2023 NGER Act Review

The Climate Change Authority has released its second review of the National Greenhouse and Energy Reporting (NGER) legislation.  

The authority is required to review the operation of the National Greenhouse and Energy Reporting Act 2007 (NGER Act) every five years. The authority’s review of the NGER legislation is required to be delivered to the Minister for Climate Change and Energy by 31 December 2023, as is the authority’s 2023 review of the Carbon Credits (Carbon Farming Initiative) Act 2011 (ACCU Scheme Review) which is reviewed every three years. 

The NGER legislation establishes: 

  • the National Greenhouse and Energy Reporting scheme  

  • the Safeguard Mechanism 

  • a framework for the administration and compliance for these schemes.  

The authority’s 2023 review of the NGER legislation primarily focused on the NGER scheme. The reformed Safeguard Mechanism only recently commenced operation and sufficient data are not yet available to assess its performance.  

The NGER scheme is performing well but the time is right to make some changes to ensure it remains fit-for-purpose.  

The momentum of the global net zero transition is changing the domestic and international data needs for many countries. Australia’s NGER scheme is well-established and reputable but it is important to how the scheme may need to evolve in response to these changes—whether that be to meet new expectations from the public, improve or enhance the interactions of the NGER scheme with new reporting initiatives, or ensure it remains best practice.   

The authority recognises these changing needs. The authority’s 2023 review puts forward 25 recommendations for the government to consider, relating to the following key themes of the NGER scheme:  

  • NGER scheme coverage including reporting thresholds and sectoral coverage 

  • Transparency and confidentiality  

  • Estimation methods, with a focus on fugitive methane measurement, reporting and verification 

  • Administration and compliance of the NGER scheme.
