Question 1 of 3 is open
How much CO2 does a vehicle emit?
Calculate vehicle CO2 emissions from fuel consumption. Enter consistent values, then review the live result and its unit before using it for a budget, trip, or claim.
Which inputs improve the result?
Use an accurate odometer distance, actual fuel volume, current fuel price, and a vehicle-specific efficiency value. Several fill-ups are more reliable than one rough estimate.
Can this result change in real driving?
Yes. Traffic, speed, road grade, weather, tires, cargo, towing, and maintenance can change real-world fuel economy.
