Landfill gas method variation

Closed 20 Nov 2020

Opened 26 Oct 2020

Results updated 21 May 2021

The Carbon Credits (Carbon Farming Initiative—Landfill Gas) Methodology Determination Variation 2021 came into effect on 7 May 2021.

The variation implements findings from the Emissions Reduction Assurance Committee’s reviews of the method. This included a crediting period extension review under section 255A of the Carbon Credits (Carbon Farming Initiative) Act 2011.

This variation:

  • extends the crediting period for landfill gas flaring activities by 5 years (new flaring projects receive a 12-year crediting period)
  • clarifies the eligibility requirements for upgrade projects
  • changes the default methane proportion for landfill gas from 50% to 42% for new projects

Read the landfill gas variation and the explanatory statement

The Committee provided advice to the Minister about the variation in accordance with subsection 114(8) of the Carbon Credits (Carbon Farming Initiative) Act 2011.



The Emissions Reduction Assurance Committee has completed a periodic review of the Landfill Gas method. The periodic review examined whether the method continues to comply with six offsets integrity standards. These are set out in section 133(1) of the Carbon Credits (Carbon Farming Initiative) Act 2011. An earlier crediting period extension review considered whether crediting periods of projects registered under the method should be extended under section 255A of the Act.

The Committee is calling for submissions on a draft variation to the method developed to implement their findings in the two reviews.

As stakeholders were previously consulted on some of these issues, the Committee has approved a shorter consultation period of 21 days.

Responsibilities for the Emissions Reduction Fund method development have transferred to the Clean Energy Regulator. Our department will provide submissions to the Regulator.

Next Steps

The Regulator will undertake further consultation in 2021 around:

  • ongoing audit requirements for ERF projects with an extended crediting period
  • a new landfill gas method providing an extended crediting period for projects engaged in electricity generation
