Considering adjusting your emissions baseline under the safeguard mechanism to cover increased emissions and avoid unnecessary offset costs? This article highlights key dates for applications and audit reports under the safeguard mechanism for facilities applying the calculated baseline approach to determine their baseline emissions number. For detailed information about the safeguard mechanism, including who is covered and how baseline emissions numbers are measured, see our recent blog:  Safeguard Mechanism - What you need to know




The safeguard mechanism begins 1 July 2016, and provides several approaches for measuring the emissions baseline number for large facilities (with emissions greater than 100,000 tonnes carbon dioxide equivalent), against which the facility's greenhouse gas emissions performance will be monitored.

Generally, if your facility has reported NGER scope 1 emissions greater than 100,000 tonnes carbon dioxide equivalent, the Clean Energy Regulator will issue a reported baseline emissions determination, based on historic NGER data, for that facility. If you are satisfied that this reported baseline determination is appropriate, you do not need to submit an application or audit report under the safeguard mechanism. However, there are a number of circumstances where historic emissions will be inappropriate, and you may prefer to apply a calculated emissions baseline approach to measure your facility’s baseline. Circumstances in which which calculated baselines are available include if your facility (i) is new, (ii) has undergone a significant expansion, (iii) has inherent emissions variability (applicable to natural resource sector), or (iv) is likely to exceed the reported (historic) baseline number in 2016/17 financial year (for further details, see Safeguard Mechanism - What you need to know).

If you require a calculated emissions baseline determination, you will need to submit an application and accompanying audit report to the Clean Energy Regulator.

Application and audit due dates for Calculated Emissions Baseline Determinations

The time at which you should submit your application and audit report for a calculated-emissions baseline determination depends on your circumstances. For calculated baselines that are to commence in the 2016-17 financial year, the ultimate deadline for applications, with accompanying audit reports, isn’t until 31 October 2017. (See Safeguard Rule subsection 22(3)). However, you may need to submit your application earlier, because the years that you can choose from to establish your baseline are limited by the timing of your application.

The general rule under the calculated baseline approach is that the year chosen to establish the baseline is in the future from when the application is made. This means that the quantity of emissions intensity must be estimated, rather than based on historic data. The rule aims to reduce the risk that emissions and emissions intensity are deliberately increased in a year in order to artificially increase the baseline.

The table below highlights which years can be considered in establishing the facility baseline emissions number for a determination beginning 1 July 2016, depending on the application timing.

Date Application Submitted

Baseline Year

Application (and accompanying audit) received by the Regulator before 31 July 2016

Financial year with the highest expected production of the primary production variable over the three year period to be covered by the determination (2016/17-2018/19) (or five years if it is a large new facility). [subparagraph 27(1)(c)(i)]

Application (and accompanying audit) received by the Regulator between 31 July 3016 - 30 July 2017

Financial year with the highest expected production of the primary production variable of the last two years to be covered by the determination (2017/18 – 2018/19) (or last four years if it is a large new facility). [subparagraph 27(1)(c)(ii)]

Application (and accompanying audit) received after 31 July 2017 and by deadline 31 October 2017.

The last financial year of the three year period to be covered by the determination (2018/19) (or last three years if it is a large new facility). [subparagraph 27(1)(c)(iii)]

Application timing for Initial Baseline Determinations

While timing of applications is a relevant consideration for all calculated baseline determinations, it will be particularly relevant for initial baseline determinations, which must commence in the first year of the safeguard mechanism, i.e. 1 July 2016. The initial baseline criteria allows for baselines to be adjusted if facilities expect to exceed their baseline in the safeguard mechanism’s first year. The baseline will be increased to reflect forecast emissions, using the calculated emissions baseline approach, similarly to the approach for new investments or significant expansion of a facility covered by the safeguard mechanism before 2020.

Applying the rules regarding application timing set out above, if your company expects to exceed its historic baseline in 2016/17, and otherwise meets the initial baseline emissions criteria, you may consider applying for an initial baseline determination, which will normally apply for a three year period from 1 July 2016 – 30 June 2019.

The following requirements must be met for an initial calculated baseline (noting that Grid connected electricity generators are not eligible to utilise the initial calculated baseline criteria):

  1. The facility must either have a reported-emissions baseline determination or have submitted emissions reports under the NGER Act for the five years starting on 1 July 2009.
  2. The facility has exceeded or expects to exceed its baseline emissions number in 2016‑17. Note that facilities must not deliberately increase or intend to increase their covered emissions for the purpose of meeting this criterion, e.g. by changing how emissions are reported or calculated or causing scope 1 emissions.

(For further details on these criterion, see the Safeguard Rule, section 26.)

When making your application, you will need to choose the appropriate year in the period covered by the calculated emissions baseline determination from which to set you baseline. Normally, this is the year with the highest (forecast) production level. However, the years from which you can chose are limited by the timing of your application, as noted above. So, If you want forecast emissions for 2016-17 to be included in the financial years from which your baseline can be established, you need to make your application before 31 July 2016 (see subparagraph 27(1)(c)(i) of the Safeguard Rule).

Similarly, if your intention is to use forecast production variable quantities for 2017-18 to calculate the baseline, you will need to submit the application with accompanying audit report before 31 July 2017 (see subparagraph 27(1)(c)(ii) of the Rule). It is important to be aware that baselines may be adjusted at the end of the 3 year calculated baseline determination where actual emissions are significantly different from forecast emissions.
