Single-Trip Emissions Calculator
How much CO2 will you generate the next time you drive your car?
(To calculate yearly totals for a recurring trip, click this link to go to the annual calculator)
This page is the same as our annual green savings calculator, but it has been modified to show the environmental impact of a single one-way car trip.
You can also use this calculator as an easy way to figure out your total fuel consumption and CO2 emissions over a period of time — for example, if your car has 80,000 miles on it, enter 80000 as the distance of your trip to calculate the total emissions over the lifetime of the car. Don't use commas.
