There's a study financed by EV sceptics Bosch, Honda, McLaren and Aston Martin doing the round, partly based on a study saying a Polestar takes 50k miles to emit less CO2.

Will debunk it this evening but could people maybe add links to places where it pops up?
I already know about @thetimes
And about daily mail. dailymail.co.uk/news/article-8…
And someone send me the study itself now. So where is this mentioned in the media?

Would love for you to send me links so I can debunk all those stories at the same time.

From #dieselgate you may know that carmakers get away with untruthful tests in the EU.

That's important for both scientists and consumers.

Here I explain on Dutch TV @kassa_bnnvara how these lies made taxi drivers buy the wrong EV:
bnnvara.nl/kassa/videos/5…

But there's more! Image
But it's not just bad for immigrant taxi drivers who see their entire livelihood threatened by the lies because they buy an electric vehicle with too little range and slow fast charging. It also leads to many more people dying of exhaust. Image
And finally it leads to combustion vehicles seemingly emitting less exhaust which in turn leads to newspaper stories claiming it takes 50k miles for an EV to emit less when it's already closer to 16k miles (and getting less all the time).

New 'study' claims it takes 48k miles for electric vehicles to emit less CO2 than gasoline cars.

But it's just a misleading brochure.
Reality is closer 16k miles.

UK media including @thetimes where mislead by this carmaker-paid attack on @BorisJohnson's green plans. (thread) Image
About me:

I research electric vehicles at @TUeindhoven and direct NEONresearch.nl.

Comparing CO2 emissions of electric vehicles and combustion cars is my specialty.

My paper describing common errors: sciencedirect.com/science/articl…

A recent report:

Here is @thetimes @GraemePaton reporting on 'a study commissioned by vehicle and technology companies' where 'researchers recorded results'.

And there's literally dozens of others who fell for this. ImageImageImage

@MLiebreich @Joost57437492 Everybody (well maybe 12 people so far) is asking me to debunk this article in the times. The problem: I don't know which study they are talking about. Can twitter help
thetimes.co.uk/article/electr…
Polestar published some numbers on it's study in september polestar.com/dato-assets/11…
and if I look at the @thetimes article they copy the numbers from that study. I briefly talk about that comparison here:
Main problems with this Polestar study:

1) The XC40 of parent company Volvo uses 45% more petrol than Polestar assumes if you take reality instead of WLTP.

2) The Polestar itself (not the battery) already emits 3 tonnes more. (Build next to a coal plant?)

I am sick and tired of of people who proclaim anti-renewable nonsense as fact and get away with it.

I think @mattwridley misunderstands @borisjohnson's green agenda on all 10 points but allow me to focus on the points regarding electric vehicles that are my academic specialty.
Matt Ridley is a journalist, biologist and viscount who owns coal mines on his family estate. He's (unsurprisingly) pro fossil fuels.
In this piece he gives ten things that are wrong with Johnsons green plans that I think mostly show how wrong he is himself.

Allow me to debunk a nonsensical scare story in the @spectator yesterday, claiming electric cars are impossible because they would lead to a complete replacement of the electricity grid.
spectator.co.uk/article/boris-…
We have another winner. Another retired professor (this time a physicist) who thinks he understands the green industrial revolution better than these young kids that come up with crazy ideas that are more inventive than insulation and driving less.
Prof Kelly laments that Boris Johnsons 'green industrial revolution' is doomed to fail.

Specifically:
'Nowhere is the flaw in the government's plan more clearly exposed than in the announcement that sales of new petrol, diesel and hybrid cars will be banned by 2030.'

* Selling Climate Change to Trump Voters *

I recently tweeted about telling the climate story better (). Now I want to take it to the next level.

I will use Haidt's research into the moral roots of liberals and conservatives and Pinker's into progress.
I think the first step is letting go of the hatred of progress that many 'progressive' intellectuals display. Here @sapinker (whose presentation I will use in the following tweets) says it eloquently.
This rejection of progress hampers our effort to address climate change. Instead of working on solutions people become numb and hopeless. Doom prophets should replace their smug negativity with some actual research and test their doom and gloom hypotheses.
