Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Emissions from building a EV is from memory less than the emissions from continuing to run an ICE car after only a few years. And rapid adoption would encourage more renewables into the grid and in homes further increasing the EV advantage.
Would that extend as far as mining, battery construction, and (probably) shipping components around the globe?
Usually these sort of studies include embodied emissions including all of the inputs that go into building the car. This article here: https://www.reuters.com/business/autos-transportation/when-do-electric-vehicles-become-cleaner-than-gasoline-cars-2021-06-29/
focuses on new-to-new comparisons, but if you subtract the embodied emissions of around 8M tonnes of CO2 for the model 3, it looks like the break even point using the US electricity supply in 2021 is around 4.5 years. And that is probably a bit conservative given that:
Of course, it also depends on how much the car is used. If you use a used ICE car extremely infrequently the crossover point will be later.
Here's a research article I have gotten around to reading yet but you may find interesting: https://www.sciencedirect.com/science/article/abs/pii/S095965262300269X

Nearly 14k miles is a lot for people in some locations. This is more or less what I was talking about. OP was throwing out random (trust me bro) figures, but the numbers I've seen are more nuanced, like these.
My point was basically that I thought their assertions were rather naive. I like the idea of electric, but not necessarily what I've seen out of the tech rn.
I'd also be curious how things worked over the life of the vehicle, and not some arbitrary tipping point early on in the x axis.
Battery replacement is usually going to be far more significant than 14k miles, but will have to happen. A standard carolla or camery can run for fucking ever with modest investment in care. All the care in the world won't protect you against batteries going belly-up.
Lithium batteries are far, far, far more reliable than a Toyota. It's not even a comparison.
How so? I've had Toyotas last me literal decades and hundreds of thousands of miles with minimal maintenance.
I have not encountered a battery in my life with that sort of stamina.
EV batteries are rated for 100K miles without any maintenance, and can often exceed that many times over.

You cannot run a Toyota more than 15k miles without maintenance. Usually it's just an oil change, but there are so many moving parts that need regular maintenance, and many engines will just up and die before a battery will.
EV cars also have rhe benefit of needing less brake maintenance, though that is offset by the tire wear and weight of long range EV cars.
Something like a Citroën Ami will probably wear out the interior before any mechanical component dies. Maybe some rare maintenance like a tire change.
Battery ratings are sort of like LED ratings. Under load they aren't worth shit.
Yeah, after all gas needs to be extracted distilled and shipped around the globe every time you fill up. Only to be burned at 20-30% efficency.
It's efficiently burned, but you only get to use 20-30% of the energy you buy, the rest is wasted as heat.
That isn't the same. I didn't ask about electricity (that would fuel the vehicle). I was pointing out that, among other things, batteries require mining in very specific locations, shipping raw components to where batteries will be built, building them, and shipping them to their destination.
Apples to apples (insofar that it is possible), my dude.
