The latest quarterly update of Australia's National Greenhouse Gas Inventory: December 2024 is now available.
The report shows emissions were 446.4 million tonnes of carbon dioxide equivalent (Mt CO2-e) in the year to December 2024. This is essentially flat compared with the previous year, with national emissions estimated to have increased 0.05% (0.2 Mt CO2-e). At the sector level, year-on-year changes include:
- Decreased emissions from industrial processes and product use (down 5.0%; 1.6 Mt CO2-e), due primarily to technology and production changes in the chemicals and metals sectors.
- Decreased emissions from agriculture (down 2.0%; 1.6 Mt CO2-e), mainly due to decreased crop production.
- Decreased emissions in stationary energy (excluding electricity) (down 1.0%; 1.0 Mt CO2-e), reflecting decreased combustion activity.
- Increased electricity emissions (up 2.2%; 1.5 Mt CO2-e), as lower hydro generation led to increased contribution from all other forms of generation, including fossil fuels.
- An increase in transport emissions (up 1.9%; 1.9 Mt CO2-e), mainly due to consumption of road diesel and domestic aviation fuel reaching their highest levels on record.
Emissions in the year to December 2024 were 27.0% below June 2005 levels (the base year for Australia's 43% reduction by 2030 target under the Paris Agreement).
The Quarterly Update incorporates data from Australia's latest official National Inventory Report submitted to the United Nations Climate Change Secretariat. The National Inventory Report 2023 fulfils Australia's greenhouse gas reporting requirements under the United Nations Framework Convention on Climate Change and the Paris Agreement.
