Seaport Air Quality

The Port of Seattle is dedicated to continuous improvement. For seaport air quality, that means aggressively pursuing reductions in maritime-related emissions while maintaining a vibrant harbor.

In 2003, the Puget Sound Clean Air Agency published its first Air Toxics Evaluation. The study highlighted health risks from diesel exhaust. Trade and transportation industries rely upon ships, trains, trucks and cargo-handling equipment to move goods; the majority of the equipment was diesel powered.

Upon identifying the affect of emissions from these activities, the Port of Seattle has been proactively working with regulatory agencies, the maritime industry, and our communities to achieve early emissions reductions and do our part for public health and the environment.

The Port of Seattle was the first in North America to provide infrastructure for two ships to simultaneously utilize shore power and turn off their engines (cold ironing).
