Our recent study is on the front page of @derspiegel! Germany's most visited news website!

Translated title:
"Electric cars emit much less CO2 than assumed so far"

Let me give links to the original study and a quick article summary in English.

Here is a link to the study in English:

The initiative for the study came from @Oliver_Krischer and @DanielDholstein and they translated to German.
Thx guys!

It will be on their website in two hours.

I would also like to thank Christian Bauer of @psich_en.
I don't know him but he took the trouble to give it an informal peer review and concluded (translated): "The study is cleanly executed and explains plausibly how big the advantages of electric vehicles already are."

The first reason our study is positive, is because negative studies all use outdated battery emissions. E.g. the infamous IFO study uses a 2017 report that claims every kWh emits 175 kg CO2. The 2019 update is 85 kg. And @tesla its new impact study shows 77 kg in 2019.

The second is that car batteries and cars themselves last longer than often assumed. My analysis from EU data shows that modern cars last over 250 000 km on average. (Also in the US by the way.) More details in the study (see also the pictures.)

A disputed point is whether you should include the decreasing CO2 emissions of the car over the lifetime. Christian Bauer takes the current mix (400 gr/kWh) while I think you should make a conservative best estimate over the lifetime of the vehicle (250 gr/kWh). See also study.

Two points I always like to add:

1) Once EVs are produced using renewable energy you get to over 10x lower CO2 emissions. That's the goal.

2) Sharing smaller electric vehicles or biking is much better for the environment still.

Bottom line for me: don't trash talk the electric vehicle based on conservative and outdated assumptions but use up to date scientific data and you will see it scores much better in all EU countries already. /end

Nice spin off in the Dutch media: tomorrow at 7:15 I will be on Radio 1 and there will also be an article on the @NOS site around that time.

My new study regarding CO2 emissions also features in @tagesschau! tagesschau.de/wirtschaft/ele…
Scroll up this thread for a link to the study itself.

Here's a (Dutch) article on the @NOS website about our new study (see rest of thread) with the title:

Chair of @VWGroup Herbert Diess quoting my electric vehicle study!

I'm a huge fan by the way: I think if anyone manages to save the German car industry it's him.

An article in on @dagensindustri (apparently Sweden's best economics online site) for the collection.

An Italian article on @Auto21news. In the Google translation I 'take the pickaxe to' the theory that conventional cars emit less CO2. I kind of like that image.

Here's the official link of the party that requested the study.
I would like to stress that did not interfere with my sources and conclusions in any way. They had read my article in Joule and just asked me to update it and apply it to the German situation.
