National Greenhouse Gas Inventory: June 2018

Main content area
Quarterly Update

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 2018
  • emissions from the National Electricity Market (NEM) up to the September quarter 2018

Key data

Australia's emissions for the year to June 2018 were 2.4 per cent below emissions in 2000 (547.0 Mt CO2-e) and 11.7 per cent below emissions in 2005 (604.7 Mt CO2-e).

Since the peak in 2009 electricity sector emissions have declined by 13.8 per cent (29.3 Mt CO2-e). Emissions in the electricity sector continue to fall, with the quarterly update confirming a decrease of 2.8 per cent since June 2017.

Emissions per capita, and the emissions intensity of the economy, were at their lowest levels in 28 years. Emissions per capita in the year to June 2018 have fallen 37 per cent since 1990, while the emissions intensity of the economy has fallen 60 per cent since 1990 (Figure 1).

National emissions levels for the June quarter 2018 increased 1.3 per cent relative to the previous quarter on a seasonally adjusted and weather normalised basis. Emissions for the year to June 2018 increased 0.6 per cent or 3.4 Mt CO2-e. This increase was mainly driven by LNG production for export, with volumes increasing 18.4 per cent.
