How to Use This Calculator

Enter Annual miles driven, Vehicle type (0=Gas, 1=Diesel, 2=Hybrid, 3=EV), and Base fuel economy (MPG).
Set Vehicle age (years).
Review the CO₂ emissions (tons/year) result.
Use Fuel consumed (gal/year) and NOₓ emissions (g/year) to inform your decision.

How the result changes with Annual miles driven

Annual miles driven: Total miles you drive per year.
Vehicle type (0=Gas, 1=Diesel, 2=Hybrid, 3=EV): 0 = Gasoline car, 1 = Diesel truck, 2 = Hybrid, 3 = Electric vehicle.
Base fuel economy (MPG): Vehicle's EPA-rated miles per gallon when new.
Vehicle age (years): Age of vehicle in years. Fuel economy degrades ~1% per year.

CO₂ emissions (tons/year): Annual carbon dioxide emissions in metric tons.
Fuel consumed (gal/year): Gallons of fuel used annually (0 for EVs).
NOₓ emissions (g/year): Annual nitrogen oxides emissions in grams.
PM2.5 emissions (g/year): Annual fine particulate matter emissions in grams.
Age-adjusted MPG: Fuel economy after age-related degradation.
Est. fuel cost ($/year): Estimated annual fuel cost at $3.50/gallon.
