What This Calculator Does

Estimate CO2 emissions from miles driven and fuel economy.

It combines Miles Driven, Fuel Economy, Fuel Type to estimate Total Emissions, Emissions (kg), Fuel Used (gallons).

Formula & Method

Fuel use Gallons=\frac{Miles}{MPG} and emissions CO2_{kg}=Gallons\cdot Factor_{kg/gal}.

Notation used in the formulas: R = Total Emissions; x_{1} = Miles Driven; x_{2} = Fuel Economy; x_{3} = Fuel Type.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.

Inputs Used

  • Miles Driven: Used directly in the calculation.
  • Fuel Economy: Used directly in the calculation.
  • Fuel Type: Used directly in the calculation.
