-Make the air healthier by cutting down on hazardous pollution in your town or community.
-Help the environment. For every 10 minutes your engine is off, you'll prevent one pound of carbon dioxide from being released (carbon dioxide is the primary contributor to global warming).
-Keep money in your wallet and save fuel. Save between 1/5 to 7/10 of a gallon of fuel for every hour of not idling.
What harm does idling do?
There are three main problems with idling:
First, idling pollutes the air and harms health. Idling tailpipes spew out the same pollutants that form unhealthy smog and soot as those from moving cars. Nitrogen oxide, particulate matter, carbon monoxide and volatile organic compounds are the main health-harming pollutants in vehicle emissions. Diesel engines emit more than 40 hazardous air pollutants.
These pollutants have been linked to serious human illnesses, including:
-chronic bronchitis and
Children, the elderly and those with asthma and other chronic health problems are especially vulnerable to the health dangers of exhaust.
Pollution from idling contributes to global warming. Idling cars and trucks emit carbon dioxide (CO2), a main heat-trapping gas. In New York City alone, idling cars and trucks each year produce 130,000 tons of carbon dioxide, a new EDF report shows (see Idling Gets You Nowhere [PDF]). To offset this amount of global warming pollution, we would need to plant an area the size of Manhattan with trees every single year.
Idling wastes fuel and money. An idling car uses between 1/5 to 7/10 of a gallon of fuel an hour. An idling diesel truck burn approximately one gallon of fuel an hour. With average U.S. prices for diesel fuel topping $2 a gallon (as of 2/2/09), that's about $2 burned.
