Abstract
The worldwide aluminium industry has made good progress in reducing greenhouse gas emissions over the last decade and is now working towards global emission reduction goals to lower perfluorocarbon (PFC) emissions intensity by 80% and smelting energy usage by 10% by 2010 from 1990 levels. The industry is working cooperatively with governments through domestic voluntary programs and globally through voluntary programs organized by the International Aluminium Institute. Depending on the technology type, a further lowering of emissions is both technically and economically feasible for many plants around the world, including regions of rapid expansion such as China and Russia. This paper reviews recent trends in PFC emissions from the global aluminium industry and presents an update of the technical options and costs of reducing PFC greenhouse gas emissions from aluminium production. It also summarizes recent industry efforts to standardize measurement methods, consolidate global data and improve the verification of emissions and emissions inventories.
