As of two years ago the only country where that was the case was India. Right before that, South Africa and China both became clean enough for EVs to be an environmental net positive.
Power produced in the US is some of the cleanest in the world, and getting cleaner every day as coal plants are decommissioned. We are well above the environmental net benefit line.

There are no longer significant areas where this is the case. Even most coal markets in the US are clean enough (not sure what will happen with new de-regulations). The US, on average, is by far clean enough.
