This article is total nonsense. No data sources provided, claims 78g/Km CO₂ for Norway with 98% renewable energy. Also completely ignores energy use for production of fossile fuels and apparently uses the circulating wild guesses for CO₂ emissions during battery production (which Elon Musk has commented on...).
Without commenting on the figures of this article, generally EV CO2e footprint is manufacturing-heavy -> total lifecycle per-km footprint is still substantial without any emissions from charging energy.

The "total lifecycle CO₂-per-Km footprint" is a pointless and deliberately misleading figure when its basis of calculation is (almost completely) independent of the distance driven, but it suggests that driving the vehicle is subject to a high amount of emissions per Km. The opposite is true: EV lifecycle CO₂/Km becomes lower the more you drive.
Besides, deliberately including highly speculative CO₂ amounts from vehicle production and refuelling should be done in all cases: how much CO₂ is emitted by ships and satellite launches used in detection of crude oil reserves?
Vehicle wear and retirement is closely related to total distance driven, so when looking at EVs in the aggregate, a per-km perspective works fairly well.
I believe that the article is demonstrating some point, and this point is obvious. It's not a scientific article, and even though author does not provide information about data source that doesn't mean that there is no data source.
