Resolution 3768, Sustainable Evaluation Framework Policy Directive                                    Page 2 of 2

                      EXHIBIT A: SUSTAINABLE EVALUATION FRAMEWORK POLICY DIRECTIVE 

SECTION 1.  Purpose. 
This policy will advance the port’s Century Agenda strategy to be the greenest and most energy
efficient port in North America and the corresponding objectives, including reducing greenhouse
gas emissions by conserving energy and/or using renewable energy.
The Port of Seattle Commission finds that to advance these goals and objectives, it is necessary
to institute a port-wide process that reduces the environmental and societal impacts associated
with capital projects and key operational decisions. The establishment of this Sustainable
Evaluation Framework creates a port-wide process that is efficient and effective, uses port
resources wisely, and provides transparency for the commission, the public, and port staff. 
The primary purpose of this policy is to require the application of the Sustainable Evaluation
Framework to all capital project decisions and key operational decisions to advance the port’s
sustainability goals and objectives. 
SECTION 2.  Definitions. 
When used in this policy directive, the following words and phrases shall have the meanings given
below unless the context in which they are included clearly indicates otherwise: 
“Embodied carbon” is the carbon footprint of a material. It considers how much greenhouse gas
(GHGs) is released throughout the supply chain and is often measured from cradle to (factory)
gate, or cradle to site (of use). 
“Key operational decisions” are decisions about aviation and non-aviationoperations that are
identified by the Executive Director, Senior Director of the Environment and Sustainability Center
of Expertise and/or the director of the affected business unit as in need of review, because the
decisions have energy use implications, GHG reduction opportunities, or other potential
sustainability or societal impacts. 
“Port-wide Sustainability Goals” are identified in Exhibit A. 
“Scope 1, 2, and 3 Greenhouse gas (GHG) emissions” refers to the GHG Protocol Corporate
Standard that classifies a company's GHG emissions into three 'scopes.' Scope 1 emissions are
direct emissions from owned or controlled sources. Scope 2 emissions are indirect emissions
from the generation of purchased energy. Scope 3 emissions are all indirect emissions (not
included in Scope 2) that occur in the value chain of the reporting company, including both
upstream and downstream emissions.

              “Sustainable Design Approach”is the recommended categories and sustainability concepts,
approaches, and ideas that staff expect to explore and evaluate for a given capital project. The
Approach is developed by the Sustainable Project Assessment and Review Collaboration (SPARC,
described below) during the planning phases of a given project and will be used by the respective
project design teams to inform their assessments and analyses to focus on those areas that may
provide significant sustainability benefits for that project. 
“Sustainable Design Strategy” is the recommended course of action that a project team is
expected to implement in constructing its proposed project. The Sustainable Design Strategy
includes the results of the analyses conducted during the design phase of the project and
recommended suite of actions, including potential alternatives that were analyzed in the
Sustainable Design Approach, that are expected to advance the port’s sustainability goals as
appropriate for that project. 
“Sustainable Evaluation Framework” refers to a set of criteria recommended and adopted by the
Commission (Motion 2017-14, adopted December 19, 2017) to assist the port in achieving its
sustainability goals. The criteria are in addition to other project evaluation criteria such as return
on investment or total cost of ownership. 
The Framework criteria are: 
• Reduce GHG emissions 
• Protect health and the environment 
• Increase resilience 
• Support local economic development 
• Advance innovation 
• Leverage and develop partnerships 
• Advance equity 
“Sustainable Project Assessment and Review Collaboration” (SPARC) refers to a group of internal
and external experts as appropriate, determined by the port as having professional expertise
related to the sustainability opportunities relevant to a given port capital project or key
operational decision.
SECTION 3.  Scope and Applicability. 
This policy directive establishes guidance on integrating sustainability into all capital projects and
key operational decisions across the port, in an efficient and effective manner. For capital
projects and key operational decisions that meet the threshold for commission action identified
in the Delegation of Responsibility and Authority, all capital project teams and operational staff
shall integrate sustainable approaches into planning, design, construction, procurement, and
other operations consistent with this policy. Leasing shall be considered part of the scope of this
policy per the outcomes of Section 6(G).

                This policy directive ensures that the port will implement an efficient and effective process for
developing and implementing sustainable designs for capital projects; creates a responsibility to
identify key operational decisions that would benefit from a sustainability review; and creates a
process for reviewing and tracking sustainability outcomes from projects for the commission and
public. 
SECTION 4.  Responsibilities. 
The port’s Executive Director or a delegate shall ensure the policy is implemented and adequately 
funded, and that the Sustainable Evaluation Framework is integrated into capital projects and
key operational decisions across the port.
The Executive Director shall also ensure that decisions associated with the application of the
Sustainable Evaluation Framework are transparently documented and publicly exhibited so that
the Port of Seattle Commission can review, in public, alternatives and trade-offs that describe
how a project can meet its GHG and sustainability and other societal goals. 
The Executive Director shall also ensure that the program evaluation meets the purpose and
timeliness identified in Section 6 of this policy. 
SECTION 5. Policy. 
To integrate the framework into capital development design and construction processes and key
operational decisions, the port shall: 
A.  Develop and implement a tiered approach that focuses port resources on capital
projects that have the greatest opportunities to meet the commission’s directive in the
framework: 
(1) Tier 1: Smaller, less complex, projects that would follow port standards and
specifications.
(2) Tier 2: Medium-sized, or more complex, projects that have opportunities for
sustainability benefit would be subject to targeted sustainability analyses and
strategies. Tier 2 projects may receive a cost per ton of carbon calculation. 
(3) Tier 3: Large, or the most complex, projects with significant opportunities that may 
require a sustainability  certification along with other targeted sustainability
analyses and strategies, as applicable. Tier 3 projects will receive a cost per ton of
carbon reduction analysis. 
B.  Establish a team of project-specific experts (referred to as the Sustainable Project 
Assessment and Review Collaboration or SPARC) to le verage port expertise and knowledge of 

Port of Seattle Sustainable Evaluation Framework Policy Directive                                                     Page 3 of 7

               existing and emerging sustainability practices for capital projects and key operational decisions 
to: 
(1) Identify, review, brainstorm, and recommend sustainability concepts and ideas for
project and operational teams to consider and evaluate during the development
and design stage of port projects. 
(2) Encourage project and operational teams to evaluate and consider innovative 
strategies to reduce emissions and energy use beyond traditional approaches. 
(3) Select and apply the relevant Sustainable Evaluation  Framework criteria to
highlight tradeoffs and benefits during development of the Sustainable Design 
Approach and review of key operational decisions. 
C.  SPARC recommendations shall be documented in a Sustainable Design Approach for
each capital project and presented to commission along with the request for authorization for
design funds. 
(1) The Sustainable Design Approach shall include a recommendation as to whether
a project should pursue an applicable third-party sustainability certification.
(2) Capital project teams shall evaluate and quantify the sustainability costs and 
benefits of the Sustainable Design Approaches as part of the design process. 
D.  Capital project teams shall work with the SPARC to develop and recommend a 
Sustainable Design Strategy that includes alternatives that were analyzed in the Sustainable
Design Approach. The Sustainable Design Strategy shall be included in the final construction
authorization for each project. 
E.  The Executive Director or delegate shall consult with the Energy and Sustainability
Committee on alternatives identified in the Sustainable Design Strategy at or before 30 percent
design. 
F.   The Executive Director shall consult the commission on key operational decision
alternatives where there are significant GHG, sustainability, or cost implications. 
G.  The Senior Director, Engineering, Environment, and Sustainability or delegate shall be
consulted regarding any changes to the Sustainable Design Strategy that occur after commission
authorization. The Senior Director shall brief the Energy and Sustainability Committee on those
changes. 
H.  Recognize  project  teams  that  meet  or  surpass  their  project-specific  goals  to
encourage innovation and environmental sustainability achievements.
