The source category, source, activity types, and fuel types available are based on the National Greenhouse and Energy Reporting Regulations 2008 (NGER Regulations) and National Greenhouse and Energy Reporting (Measurement) Determination 2008 (Measurement Determination).

Selecting from these types will determine what additional information is required.

You must calculate the emissions for each gas available (if any) before being able to click 'Save'.

Please find below further explanatory details regarding some of the information collected.

1. Incidental reporting

Under regulation 4.27 of the NGER Regulations, incidental reporting can be used in relation to facilities with sources that result in an amount of emissions or energy consumption or energy production below the specified thresholds, where that information is not required to be collected or provided under any other Commonwealth, state, or territory law.

2. Measurement criterion

Measurement criteria are rules by which the base quantities for determining the amount of greenhouse gas emissions and energy consumption are to be estimated for the purposes of the NGER Act. Specifically, these rules may set out how the following are to be estimated:

  • the amount of fuel consumed or combusted for a source
  • the amount of fuel related to fugitive emissions from the extraction, production, processing and distribution of fossil fuels
  • the amount of carbonates consumed, synthetic gas emitted, and fuel used as a feedstock or as carbon reductant related to industrial process emissions, and
  • the amount of waste for a source

There are four different measurement criteria that can broadly be defined as follows:

  1. Criterion A - quantity verified by invoices
  2. Criterion AA - quantity verified by stockpile change estimation and invoices
  3. Criterion AAA - quantity measured at point of sale or point of consumption/production using measuring equipment calibrated to a measurement requirement as specified in the Measurement Determination
  4. Criterion BBB - quantity measured or estimated in accordance with industry practice

Measurement criterion AAA can be further delineated into three sub-criteria:

  1. AAA - commercial transaction - point of consumption - quantity acquisition involves a commercial transaction and is measured at the point of consumption (or, in the case of carbonates, measured at the point of production of products derived from carbonates)
  2. AAA - commercial transaction - point of sale - quantity acquisition involves a commercial transaction and is measured at the point of sale, but only if the change in stockpile is less than 1% of the total consumption for the year and, at the beginning of the year, the stockpile quantity is less than 5% of the total quantity consumed for the year
  3. AAA - NON-commercial transaction - point of consumption - quantity acquisition does not involve a commercial transaction and is measured at the point of consumption

Note that for carbonates, the term 'acquisition' can refer to the dispatch of products derived from carbonates, and the term 'point of consumption' can refer to the point of production of products derived from carbonates.

Further information on measurement criteria can be found on the Clean Energy Regulator's website.

3. Primary/secondary

As specified in the NGER Regulations, primary and secondary fuels are defined as follows:

  1. primary fuel or energy commodity means a fuel or energy commodity extracted or captured from natural sources with minimal processing, and includes the fuels and energy commodities mentioned in Schedule 1 (in the NGER Regulations) as being primary fuels or energy commodities.
  2. secondary fuel or energy commodity means a fuel or energy commodity produced by converting energy from one form (usually a primary fuel or energy commodity) to another form for consumption, and includes the fuels and energy commodities mentioned in Schedule 1 (in the NGER Regulations) as being secondary fuels or energy commodities.

This option is not available for all fuel/activity types displayed.

4. Energy content factor

These factors are used to calculate the energy consumption for an activity. The default energy content factors are specified in Schedule 1 of the Measurement Determination and are used to calculate energy consumption. If any other method is used then the user must provide an energy content factor where that method allows for it.

The energy content factor of a fuel or energy commodity is the gigajoules of energy per unit of the fuel or energy commodity measured as a gross calorific value.

5. Energy content (GJ)

This is the total quantity of energy consumed in gigajoules.

6. Scope 1 (t CO2-e)

As per regulation 2.23 of the NGER Regulations, scope 1 emissions of greenhouse gas, in relation to a facility, means the release of greenhouse gas into the atmosphere as a direct result of an activity or series of activities (including ancillary activities) that constitute the facility.

The scope 1 emissions displayed per tonnes of carbon dioxide equivalent are calculated based on the data entered into EERS.

7. Scope 2 (t CO2-e)

As per regulation 2.24 of the NGER Regulations, scope 2 emissions of greenhouse gas in relation to a facility means the release of greenhouse gas into the atmosphere as a direct result of one or more activities that generate electricity, heating, cooling or steam that is consumed by the facility but that do not form part of the facility.

The scope 2 emissions displayed per tonnes of carbon dioxide equivalent are calculated based on the data entered into EERS.

8. Emission factor

These factors are used to calculate the greenhouse gas emissions for an activity. The default emission factors are from Schedule 1 of the Measurement Determination and are used in most cases where Method 1 is selected for a gas. Enter a facility specific emissions factor if any other method is selected and a default is not provided.

9. Gas types

The gas types displayed are based on the source category, source and, activity combination selected. Please find below the list of possible gas types that may be displayed:

  • CO2 - Carbon dioxide
  • N2O - Nitrous oxide
  • CH4 - Methane
  • SF6 - Sulphur Hexafluoride
  • HFCs - Hydrofluorocarbons
  • CF4 - tetrafluoromethane
  • C2F6 - Hexafluoroethane

10. Method

The method for a source means a method specified for estimating emissions released from the operation of a facility in relation to that source. The methods available in the drop down list are based on the options provided in the Measurement Determination.

When entering data for a fuel combustion activity, a checkbox will appear to auto-calculate all the different greenhouse emissions via Method 1. Click on it and you will see the emission factor and result fields populate automatically as well as the total scope 1 emissions field ('Scope 1 (t CO2-e)'). Click on it again and the values will clear but only if higher order methods are available for the particular greenhouse gas and particular fuel combustion activity.

Note that after entering the emission factor for a greenhouse gas using a higher order method, the emissions will only auto-calculate when you move the cursor to a different field.

11. Emission factor

If a method other than Method 1 is selected, then an emission factor must be provided for EERS to calculate and display the associated emissions except for exceptional circumstances where a default is provided. The emission factor used for Method 1 is available in the Measurement Determination.

12. MTBIs

The source MTBIs (Matters to be Identified) are specified in the Measurement Determination. This information is mandatory, and may or may not have a bearing on the related calculation(s) to determine the emissions.

13. Waste mix type percentages

Reporters who report emissions generated from solid waste disposal on land must report the percentage of each waste mix type which is sourced from a particular waste stream in accordance with Schedule 3, Part 6, Item 1 (g) of the NGER Regulations.

There are four waste streams:

  • municipal waste,
  • commercial and industrial waste,
  • construction and demolition waste, and
  • shredder flock.

The percentages for each waste stream must add up to 100.
