There is a benefit as soon as the CO2 emissions per kilometer are lower.
Let's say the carbon intensity of electricity production here in Belgium is 100 gram/kWh right now. (This number varies throughout the day, depending on how much is being produced by "green" sources versus fossil fuels. Not just in Belgium, but also in the countries we import from. You can track those numbers on electricity maps[1].)
I can drive more than 5km with one kilowatt-hour, so that means the carbon intensity of my driving is (100 gram/kWh)/(5km/kWh) = 20 gram/km.
The typical emissions of a gasoline car is somewhere between 100 and 200 gram/km. So even though the grid here is not perfectly "green", I am reducing the emissions per km significantly by driving an EV.
Those numbers, and the conclusion, may vary depending on your car and grid. In places where a lot of inefficient coal plants are used, the carbon intensity of electricity production can be extremely high at times. Examples include Poland, India and some US states. In those places it may be better to drive a (very efficient) gasoline car instead of an EV, unless you are careful about when you charge.
