Emissions Reductions Projects

Emissions reductions form an important part of the Port of Seattle's commitment to the environment.  The projects below together will account for:

  • Reduction of over 60,000 Metric tons of CO2
  • Saving over five million gallons of fuel 
  • Creating 120 jobs

The Voluntary Airport Low Emissions Program (VALE) project will allow aircraft to hookup to pre-conditioned air provided by the airport at each gate. Instead of aircraft running their engines for air circulation; this new system will utilize electric; heating and cooling for the airplane cabin.

Once installed, the project is expected to reduce emissions by more than 50,000 metric tons of CO2, save airlines up to five million gallons of fuel and $10 million in fuel costs per year. The CO2 savings are the equivalent of taking 8,700 cars off the road. The project is expected to create 120 jobs.

Fuel Hydrant System Reduces Fuel Truck Emissions

Since 2005, aircraft fuel has been delivered to the passenger gates via underground hydrants rather than by truck. This reduce 42,000 pounds of carbon monoxide and 64,000 pounds of nitrous oxides every year. Put another way, it's like taking 500 cars off area roads. The fuel hydrant system was a key factor in the Port's receiving the Clean Air Excellence Award from the U.S. Environmental Protection Agency.

Controlling Aircraft Emissions

Controlling aircraft in the immediate vicinity of the terminal is the responsibility of the Airport's "Ramp Tower" (KING 5 news video) opened in 2006. Improving traffic flow between the gates and the taxiways cuts aircraft taxi times and thus reduces emissions by about 5%. This small percentage equals 800,000 gallons of jet fuel saved per year, and 16.9 million pounds (8,500 Tons) of CO2 emissions saved from the environment.
