Well, please show me a trustworthy study of the difference between ICE and EV emissions per mile during their lifetime. The ones I've read always say "in their lifetime", but they don't take into account EV batteries need changing after about 10 years .... And batteries are as we know the "big bad" of EVs. The absolutely only true comparison would be all emissions from all sources spread out over either per mile or per year. A combustion car can easily last 20 years, which isn't really a fair comparison to the 10 years.
Hey you made the claim in the first place, you have the burden proof. Don't attempt to shift it.
This article, and everying about this subject, presumes EV is better than ICE. That's the positive claim.
Show me the math, the studies. If it holds true, this should be easy. And, it would end the debate.
Data trumps. If the research is so overwhelmingly in favor of EVs, let's publish that info everywhere for people to read, study, analyze. Lots easier to convince people with the information out there, warts and all.
No, you'd hemm and haw and avoid the problem. We've been here before.
Well I claimed that I've not seen a study that accounts for all the different attributes at once. So there's really nothing for me to provide?
But if you really need it, MIT did a study in 2019 and they explicitly (in about 2 sentences) declare that they don't take into account battery lifetime, capacity degradation over time, battery efficiency's sensitivity to cold, the problem with disposing of depleted batteries. According to their study an EV has about 55% of the emissions of a traditional ICE of comparable size, not accounting for the aforementioned details, nor the fact that EVs replace batteries. I.e. they assume one set of batteries for the entire lifespan.
Now, I might very well be wrong. And I probably am (judging from the down vote bombing). But I just want to see a thorough study of both types of vehicles with everything taken into account from basically drawing board to junkyard.
No, you claimed:
Furthermore, when asked about a source for these claims, you come out swinging with the ever popular “no, you” defense.
Again, link your sources (MIT study) please.

Edit: Another link on batteries https://earth.org/environmental-impact-of-battery-production/
Great, it’s better if you link them where the claims were made though.
I hadn’t heard of earth.org so I looked them up: https://mediabiasfactcheck.com/earth-org-bias/
Not too bad. Though I’m well versed in battery tech and industry, it’s an incredibly dirty industry, coming with cited, fair sources is paramount.
Na mate, I asked first.
Conventional ICE can last 30 years, with engine and trans rebuild, which is trivial from a materials standpoint.
We have multiple 30 year old ICE vehicles that still get 30mpg, have air conditioning and unlimited heat.
EV will never compete with that unless we find new ways to make batteries.
