The number of No Drive Days called in recent years:

Keep in mind that weather plays an important factor in the formation of ozone. (Source: DAQ Air Monitoring)

By simply parking your vehicle for one day, the average driver would keep just over ¼ pound of pollution out of the air. While that may not seem like much, if every driver along the Wasatch Front would park his/her vehicle for one day per week, emissions would decrease by 125 tons that week or 6,500 tons for the year.

When a car is at idle, emissions of carbon monoxide are at their highest. As speed increases, it drops dramatically, but increases again with speeds over 50 mph. (Source: EPA)

Using a gas-powered lawn mower for one hour produces as much pollution as driving your car 50 miles. Using a chain saw for one hour produces as much pollution as driving your car 200 miles. Using an outboard motor produces as much pollution as driving your car 800 miles. (Source: Popular Science, July 1992)
