Airliners parked at Seattle-Tacoma International Airport are expected to save 5 million gallons of jet fuel annually, thanks to an $18.3 million FAA project that will pump air conditioning to each of the airport's 73 gates. Currently, jets must burn fuel to power their own air conditioning units while parked at the gate, emitting some 50,000 tons of carbon dioxide at Sea-Tac alone. "We're thinking big here," FAA Administrator Randy Babbitt said while announcing the grant. "We're quite serious about taking care of the planet."
