National Greenhouse Gas Inventory: June 2017

Main content area
Quarterly Update (incorporating September 2017 quarter emissions from the National Electricity Market)
Publication Date: 
December 2017

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 inventory reporting requirements. The Quarterly Update of Australia’s National Greenhouse Gas Inventory reports on the latest estimates of Australia’s national greenhouse gas inventory.

This Quarterly Update provides:

  •  estimates of Australia's national inventory of greenhouse gas emissions up to the June quarter of 2017
  • electricity emissions from the National Electricity Market (NEM) up to the September quarter 2017

Key data

For the June quarter 2017, national emissions levels, excluding the Land Use, Land Use Change and Forestry (LULUCF) sector, have decreased 0.6 per cent relative to the previous quarter on a seasonally adjusted and weather normalised basis.

Australia's annual emissions in 2016-17 are estimated to have increased 0.7 per cent on the previous year to 550.2 Mt CO2-e. The expansion in LNG exports, which saw a production increase of 41.6 per cent over the previous year, was the major contributor to this increase in emissions. Annual emissions are 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 September quarter 2017, emissions from the NEM decreased by 3.2 per cent on a seasonally adjusted and weather normalised basis, and decreased 3.4 per cent in the year to September 2017 when compared to the previous year.

Emissions per capita, and the emissions intensity of the economy, were at their lowest levels in 28 years in 2017. Emissions per capita in 2016-17 have fallen 34.4 per cent since 1990, while the emissions intensity of the economy has fallen 57.8 per cent since 1990 (Figure 1).
