Learn about the Washington State Ferries Sustainability Action Plan and other ways we're working to be stewards of our environment.

Environmental stewardship and sustainability are integral parts of our Strategic Plan. One of our agency’s six values challenges us to, “Be resource stewards by supporting economic, environmental and community need.”

We have a team of environmental professionals, which includes biologists, cultural resources specialists, permitting specialists and an industrial hygienist, who ensure compliance with local, state and federal regulations and policies to build trust and reduce risk. We strive for “next” practices rather than "best" practices (PDF 2.2MB) as we seek to be a recognized leader in our industry and pursue continuous improvement.

We are proud to meet and, oftentimes, exceed the high standards set for us by state and agency executive leadership:

Sustainability Action Plan

We launched our first Sustainability Action Plan 2019-2021 (PDF 752KB) on Earth Day 2019 as one effort to implement the sustainability recommendations, goals, and actions laid out in our 2040 Long Range Plan.

Our current Sustainability Action Plan: 2021-2023 (PDF 2.1MB) includes more action-oriented focus areas and applies the goal-setting tool of “Objectives and Key Results” to set “challenging ambitious goals with measurable results.” This is a change from our previous Plan, which helped to set a baseline for our subsequent efforts. As with the previous version, we consider the Plan to be a “living document” that will guide our sustainability efforts. Provide feedback on our current Plan by sending us an email.

How are we doing with our efforts?

Energy Performance Plan

Our Energy Performance Plan (PDF 55KB) highlights the efforts we are taking to address energy use with a primary focus on greenhouse gas reduction. The document also serves as our roadmap to achieving zero emissions by 2050.

Green Marine

Green Marine is a voluntary environmental certification program for the North American and European maritime industry. In 2018, we became the first U.S. ferry operator to join Green Marine and we received our first verified certification in 2020. We currently serve on several advisory and governance committees helping to strengthen Green Marine’s rigorous performance benchmarking.

Underwater Noise Mitigation and Management Plan for the Protection of Marine Mammals

In response to the governor's Executive Order 18-02, our continuous improvement for Green Marine and our commitment to the environment, we developed an Underwater Noise Mitigation and Management Plan for the Protection of Marine Mammals (PDF 509KB). This document details the environment that we operate in, the potential noise impacts of our operations and the measures that we are taking to address those impacts. 

Enhancing Cetacean Habitat and Observation (ECHO) Program

The Vancouver Fraser Port Authority-led ECHO Program is an internationally recognized, collaborative effort to reduce the cumulative effects of shipping on at-risk whales in the Salish Sea. We were invited to join ECHO’s Advisory Working Group in 2015. We also serve on several of the program’s technical committees.

Whale Report Alert System

We use Ocean Wise’s Whale Report Alert System (WRAS) to provide our crews with accurate and updated location information for large marine mammals and to report sightings to relay to other mariners. Over the past few years, we’ve been one of the system’s top whale reporters (PDF 557KB), directly helping to protect whales.


Developed and managed by the Institute for Sustainable Infrastructure (ISI), Envision is a consensus based framework for evaluating the sustainability and resilience of infrastructure. Envision is jointly supported by the American Society of Civil Engineers, the American Council of Engineering Companies, the American Public Works Association and the Zofnass Program for Sustainable Infrastructure at Harvard University.

The Envision framework allows infrastructure project proponents to ensure that they aren’t just doing the project right, but that they are also doing the right project. We incorporated the Envision framework into the design, construction and maintenance of our infrastructure projects, and also serve on ISI’s Training and Credentialing Committee for Envision Sustainability Professionals.
