BACKGROUND 
On January 22, 2008, the Port of Seattle Commission adopted the Northwest Ports Clean Air
Strategy, a voluntary and collaborative effort of the Ports of Seattle, Tacoma and Vancouver
(B.C.) to reduce maritime and port-related emissions that affect air quality and climate change in
the Pacific Northwest. Developed in close collaboration with the Puget Sound Clean Air
Agency, Washington Department of Ecology, US Environmental Protection Agency, and
Environment Canada with input from stakeholders, customers, and citizens, the Strategy will
result in emission reductions to further improve air quality throughout the region.
The strategy has three primary emissions reduction objectives: 
Reduce maritime related air quality impacts on human health, the environment and the
economy; 
Reduce contribution to climate change through co-benefits associated with reducing air
quality impacts; and 
Help the Georgia Basin-Puget Sound region continue to meet air quality standards and
objectives.

The Strategy builds on the significant efforts the Ports of Seattle, Tacoma and Vancouver, BC
have invested in emission reductions and establishes common short-term (2010) and long-term
(2015) performance measures for further reducing emissions from cargo-handling equipment,
rail, harbor vessels, ocean-going vessels, and trucks.
