TailpipeWhen you think of air pollution, what’s the first thought that comes to mind? Most people think of images of a factory smokestack, billowing out thick, black smoke, or a large truck on the road whose exhaust pipes spew discolored emissions.

The reality is that while those are sources of air pollution, the everyday gasoline- and diesel-powered vehicles driven throughout the region dump significant amounts of invisible, hazardous emissions into the air we breathe. This polluted air creates countless economic, environmental, and health issues.

Each year in the United States, passenger vehicles (cars and light trucks) and commercial trucks consume more than six billion gallons of diesel fuel and gasoline combined - without even moving. Passenger vehicles account for roughly half of that figure alone. The larger a vehicle's engine, the more fuel it consumes while idling.

Idling your vehicle truly gets you nowhere. Idling reduces your vehicle's fuel economy, costs you money, and creates pollution. Idling for more than 10 seconds uses more fuel and produces more emissions that contribute to smog and climate change than stopping and restarting your engine.
