We calculate emissions based on your annual mileage, fuel economy (city/highway), and driving pattern percentages. Different fuel types have specific CO₂ emission factors per gallon burned.
Vehicles typically have different fuel efficiency in city vs highway conditions. City driving usually results in lower MPG due to stop-and-go traffic, affecting overall emissions calculations.
Electric vehicle emissions depend on your local electricity grid's energy sources. We use EPA regional emission factors based on your ZIP code to provide more accurate calculations.
Gasoline produces about 19.6 lbs CO₂ per gallon, diesel produces 22.4 lbs per gallon, while electric vehicles' emissions vary by region. Alternative fuels like E85 and CNG typically produce fewer emissions per mile.
You can reduce emissions by driving fewer miles, choosing a more fuel-efficient vehicle, maintaining proper tire pressure, combining trips, and considering hybrid or electric vehicles for your next purchase.
Yes! You can input different fuel economies and fuel types to compare potential emissions from different vehicles, helping you make informed purchasing decisions based on environmental impact.
