Los Angeles International Airport will receive a federal grant of about $4 million for a project that reduces airport ground emissions.

The city’s Board of Airport Commissioners voted to accept the Federal Aviation Administration grant as part of the Voluntary Airport Low Emissions program, created by Congress in 2004 to help airports meet emissions requirements under the Clean Air Act.

“Anything Los Angeles World Airports can do to reduce the carbon footprint of our airports is a step in the right direction,” BOAC President Sean Burton said.

“Being recognized with a VALE award affirms LAWA’s hard work to create a sustainable and environmentally responsible airport for generations to come.”

The grant will partially fund a $6.5 million project that will feature the installation on nine 400Hz electrical ground power units at aircraft parking slots on the west side of LAX.

Aircraft parked at these slots will draw power from the airport’s electrical supply instead of running the planes’ onboard auxiliary power or diesel ground power unit, which both produce more emissions and noise.
