Diesel exhaust is the most harmful air pollutant affecting people's health in Washington and contributes 70 percent to the risk of cancer from airborne pollutants. It puts healthy people at risk for respiratory disease and makes the symptoms worse for people with health problems such as asthma, heart disease, and lung disease. Nearly five million Washington residents live or work close to highways and other major roads where they are likely to be exposed to diesel exhaust.
Clean diesel grant funds can be used to help purchase and install clean diesel technology on public- and privately-owned heavy-duty diesel vehicles and equipment in Washington. By installing clean diesel technology, you help reduce harm to public health.
