A new study shows that choosing aluminium over steel in new automobile construction to improve fuel economy is also the best way to reduce energy consumption and carbon emissions.
The study, conducted by the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), concluded that reducing vehicle weight with aluminium can result in the lowest total vehicle lifecycle environmental impact - cradle-to-grave - as compared to both traditional and advanced steels.
"As the U.S. works to reduce dependence on foreign oil, promote clean energy and combat climate change, this report definitively documents why aluminum offers the most promise for cutting total automotive-related carbon emissions and energy use," said ORNL's Sujit Das, an expert on product lifecycle assessments
