Committed to sustainable, responsible growth
The Northwest Seaport Alliance is committed to responsible, sustainable growth that protects public health and the environment. We play an important role in the green supply chain and recognize our responsibility extends beyond our customers to the communities where our ports reside.
The gateway has consistently been recognized for our efforts to reduce seaport-related emissions through the Northwest Ports Clean Air Strategy, clean up legacy contamination, restore habitat and find innovative solutions to manage stormwater runoff.
We also have purchased offsets support renewable green power projects in Washington and Oregon and demolition projects aim to recycle 90 percent of materials.
Improving Air Quality
Northwest Ports Clean Air Strategy
The Northwest Ports Clean Air Strategy is a collaborative effort between the ports of Seattle, Tacoma and Metro Vancouver, B.C., to reduce seaport-related air emissions in the Georgia Basin and Puget Sound airsheds from cargo-handling equipment, rail, harbor craft, ocean-going vessels and trucks.
Developed in 2007, the Strategy was updated in 2013 with new goals based on the results of the 2011 Puget Sound Maritime Air Inventory. The goals aim to reduce diesel particulate emissions per ton of cargo 75 percent by 2015 and 80 percent by 2020, and greenhouse gas emissions per ton of cargo 10 percent by 2015 and 15 percent by 2020.

Clean Truck Programs
The North and South harbors' Clean Truck Programs require trucks serving Seattle and Tacoma terminals to have newer, cleaner-burning engines to reduce diesel emissions. Learn more about the:
Cleaner Fuels for Ships
Shipping lines use lower-sulfur fuels to reduce vessel-related emissions, and Totem Ocean Trailer Express is converting to cleaner-burning LNG-powered ships. The North Harbor's At-Berth Clean Fuels program eliminated more than 860 metric tons of sulfur dioxide.
Protecting Water Quality
Our innovative technologies such as biofiltration, bioretention and oyster shell inserts treat industrial stormwater runoff to prevent pollution in our harbors.
Nearly 200 acres of restored habitat and organically managed public parks provide valuable green space for fish and other wildlife as well as people. Many of these sites offer public access points to view the wildlife and the trade-related jobs that support the region.
