## How to Calculate Car CO2 Emissions
Vehicle emissions depend on how far you drive and how efficient your car is.
### Formula
**CO2 (lbs) = (Annual Miles / MPG) * CO2 per Gallon**
- Gasoline produces about 19.6 lbs CO2 per gallon
- Diesel produces about 22.4 lbs CO2 per gallon
Divide pounds by 2,204.6 to get metric tons.

Exemple Résolu
You drive 12,000 miles per year in a car that gets 28 mpg.
- Gallons used: 12,000 / 28 = 428.6 gallons
- CO2 in lbs: 428.6 * 19.6 = 8,400 lbs
- CO2 in metric tons: 8,400 / 2,204.6 = 3.81 metric tons
