​Environmental Programs at the Port of Seattle

The Port of Seattle has established a reputation as the Green Gateway. We offer the lowest carbon footprint for cargo shipped by sea and then rail from Asia to the Midwest and the East Coast.

Just as importantly, the Green Gateway stands for the port’s commitment to environmental leadership and award-winning environmental efforts at Seattle-Tacoma International Airport and throughout our maritime operations.

Sea-Tac Airport Progress Reports

Toward achieving the goal of sharing outcomes with the communities we serve, Sea-Tac Airport publishes annual progress reports. The 2014 Progress Report includes five-year results based on the 2009 Environmental Strategy Plan (see column to the right for all reports and the strategy).

We are pleased to report that in 2014 we achieved a number of our 2009 goals. For example, we:

  • Reduced water consumption 5 percent below 2008 levels
  • Achieved Best Management Prectices for water quality and treatment over 100 percent of airport industrial services
  • Introduced best management practices to reduce construction waste
  • Partnered with business operators to promote clean taxis and build infrastructure to reduce aircraft-related emissions. 
Sea-Tac Airport also made progress in the following areas during 2014 when we:
  • Reduced our green house gases by more than 1,500 tons
  • Fueled our bus fleet with renewable natural gas
  • Increased our recycling rate from 23 percent to 31 percent
  • Increased the numnber of projects seeking Leadership in Energy and Environmental Design (LEED)
  • Increased meal donations from 8,000 pounds to over 26,000 pounds or 500 meals per week

25-year Environmental Goals

Adopted in 2011 by the Port of Seattle Commission, the following policies are aimed at being a leader among U.S. ports for environmental stewardship and energy efficiency:
  • Reduce air pollutant emissions by 50 percent from 2005 levels.
  • Lead our industry's greenhouse gas (GHG) reduction strategies by reducing carbon emissions from all port operations by 50 percent from 2005 levels and reducing aircraft-related GHG emissions at Sea-Tac by 25 percent.
  • Meet future growth in energy usage through conservation and renewable sources.
  • Restore, create, and enhance 40 additional acres of habitat in the Green/Duwamish watershed and Elliott Bay.
  • Prevent sprawl in less developed areas of Puget Sound by anchoring our region's urban industrial land use.
  • Ensure all stormwater leaving port operated facilities meets or exceeds agency requirements and create partnerships that lead our industry in stormwater quality improvements.

Both maritime and aviation programs are guided by our commitment to the 25-year goals. We also seek to model sustainable growth, achieve the greatest environmental benefit from our efforts, partner with other organizations in order to leverage financial and professional resources, to see our sustainable practices as a competitive advantage, and to share our environmental outcomes with the community we serve.
