Quarterly Update of Australia's National Greenhouse Gas Inventory for March 2018
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.
This update provides estimates of Australia's national inventory of greenhouse gas emissions up to the March quarter of 2018, and emissions from the National Electricity Market (NEM) up to the June quarter 2018.
Australia's emissions for the year to March 2018 were 1.9 per cent below emissions in 2000 (547.0 Mt CO2-e) and 11.2 per cent below emissions in 2005 (604.7 Mt CO2-e).
Electricity sector emissions have declined by 13.9 per cent (29.2 Mt CO2-e) in the year to March 2018, from the peak recorded in the year to March 2009. Emissions from the NEM for the year to June 2018 decreased 4.4 per cent on the previous year and for the June quarter 2018 increased by 0.8 per cent on a seasonally adjusted and weather normalised basis.
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 March 2018 have fallen 36 per cent since 1990, while the emissions intensity of the economy has fallen 59 per cent since 1990 (Figure 1).
National emissions levels for the March quarter 2018 increased 0.3 per cent relative to the previous quarter on a seasonally adjusted and weather normalised basis. Emissions for the year to March 2018 increased 1.3 per cent or 6.8 Mt CO2-e. This increase was mainly driven by LNG production for export, with volumes increasing 25.4 per cent and values increasing by 38 per cent to a forecast $30.8 billion.
