Letters sent to FAA and state congressional
delegation
Letter sent to EPA supporting regulation of
aircraft GHG emissions
Mark Reis Testimony before Congress
Participation in the Commercial Aviation
Alternative Fuels Initiative
Participation in ICAO working group
Promotion of NextGen aircraft navigation

Targets to Reduce Emissions
Three Major Sources of Emissions:
POS owned/controlled emissions
Airline owned/controlled emissions
Public owned/controlled emissions

POS Owned/Controlled Emissions
Recommended Goal:
Reduce emissions by 15% below 2005 levels
by 2020
Recommended goal is:
Equivalent to regional goal adopted by the
Western Climate Initiative, and
Consistent with state target adopted in ESHB
2815 (Reduce statewide emissions of
greenhouse gases to 1990 levels by 2020)

Emission Reductions Needed to
Achieve Recommended Goal

Year

Emission Reduction Initiatives
Reductions completed since 2005
Total Reductions ~8,450 tons
Green Tag Energy Purchase ~6,620 tons
Fuel Hydrant System ~980 tons
Recycling Program ~800 tons
Garage Floor Count ~50 tons

Emission Reduction Initiatives
Future Initiatives will require ~24,550 tons reduction
Additional reduction initiatives have been identified,
however precise path to achieving goal remains unclear
Achieving goal will require sustained commitment
Possible future reduction initiatives include:
Energy conservation efforts
On-site alternative energy development
Continuous efficiency improvements to infrastructure and IT
Telework
Shuttle consolidation
Offsets

Airline Emissions
Staff has identified a number of emission
reduction projects
Implementation requires infrastructure
improvements, the cooperation of the airlines,
and in some cases cooperation and approval of
the FAA
Staff has proposed to airlines the development a
work plan for implementing cost-effective
emission reduction projects
Airlines are to present their proposed strategy
for working with the POS on emission reductions

Airline Emission Reduction Projects
Pre-Conditioned Air
FAA grant money secured. Implementation expected 2010-2011
Projected emission reduction: 40,000 tons annually
Gate Electrification
Ongoing
Projected Emission Reduction: 11,000 tons annually
GSE Electrification
FAA grant money secured. Implementation expected 2010-2011
Projected Emission Reduction: 20,000 tons annually
Third Runway Activation
Projected Emission Reduction: 50,000 tons annually
CDA
Port, Alaska Airlines, Boeing, FAA involvement. Implementation within next several years
Projected Emission Reduction: 50,000 tons annually

Public Owned/Controlled Emissions
Public emissions are inherently challenging for
the POS to affect given:
Public preferences
Lack of jurisdiction over area transit and roads
Public emissions are exclusively transportation
related
Transportation emissions are commonly
benchmarked through reductions in vehicle
miles traveled (VMT)

Public Owned/Controlled Emissions
The State of Washington   If Sea-Tac were to adopt
has adopted a          a similar goal for public
transportation specific      emissions related to
climate goal of reducing     airport use it would mean:
total vehicle miles
traveled 18% by 2020,
2005 VMT baseline ~162,318,863
30% by 2035 and 50%    Projected 2020 VMTs ~ 208,000,000
reduction by 2050 (State    VMT level to meet goal ~133,101,467
goal adopted in ESHB     VMT reductions needed ~74,898,533
2815)

VMT Reduction Initiatives
Five (5) percent mode shift goal
Mode Choice Survey completed by Aviation Planning
Hotel shuttle consolidation
Phase Feasibility Study Complete
Estimated VMT reduction potential: 800,000 miles
Parking shuttle consolidation
Estimated VMT reduction potential: 2,000,000
Sound Transit - Light Rail
Sea-Tac link opens December 2009
Commute trip reduction
Estimated VMT reduction potential: 175,000 miles
Telework
Estimated VMT reduction potential: 400,000 miles

Public Owned/Controlled Emissions
Ongoing initiatives will likely reduce airport related VMTs
by ~3,375,000
Achieving statewide goal would require an additional
~70,000,000 VMT reduction
Such a reduction is not feasible for the POS alone
Recommended Goal
The POS will do its part to assist the state, and local
governments in meeting the statewide transportation specific
climate goal of reducing total vehicle miles traveled 18% by
2020, 30% by 2035 and 50% reduction by 2050

Where Do We Go From Here
Developing Climate Action Plan
CAP will consist of five components:
Measurement
Policy/guidance
Emission reduction projects
Adaptation planning
Communicating actions to employees,
business partners, and the public
