The Australian Carbon Credit Unit (ACCU) Scheme (formerly known as the Emissions Reduction Fund) registers projects that reduce emissions or store carbon in soils and vegetation. There are methodologies that determine the rules and eligible activities for running an ACCU Scheme project. You can read about the ACCU Scheme methods here.
CO2 in the atmosphere can be reduced ‘by taking advantage of the fact that atmospheric CO2 can accumulate as carbon in vegetation and soils in terrestrial ecosystems’ (Source: UNFCCC). Under the United Nations Framework Convention on Climate Change any process, activity or mechanism which removes a greenhouse gas from the atmosphere is referred to as a ‘sink’. LULUCF refers to human activities that impact terrestrial sinks. LULUCF is the most variable emission sector in Australia’s greenhouse gas accounts. It is subject to fluctuations and revisions as estimates and methodologies vary between different datasets. The Potsdam Institute for Climate Impact Research has a useful explanation on why it does not include LULUCF in global emissions data.
This site brings together multiple datasets. Sometimes, that leads to different totals in different places. A good example of this is Australia’s total emissions. We track Australia’s emissions by sector, industry, and state and territory. Each of these result in a ‘total’ emissions for that category. The best place to view Australia’s total emissions is by sector. This is because sector emissions are updated more often (quarterly).
