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.
About the data
The State and Territory Greenhouse Gas Inventories 2021 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 data comprise of national greenhouse gas emission estimates for the period 1989-90 to 2020-21 on an Australian financial year basis (i.e. the period July to June of each year, where 1989-90 corresponds to the period 1 July 1989 to 30 June 1990).
These state and territory emission estimates are based on national estimates in the National Inventory Report 2021, submitted to the UNFCCC. They are consistent with how the Australian Government will acquit its emission reduction commitments under the Paris Agreement.
