CO2 Emissions Per Mile Calculator

Estimate CO2 per mile from MPG, fuel consumption, or EV electricity use. Compare scenarios, convert to per passenger-mile, and calculate trip totals.

MPG → gCO2/mi L/100km → gCO2/mi EV kWh/mi → gCO2/mi Trip & Yearly Totals

CO2 Per Mile Estimator & Comparison

Compute tailpipe or use-phase CO2 per mile, per passenger-mile, total trip CO2, and side-by-side comparisons with export.
