Air Pollution & Your Health
Our long-term vision is for all people to benefit from clean healthy air all the time, everywhere. To achieve this, we target the largest sources of the most harmful pollutants in our region to protect public health.
Threat of Air Pollution
We believe all people would benefit from clean healthy air all the time, everywhere. In our region, particle pollution, smog, and air toxics pose the greatest risk to our well-being. Outdoor air pollution can cause heart attacks, asthma, strokes, cancer, and premature death. An estimated 1,100 people die each year in Washington State due to outdoor air pollution.
Because we are concerned about our climate we also focus on the reduction of greenhouse gases, which are the leading cause of climate change. In our region, climate change will likely lead to warmer, drier summers which increase levels of smog pollution, posing health risks to those with lung and heart diseases.
If you have plans to be active outdoors and are sensitive to air pollution, check the air quality forecast on our website.

Wood Smoke & Your Health
Smoke from fireplaces, wood stoves, backyard and land-clearing burn piles and wildfires contains fine particle pollution, which is one of the most serious air quality problems in the Puget Sound region. Fine particles are tiny, microscopic pieces of pollution that can easily enter your bloodstream and cause breathing and heart problems. The health effects even from short-term exposure are serious, and include:
- Asthma attacks
- Heart attacks
- Premature death
- Strokes
Fine particle pollution is especially dangerous for children, the elderly and people with sensitive immune systems.

Diesel Exhaust & Your Health
What Are the Health Effects of Diesel Exhaust?
Breathing diesel exhaust can cause serious health problems. The tiny particles in diesel exhaust are highly toxic.
Diesel exhaust represents 78% of the potential cancer risk from all air toxics in the Puget Sound area. It is also linked to respiratory and cardiovascular problems, such as:
- Asthma
- Heart attacks
- Strokes
- Premature death
Children, the elderly, pregnant women, and those with compromised immune systems or illnesses are especially vulnerable. Recent studies show people living near ports and roadways have higher exposures and health risk.

What Are the Main Sources of Diesel Exhaust?
The majority of diesel exhaust in the Puget Sound region comes from goods and people movement, which can be broken down into the following transportation sectors:
- Maritime vessels/ships: This sector consists of ocean-going vessels such as container ships, bulk carriers, and articulated tug barges and harbor vessels, such as tugboats, work boats, ferries, fishing vessels, and excursion vehicles.
- Off-road equipment: This sector includes construction equipment, aircraft-support equipment, and cargo-handling equipment used at seaports, rail yards, distribution centers, and waste transfer stations.
- On-road vehicles: This sector consists of trucks, vans, buses, waste haulers, and emergency-response vehicles.
- Rail: This sector consists of locomotives that transport goods and people, including switcher, short-line, and line-haul locomotives.
How Is Diesel Exhaust Being Reduced?
We address diesel pollution through partnerships with other agencies that focus on reducing diesel pollution, administering incentive programs and projects that employ diesel emission reduction technologies, and help inform policies that encourage cleaner, low carbon solutions.
