I would hope that at some point the monicker ZEV would be retired.

Although there may be zero emissions at the tail pipe of the vehicle, the source of the electricity that charges the battery should be where it's measured and with the exception of Quebec, (mostly hydro electric) every other province and state uses a variety of fuel sources to produce the electrical power.  Everything from solar to nuclear to coal.

My suggestion would be that the Quebec premier really likes his name and photos in print and this is really just a sizeable political election contribution disguised as an event.
