How much CO₂ is produced by burning 1 liter of gasoline?

Burning 1 liter of gasoline generates approximately 2.31 kg of CO₂. Although 1 liter of gasoline weighs only ~0.74 kg, the carbon atoms combine with atmospheric oxygen (molecular weight increases from 12 to 44) during combustion, producing over 3 times the fuel's original weight in CO₂.

How do you calculate total fuel required for a road trip?

Fuel (Liters) = Distance (km) / Fuel Economy (km/L). In US units, Gallons = Distance (miles) / MPG. A vehicle getting 30 MPG traveling 600 miles requires 600 / 30 = 20 gallons of fuel (75.7 liters).
