The information required by clause 3 of this notice must be provided to the Ministry within 30 working days of the date of this notice.

Schedule 1

Emissions Rules

1. Data must be supplied for each financial year from only the following emissions sources, expressed in tonnes of CO₂ equivalent:

1. the direct use (eg, oxidation or use as feedstock) of any coal, natural gas, used oil, or waste oil as part of the activity; and
2. the direct use (eg, example oxidation or use as feedstock) of any coal, natural gas, used oil, or waste oil to generate steam that is used as part of the activity; and
3. the direct use of geothermal fluid as part of the activity, including the direct use of geothermal fluid to generate steam that is used as part of the activity; and
4. any of the activities listed in Part 4 of Schedule 3 of the Act carried out as part of the activity; and
5. the direct use of any liquid fossil fuel in stationary equipment; and
6. fugitive coal seam gas from coal that is used as part of, or to generate steam that is used as part of, the activity; and
7. the electricity used as part of the activity; and
8. the combustion of used tyres for the purpose of generating industrial heat; and
9. the consumption of carbon dioxide as a feedstock if that carbon dioxide is derived from an activity in Schedule 3 or 4 of the Act and a participant is required to surrender units under this Act for that activity.

2. Emissions must be calculated using the applicable formulae and emission factors specified in these data collection rules and in the Data Form. Direct measures cannot be used as a substitute.

The formulae and emission factors used in calculating emissions, except for the use of CO₂ as a feedstock, must be those listed in Schedule 2 of the Climate Change (Stationary Energy and Industrial Processes) Regulations 2009, Schedule of the Climate Change (Liquid Fossil Fuels) Regulations 2008, the data collection rules, and the relevant Data Form.

The following formulae should be used to measure direct emissions and fugitive emissions of eligible activities.

Coal

Emissions = Σ(A_i × CV_i × EF_i)
where:
A_i = tonnes of coal consumed for the relevant coal class
CV_i = calorific value of the relevant coal class
EF_i = emission factor for the relevant coal class
i = index for the relevant coal class.

Fugitive coal seam gas

Emissions = Σ(A_i × EF_i)
where:
A_i = tonnes of coal (of domestic origin) consumed for the relevant coal class from the relevant mine type
EF_i = emission factor for the relevant mine type
i = index for each relevant mine type.

Natural gas

Emissions = Σ(A_i × EF_i)
where:
A_i = terajoules (tonnes if LPG) of natural gas consumed from the relevant natural gas source or field
EF_i = emission factor for the relevant natural gas source or field, (use the national average if the gas field(s) is not known)
i = index for each relevant natural gas source or field.

Geothermal fluid

Emissions = Σ(A_i × EF_i)
where:
A_i = tonnes of geothermal fluid for the relevant type (ie, steam or 2 phase) consumed from the relevant source
EF_i = emission factor for the relevant geothermal fluid source
i = index for each relevant geothermal fluid source.

Used or waste oil and used tyres

Emissions = Σ(A × CV × EF)
where:
A = tonnes of used or waste oil, or used tyres consumed
CV = calorific value of used, or waste oil, or used tyres
EF = emission factor for used, or waste oil, or used tyres.

Liquid fossil fuels

Emissions = Σ(A_i × EF_i)
where:
A_i = kilolitres of liquid fossil fuel consumed from the relevant source
EF_i = emission factor for the relevant liquid fossil fuel source
i = index for each relevant liquid fossil fuel source.

CO₂ as a feedstock

Emissions = A × EF
A = tonnes of CO₂ used as a feedstock
EF = emission factor for CO₂ (1 tCO₂e/ tCO₂).

3. Emissions from the direct oxidation or use as feedstock of coal or natural gas must be calculated as zero when either:

(1) the feedstock is used to produce an obligation fuel defined in the Climate Change (Liquid Fossil Fuels) Regulations 2008, or

(2) the production of the output is eligible to earn emission units under the Climate Change (Other Removal Activities) Regulations 2009.

4. Emissions for which no obligation to be a participant of the NZ ETS exists under the Act due to an exemption made by Order in Council under section 60 of the Act must be included; however, upon submission, the applicable threshold will be applied and any emissions sources below the threshold will be withheld from the relevant calculation of the industrial allocative baseline.

5. Total emissions from a combined heat and power plant must be allocated to an activity in proportion to its use of the output of the plant. Total emissions from co-generation must be split between heat/steam and electricity emissions on the basis of relative efficiencies of production, using efficiency rates of 80% for steam and 35% for electricity, then the heat/steam emissions must be allocated to the activity in proportion to its use of the output of heat from the plant.

Emissions allocated to heat/steam production must be estimated using the following formula:

Where:

E_H = emissions allocated to steam production
H = steam output (MWh)
e_H = assumed efficiency of steam production
P = delivered electricity generation (MWh)
e_p = assumed efficiency of electricity generation
E_T = total direct emissions of the combined heat and power plant system
E_p = emissions allocated to electricity production.

6. Emissions from industrial processes must be calculated using the formulae set out in Part 3 of the Climate Change (Stationary Energy and Industrial Processes) Regulations 2009.

7. Indirect emissions from electricity use must be calculated using the following formula:

Emissions = A × EAF
Where:
A = consumption of electricity (MWh) used as part of the activity
EAF = relevant electricity allocation factor.

8. For eligibility purposes, electricity emissions must be estimated using an electricity allocation factor of 1 tonne of CO₂-e per megawatt hour of consumption.

9. For allocative baseline purposes, electricity emissions must be estimated using an electricity allocation factor of 0.554 tonnes of CO₂-e per megawatt hour of consumption.

10. Best endeavours must be used in calculating emissions.

Simplified and reasonable emission calculation methods of the person’s own design can be used for specified small emissions sources that are either excluded or included emissions defined in Schedules 2 and 3 of the relevant New Zealand Gazette Notice. These estimations of emissions data must be, in aggregate, estimated to be no more than 5% of total emissions from the activity at the site, provided that a 5% change in total estimated emissions would not change the eligibility status of the activity, if the activity of the person was considered in isolation when making a decision about eligibility. All methods used must be disclosed in the Basis of Preparation.

11. All emissions associated with the activity must be counted, regardless of whether the output is of saleable quality.

Data Preparation Rules

1. The methods, assumptions and calculations used to produce the data must be disclosed in the Basis of Preparation along with the data in the Data Form.

2. Where uncertainties arise when determining emission and revenue data, these uncertainties must be declared in the Basis of Preparation.

Schedule 2
