Important information for responsible emitters

The National Greenhouse and Energy Reporting (Safeguard Mechanism) Rule 2015 has been amended to extend the 2018–19 baseline application deadline from 31 October 2019 to 15 April 2020 for facilities with a declared multi-year period, that covers the 2018–19 and 2019–20 compliance years. It also allows facilities to use the transitional calculated baseline criteria a second time from the 2019–20 year onwards, to adopt newly established government-determined prescribed production variables. Further information can be found in the explanatory statement for this latest amendment.

This website includes references to prescribed (annually adjusted) and prescribed (fixed) production variables that are yet to be finalised by the Department of the Environment and Energy.

Applications will not be able to use prescribed production variables or default emissions intensities until they have been included in Schedules 2 and 3 of the Safeguard Rule.

For more information please contact the Clean Energy Regulator.

​Emissions baselines represent the reference point against which emissions performance will be measured under the safeguard mechanism. A safeguard facility must keep its net emissions levels at or below its baseline.

There are four main types of emissions baselines:

  • Reported baseline—determined based on the historical high point of emissions reported under the National Greenhouse and Energy Reporting scheme between 2009–10 and 2013–14. Reported baselines will cease on 1 July 2020. Facilities will need to apply for a different type of baseline.
  • Calculated baseline—determined based on an independently audited forecast of production and either forecast emissions intensity provided by the responsible emitter or the default emissions intensity value.
  • Production-adjusted baseline​determined based on actual production levels. A production adjusted baseline can either be a fixed baseline based on actual production during the calculated or benchmark baseline period, or annually adjusting based on actual production in that year.
  • Benchmark baseline—based on benchmark emissions intensities (that is, the best, least emissions intensive standard for production) and an independently audited forecast of production. A landfill-benchmark baseline will be based on a benchmark capture efficiency rate for non-legacy emissions.

Both calculated baselines and benchmark baselines are determined using forecasts of production, and can be replaced with a production-adjusted baseline that reflects actual production from the facility.

A facility must exceed the 100,000t CO2-e threshold to be covered by the safeguard mechanism. A baseline cannot be set below this level.​

In some circumstances a facility covered by the safeguard mechanism may apply for a baseline variation.
