Multi-year monitoring period

Suggested Reading Suggested Reading

07 March 2019

​On 7​ March 2019, amendments to the National Greenhouse and Energy Reporting (Safeguard Mechanism) Rule 2015 came into effect. These amendments apply from the 2018-19 safeguard compliance period, onwards. Tools and resources available on the Clean Energy Regulator website will be updated shortly to reflect the amendments.

If you would like to discuss your individual circumstances under the safeguard mechanism, please contact the Clean Energy Regulator.

A multi-year monitoring period provides responsible emitters with time to implement emissions reduction projects, acquire Australian carbon credit units (ACCUs) or average out peaks and troughs in emissions.

About multi-year monitoring periods

Safeguard baselines are usually set based on emissions over a single financial year and this aligns with how emissions are reported under the National Greenhouse and Energy Reporting scheme. This allows responsible emitters to readily compare covered emissions reported for a facility in the financial year against the facility’s safeguard baseline and determine if a facility has exceeded its baseline. The single financial year is referred to as the ‘default monitoring period’.

If a facility has emissions that exceeded (or is reasonably likely to exceed) its safeguard baseline for a financial year (a default monitoring period), it may apply for a multi-year monitoring period. The monitoring period can be a two or three year period and provides responsible emitters with additional time to reduce the average net emissions from the facility to be below the baseline. Average net emissions can be reduced by either reducing actual emissions from the facility, or acquiring and surrendering ACCUs.


To be eligible for a multi-year monitoring period, a responsible emitter must be able to demonstrate that:

  • covered emissions in the first year of the multi-year monitoring period have been, or a reasonably likely to be, greater than the existing baseline for the facility, and
  • net emissions for the facility will be lower in the remaining years within the proposed multi-year monitoring period such that it will enable the facility to avoid an excess emissions position at the end of the monitoring period.

In addition to the above, a facility will also be ineligible for a multi-year monitoring period if the proposed monitoring period overlaps with an existing multi-year monitoring period, or the responsible emitter is also seeking, or has been granted a baseline variation for an improvement in emissions intensity in the first year of the proposed multi-year monitoring period

Please see the guidance within the documentasset::multi-year monitoring period application form for further information about what needs to be provided to demonstrate eligibility.

How to apply

To apply for multi-year monitoring period, please complete the multi-year monitoring period application form.

Applicants are encouraged to contact the Clean Energy Regulator on 1300 553 542 or via email, to discuss their application before submitting it for assessment.

Deadlines for submitting an application

Applications must be received by the Clean Energy Regulator no later than 31 October immediately following the first financial year of the proposed multi-year monitoring period.

If the responsible emitter provides reasons as to why it was impractical to meet the 31 October deadline, the Clean Energy Regulator may accept an application up until 1 February. If you are considering applying for a multi-year monitoring period after 31 October, you should contact the Clean Energy Regulator to discuss your application prior to 31 October.
