Earlier quoted context omitted.
One of the bigger arguments is also in the production itself can be not very eco-friendly, eg: creating the batteries themselves.
You are exactly right. People have a tendency to discount the production of the non-emission-generating thing in the first place. The energy and emissions required to build something like this is non-trivial. It should be mandated that if you want to appeal to green-fingered consumers with your marketing, you have to state the emissions deficit from which your product operates and how many years it would take to reco…
I commute in the summer on a Boosted Board, which uses most of the 99Wh battery to go one way (8km). My electricity in Ontario is largely nuclear and hydro, but say it's the worst case scenario and all the power comes from gas— the emissions from consuming 0.1kWh is ~35g CO2:

This is a far cry from what it would be driving that same distance in my Mazda 5, which would be a little under a litre of fuel (21MPG -> 11.2 L/100km), or 2.3kg of CO2, a 65x difference.
It's possible you're coming from a place of legitimate care, but honestly your comment sounds a lot like concern trolling to me. If there's anything out there which needs an "emissions deficit" sticker to help dissuade conscientious purchasers, lets start with private automobiles.
