I also vaguely remember what OP was talking about. It was also factoring in how dirty the energy was being produced was at the time. So if you add electricity is projected to be dirty for x decades plus the environmental cost of the battery manufacturing. But they probably redid the calculus recently as coal plants have been shutting down way faster than initially predicted.
Took the time to try to find more info on this.
Apparently it came from a 90 minute talk by a Toyota Australia executive. And the assumption is that the power grid supplying the BEVs are dirty in comparison to the hybrids which reduce CO2 in their power generation/efficiency.

This really smells of bullshit because it really doesn’t have anything to do with choosing one or the other.
We should be choosing BEVs and also putting tremendous effort on the power grid to go renewable energy.
I’ve come full circle on this statement after reading some more.
