EXECUTIVE SUMMARY
In 2024 the Port of Seattle achieved significant progress on our ambitious environmental and
sustainability goals. We're building a greener, more resilient port through a comprehensive
strategy focused on five key pillars:
1. Leadership: Influencing environmental policy and actions locally, nationally, and
internationally.
2. Partnerships: Collaborating with stakeholders to tackle complex challenges.
3. Data-Driven Decisions: Utilizing clear information to guide our actions.
4. Investment: Directing resources toward sustainable practices.
5. Community Engagement and Equity: Working closely with our neighbors to ensure a just
and sustainable future.
The Port boasts a comprehensive set of environmental and sustainability initiatives across air,
water, land, and community. We work to influence change locally and globally, establishing
ourselves as a leader in the aviation and maritime sectors. We recognize our work contributes to
global change and our strategies support progress toward achieving the United Nations
Sustainable Development Goals.
As an organization focused on opportunity, sustainability, and equity, we achieve this by working
collaboratively with others who share our vision. It is also critical that we share our progress
publicly.
This annual report presentation serves a dual purpose:
1. Celebrating Achievements: We'll showcase our comprehensive environmental and
sustainability programs, highlighting significant accomplishments made in 2024.

tenants, and community partners.
Background
In 2024 we released the Port’s first comprehensive Environment and Sustainability Annual Report
showcasing 2023 progress. An annual report allows us to 1) share our comprehensive
environmental and sustainability programs, highlighting significant accomplishments; and 2)
track long-term goals through a set of performance metrics (both qualitative and quantitative).
These metrics, tracked annually, demonstrate our commitment towards goals outlined in the
Century Agenda, regional agreements, and our own programmatic initiatives.
This Port’s commitment to the environment is reflected in the Port's ambitious goals outlined in
the Century Agenda, a 25-year strategic plan adopted in 2012. The Century Agenda serves as a
compass, guiding decision-making and setting a clear course for a greener future. Notably, Goal
4 focuses on environmental leadership, with the Port aiming to become the greenest and most
energy-efficient port in North America.
Century Agenda Goal 4: Be the greenest and most energy-efficient port in North America

Category Summary 2024 Highlights
Charting the
Course to Zero
(Climate)
The Port of Seattle takes a multi-
pronged approach to tackling
climate change and improving air
quality. Decarbonization is a core
focus, with initiatives like switching
to renewable natural gas for
buildings and partnering on clean
fuel research for maritime and
aviation industries. The Port actively
explores alternatives to traditional
fossil fuels, aiming to reduce
reliance on them across its
operations. Additionally,
electrification is a key strategy. The
Port is constantly seeking innovative
solutions to minimize air pollution
and contribute to a cleaner future.
We verified Scope 1 and 2 GHG
inventory through The Climate
Registry.
Increased our renewable natural
gas energy use by 6% (Scope 1 &
2).
Became the first port to require
shore power usage by homeport
cruise vessels in 2027.
Pier 66 shore power project
completed.
47% of cruise calls connected to
shore power.
Decreased APU emissions by 15%
compared to 2023, our lowest
since 2018 (excluding 2020).
53 light duty electric vehicles in our
fleet.
Completed research on SEA's
Ground Transportation Emission
Reduction Strategy.
Note: 2024 emissions data will be
available in early Q3 of this year.
Stewarding
Healthy Lands
and Habitat
The Port is voluntarily taking action
to restore critical habitat and
increase public access for our
communities. We are creating a
lasting legacy of stewardship that
fosters the health of our
communities and region for
generations to come. Our work
supports the survival and recovery
of critical species like salmon and
We adopted the SEA Land
Stewardship Plan and Tree
Replacement Standards.
Reached a landmark deal to sell
500 habitat mitigation banking
credits.

orcas, while also enhancing the
health of our communities through
improved environmental quality and
enriching recreational opportunities
like waterfront parks, inland creeks,
and marinas.
We've also restored kelp beds,
stabilized shoreline, and planted
2,444 trees and shrubs.
Cleaning Up
Contaminated
Lands
The Port of Seattle transforms
historically polluted areas into
healthy lands near our airport and
waterfront, fostering economic
growth and environmental
stewardship.
Became the first U.S. airport to use
cleaning technology to remove
PFAS-containing foam from
firetrucks. This equated to 3,795
gallons removed from SEA.
Significant progress was made with
investigations at seven Port
locations, including East Waterway,
Terminal 25, and Terminal 91. We
also tested new soil treatment
technology at Terminal 25.
Reducing Waste Operating a major airport and
seaport means there can be a lot of
waste. The airport alone is a 24/7
operation that serves over 50
million passengers a year and has
20,000 employees who work there.
It is akin to managing a city,
including the need to manage all the
waste. The Port actively works to
embrace the call to “reduce, reuse
and recycle” in all our facilities.
We are close to our 60% diversion
goal for SEA Airport terminals
(49%) and maritime facilities
(58.6%), both increasing since last
year.
New SEA requirements mandate
reusable or compostable options at
all retail and dining locations, took
effect in July 2024, and has already
led to a 14% increase in waste
diverted to composting.
Building
Resilient and
Sustainable
Infrastructure
Building infrastructure that is
sustainable and resilient in the long
term is important for financial
stewardship, community affects,
and environmental protection. We
need to stop the causes of climate
change while at the same time we
can control and prepare for the
possible impacts. The Port of Seattle
aims to build and maintain its
facilities in a smart, sustainable way
to ensure they function for our
community well into the future.
Through the Sustainable Evaluation
Framework process, we reviewed
137 capital projects, resulting in
two completed sustainable design
strategies.

Environmental
Permitting and
Planning
Securing the necessary
environmental approvals and
permits often requires innovative
solutions and a deep understanding
of the complex and dynamic
regulatory landscape. Port of Seattle
staff navigate these challenges,
integrating environmental
considerations into every stage of
project development.
The draft NEPA document for the
SAMP NTPs was released by FAA
and we held public events for
community awareness and
engagement.
Efficiently handled environmental
reviews and permits, supporting
280 active maritime and aviation
projects in 2024.
Protecting
Water Quality
Port of Seattle implements
programs and processes,
collaborates with our tenants, and
invests in innovative treatment
technologies to ensure we avoid or
minimize any effects on the health
of Puget Sound and foster a clean
and vibrant marine environment.
We protected water quality
through stormwater management
and met all seaport permit
requirements in 2024.
Maritime parks retained its
Salmon-Safe certification, and we
made significant progress (42%)
toward our 75% target for
rehabilitating our maritime
stormwater system.
Lessening the
Impact of
Aircraft Noise
Seattle-Tacoma International
Airport (SEA) was one of the first
airports in the country to establish a
noise mitigation program. Since
1985 the Port has been delivering a
comprehensive Airport Noise
Program to minimize noise pollution
around the airport. The program has
three main components: residential
sound insulation projects, airline
collaboration and recognition, and
community engagement.
Initiated Part 150 study which
included three public workshops.
Launched a Sound Insulation
Repair and Replace Pilot Program
and completed a comprehensive
assessment.
Completed or made progress in
insulating three single-family
homes, 9 apartment buildings, and
3 places of worship.
Engaging Our
Community
Recognizing that a healthy
environment is vital for both the
port and surrounding communities,
the Port of Seattle prioritizes
collaborative environmental
stewardship. Through education
and outreach programs, the Port
empowers near-port residents and
regional communities to participate
We hosted or participated in over
75 community stewardship events
and learning opportunities,
including 50+ habitat events and
tours, and 18 tour showcasing our
PFAS transition.
The Port awarded $226,631 in
funding for the fourth cycle of the

environmental well-being. This
commitment to community
engagement fosters trust,
empowers informed decision-
making, and harnesses the power of
collective action for a more
sustainable future.
South King County Community
Impact Fund to six organizations
serving communities around SEA.
Practicing
Equity,
Diversity, and
Inclusion
The Port actively advances Equity,
Diversity, and Inclusion (EDI)
through its environmental
programs. This includes prioritizing
business inclusion programs that
empower diverse-owned
businesses, fostering green job
creation, and providing a pathway
to economic opportunity for
residents, with a particular focus on
under-represented communities.
Additionally, the Port champions
environmental justice initiatives
that address historical disparities in
environmental burdens.
Supported strong WMBE
contracting goal.
Utilized the equity index in
environmental program planning,
including Part 150, the Land
Stewardship Plan, and the sound
insulation pilot.
Port-funded pre-apprenticeship
training programs trained and
placed 23 community members
into apprenticeships focusing on
clean and renewable energy,
including the construction,
installation, maintenance, and
operation of these systems.
Awards and
Recognition
Throughout the year, we've strived
to implement innovative solutions
and collaborate with stakeholders
to achieve our sustainability goals.
These awards and
acknowledgements represent the
dedication and hard work of our
team and partners, and further
motivate us to continue on the path
of environmental stewardship and
community engagement.
We participate in Green Marine, a
program for continuous
improvement in environmental
performance within the maritime
industry, ranking 5 (the highest
score) in nearly all categories.
The Seattle 2030 District has
awarded the Port of Seattle its
Leadership Vision Award for the
Port's Sustainable Evaluation
Framework.
A complete annual report detailing our progress will be available on the Port's website.
