EVs CO2 emmissions depends of the carbon intensity of electricity consumed.
So that is true that Germany with now 323gCO₂eq/kWh has a higher break even. But if you take the same data for exemple in France where electricity is much less carbon intensive, (now 32gCO₂eq/kWh), break even is as low as 15000km for an EV.
Germany should just emit less carbon for electricity generation.
Although France's electricity mix is exceptionally low, I'm surprised to see that the EU average (438gCO₂eq/kWh) is even higher than in Germany ([2], page 74).
In the US, it's over 600gCO₂eq/kWh, in China even 1,000gCO₂eq/kWh (1.3 million EVs were sold in China in 2020).
