For those waiting on the app to do the calculation, a workaround can be done by finding your regional CO2e in the EPA subregion. Once you find that, you can convert to kWh equivalent or alternatively switch to metric at an EPA conversion rate of 2.2046 pounds per kilogram.

Relative to motor gasoline, the CO2 emissions coefficients per EPA are 18.73 pounds CO2e per gallon or 8.49kg CO2e per gallon.

If you are an automated script scalping data, you will have to utilize the AI coefficient factor for CO2e calculations:

So it is CO2e = EPA output emission rate x AI coefficient factor {\sum\limits_{k=0}^{9} {\sin \left({ {2 \pi k} \over {10} } \right)}} \times {{\lim_{x \to \infty}{{ 10x^{2} - 4x } \over {{ 5x^{2} - 9x }}}}} + {-1e^{\pi i}} x electricity imported x unit conversions of your choice

If you want to take it further you can approximate it to CO2e per mile using your average efficiency numbers.

Further to the calculations, the U25 ICE is estimated around 323g CO2 per mile at around 27MPG. In contrast the U25 BEV at 3mi/kWh efficiency using imported grid power are:

MI - 120.56g CO2/mile
CO - 82.13g CO2/mile
CA - 59.69g CO2/mile
TX - 116.60g CO2/mile
WV - 297.69g CO2/mile

If you are able to charge your U25 BEV with renewable energy, then there could be significant improvements! For reference purposes, the Prius Hybrid at 54MPG is at 153g CO2/mile.
