Puget Sound Clean Air Agency

Putting the Brakes on Air Pollution

Although tailpipe emissions contribute two-thirds of our regions’ air pollution problem, the Puget Sound Clean Air Agency cannot directly regulate cars, SUVs, vans or trucks. But we can educate about and encourage air-friendly transportation options for individuals, businesses and government fleets. Because when it comes to what, how, and how often we drive, we all have choices ‑ and the choices we make can make a huge difference for air quality.

Whether its driving less, purchasing a more fuel-efficient car, or opting for a vehicle that runs on biodiesel or electricity instead of conventional fuels – it all adds up to cleaner air.

Read on for more vehicle and transportation choices that reduce pollution, can save money, and are more protective of your health.
