AirAsia has introduced a new initiative to cut carbon emissions at airports with new ground equipment technology at its main hub at the Kuala Lumpur International Airport (KUL).

At a launch event at KUL Airport, AirAsia and Smart Airport Systems (SAS) demonstrated the use of Combo Units, an advanced piece of airport ground equipment. It offers dual functionality as a Ground Power Unit (GPU) and an Air Condition Unit (ACU), thus providing for the electrical and air-cooling needs of an aircraft while it is stationary on the ground before a flight and during transit.

According to AirAsia, without adequate ground power and a performing ACU an aircraft relies on the use of its auxiliary power unit (APU) to perform the same functions. However, this is cost and carbon-inefficient, because APUs are powered by aviation turbine fuel.
