CO₂ calculator

During combustion, carbon atoms separate from light hydrogen atoms and combine a gas with heavy oxygen atoms. Burning 1 L of gasoline creates 1236 L of CO₂ and 1 L of diesel creates 1393 L of CO₂.

Values used for calculations:
Carbon content by weight in C₈H₁₈ (most common component of gasoline): 84.12%
Carbon content by weight in C₁₂H₂₃ (most common diesel): 86.14%
Carbon content by weight in CO₂: 27.29%
Gasoline density 0.75 kg/L = 6.26 lb/US gal = 7.52 lb/imp gal
Diesel density 0.825 kg/L = 6.88 lb/US gal = 8.27 lb/imp gal
CO₂ density 1.87 kg/m3 = 0.117 lb/ft³
