Australia's Q4 2023 Greenhouse Gas Emissions Update

Dept of Climate Change, Energy, Environment & Water

The latest Quarterly Update of Australia's National Greenhouse Gas Inventory: December 2023 is now available.

The report shows emissions were 432.9 million tonnes of carbon dioxide equivalent (Mt CO2-e) in the year to December 2023. This is a decrease of 0.5% (2.4 Mt CO2-e) compared with the previous year.

The change in emissions over the year to December 2023 reflects movements across sectors, including:

  • ongoing reductions in electricity emissions (down 2.8%; 4.4 Mt CO2-e) as renewable energy uptake continues to displace fossil fuel power sources
  • decreased fugitive emissions (down 2.1%; 1.0 Mt CO2-e), reflecting a fall in underground coal production and reductions in emissions from natural gas venting and flaring
  • decreased emissions in stationary energy (excluding electricity) (down 0.8%; 0.8 Mt CO2-e), reflecting decreased combustion activity
  • increased emissions from agriculture (up 0.7%; 0.5 Mt CO2-e), reflecting changes in crop production and livestock populations
  • increased transport emissions (up 3.6%; 3.4 Mt CO2-e), reflecting the continuing recovery from COVID-related movement restrictions.

Emissions in the year to December 2023 were 29.0% below June 2005 levels - (the base year for Australia's 43% reduction by 2030 target under the Paris Agreement).
