In New York City there are approximately 8 million people, 1.9 million vehicles and consumes approximately 150,000 barrels of gasoline per day.

An idling car uses between 1/5 to 7/10 of a gallon of fuel an hour. An idling diesel truck burns approximately one gallon of fuel an hour. With average U.S. prices for diesel fuel topping $2 a gallon1, that's about $2 an hour wasted.

Idling cars and trucks each year produce 130,000 tons of carbon dioxide, which contributes to global warming. To offset this global warming pollution, we would need to plant an area the size of Manhattan with trees every single year.
