Germany has a law about saying things are free. Like, you can't say pizza delivery is free because it isn't - it's wrapped up in the price of the pizza. In that way, electric vehicles aren't emissions free because they're charged by polluting power plants (most of the time).

To me that's just typical German straightfowardness. You can drive it in a downtown where pollution and noise are strictly regulated. That's not to say that emissions don't happen elsewhere - to build the truck and to charge it.

Depends on how electricity is generated I'd assume.

I think it means while using it, smoke doesn’t come out of it. Maybe while charging some emissions happen ?

I mean yes, but actually no.

In this context it means that, on top of selling you trucks, they're also interested in upselling you by selling you chargers, charge management software, consulting you on power requirements, liaising with power companies... things of that nature, therefore helping you be emission free.

I thought it meant for local delivery services, as opposed to long haul.

Sounds like a tongue-in-cheek way of saying "EV generally has larger CO2 footprint but if you insist air in the city must be clean" to me as well.
