Northwest Ports
Clean Air Strategy

In 2007, the Port of Seattle seaport, the Port of Tacoma and Port Metro Vancouver, Canada, initiated the Northwest Ports Clean Air Strategy (Strategy), which was published in January 2008. The Strategy was updated in 2013. The goal of the Strategy is to reduce diesel and greenhouse gas emissions in advance of, and complementary to, applicable regulations.

The ports have worked with the Puget Sound Clean Air Agency, the US EPA, Environment Canada, Washington State Department of Ecology, and industry and community stakeholders to craft and implement the strategy. While the strategy outlines shared performance measures, each port has implemented emission reduction programs appropriate to its operations. Read the update here.

The goals of the Strategy update are:

  • Reduce diesel particulate matter (DPM) emissions per ton of cargo by 75 percent of 2005 levels by 2015, and by 80 percent of 2005 levels by 2020 (reducing DPM decreases human health impacts in nearby communities).
  • Reduce greenhouse gas emissions per ton of cargo by 10 percent from 2005 levels by 2015, and 15 percent of 2005 levels by 2020 to limit contributions to climate change and reduce associated environmental, health and economic impacts).
  • Achieve performance targets for six maritime industry sectors:
    • Ocean going vessels
    • Harbor vessels
    • Cargo handling equipment
    • Trucks
    • Rail
    • Administration

Port of Seattle programs developed to achieve the Strategy goals have included:

Emission reductions are measured by the Puget Sound Maritime Air Emissions Inventory. First published in 2005 and updated in 2011, it is updated every five years to evaluate the success of emission-reduction programs and to guide the development of updated Strategy goals and targets. View the emissions inventory.
