It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air. When gasoline burns, the carbon and hydrogen separate.
A typical passenger vehicle emits about 4.7 metric tons of carbon dioxide per year. This number. can vary based on a vehicleâs fuel, fuel economy, and the number of miles driven per year. The. average gasoline vehicle on the road today has a fuel economy of about 21.6 miles per gallon.
