Driving Carbon Footprint Calculator

Estimate driving CO2 emissions from distance, fuel efficiency, and fuel type.

FormulaFuel used = distance x efficiency / 100; CO2 = fuel used x emission factor

Formula

Driving emissions

Emission factors are broad estimates and exclude vehicle manufacturing, fuel production, and maintenance impacts.

Fuel used = distance x efficiency / 100; CO2 = fuel used x emission factor

1,000 km at 7 L/100 km uses 70 L fuel.
