Vehicle Carbon Footprint Calculator

Burning one gallon of gasoline produces approximately 8.887 kg (19.6 lbs) of CO₂. Diesel produces slightly more: 10.15 kg (22.4 lbs) per gallon.

The average US car produces about 4.6 metric tons of CO₂ per year. Driving less, improving MPG, or switching to an EV are the most effective ways to reduce emissions.

No. EVs produce zero direct emissions but have an indirect footprint from electricity generation (depending on the energy mix) and manufacturing. However, lifetime emissions are typically 50–70% lower than gasoline cars.
