EERS release 2020–21

03 August 2023

The Emissions and Energy Reporting System (EERS) is available for 2020–21 reporting. You can log in to EERS, enter data and submit your reports. If you experience any log in difficulties, please contact us on 1300 553 542.


What’s new in 2020–21

Changes made to the EERS for the 2020–21 reporting year include:

  • Updated emission factors based on updated Global Warming Potentials (GWPs) that convert non-carbon dioxide gases into carbon dioxide equivalent values.
  • Updated the list of matters to be identified in reports under Part 2 of Schedule 3 of the NGER Regulations (oil or gas).
  • Updated emission factors used to estimate emissions resulting from the consumption of electricity purchased or lost from the grid (scope 2 emissions).

Following the release of EERS on 1 July 2021, we will be also providing updates and adding important additional information to several guidance documents published on our website. These include:

  • Estimating emissions and energy in the electricity generation, transmission, and distribution sectors guideline.
  • Estimating emissions and energy from coal mining guideline.
  • Reporting hydrofluorocarbons and sulphur hexafluoride gases guideline.

Please watch out for these updated documents if they apply to you.

Identified issues in EERS for 2020–21 reporting

There are currently no identified issues in relation to the 2020–21 reporting period.

We will use this page to inform reporters of any issues identified in the EERS and provide advice on what actions reporters should take, including information on status of issue resolution.

We will update the identified issues on a regular basis, if required.

If the proposed 'Recommended reporter action/s' is unsuitable or does not resolve your issue, please contact us for more advice.

NGER legislation changes 

The Measurement Determination has been updated for 2020–21 onwards. Amendments include:

  • Updates to constants and emission factors for various methods, and emission factors in Parts 1 to 4 of Schedule 1, to reflect changes to global warming potentials described in regulation 2.02 of the Regulations.
  • Updated scope 2 emission factors as per the table below:
    2019–20 emission factor
    2020–21 emission factor
    0.81 (no change)
    0.81 (no change)
    WA (South West Interconnected System)0.69
    0.81 (no change)

  • New definitions, to clarify the matters to be identified (MTBI's) related to fugitive emissions from oil and gas, as described in Part 2 of Schedule 3 of the National Greenhouse and Energy Reporting Regulations 2008 (Regulations). These new MTBI's apply for the following sources:
    • Oil or gas exploration
    • Natural gas production or processing (other than venting or flaring)
    • Natural gas production or processing – venting.

More information on particular amendments is available in the National Greenhouse and Energy Reporting (Measurement) Amendment (2020 Update) Determination 2020.
