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 2030.
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.  The use of aluminium in transport provides lifecycle benefits from improved performance, fuel efficiency and lower greenhouse emissions.  Every kilogram of aluminium used in a car potentially saves a net 20 kilograms of greenhouse gas emissions over the car’s life.  For other vehicles, such as trains, ferries and aircraft, the potential savings are even greater.
An aluminium component is 40% – 50% lighter than an equivalent steel component.   And every 10% reduction in weight produces 6% – 8% in fuel savings, with a consequent reduction in vehicle greenhouse emissions.

Alcoa is working with Boeing, Airbus, and the car industry to develop new alloys for aircraft and motor vehicles.
