EV Carbon Footprint Calculator Online

Feeling guilty about your environmental impact even though you drive an electric vehicle? San Francisco-based carbon-offset company TerraPass can help ease your eco-conscience with their new carbon footprint calculator which has been updated to include the most recent green cars.

Although many electric vehicles themselves do not produce green house gas emissions, the electricity used to charge the cars from the grid certainly plays a role in the addition of pollutants in the atmosphere, which can change depending on where a driver lives, and how their utility produces energy.

TerraPass uses a variety of equations to determine carbon footprint, but the model for electric vehicles is: annual miles driven divided by miles-per-gallon equivalent, multiplied by kilowatt-hours per gallon equivalent, multiplied by greenhouse gas emission factor for kilowatt hours, which is estimated at 1.37 pounds per CO2e per kWh. Got it?

Well, neither do we, but you can input your data on the site to find out how much carbon you’re supposedly emitting.
