Sea-Tac takes on this new technology as an already impressive environmental example – it gets around 90 percent of its power from hydro-electric dams in the region.
Excerpt from Transportation Issues Daily
Sea-Tac Airport is changing how it cools and heats planes at the gate, which will reduce emissions and fuel use. The Seattle area airport will deliver Pre-Conditioned Air (PC Air) through a centralized plant to aircraft during boarding and deplaning. No longer will planes have to use their auxiliary power, which emit CO2 gases and other emissions and add to airline fuel costs. The project is expected to be completed by the end of 2013.
Annual emissions will be reduced by 40,000 metric tons, “the equivalent of taking 8,000 cars off the road,” and airlines fuel consumption will drop by an estimated five million gallons.
