Greenhouse gases (GHGs):

...

EVs reduce CO2 by 11%-100% compared with ICEs and by 24%-65% compared with
HEVs, and significantly reduce all other greenhouse gas emissions, using the U.S. grid
mix. If all U.S. cars were EVs, we’d reduce global warming emissions even on today’s
mostly coal grid. Using electricity strictly from coal, EVs still would reduce CO2 by
0%-59% compared with ICEs (two analyses found 0% change; seven others found
reductions of 17%-59%) and might produce 30%-49% more CO2 than HEVs (based on
only two analyses) on today’s grid. On the other hand, if electricity comes from solar or
wind power, EVs eliminate all emissions. Using natural gas to make electricity,
emissions fall in between those from coal and renewable power.
