National Greenhouse Gas Inventory 29 May

Dept of Climate Change, Energy, Environment & Water

The report shows emissions were 458.9 million tonnes of carbon dioxide equivalent (Mt CO2-e) in the year to December 2025, a decrease of 2.1% (9.7 Mt CO2-e) compared with the previous year. At the sector level, year-on-year changes include:

  • Decreased electricity emissions (down 3.8%; 5.7 Mt CO2-e), reflecting record renewables generation and the ongoing displacement of coal and gas;
  • Decreased fugitive emissions (down 5.2%; 2.5 Mt CO2-e), mainly due to reductions in natural gas venting emissions and new carbon capture and storage activities, as well as a decline in production from underground coal mining;
  • Decreased emissions in stationary energy (excluding electricity) (down 1.6%; 1.5 Mt CO2-e), reflecting decreased combustion activity including for oil and gas extraction;
  • Decreased emissions from agriculture (down 0.1%; 0.1 Mt CO2-e), mainly due to the balance of lower grazing cattle and sheep numbers offset by increased emissions from cropping;
  • Decreased emissions from transport (down 0.6%; 0.6 Mt CO2-e), mainly driven by a decrease in petrol consumption for road transport, partially offset by increased domestic aviation activity and road transport diesel consumption; and
  • Increased emissions from industrial processes and product use (up 3.0%; 0.9 Mt CO2-e), primarily due to increased production of steel.

Emissions in the year to December 2025 were 24.5% below September 2005 levels (the base year for Australia’s 43% reduction by 2030 target under the Paris Agreement).
