Australia's National Inventory Report 2021 is now available.
The report fulfils Australia's greenhouse gas inventory reporting requirements under the United Nations Framework Convention on Climate Change (UNFCCC) and is the first National Inventory Report submitted under the Paris Agreement. Its data provides the basis for tracking progress towards Australia's Paris Agreement emissions reduction targets.
The report provides estimates of Australia's net greenhouse gas emissions for the period 1989-90 to 2020-21 for the energy, industrial processes and product use, agriculture, waste and the land use, land use change and forestry sectors (outlined below in Figure 1), in accordance with Paris Agreement requirements including Intergovernmental Panel on Climate Change emission estimation guidelines.
Australia's net greenhouse gas emissions from all sectors were 464.8 million tonnes (Mt) of carbon dioxide equivalent (CO2-e) in 2020-21. This result shows emission reductions of:
- 27.0 per cent (171.5 Mt CO2-e) from 636.3 Mt CO2-e in 1989-90,
- 24.6 per cent (151.5 Mt CO2-e) from 616.3 Mt CO2-e in 2004-05, and
- 6.0 per cent (29.5 Mt CO2-e) from 494.2 Mt CO2-e in 2019-20.
The National Inventory Report publication provides in-depth information on how Australia measures and reports its emissions. Emissions data from the report are published in an interactive online database: Australia's National Greenhouse Accounts (ANGA). ANGA allows users to download and interrogate historical and projected emissions estimates. It includes the full suite of National Greenhouse Accounts, providing additional information on Australia's regional, industry and gas (raw and CO2 -e) emissions.
The Report forms part of the National Greenhouse Accounts 2021. In the coming weeks the remaining elements of the Accounts will be published; the State and Territory Greenhouse Gas Inventories 2021 and National Inventory by Economic Sector 2021, which disaggregate the National Inventory Report by jurisdiction and economic sector respectively.
