement time interval in an operating measurement period or a reporting period—those that have no observable effect on the consumption of operating relevant energy for the implementation in the measurement time interval.

sub‑method means one of the sub‑methods set out in Part 4.

6 Meaning of baseline relevant energy

(1) The baseline relevant energy for an implementation is:

(a) fuel and electricity consumed by existing energy‑consuming implementation equipment; and

(b) if the emissions from the consumption of fuel or electricity by existing interactive equipment is likely to change as a result of the implementation and the project proponent has not identified the change as an interactive effect—fuel and electricity consumed by the interactive equipment; and

(c) if the project proponent chooses—the consumption of fuel and electricity by existing co‑metered equipment.

Note 1: Consumption that is impractical or disproportionally costly to measure may be excluded under section 32.

Note 2: A change in consumption which falls within the definition of interactive effect but which the project proponent has not identified as an interactive effect is covered by paragraph (b).

(2) However, if electricity generated at the site of the implementation is consumed by existing implementation equipment, existing interactive equipment or existing co‑metered equipment, only one of the following, as chosen by the project proponent, is baseline relevant energy for the implementation:

(a) the electricity generated at the site consumed by the equipment;

(b) fuel used to generate that electricity.

7 Meaning of operating relevant energy

(1) The operating relevant energy for an implementation is:

(a) fuel and electricity consumed by equipment covered by the baseline relevant energy for the implementation; and

(b) fuel and electricity consumed by implementation equipment installed as part of the implementation.

Note: If the implementation involves removing implementation equipment, the fuel and electricity consumption by that equipment will be zero for the purposes of determining operating relevant energy for the implementation.

(2) However, if electricity generated at the site of the implementation is consumed by equipment mentioned in subsection (1), only one of the following, as chosen by the project proponent, is operating relevant energy for the implementation:

(a) the electricity generated at the site consumed by the equipment;

(b) fuel used to generate that electricity.

8 Meaning of effective range for an independent variable

(1) The effective range of an independent variable for an implementation covered by sub‑method 1 in a reporting period is the range of measured values for the independent variable used in the regression analysis to develop the baseline emissions model for the implementation.

(2) The effective range of an independent variable for an implementation covered by sub‑method 2 in a reporting period, which was used in both the baseline emissions model and the operating emissions model for the implementation for the reporting period, is the range of measured values for the independent variable between:

(a) the highest minimum value for the independent variable used in the regression analysis to develop an emissions model for the implementation, which is the higher of:

(i) the minimum value for the independent variable used in the regression analysis to develop the baseline emissions model for the implementation; and

(ii) the minimum value for the independent variable used in the regression analysis to develop the operating emissions model for the implementation for the reporting period; and

(b) the lowest maximum value for the independent variable used in the regression analysis to develop an emissions model for the implementation, which is the lower of:

(i) the maximum value for the independent variable used in the regression analysis to develop the baseline emissions model for the implementation; and

(ii) the maximum value for the independent variable used in the regression analysis to develop the operating emissions model for the implementation for the reporting period.

(3) The effective range of an independent variable for an implementation covered by sub‑method 2 in a reporting period, which was used only in the baseline emissions model or only in the operating emissions model for the implementation for the reporting period, is the range of measured values for the independent variable used in the regression analysis to develop the emissions model.

Note: Under section 25 no values of independent variables that are outliers can be used in the regression analysis to develop an emissions model. Therefore, outliers are excluded from the effective range of an independent variable.

9 Meaning of normal value for a site constant

(1) A site constant for an implementation is at its normal value in a measurement time interval if:

(a) for a baseline emissions model—the value of the site constant in the measurement time interval is the same as the value in the baseline measurement period; or

(b) for an operating emissions model—the value of the site constant in the measurement time interval is the same as the value in the operating measurement period for the model.

(2) For subsection (1), the value of the site constant in the measurement time interval is taken to be the same as in the baseline measurement period if the only variations in the value of the site constant in the measurement time interval are those that have no observable effect on the consumption of baseline relevant energy for the implementation in the measurement time interval.

(3) For subsection (1), the value of the site constant in the measurement time interval is taken to be the same as in the operating measurement period if the only variations in the value of the site constant in the measurement time interval are those that have no observable effect on the consumption of operating relevant energy for the implementation in the measurement time interval.

10 References to factors and parameters from external sources

(1) If 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.

(b) interactive equipment for the implementation; or

(c) co‑metered equipment for the implementation.

Division 3—Making choices for the project

15 Sub‑methods

(1) For each implementation that is included in the project, the project proponent must choose one sub‑method to work out the emissions abated by the implementation.

(2) If a project proponent uses a sub‑method to work out the emissions abated by the implementation for the first reporting period and then uses an alternative sub‑method to work out the emissions abated by the implementation for a later reporting period, the alternative sub‑method must be used for all subsequent reporting periods.

16 Baseline relevant energy

For each implementation, the project proponent must identify the baseline relevant energy for the implementation for the purposes of developing the baseline emissions model for the implementation.

17 Baseline measurement period

(1) For each implementation, the project proponent must choose a measurement period (a baseline measurement period) for the purposes of developing the baseline emissions model for the implementation.

(2) The baseline measurement period chosen must be a period that:

(a) accounts for the typical range of operating conditions for the equipment covered by the baseline relevant energy for the implementation; and

(b) reasonably represents operating conditions for the equipment where, having undertaken the implementation, it is likely that the fuel or electricity consumption by the equipment would increase.

Note: For example, if the equipment produces different levels of emissions in different seasons, the baseline measurement period chosen must cover all relevant seasons.

(3) The project proponent must choose a start date and time and an end date and time for the baseline measurement period.

(4) The start date for the baseline measurement period must be no earlier than 24 months before the date the implementation commences.

(5) The end date for the baseline measurement period must be before the date the implementation commences.

18 Operating relevant energy

(1) For each implementation covered by sub‑method 1, the project proponent must identify the operating relevant energy for the implementation for the purposes of working out the total measured emissions for the crediting period.

(2) For each implementation covered by sub‑method 2, the project proponent must identify the operating relevant energy for the implementation for the purposes of developing an operating emissions model for the implementation.

19 Operating measurement period

(1) For each implementation covered by sub‑method 2, the project proponent must choose a measurement period (an operating measurement period) for the purposes of developing an operating emissions model for the implementation.

(2) The operating measurement period chosen must be a period that:

(a) accounts for the typical range of operating conditions for the equipment covered by the operating relevant energy for the implementation; and

(b) reasonably represents operating conditions for the equipment where, having undertaken the implementation, it is likely that the fuel or electricity consumption by the equipment would increase.

Note: For example, if the equipment produces different levels of emissions in different seasons, the operating measurement period chosen must cover all relevant seasons.

(3) The project proponent must choose a start date and time and an end date and time for the operating measurement period.

(4) The start date for the operating measurement period must be a day after the implementation has been completed.

20 Measurement time intervals

(1) For each implementation, the project proponent must choose the length of the measurement time interval for the purposes of working out emissions abated for the implementation.

(2) The start of the first measurement time interval in a time period is the start of the time period. The start of the second or subsequent measurement time interval is immediately after the end of the previous measurement time interval.

(3) In using a sub‑method to work out the emissions abated by an implementation, the same measurement time interval must be used for every parameter for the purposes of working out the emissions abated by the implementation. This measurement time interval must be used throughout the baseline measurement period, each operating measurement period and each reporting period for the implementation.

Note 1: This means that all the measurement time intervals in a period for every parameter in that period will coincide.

Note 2: However, only eligible measurement time intervals are taken into account when working out the emissions abated by an implementation.

21 Interactive effects

(1) The project proponent must identify the interactive effects for each implementation.

(2) If a change in emissions is an interactive effect for the baseline measurement period, the change is to be treated as an interactive effect for each:

(a) operating measurement period for the implementation; and

(b) reporting period for the implementation.

Note: For the purposes of calculating emissions abated by the implementation under Part 4, a change in emissions may be accounted for in baseline relevant energy or identified as an interactive effect. The project proponent may choose not to identify the change as an interactive effect because the sub‑methods in the Part include a threshold for the value of interactive effects.

(3) For each interactive effect, the project proponent must choose an approach for estimating the interactive effect that:

(a) uses data from the records of the site of the implementation; and

(b) is consistent with an estimation approach that applies to the change in emissions from consumption of fuel or electricity under another methodology determination or, if there is no methodology determination that deals with that change, is consistent with one of the following approaches:

(i) an estimation approach that applies to changes of that kind under another emissions reduction scheme that has been approved by a government (including a foreign government);

(ii) a generally accepted energy efficiency measurement and verification practice that applies to changes of that kind;

(iii) a generally accepted engineering methodology, model or formula that applies to changes of that kind; and

(c) is consistent with relevant measuring and estimation requirements that apply to the consumption of fuel or electricity under the NGER (Measurement) Determination; and

(d) results in an estimate that is measurable, capable of being verified and conservative; and

(e) is credible and robust.

Note 1: An approach applying to a change in consumption for the purposes of paragraph (3)(b) may involve the calculation of emissions from consumption of energy, the direct calculation of a change in emissions, or a combination of both.

Note 2: If the change in emissions that is an interactive effect is a reduction in emissions, the value of the interactive effect will be negative.

(4) However, in estimating the interactive effect using an approach chosen in accordance with subsection (3), the project proponent must:

(a) work out emissions factors for each greenhouse gas j released due to the consumption of fuel type i using the approach that applies for working out EFi,j in section 46; and

(b) work out the energy content factor of fuel type i using the approach that applies for working out ECi in section 46; and

(c) work out emissions factors for the consumption of electricity using the approach that applies for EFElec in section 46.

22 Independent variables

(1) The project proponent must choose one or more independent variables for the purposes of developing the baseline emissions model for an implementation.

(2) The project proponent must choose one or more independent variables for the purposes of developing an operating emissions model for an implementation covered by sub‑method 2.

(3) At a minimum, the project proponent must choose the following independent variables (subject to subsection (4)):

(a) the service levels provided by equipment at the site of the implementation;

(b) the quality of inputs to equipment at the site of the implementation;

(c) the types of inputs to equipment at the site of the implementation;

(d) the quality of outputs from equipment at the site of the implementation;

(e) the types of outputs from equipment at the site of the implementation.

Note: A variable of a kind referred to in paragraphs (a) to (e) is only an independent variable if, among other things, it is independent from any other independent variable for the model (see the definition of independent variable in section 5).

(4) Subsection (3) does not apply if:

(a) a variable would have no observable effect on the consumption of baseline relevant energy (for a baseline emissions model) or operating relevant energy (for an operating emissions model); or

(b) the project proponent has identified the variable as a site constant.

23 Site constants

(1) For each implementation, the project proponent must identify the parameters that are site constants for the purposes of working out the emissions abated by an implementation.

(2) If a parameter is a site constant for the implementation for the baseline measurement period, the parameter is to be treated as a site constant for each:

(a) operating measurement period for the implementation; and

(b) reporting period for the implementation.

(3) If a parameter is a site constant for the implementation for an operating measurement period, the parameter is to be treated as a site constant for:

(a) each reporting period relevant to the operating measurement period; and

(b) any subsequent operating measurement period for the implementation.

Division 4—Developing emissions models

24 Emissions models

(1) The project proponent must develop a baseline emissions model in the form of equation 28 for each implementation.

Note: The regression analysis used to develop the model may have to be revised from one reporting period to another, as necessary: see section 26.

(2) The project proponent must develop an operating emissions model in the form of equation 29 for each implementation covered by sub‑method 2.

Note: The regression analysis used to develop the model may have to be revised from one reporting period to another, as necessary: see section 26.

(3) The project proponent may develop a new operating emissions model for an implementation for the purposes of any subsequent reporting period.

(4) In developing the new operating emissions model the project proponent:

(a) must choose a new operating measurement period in accordance with section 19; and

(b) may choose different independent variables in accordance with section 22.

25 General requirements

(1) An emissions model for an implementation must be developed using regression analysis to relate independent variables to the dependent variable for the implementation.

(2) The values of the independent variables and dependent variable used in the regression analysis to develop the model must be values from measurement time intervals for the model in which:

(a) site constants for the implementation are at their normal values; and

(b) no values of the independent variables are outliers (as identified using standard statistical tests and approaches).

(3) The statistical tests and approaches used to identify outliers for the purpose of developing an emissions model for an implementation must be used to identify outliers for each emissions model subsequently developed for the implementation.

(4) The modelled relationship between the dependent variable and the independent variables for the model must not be disproportionately affected by a small number of high leverage data points (worked out using standard statistical tests and approaches).

(5) The statistical tests and approaches used for the purposes of subsection (4) for the purposes of developing an emissions model for an implementation must be used for the purposes of subsection (4) for each emissions model subsequently developed for the implementation.

(6) The value of the dependent variable for a measurement time interval used in the regression analysis to develop the model is the value of total measured emissions for the implementation worked out under section 46.

26 Using NGER methods to work out factors

(1) This section applies to working out the following parameters for the purposes of calculating the emissions abated by an implementation for a reporting period:

(a) the energy content factor of fuel type i;

(b) the emissions factor for greenhouse gas type j released due to the combustion of fuel type i.

Same NGER method to be used for baseline and measured or operating emissions

(2) If a project proponent works out a parameter in accordance with an NGER method, the project proponent must use the method to work out the parameter for the purposes of:

(a) the baseline emissions model for the implementation (to work out total measured emissions from the consumption of baseline relevant energy which is used in the regression analysis); and

(b) whichever of the following is applicable:

(i) for sub‑method 1—working out total measured emissions from the consumption of operating relevant energy;

(ii) for sub‑method 2—the operating emissions model for the implementation for the reporting period (to work out total measured emissions from the consumption of operating relevant energy which is used in the regression analysis).

Note 1: The project proponent may choose to use an NGER method in accordance with the monitoring requirements or be required to use one as a consequence of failing to monitor a parameter as required (see Division 3 of Part 5).

Note 2: This means that the regression analysis used in an emissions model may need to be revised if a different method is used or if the method has been amended.

Current version of NGER method to be used if possible

(3) If it is not possible to use the version of the NGER method as in force at the end of the reporting period for the purposes of paragraph (2)(a) or (b), the project proponent must use the most recent version of the NGER method that it is possible to use for the purposes of that paragraph.

(4) To avoid doubt, subsection (3) has effect despite paragraph 10(2)(b).

Emissions‑weighted average of factor to be used for emissions models

(5) If, in using a version of an NGER method for the purposes of an emissions model in accordance with this section, more than one factor would apply in the baseline measurement period or an operating measurement period, the factor to be used for the period is the emissions‑weighted average of all the factors that would have applied during the period.

27 Minimum statistical requirements

An emissions model for an implementation must, at a minimum, meet the following statistical requirements:

(a) each independent variable coefficient must have a t‑statistic that is greater than the value for the 2‑tailed t‑distribution at the 95% confidence level for the number of degrees of freedom in the regression (equivalent to 97.5% confidence in a 1‑tailed distribution);

(b) the adjusted coefficient of determination (adjusted R2) must be greater than 0.75;

(c) variation in each independent variable must affect the dependent variable in a way that can be explained by reference to an effect on the consumption of:

(i) for the baseline emissions model—baseline relevant energy; or

(ii) for an operating emissions model for the implementation—operating relevant energy for the model;

(d) the residuals of the emissions model must be (confirmed using standard statistical tests and approaches):

(i) homoscedastic; and

(ii) normally distributed; and

(iii) free of auto‑correlation;

(e) the relative precision of the emissions level predicted by the emissions model for the baseline measurement period or the operating measurement period for the model (as the case may be) calculated at the 95% confidence level must be within 100%.

Note: The number of degrees of freedom means the number of data points (measurement time intervals) in the regression minus the number of independent variables in the regression minus 1.

30 When an implementation may be included in calculating the net abatement amount

(1) For the purposes of working out the carbon dioxide equivalent net abatement amount for a reporting period, the project proponent may calculate abatement for an implementation for the reporting period if the implementation has been completed.

(2) However, if:

(a) the project proponent calculates abatement for an implementation for a reporting period; and

(b) the project proponent chooses not to calculate abatement for the implementation in a subsequent reporting period (the later period); and

(c) it would have been practicable for the project proponent to calculate abatement for the implementation in the later period;

the project proponent must not calculate abatement for the implementation for any reporting period subsequent to the later period.

31 When an implementation must not be included in calculating the net abatement amount

For the purposes of working out the carbon dioxide equivalent net abatement amount for a reporting period, the project proponent must not calculate abatement for an implementation for the reporting period if:

(a) the project proponent has undertaken an activity at the site of an implementation (whether the activity is of a kind referred to in subsection 11(2) or otherwise); and

(b) the activity was not described under paragraph 13(1)(a) or (b) as part of any implementation, or likely implementation, in the application under section 22 of the Act in relation to the project; and

(c) the activity could reasonably be expected to have an effect, that is not minor or trivial, on the emissions abated by the implementation that would be calculated for the implementation for the reporting period.

32 Certain consumption that may be excluded in calculating the emissions abated by an implementation

For the purposes of working out the emissions abated by an implementation for a reporting period, the project proponent may choose not to account for one or more changes in fuel or electricity consumption that occur as a result of the implementation being undertaken if:

(a) it is impractical or disproportionally costly to account for those changes in fuel or electricity consumption (including accounting for those changes as interactive effects); and

(b) not accounting for the total of those changes in fuel or electricity consumption would be reasonably likely to result in a difference of 5% or less in the emissions abated by the implementation for the reporting period; and

(c) the fuel or electricity consumption is excluded from both baseline relevant energy and operating relevant energy.

33 Negative final carbon dioxide equivalent net abatement amount taken to be zero

If the carbon dioxide equivalent net abatement amount for the final reporting period in the crediting period is a negative amount the carbon dioxide equivalent net abatement amount for the reporting period is taken to be zero.

Division 3—Implementation using measured emissions—sub‑method 1

35 Summary

Sub‑method 1 works out the emissions abated by an implementation for a reporting period by comparing modelled baseline emissions with measured operating emissions in the reporting period.

If there has been a decrease in emissions (i.e. the difference between baseline emissions and operating emissions is positive), the emissions abated by the implementation is worked out by comparing modelled baseline emissions (taking into account an improvement factor) with measured operating emissions, taking into account an accuracy factor.

However, if there has been a decrease in emissions and emissions from interactive effects are greater than the interactive effects threshold, the emissions abated by the implementation is taken to be zero.

If there has been an increase in emissions (i.e. the difference between baseline emissions and operating emissions is negative), the emissions abated by the implementation is the negative amount (worked out by comparing modelled baseline emissions with measured operating emissions) plus any emissions from interactive effects.

However, if there has been an increase in emissions and emissions from interactive effects are greater than the interactive effects threshold, the emissions abated is worked out without accounting for any emissions from interactive effects.

The project proponent must use the estimate of the parameter where:

(a) if the failure relates to baseline relevant energy—the factor for fuel type i and greenhouse gas j in Schedule 1 to the NGER (Measurement) Determination; and

(b) if the failure relates to operating relevant energy—

(i) for any cumulative period of up to 3 months in any 12 months of a crediting period for the project—the factor for fuel type i and greenhouse gas j in Schedule 1 to the NGER (Measurement) Determination multiplied by 1.1; and

(ii) for any cumulative period of up to 3 months in excess of that 3 months—the factor for fuel type i and greenhouse gas j in Schedule 1 to the NGER (Measurement) Determination multiplied by 1.5

(2) 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.
