Note: Emission estimates for some subsectors are not available for states and territories due to confidentiality constraints. The difference between the national and the sum of the state and territory emissions (less than 0.2%) reflects including military transport and external territories in the national inventory.

Data insights
New South Wales:
- Total emissions for New South Wales in 2019 were 136.6 Mt CO2-e.
- Emissions have declined 17.2% on 2005 levels, mainly due to reductions in emissions from stationary energy (mostly electricity) and the land sector
- Emissions from transport have increased.
Victoria:
- Total emissions for Victoria in 2019 were 91.3 Mt CO2-e.
- Emissions have declined 24.8% from 2005 levels, mainly due to reductions in emissions from stationary energy (mostly electricity) and the land sector.
- Emissions from transport have increased.
Queensland:
- Total emissions for Queensland in 2019 were 164.5 Mt CO2-e.
- Emissions have decreased by 13.7% on 2005 levels, with large reductions from the land sector. This is principally driven by lower rates of primary forest clearing.
- Emissions have increased in the stationary energy and fugitive from fossil fuel extraction sectors. This is principally due to strong mining and export growth.
- Transport emissions have risen, reflecting long term growth in population and vehicle fleets.
Western Australia:
- Total emissions for Western Australia in 2019 were 91.9 Mt CO2-e.
- Emissions have increased 20.8% on 2005 levels.
- Strong growth in mining and exports has driven increases in stationary energy and fugitive emissions from fossil fuel extraction.
- Long term growth in population and vehicle fleets has resulted in increased transport emissions.
South Australia:
- Total emissions for South Australia in 2019 were 23.9 Mt CO2-e.
- Emissions have decreased by 32.9% on 2005 levels, mainly due to reductions in emissions from stationary energy (electricity) and the land sector.
Tasmania:
- Total emissions for Tasmania in 2019 were -1.7 Mt CO2-e.
- Net emissions have declined by 108.7% on 2005 levels, due to lower emissions from the land sector. This has mainly been from reductions in native forest harvesting.
Australian Capital Territory:
- Emissions in the Australian Capital Territory for 2019 were 1.3 Mt CO2-e, an 8.1% decrease on 2005.
- The largest upward pressure on emissions was from the transport sector.
Northern Territory:
- Total emissions for the Northern Territory in 2019 were 20.7 Mt CO2-e.
- Emissions have increased by 46.5% on 2005 levels.
- Strong growth in mining and exports has driven increases in fugitive emissions from fossil fuel extraction and stationary energy emissions.
About the data
The State and Territory Greenhouse Gas Inventories 2019 provide an overview of the latest available estimates of greenhouse gas emissions for Australia’s states and territories. Estimates are calculated on a United Nations Framework Convention on Climate Change (UNFCCC) accounting basis.
These state and territory emission estimates are based on national estimates in the National Inventory Report 2019, submitted to the UNFCCC. They are consistent with how the Australian Government will acquit its emission reduction commitments under the Paris Agreement.
