Some US Statistics:

  • According to the US Bureau of Transit Statistics, there are 251,000,000 registered vehicles, of which
  • 135,000,000 are passenger cars
  • 99,000,000 are SUV's and pickup trucks
  • A 2006 US Department of Transportation study showed that the average fuel economy of these automobiles is approaching 18 mpg.
  • These vehicles used an alarming 174,000,000,000 gallons of gasoline (i.e. 174 BILLION gallons).
  • Currently, the average US driver drives about 12,000 miles per year (or about 33 miles per day).
  • For every gallon of gas used, 19.6 pounds of carbon dioxide gas is produced.

    • What this means:

  • For our chemistry students out there, one mole of gaseous carbon dioxide corresponds to 22.4 liters at STP, such that every gallon of gasoline burned creates 1030 "gallons" of gaseous carbon dioxide.
  • In other words, each day in the US, our automobiles produce enough carbon dioxide to COVER THE ENTIRE STATE OF MASSACHUSETTS with a 3 inch thick blanket of pure carbon dioxide!

    • What you can do:

    We invite you to calculate your daily automobile emissions here. The US average is 36 pounds per day, or 5.9 metric tons per year!

    Using our simple calculator below, you can calculate your daily emissions, pledge not to drive for a day, and help offset your driving at our pledge page.
