Electric Road Trip

What's the carbon footprint of EVs in states? Meet our calculator

This chart tackles two big questions: What are the emissions of a gas-powered car versus an electric car? And how do the emissions of an electric car change from state to state?

The Electric Road Trip is traveling and charging across 17 states in an electric car in September and October. As we travel, we track how many kilowatt-hours of electricity we gather from charging sessions in each state, based on Energy Department averages for each state's mix of generation. Creating electricity itself creates emissions — emissions that change drastically state by state. Minnesota's CO2 emissions per mile for each kilowatt-hour of power are well below Kentucky's, for example, because of the former's zero-carbon wind farm production.

Meanwhile, we're also comparing these numbers to the emissions for an average car with an internal combustion engine. (Here's a closer look at our gas versus electric and state versus state methodology.)

The Electric Road Trip will keep updating you over the course of this journey in the weeks ahead.
