Quarterly Update of Australia's National Greenhouse Gas Inventory: December Quarter 2012
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 recent declines in electricity demand and changes in the generation fuel mix.
Over the first two quarters of 2012-13 national inventory total seasonally adjusted and weather normalised emissions were lower by 0.2% compared with the same period in 2011-12. Sectors covered by the carbon pricing mechanism were 1.0% lower largely reflecting lower electricity emissions (-7.2%) while the stationary energy excluding electricity (+4.3%), industrial processes (+1.6%) and fugitive emissions (+16.8%) sectors showed growth in emissions in reponse to improved economic conditions.
