From the article, first headline
The main problem is the German power mix with too much coal
As always, no study takes into consideration the energy mix today is different from the energy mix in next years
This chart is self explanatory, you just need a quick look to the increasing yellow area to notice what I mean
Renewables are increasing year by year, actually doubled in last 8 years (more or less), and coal is also being reduced, so those calculations wich didn´t take this into account are not real.
Also, I´ll bet an arm they didn´t consider either petrol and diesel cars emissions do increase with time. It´s very different an brand new ICE to that same engine after 50 or 100k km, with some play on many parts, bearings wich do not spin as smooth as when new, some soot/cinder in the combustion chamber and exhaust, etc.
Even if today EVs would be similar, to me main difference is they will pollute less year by year thanks to a cleaner power production year by year, while ICEs will pollute more year by year due to wear and use.
Not considering this is biased or flawed, and, coincidence or not
, I´ve yet to see one single comparison wich takes this into account
But thanks for the link RZS, it´s interesting
