Core Features
OZ-EFs is built using environmentally extended multi-regional input-output (EE-MRIO) analysis. Vector Sustainability combines Australian Bureau of Statistics input-output tables and Australian greenhouse gas accounts with EXIOBASE, allowing the model to trace emissions generated domestically as well as through international supply chains supplying Australian consumption. Its main characteristics include:
Australian-Specific Factors: Factors reflect the structure and emissions intensity of the Australian economy, including locally significant differences in areas such as electricity, agriculture and mining.
Full Industry Coverage: Factors are provided across the Australian input-output industry classification, allowing expenditure to be mapped to the industry supplying a purchased good or service.
Imported Emissions: Coupling the Australian model with EXIOBASE captures emissions embodied in imports instead of assuming that imported products share Australian production characteristics.
Purchaser-Price Factors: The standard dataset uses basic prices, while purchaser-price extensions are available commercially to incorporate elements such as taxes and margins.
Australian-Dollar Calculator: Vector Sustainability provides a browser-based calculator for selecting an industry and converting AUD expenditure into estimated emissions; it can also process multiple expenditure lines through CSV upload.
Closing Insights
The OZ-EFs dataset addresses a particular problem in Australian carbon accounting: international or generic spend factors may not adequately represent the country's production and consumption patterns. Australia's electricity mix and emissions-intensive mining and agricultural sectors can materially affect expenditure-based estimates, while its reliance on international supply chains makes the treatment of imports equally important. OZ-EFs combines Australian economic and greenhouse-gas accounts with EXIOBASE specifically to capture both sides of this picture.
Potential applications extend beyond estimating purchased-goods emissions. Businesses can use procurement records to estimate Scope 3 emissions where detailed supplier data is unavailable, identify emissions hotspots and prioritize categories for more detailed data collection. Financial institutions can apply the factors in financed-emissions analysis, while carbon-accounting companies can license the data for commercial applications. Vector Sustainability states that the factors are intended for GHG Protocol Scope 3 accounting and can support disclosures aligned with Australian Sustainability Reporting Standards (ASRS), ISSB IFRS S2 and CDP, as well as PCAF financed-emissions accounting.
As of August 2026, the OZ-EFs dataset covers 2019–2023, with new years to be added as underlying ABS and national greenhouse-gas data become available. Qualifying universities, research institutions, NGOs and government bodies can use the current release non-commercially under its specified licence; commercial and contracted uses require a separate licence.
