Seattle-Tacoma International Airport


Greenhouse Gas Emissions Inventory - 2006

EXECUTIVE SUMMARY

The Port of Seattle has voluntarily prepared a greenhouse gas emissions inventory associated with its
Aviation Division. To date, an industry accepted methodology to prepare airport-related greenhouse
gas inventories has not been prepared. Thus, the Port of Seattle is leading the airport community in
the identication of the appropriate boundaries for quantifying Aviation Division emissions.

The protocol used in this analysis, while not complete, represents a substantial improvement in the
data examined for Seattle-Tacoma International Airport (Sea-Tac) to date and is intended to guide
emission  reduction  plans  and  future  inventories.   It  relies  on  methods  published  by  the
Intergovernmental Panel on Climate Change (IPCC), the US Environmental Protection Agency, the
World Resource Institute (WRI) and the International Council for Local Environmental Initiatives
(ICLEI). Where data is not available at this time, this report notes the status and how the availability
(or lack thereof) could affect the results.  For instance, because emissions for non-carbon dioxide
greenhouse gases (such as methane and nitrous oxides) are not available for all sources, this report
focused exclusively on carbon dioxide (CO2) emissions.

This  inventory was  prepared  reecting two  emerging themes  for  identifying the  boundaries
associated with greenhouse gas inventories: organization boundaries and operational boundaries.  In
the case of the Airport, the organization boundaries were limited for this review to the Port's
Aviation Division activities and associated emissions.  Operational boundaries reect to direct,
indirect, and optional emissions for the Aviation Division.  Direct emissions are from sources that
are owned and controlled by the Aviation Division (terminal buildings, mobile sources, and the
power required to operate these resources).  Indirect and optional emissions are a consequence of the
activities of the Port's Aviation Division, but occur at sources owned and controlled by another party.
At an airport, these indirect and optional emissions are associated with the airlines, tenants, and
general public that use that airport.

Port of Seattle Aviation Division owned/controlled emissions represent about 66,491 metric tons of
C02 in 2006. The largest portion of greenhouse gas emissions that the Port owns and controls is that
associated with lighting and heating airport facilities, followed by passenger vehicles on the on
airport roads, Port ground vehicles, and hotel and parking lot shuttles traveling on-airport roads.

Airline/tenantowned and controlled emissions represent million metrictons of CO2 in 20%lAs
would be expected, aircraft represent the single largest source?ofC02 'emissionE'Over 90% of the
airline emissions are from aircraft operating above 3,000 feet. All of the public-owned and controlled
emissions reect onroad travel associated with airport activity: either through vehicular
access by
passengers, hotel/parking lot shuttles off-airport, and airport employee work commute.  0f airportrelated
emissions, public owned/controlled emissions represent 373,033 metric tons of C02 in 2006.

Next Steps:  This report identied a number of steps that the Port can take to improve its future
Aviation Division greenhouse gas emission inventory. These steps primarily focus on collecting data
concerning airport activities in a way that enable the emissions to be identied by ownership and
control. This inventory can also assist the Port with identifying emission reduction actions.
