SUBJECT:  Sustainable Project Framework Briefing and Recommendations 
EXECUTIVE SUMMARY 
The purpose of this briefing is to present the findings and recommendations for the Port's
Sustainable Project Framework Initiative.  Staff conducted this initiative in response to the
Commission directive to integrate sustainability into capital projects in a way that incorporates
the following goals (including Century Agenda) into decision-making processes:1 
Reduce GHG emissions and increase energy system resilience 
Protect public health and the environment 
Advance innovation 
Leverage partnerships 
Support local economic development 
Advance race and social justice.
Recommendations include new procedures to evaluate sustainability in capital projects, 
including screening projects as a way to focus limited resources on projects with the greatest
opportunities  and using a more systematic and structured approach for evaluating and
implementing sustainability strategies for each project.  In addition, staff will present an
opportunity to use an innovative new tool designed to reduce embodied carbon in construction
materials.   Lastly,  staff  will  present  estimated  resource  needs  along  with  a  proposed
implementation plan and schedule. 
The Energy and Sustainability Committee, chaired by Commissioners Felleman and Calkins, has
been briefed on the proposed Sustainable Project Framework and recommends proceeding
with the development of a policy directive based on these staff findings. The policy directive is
scheduled for introduction on October 8, 2019 and adoption on November 12, 2019.

FINDINGS AND PROPOSED APPROACH 
Staff conducted extensive research and analyses over the past year including evaluating our
current approach to integrating sustainability into Port capital projects, interviewing staff,
reviewing a range of sustainability certification systems and determining which ones apply to
Port goals as well as projects, and developing new procedures to integrate sustainability into
Port projects.
Based on the outcome of this research, staff recommends several key policy elements and
procedures to integrate sustainability across capital projects in an efficient and effective
manner. These new procedures begin with a tiered approach for capital projects that focuses 
on evaluating projects that are expected to provide sustainability benefits in key areas such as
reducing carbon or energy use.  Under this system, projects would fall under one of three
categories: 
Tier 1: Smaller projects that would only follow Port standards and specifications 
Tier 2: Medium-sized projects that have opportunities for sustainability benefit would
be subject to targeted analyses and strategies 
Tier 3: Large projects with significant opportunities would require a full sustainability
certification along with other sustainability strategies as applicable 
The tiered approach will apply to all capital projects, including projects that wouldn't
traditionally be subject to LEED.  The criteria used to classify projects among the tiers will be
adjusted and revised as the Framework is piloted throughout 2020.
For projects determined to be Tier 2 or 3, staff will convene a committee of internal subject
matter experts (referred to as the Sustainable Project Assessment and Review Committee or
SPARC) at the beginning of the project to review and brainstorm sustainability options for those
specific projects. These options will comprise the Sustainable Design Approach for that project,
which would be provided to Commission along with the request for design funds.
If the project moves forward to design, sustainability staff would work with the project team to
evaluate the costs and benefits of the sustainability options during the design process.  The
project team would then finalize the recommended sustainability strategies into a Sustainable
Design Strategy for that project. This document would include the description of the strategies,
the costs and benefits, any potential trade-offs, and project-specific sustainability targets. The
strategy would be provided to Commission as the project team requests approval to begin
construction. 
NEW PARTNERSHIPS AND INNOVATION 
Staff will also present a new and innovative opportunity to provide incentives to reduce carbon
in construction materials through a partnership with the University of Washington's School of
Architecture, SKANKSA, and Microsoft. Staff recommends working with these regional leaders
to develop and pilot their new tool, the Embodied Carbon in Construction Calculator (EC3) tool.

This tool calculates embodied carbon from a range of construction materials and can be used to
compare materials across potential suppliers based on the potential for reducing embodied
carbon in the construction materials.
COST ESTIMATES 
Staff estimate that the proposed new procedures will require two additional FTEs, one for
Maritime and one for Aviation to assist capital project teams in researching and identifying new
sustainability  options,  conducting  additional  carbon  and  energy  calculations,  developing
targets, and tracking projects through the process.  The requested FTEs are included in the
proposed Maritime and Aviation 2020 operating budgets. 
As shown in the proposed framework, staff anticipates no increased costs in 2020 for Tier 1
projects and potential for some increased costs for Tier 2 projects.  Similarly, there may be
additional costs for Tier 3 projects, depending on the new sustainability strategies or attributes 
that would be in addition to those required to achieve LEED.
SCHEDULE AND IMPLEMENTATION PLAN 
If Commission approves the proposed approach, staff will finalize the proposed framework
guidance materials and implementation plan by the end of Q4 2019. Beginning in Q1 2020 (and
subject to availability of staff resources), staff will conduct hiring processes, revise tracking
systems, and begin implementing new procedures, including those necessary to efficiently
operate the EC3 tool.
