How much fumes does a car produce?

A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.

How long does it take for exhaust fumes to dissipate?

Carbon monoxide has a half-life in a human body of about 5 hours. This means that if you are breathing fresh, carbon monoxide-free air, it will take five hours to get half the carbon monoxide out of your system. Then it will take another five hours to cut that level in half, and so on.

What do cars emit into the air?
