Diesel exhaust is a leading source of toxic air pollution in the Puget Sound. People living near major transportation corridors and port areas face the great risk, especially children, older adults, and people with existing health problems.  

Through our Diesel Program, we work with local businesses and governments to develop and employ strategies that reduce diesel pollution.
