## Did you know…

There are 6 Kyoto greenhouse gases (GHGs), of which carbon dioxide (CO2) is the most prevalent?

In 2008, **13.2 million new cars** were sold in the US alone?

A vehicle with a fuel economy of 19mpg emits approximately *one pound of CO2 per mile*? If driven 12, 000 miles, that’s over 5 tons of CO2 per year!

There are approximately** 250 million vehicles** registered in the US. If each car is driven 12,000 miles and produces an average of 5.5 tons of CO2 per year, that would equal ** 1,375,000,000 tons annually**!

## Picture this:

One ton of CO2 has a volume of 500 cubic meters at standard temperature and pressure.

It would take the average driver *less than* 12,000 miles to fill an Olympic sized swimming pool with GHG emissions.

The average car, driven 12,000 miles, will produce enough GHG emissions in *one year* to fill a 3,000 sq. ft house **3.3 times**!

## Calculations

### Assumptions

1 ton = 1,000 kg

1 ton CO2 = 500 m3 CO2 at standard temperature and pressure

1 kg = 2.2045 lbs

1 m3 = 35.3147 ft3

12,000 miles = the number of miles the average car is driven = 5.5 tons CO2

250,000,000 registered vehicles in the US

Volume (V) = Length (L) x Width (W) x Height (H)

**Olympic swimming pool**

L = 50m, W = 25m, H = 2m

50 x 25 x 2 = 2500 m3 or 88,286.667 ft3

**≈ 3,000 sq. ft house**

L = 11.667m, W = 11.667m, H = 6.061m

11.667 x 11.667 x 6.061 = 825.017m3 or 29,615 ft3

If 1 ton CO2 = 500 m3 CO2, then it will take 1.65 tons of CO2 to fill an 825.017m3 house.

**US transportation emissions**

250,000,000 vehicles x 5.5 tons CO2 = 1,375,000,000 tons of CO2
