AusLCI Emissions Factors

The AusLCI Carbon Emissions Factors contains emissions data in kg CO2e for the AusLCI database. Data is included for several different impact assessment methods. The Carbon Neutrality Assumption method assumes that all biogenic carbon sequestered (e.g. during growth of agriculture) is eventually released back into the atmosphere, either naturally decomposed or burned, so that there is no net change of atmospheric carbon. As such this method includes factors from sources such as fossil fuels, as well as from biogenic methane, and excludes biogenic carbon. The Total Carbon method includes factors from sources such as fossil fuels as well as from biogenic sources, including biogenic methane. The Fossil Carbon method includes factors only from fossil fuel sources, and excludes biogenic carbon and biogenic methane. The Biogenic Carbon method includes factors only from biogenic sources, including biogenic methane and excludes other sources such as fossil fuels.

All data is available with and without infrastructure included. Infrastructure refers to upstream impacts from capital equipment. E.g. the tractor manufacture in a track operation process, or factory construction in a manufacturing process. **Biogenic refers to impacts from carbon or methane stored in biomass. E.g. combustion of biomass, sequestration from agriculture.
