Zero emissions if and only if you draw a box around the vehicle and say, okay, from this point forward, zero emissions, from this vehicle.
Ignoring the fossil fuels needed:
- To generate its electricity
- To drive the massive mining vehicles needed for batteries and steel
- To fuel the ships bringing minerals and batteries from China
- For all the plastic components
- For all the steel components
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.
But here's the rub. Most EVs will need a new battery before then, resulting in even more of a carbon footprint.
EVs are silly. They're pure hype.
Hybrids are what the world needs. They actually have a lower footprint than that Dodge Ram.
But go on pushing this error.

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

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.

The video description for that TEDx (read: not TED) talk establishes that it has been flagged by TED themselves for violating their content guidelines against bad science.

Interesting... 21,000 vs. 125,000. Thanks. (Another source to consider.)

Hybrids aren't what the world needs, either. We need to design cities so that most people don't need a car at all. And that means trains, buses, metros, trams, bikes or ebikes (which make far more efficient usage of lithium than EVs do), high- and mid-density development rather than single-family homes, and walkable neighborhoods. Car-centric development is completely unsustainable regardless of what's powering the car.

If you like cities, live there.
Me, and many like me, view cities as nice to visit maybe twice in a decade, but we have no desire to live like that.
