Yep. Completely false. The in-use phase of ICE cars belches so much carbon that the car's construction phase carbon can safely be ignored in a first approximation of impact. The reason construction phase carbon is important in an EV is that it can be the only carbon that matters. When an EV is recharged exclusively from renewable sources, as many are, the use phase carbon is effectively zero. Which makes the construction phase important to measure, but the total lifecycle carbon impact of an EV can still be orders of magnitude less than that of an ICEV.
