Carpooling Calculator FAQ
- Can I use the calculator for a round trip or only a one-way journey?
- The calculator treats the entered distance as the total trip distance; if you are planning a round trip, simply input the combined mileage for both directions.
- What fuel type should I select if my car runs on diesel?
- Choose the "Other vehicle" option and manually enter your car's specific fuel economy figures, as the preset list focuses on gasoline models.
- How accurate is the CO₂ reduction number shown?
- The net CO₂ estimate is based on average emissions per gallon of fuel and the number of passengers; real-world reduction depends on your vehicle's actual emissions and local driving conditions.
- Does the tool consider tolls or parking fees in the cost calculation?
- No, the calculator only factors in fuel cost based on distance, fuel price, and vehicle efficiency; tolls and parking are not included in the total.
