Quarterly Update of Australia's National Greenhouse Gas Inventory: March 2017 (incorporating June 2017 quarter emissions from the National Electricity Market)

Department of the Environment and Energy, 2017

Australia's National Greenhouse Accounts

Australia's National Greenhouse Accounts are made up of a series of comprehensive reports and databases that estimate, and account for, Australia's greenhouse gas emissions. These publications fulfil Australia's international and domestic reporting requirements. The Quarterly Update of Australia's National Greenhouse Gas Inventory is a publication series that reports on the latest estimates of Australia's national greenhouse gas inventory.

The Quarterly Update of Australia's National Greenhouse Gas Inventory: March 2017 (the Quarterly Update) provides estimates of Australia's national inventory of greenhouse gas emissions up to the March quarter of 2017, and electricity emissions from the National Electricity Market (NEM) up to the June quarter 2017.

For the June quarter 2017, emissions from the NEM decreased by 2.8 per cent on a seasonally adjusted and weather normalised basis, and decreased 2.3 per cent in the year to June 2017 when compared to the previous year.

Australia's annual emissions for the year to March 2017 are estimated to be 550.1 Mt CO2-e. This figure is 0.8 per cent below emissions in 2000 (554.4 Mt CO2-e) and 9.1 per cent below emissions in 2005 (605.0 Mt CO2-e).

For the March quarter 2017, national emissions levels, excluding the Land Use, Land Use Change and Forestry (LULUCF) sector, have increased 1.6 per cent relative to the previous quarter on a seasonally adjusted and weather normalised basis. For the year to March 2017, emissions increased 1.0 per cent on the previous year. The expansion in LNG exports, which saw a production increase of 39.7 per cent over the previous year, was the major contributor to this increase in emissions.

Emissions per capita, and the emissions intensity of the economy, were at their lowest levels in 27 years in 2017. Emissions per capita in the year to March 2017 have fallen 34.2 per cent since 1990, while the emissions intensity of the economy has fallen 58.4 per cent since 1990 (Figure 1).
