There has been an excellent deal of specialising in lowering the carbon footprint of vehicles by using light-weight material in their bodies. Lighter vehicles consume less fuel to run and are therefore play a strategic role in increasing energy-efficiency. Vehicular emissions alone contribute 27 per cent of total CO2 emissions currently. One of the lightest and energy-efficient structural materials, magnesium alloys are potential candidates to exchange steel and aluminium alloys in automotive and aerospace components since their density is two-thirds of aluminium and one-quarter of steel.
