PFC (CF4, C2F6, C3F8), HFC (CHF3) and CO2 emissions were estimated from two potlines of the Hydro Australia Kurri Kurri aluminium smelter in the Hunter Valley, NSW, in 2009. Emissions were estimated using integrated sampling over a two week period followed by laboratory analysis for PFCs, HFCs and CO2. The PFC emission factors were similar to, but significantly more accurate than, annual PFC emission factors found for other Australian aluminium smelters (Bell Bay, Tasmania; Portland and Pt Henry, Victoria) in 2009, based on in situ PFC data measurements at Cape Grim, Tasmania. The CF4 and CO2 emission factors at Kurri Kurri are significantly larger than the Australian average CF4 and CO2 emission factors reported to the UNFCCC for 2009. C3F8 and CHF3 emissions at Kurri Kurri are low and do not significantly add to GHG emissions from an aluminium smelter.
