Seems like a great tool to compare how dirty an EV is compared to an ICE car, but it’s giving the opposite results of what I would expect.
If you haven’t used/seen the tool before, it is here: [https://evtool.ucsusa.org/](https://evtool.ucsusa.org/)
So using the NEI site to tell me what the sources of electric generation are per state: [https://www.nei.org/resources/statistics/state-electricity-generation-fuel-shares](https://www.nei.org/resources/statistics/state-electricity-generation-fuel-shares)
If I were to compare Kansas (45% wind, 15% nuclear, 34% coal), with Kentucky (0% wind, 71% coal, 21% natural gas) I would expect to see Kansas with a much higher MPG CO2e, but instead, I see the opposite. I used a 2019 Tesla 3 Long Range AWD.
Kansas zip 66113, MPG CO2e=74
Kentucky zip 40475, MPG CO2e=82
Would someone please tell me what I am missing?
According to their tool:
## What is MPG-CO2e?
Shorthand for “miles-per-gallon carbon dioxide equivalent,” MPG-CO2e is a standard way to understand and compare emissions from electric vehicles. Specifically, it is the fuel economy a gas-powered car would have to achieve to generate an equivalent amount of pollution. A higher MPG-CO2e = less global warming pollution.
