The aluminum industry is struggling to meet its own voluntary targets to cut direct greenhouse gas emissions from its production processes by 2010, Reuters reports.
One of the International Aluminum Institute’s voluntary objectives is to produce one tonne of primary aluminium using 14.5 megawatt hours of energy. Some older smelters use around 19 MWh/t. Best practice for smelters being installed today is about 13 MWh.
The aluminium industry had met the target of reducing one of the most critical greenhouse gases, perfluorocarbon (PFC), by 78 percent by 2005 from the baseline scenario in 1990. At the same time, primary production increased by 64 percent from 1990 through 2005.
With production doubling it would be difficult for the industry to cut greenhouse gas emissions, independent consultant Jerry Marks told a Metal Bulletin conference in Brussels.
