Lightweighting
Alcoa is leading the aluminium industry’s efforts to make aluminium climate neutral.
Alcoa researchers have forecasted that with global projections for the use of aluminium in cars and trucks and the numbers of vehicles in use, aluminium will increasingly become part of the global climate change solution. The aluminium industry has the potential to reach a climate neutral state by 2017.
This means the global warming impacts of aluminium production will be fully offset by the amount of carbon dioxide emissions saved by the use of aluminium in the transportation industry.
Today’s motor vehicles use aluminium in engine parts, panels, electronic systems and wheels. An average aluminium part is 40-50 per cent lighter than a steel part and every 10 per cent reduction in weight leads to a 6-8 percent improvement in fuel economy. Less fuel means less emissions and every kilogram of aluminium used in a car can reduce CO2 emissions by 20 kilograms over the life of the vehicle.
Alcoa is also working with Boeing, Airbus and the car industry to develop new alloys for aircraft and motor vehicles.
