Australian Scope 1,2,3 Spend based Emission Factors
Derived from Australian Input-Output tables, Australian Greenhouse Gas emission accounts and EXIOBASE data
The emission factor dataset provides Scope 1, 2 and 3 (upstream) emissions in
kiltonnes-CO2eq/Million AUD.
Emission factors are based on AR6 Global Warming Potentials for CO2, CH4, N2O, HFC, PFC and SF6 (see Annex II for the factors used).
The emission factors are currently calculated for 2019 to 2022 based on latest available energy, emissions and economic input-output data. 2023 data is possible to calculate, given funding.
Emission factors are provided for each Australian input-output industry group.
The full description of the calculation is provided on Zenodo.
The dataset covers both Australian emissions and includes emissions embodied in the supply-chain of imports. The coverage of imports is due to a coupling of the Australian input-ouput data to the EXIOBASE multi-regional input-output dataset, updated in 2025.
To facilitate usage, a free CC-BY-SA version is available for 2019 data in basic prices. In order to keep updates funded, more recent data, including conversion from basic to purchaser prices (i.e. inclusion of taxes and margins) is available under a commercial licence. A commercial licence removes the -SA (share alike) requirement of the data.
