So that source specifically states that the production emissions are a best estimate, and not thoroughly examined in the scope of that study. In the not-so-theoretical case where the grid is carbon free (there are locations in North America where this is very close to true) that completely changes the math on the production emissions. That study chose not to look at that, and instead choose a flat rate that reflected the current average.
Also, I’m not saying that electric cars are the proper solution; I’m saying they are the fastest solution. They are a stop-gap because the proper solutions are going to take too long to implement.
I think a bigger part of the production emissions come from further up the supply chain than the factory. Such as extraction, refinement and shipping of the lithium and cobalt required for batteries. That is also what makes it hard to estimate.
My point was that switching to EVs will not make transportation emissions disappear.
