The AusLCI V1.48 database provides emission factors for Australian products and services. This is the latest version, released by the source in May 2026.

The source provides two impact indicators: "Climate change - CN" which is the Carbon Neutrality approach and "Climate Change - Total" which is the -1 / +1 approach. The Carbon Neutrality numbers should be used unless there is a specific need for the -1 / +1 approach; these are used by default in endpoints.

The total and biogenic emissions under -1/+1 approach appear to include uptake of carbon dioxide into short-lived carbon pools such as crops and other plants. This approach would be unusual; this uptake is typically characterized as zero as it is part of the short-term carbon cycle.

The source provides more impact indicators, as well, including “Fossil Carbon”, “Biogenic Carbon” and “Land Use Change”.

Biogenic CH4 emissions are a calculated field. They are the residual between the total Carbon Neutrality emissions and the sum of fossil and land use change emissions, divided by 28 (the AR5 GWP for non-fossil methane).

Biogenic carbon content cannot be reliably back-calculated from the reported figures due to rounding and the possible inclusion of crop residues or soil carbon.

The source website gives detailed information on the inputs and processes behind each emission factor: https://www.auslci.com.au/

The Carbon Neutrality indicator (used by default in Climatiq) is likely to be the most appropriate choice, unless you need the -1/+1 indicator for a specific reason.

The emission factors, in common with other datasets using the same allocation approach, may include negative values due to an expanded system boundary where credits are given for avoided impacts elsewhere (e.g. methane use for power generation avoids flaring, recycling steel avoids use of virgin materials). This results in a negative value for the net emission factor when these credits are greater than gross emissions.
