Material restatement

The 2004-05 greenhouse gas (GHG) emissions totals for the Australian Antarctic Division were materially incorrect, due to a conversion error. Emissions from Antarctic base use of light diesel were reported as being 1 462 653 tonnes, of a total of 1 463 430 tonnes emitted. The estimated correct figure for station emissions should have been 6320 tonnes, reducing the total AAD emissions to 39 765 tonnes. This estimate excludes some sites and activities where robust data cannot be provided, so is likely to be a significant underestimate. This then means that DEH’s total GHG emissions for 2004-05 should be 46 590 tonnes of CO2-e, and not 1 499 154 tonnes.

Case study: managing fuel spills in Antarctica

Technology developed to clean up polluted groundwater-typically from mining or agricultural activities-is being modified to work in Antarctica, to halt the flow of a large plume of diesel split at Casey in 1999. A permeable reactive barrier has been built downhill of the spill, and will be trialled over the next five to eight years for its ability to remove the fuel, which is released from its ice prison each summer when the snow melts.
