Quarterly Update Australia's National Greenhouse Gas Inventory: March Quarter 2013
Emissions increased in the March quarter 2013, with trend emissions growing by 0.5%. Seasonally adjusted and weather normalised emissions increased 0.2% on the previous quarter (Figures 1-3).
The primary contributor to the quarterly trend increase in emissions was increases in the fugitive emissions (section 2.4) and stationary energy excluding electricity (section 2.2) sectors reflecting increased economic activity in these sectors. This was partially offset by a trend decrease in emissions in the electricity sector (section 2.1) due to continued declines in electricity demand and changes in the generation fuel mix.
Annual emissions for the year to March 2013 are estimated to be 557.0 Mt CO2-e. This represents zero growth in emissions when compared with the year to March 2012. For the year to March 2013, there was a decline in emissions from electricity (section 2.1), reflecting lower electricity demand and changes in the generation mix. This decline was largely offset by an increase in fugitive emissions (section 2.4), resulting from increased production activity in the coal mining and natural gas sub-sectors.
