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.
The majority of diesel exhaust in the Puget Sound region comes from goods and people movement and are broken down into the following four transportation sectors: on-road vehicles, off-road equipment, marine vessels, and rail locomotives.
We're addressing diesel emissions by developing partnerships with other agencies that focus on reducing diesel pollution, administering incentive programs and projects that employ diesel emission reduction technologies, and supporting fleets to understand and implement policies that encourage cleaner, low-carbon solutions.
