The Global Aluminium Industrys Perfluorocarbon Gases Emissions Reduction Programme: Results of the IAI Anode Effect Survey 2009
The 2009 Anode Effect Survey results show a continuation of the trend for significant reductions in perfluorocarbon (PFC) greenhouse gas emissions by the global aluminium industry, on an absolute as well as per tonne of production basis. The almost complete coverage (91％) of the IAI survey data outside China (with respect to both metal production and emissions), combined with the fact that the IAI uses actual measurements and secondary information to make an informed estimate of Chinese industry performance, positions the global aluminium industry inventory very favourably compared to the greenhouse gas inventories of other commodities. Global aluminium industry 2009 PFC emissions (as CO2e) per tonne of production were 29％ lower than those in 2006, well on course to meet the IAI voluntary objective of a 50％ reduction by 2020 on a 2006 baseline. 2009 saw an acceleration in the global industrys annual rate of emissions reduction, due to curbs in production in poorer performing facilities. There has been an 88％ improvement in aluminium industry anode effect PFC emissions per tonne of production since 1990, with 2009 emissions per tonne the lowest since IAI records began. With PFC emissions per tonne slashed by almost 90％ since 1990 and strong growth in aluminium production over the same period, total annual emissions of PFCs to the atmosphere by the industry have been reduced from 96 million tonnes of CO2e in 1990 to 22 million tonnes in 2009, a fall of over 75％ despite a 90％ increase in primary aluminium production, from 19.5 to 37 million tonnes.
