Clean Coal Technologies in AustraliaA Brief Overview of Research, Development and Demonstration John Carras Chairman – Australian Consortium of the IEA GHG Programme Technical Forum, 16 October 2007, Daejeon Korea
Australia’s Greenhouse Gas Emissions • Australia emitted 559 M tonnes CO2 equiv. (2005) • Australia has not signed the Kyoto Protocol but has committed to the Kyoto target of a 108% increase over 1990 emissions (to 2012) – currently on track • Australia’s greenhouse gas intensity (per capita) at ~27 tonnes CO2 – equiv. per capita is among the highest in the world • Australia’s greenhouse gas intensity (per $ of GDP) is 0.7 kg CO2
Importance of Coal to Australia • Black coal is Australia’s largest commodity export and is worth $25 billion (AUD) per annum • Australia is the world’s largest exporter of coal • Electricity generation accounts for ~35% of Australia’s net GHG emissions • Australia’s electricity derives mainly from coal (57% black coal, 30% brown coal)
