Air Quality Program

Motor Vehicles

Motor vehicles are one of the main sources of air pollution in Washington. The pollution they cause triggers asthma and is linked to other health problems, including cancer and heart attacks. More than a third of Washington's residents are in an age group that is at risk for health problems from this pollution, or have at least one medical condition that is made worse by it. 

Motor vehicles, along with other transportation-related sources, also produce nearly half of the greenhouse gas emissions in our state. Greenhouse gases cause climate change. Effects of climate change in Washington include reduced snow pack, low summer stream flows, more winter flooding, increased coastal erosion, reduced water supplies for people and agriculture, and further loss of salmon habitat.
