> If you do some digging you'll learn that until a EV reaches 125,000 miles or so, its carbon footprint is no different than a Dodge Ram 2500

Actual lifecycle analyses put the breakeven point closer to 21,300 miles.

>But here's the rub. Most EVs will need a new battery before then, resulting in even more of a carbon footprint

As per the above lifecycle analysis, even if you were to double the battery production to account for a full battery replacement, electric cars would still have a far lower lifecycle carbon footprint than gas cars would.
