Freely available Australian data on Scope 3 emissions
The emission factor dataset provides Scope 1, 2 and 3 (upstream) emissions in kiltonnes-CO2eq/Million AUD. Emission factors are provided for each Australian input-output industry group.
The dataset is derived from Australian Input-Output tables, Australian Greenhouse Gas emission accounts and EXIOBASE data.
The dataset covers both Australian emissions and 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.
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, and adjustments can be made to provide estimates for 2024.
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 (e.g. 2020-22 or more recent updates), and extensions such as conversion from basic to purchaser prices (inclusion of taxes and margins) are available under a commercial licence upon request. A commercial licence will also remove the -SA (share alike) requirement of the data. The authors are open to making all data freely open under a longer-term, sustainable funding model.
The full description of the calculation is provided in the attached documentation.
